This invention relates to a shock-proof device, in particular for use as an additional irreversible stage impact protection along with a constructive element for force transmission.

Know the use to protect damage to the shell plating of the vessel during emergency maneuvers, and when the mooring wall of the so-called fenders. Usually perform the function of the protective body cranes is located between the vessel and the quay wall, so that it serves, on the one hand, as a shock absorber and, on the other hand, as spacers to prevent the friction of the hull. For large vessels is used as a rule, independently mounted fenders, which are a component part of the berth. Such executed as part of a pier fenders can be made to a certain extent elastic, so that they can to some extent compensate for the movement of the vessel when docking or excitement.

However, if it exceeds the elastic damping capacity used Krantz there is a danger of damage to the shell plating of the vessel, as arise, for example, when not locked kick vessel at quay wall impact energy acts without depreciation on the outer wall of the vessel. To prevent this scenario, damage the value of the shell plating of the vessel can be provided irreversibly acting shockproof device, which if exceeded, the dampening used Krantz is triggered and then absorbs at least part of the emergent energy of impact or, respectively, converts into work of deformation and heat.

Usually, depreciation impact efforts and effective absorption occurs when the collision impact energy is a problem, in particular, when a moving object on the basis of the mass of the object it is necessary to take into account the high energy of motion, which are absorption predetermined, when the predictable course of events.

This applies not only to ships such as oil tankers, for which as a component part of the berth you must provide a shockproof device, but also to rail vehicles. From rail known in the art, for example, travel stops, which serve as a complete path, respectively, dead-end road railway line and to prevent overrunning of the rail means or wagon for the end rails. Travel stops in most cases designed in a way that can be perceived as possible amount of energy moving rail means to a rail vehicle remained possible unharmed. When this limit stop can be deformed or destroyed.

However, shockproof device which you can use also as shock absorbers. When it comes to structural elements on the vehicle, which in the case of collision or collision with obstacle take energy and thereby to prevent damage to the vehicle or cargo. The shock absorbers are found primarily on rail vehicles (also called "buffer", "buffer device" or "tted beam"), while in most cases used one or two located on the end sides of the structural element in order perception affecting rail means in its longitudinal direction on the outside of horizontal compression forces. In principle you can use in rail vehicles as shockproof device two types of absorbers, namely the so-called single buffers or Central buffers when shockproof device is located on the longitudinal axis of the vehicle, so that on each side rail of the vehicle is only one buffer in the middle of the head of the cross, or the so-called double buffers or side buffers, when the side rail of the vehicle are two buffers.

In line with this, of railway engineering, it is known, for example, supply consisting of several the any state is the rail vehicle private car bodies of the so-called lateral buffers or buffers, UIC, when the bodies of the cars are not connected to each other through a swivel truck, and thus, the movement may change the distance between the two connected to each other by the car body. These side buffers are used for perception and damping associated with normal movement, for example, when braking or pulling away, shock.

For used in the rail vehicle side buffer can be used telescopic design, which has a body buffer, placed in it the element of force, and a damping element, such as a spring or elastomeric body. In this design case, the buffer serves as a longitudinal guide for the perception of lateral forces, while placed in the frame buffer damping element is used for transmission in the longitudinal direction.

Constructive length, and the progress of the buffer, i.e. the deflection of the damping element, standardized for different categories of vehicles in the European instructions (e.g., memos UIC 526, 528). The course standard buffer UIC lies, for example, in the range from 100 to 110 mm At the maximum stroke buffer damping ability of the side buffer is exhausted, resulting in exceeding the characteristic workload impact efforts are not damped the I in the truck of the vehicle.

Due to this, although the impact of the efforts that occur during normal movement, for example, consisting of several parts of the vehicle, and between the car body, are absorbed through integrated in the side buffer is executed, as a rule, regenerative damping element, however, if it exceeds the working load side of the buffer, for example, upon impact of the vehicle against an obstacle or when braking the vehicle, usually integrated in the side buffer damping element is not sufficient to absorb all that energy. Due to this, provide lateral buffer damping shock no longer fit into the concept of energy absorption of the whole vehicle, so that the resulting impact energy is transmitted directly to the truck of the vehicle. However, it is subject to these extreme loads and can be damaged or even destroyed.

To prevent such damage from equipment rail transport already know this embodiment the guides of the tubular parts of the buffer that after exhaustion of the maximum stroke of the buffer, i.e. after the arrival of the guides of the side parts of the buffer (tube buffer or follower buffer) to set the fence, you have the additional option of their koroch the deposits at a controlled deformation.

For example, in WO 2005/11 58 18 A1 describes a tubular buffer, in which, after exhaustion of the possibilities of reception of energies is made regenerative damping element break the connection specified destruction, to thereby increase the length of the shortening of the buffer. This increased length shortening provides the possibility of plastic deformation of the buffer when overloaded, so this solution destructive ensures the conversion of the impact energy to the work of deformation and heat. Thus, using occurs when you overload deformation buffer provides impact protection in addition to provide lateral buffer damping of shock.

Even when known from the prior art side buffer can to some extent protect the truck of the vehicle from damage from bumps during raids, while it is impossible to reconcile this with additional protection against impact with certain applications. For this purpose it would be necessary to provide the respective characteristics based forces from the path by deformation of the buffer to ensure a predictable, predetermined energy absorption. In particular, the known solution is not suitable for many applications, as achieved by deformation of the buffer maximum tap owenie energy is often too small.

Another disadvantage is that after activation of the additional protection against shock the whole side of the buffer should be replaced because shockproof device integrated in the side buffer, and due to deformation of the casing side buffer shall not be more use for normal movement.

The above problems are related not only to the shock-proof device, which is made in the form of a shock absorber, i.e. in the form located on the end side of the rail vehicle structural element. Mentioned as an example of the shortcomings in the figurative sense are also shockproof devices that are, for example, a part of the limit stop or component part of the berth.

On the basis of the above issues in the framework of the invention is the creation of a shock-proof device, by which, on the one hand, to reliably absorb high impact energy and with which, on the other hand, the characteristic dependence of the force from the path shockproof device can accurately be agreed with individual applications.

Additionally, shockproof device must be suitable for retrofitting, for example, the face side of the car body, the face side of the limit stop or pier when these is Ananiah to date have not provided destructible impact protection.

Underlying the invention the problem is solved using a shockproof device while it is shockproof device includes: a main plate; a transmission element efforts with a clamping element; element absorption of energy in the form of a deformable tube, through which the first end region connected with the main plate; and a connecting element for detachable connection element is transmitted from the second end region of the deformable tube, while the connecting element has on the clamping element pressure, so that the deformable tube is clamped without a gap between the clamping element and the main plate.

In one possible implementation shockproof device, it may further be connected to the main plate carrier frame, with the deformable tube is placed in a frame, and the connecting element is designed for the connection element is transmitted with the carrier frame, on the one hand, and with a deformable pipe, on the other hand, while the connecting element is preferably connected to the carrier frame Rethimno and clicks in your United with the carrier frame condition on the clamping element, so that the deformable tube is clamped without a gap between the clamping element and the main plate.

It should be noted that the invention should be seen not only in what we offer SS is nitella impact protection when used in the side buffer. On the contrary, shockproof device is generally suitable for any end surface of the bearing structure, as, for example, for the face or contact surface of the pier, the limit stop or structural element of the vehicle, which serves to transmit movement of the forces. In particular, the structural element of the vehicle may be, for example, passing in front of the front side of the car body a transverse beam, which is made, for example, as described in DE 10 126 483 A1, in the form of arcuate buffer and through the elements of the energy absorption and the reference beam mounted on the side rail of the vehicle and serves to protect the end faces of the body of the car from calling strikes damage.

As a structural element for transmission of force" in the sense of the present invention are also possible before passing across the front side of the car body support structure, through which the elements of the energy absorption is connected with the front side of the car body. This support structure may additionally serve as a support on the opposite side of the car body side coupling systems, such as, for example, coupling the middle of the buffer.

Thus, the solution according to the invention is shockproof device before is oznaceno for use in combination with a constructive element for force transmission and is used for conversion in the event of a collision due to a given plastic deformation accommodated in a frame of the deformable tube the emerging of the impact energy to the work of deformation and heat. Through the use of sandwiched no gap between the clamping element and the main plate deformable tube can be pre-set actuation force and the maximum value of the absorbed energy shockproof device and specifically to coordinate with certain applications. Accordingly, it is possible to specify not only the response characteristics, but also the course of events in the absorption of energy.

Under used here, the term "clamped without gap" is to be understood that during normal movement of the clamping element is essentially rigid relative to the main plate.

The solution according to the invention is characterized, in particular, the fact that the shockproof device has a construction which enables, after tripping shockproof device, plastic deformation is only possible located in a frame of a deformable tube. Thus, in the event of a collision it is necessary to replace only this structural element. For this purpose, the connecting element that connects the element is transmitted with the carrier frame, on the one hand, and with a deformable pipe, on the other hand, is connected Rethimno with the carrier frame. Due to the separation (split) connection between the connecting element and bear is her frame can be extracted deformable tube of the shock absorbing device and replace if necessary. Then the connecting element again connect with deformable pipe and/or possibly with the carrier frame so that it exerts pressure on the clamping element, and (e.g., replaced) deformable tube is clamped without a gap between the clamping element and the main plate.

In particular, the solution according to the invention is also characterized by the fact that in the event of a collision does not require full replacement used for the transmission of structural elements.

When this element is transmitted, which is used in the shock-proof device according to this invention serves as the connection point between the structural element for force transmission and shockproof device. Detailed description of the transmission element efforts below.

Preferably shockproof device configured to transfer impact efforts, thus resulting in the transmission of shock to the efforts of the power stream passes through the transmission element efforts, the clamping element, the deformable tube and the core plate. This deformable pipe must be designed so that up to a predetermined characteristic of the impact force, essentially fully transmitted incurred in the transfer of impact energy efforts. After exceeding the predetermined characteristic of the impact force of the deformable tube must when one is belt plastic deformation to absorb and damp, at least part occurs when the transmission of shock energy efforts, while plastic deformation of a deformable pipe element is transmitted and the main plate provide relative movement towards each other. Due to the fact that generated during the transmission of impact efforts in the longitudinal direction shockproof device of power flow, essentially, fully exposed, among other things, through a deformable tube, it is possible to precisely specify in advance the energy absorption of a deformable tube and, in particular, characteristic of a deformable tube power operation, by performing a deformable tube.

In particular, it is possible due to the wall thickness of the deformable tube and/or by appropriate selection of the material in advance just to set the bending strength of a deformable tube and thus characteristic of a deformable tube power operation. Naturally, it is also possible that formed during the transmission of impact efforts in the longitudinal direction of the anti-shock device power flow only partially passes through the deformable tube, while the remaining part of the power flow is bypassed to the bypass deformable pipe using suitable devices, so this part takes place directly, i.e. bypassing the deformable pipe element transmission effort to the main plate.

In one preferred realization of the shock absorbing device is provided that is contained in a shockproof device element energy absorption made in the form of a deformable tube, which if exceeded, the transmitted power flow through shockproof device specified amount of energy plastically deformed preferably with the extension of the cross-section and allows relative movement of the transmission element efforts relative to the main plate. Shockproof device, in which as part of the absorbed energy is used deformable tube, characterized by the fact that it has a given actuation force without peak power. Thus, on the basis of passing essentially rectangular characteristics are achieved after activation shockproof device, the maximum energy absorption.

Particularly preferably, when triggered, shockproof device of the deformable tube is plastically deformed with the simultaneous expansion of the cross-section. But, of course, it is also possible energy absorption with simultaneous decrease of the cross-section of a deformable tube; however, for this it would be necessary, for example, to squeeze the deformable tube through the inclusion in the base plate shockproof device coplowe about the opening, etc., so plastically deformed element absorption energy is squeezed out of the shockproof device. In a deformable tube, which is plastically deformed when triggered shockproof device when the expansion of the cross section, it is possible to prevent such ejection of the deformed element energy absorption. Therefore, an embodiment with a deformable extension cross-sectional element of the energy absorption is at present preferred.

In the solution according to the invention provides that the deformable tube is sandwiched no gap between the main plate and the clamping element. This ensures backlash-free integration of deformable tubes in a shockproof device, due to a suitable pre-stressing can be influenced or, respectively, the pre-set characteristics of the actuation of the deformable tube and thereby shockproof device. As the clamping element can be, for example, the stage, resting in facing the base plate thrust surface of the coupling element. While this step can be performed as an integral part of the element is transmitted.

However, as an alternative solution, perhaps a solution in which the clamping element is made about the relative element is transmitted in the form of a separate structural element and has for example, placed at least partially made in the form of a hollow body element force transmission body of the clamping element, with the body of the clamping element is made of the stage, facing the facing the base plate thrust surface of the coupling element.

In one preferred realization of the solution according to the invention the opposite base plate end of the deformable tube is placed preferably with geometric circuit formed in the connector groove. When the connecting element is preferably connected via a detachable threaded connection with the carrier frame and thereby presses the clamping element so that the deformable tube is clamped without a gap between the clamping element and the main plate.

The connecting element serves not only to clamp the deformable tube between the clamping element and the main plate, but also performs the function of a longitudinal guide, when after tripping shockproof device is plastically deformed deformable tube, and a transmission element of the effort is moved to the main plate. For this purpose, the connecting element preferably has a guide surface which directly borders or, respectively, adjacent to the outer surface of the element is transmitted and which is done is on with direction after actuation shockproof device caused by plastic deformation of the deformable pipe movement transmission element efforts relative to the base plate in the axial direction shockproof device. Due to the fact that the connecting element also performs a guiding function, it is possible to prevent jamming or misalignment of the individual structural elements shockproof device when the energy absorption. Thus, it is possible to prevent, in particular, vertical or inclined, i.e. not fully axial load, "seizing" or, respectively, jamming, so that in principle is firmly set function of energy absorption with the destruction of pre-defined events.

As mentioned above, by appropriate selection of the wall thickness and the material of the deformable tube can be pre-set value transmitted in the transmission of shock forces with the help of the power flow through a deformable tube, the characteristic response of a deformable tube or, respectively, shockproof device energy. In another particularly preferred realization of the shock-proof device according to the invention provides that the deformable tube is connected with his converts to the main plate end with the main plate with closure material and/or geometric circuit. When this base plate may be provided with a corresponding groove into which the deformable tube.

On the other hand, at the opposite end of Defoe is Miramas pipe preferably includes a deformable section of the pipe, compared with lying further in the direction of the main plate section of a deformable tube has an enlarged cross section. In this embodiment, the shockproof device must have additionally, the tapered ring so that the deformable tube is clamped by means of this conical ring between the clamping element and the main plate. This conical ring can be performed, for example, in the form of a single whole with a clamping element. This, of course, you can perform the tapered ring in the form of an individual relative to the clamping element structural element.

In principle, the tapered ring should be, at least partially, its located on the side of the main plate end section in the advanced section of the deformable tube and snugly against the inner surface of the deformable tube.

Achieved with this modification, the advantages are obvious. On the one hand, by providing a deformable tube, which is clamped by means of a conical ring between the main plate and the clamping element is created shockproof device that enables maximum energy absorption at a smaller installation space.

Through the use of a deformable tube, which is plastically deformed by expansion of the cross-section, mortality is t, in particular, the need to provide additional space behind the shockproof device, which is pushed plastically deformed deformable pipe after tripping shockproof device. On the other hand, in this embodiment, by providing a tapered ring between the clamping element and the deformable tube can be very precisely pre-defined sequence of events when the energy absorption.

As mentioned above, the tapered ring should be, at least partially, its located on the side of the main plate end section in the area of the deformable tube, the cross section of which is already before tripping shockproof device is compared with lying further in the direction of the main plate section of a deformable tube enlarged cross-section. Because, on the one hand, the tapered ring at least partially protrudes into the widened section of the deformable tube, and, on the other hand, playing in the advanced section of the deformed tube portion of the conical ring adjacent to the inner surface of the pipe section, when triggered, shockproof device, i.e. when the element is transmitted together with the clamping element moves relative to the base plate and connected to the main plate with zamykanie material and/or geometric deformable circuit pipe in the direction of the base plate, it is located on the side of the main plate end of the conical ring moves along the inner surface (yet) extended area of the deformable tube and causes thereby the axial direction of the absorption of energy. In addition to provide a guide surface of the coupling element direction, is provided with a cone ring axial guiding action prevents the misalignment of the clamping element or, respectively, the tapered ring when triggered shockproof device in a deformable tube, so that the plastic deformation of the deformable tube (i.e. plastic expansion of the cross-section of a deformable tube) is accurately predicted image, and provides the ability to accurately predict the overall course of events the energy absorption in the event of a collision.

In the last named embodiment, it is possible to perform the tapered ring and the clamping element in the form of a single whole. But, of course, also possible that the tapered ring is connected with the clamping element, namely formed on the clamping element stage, which ends in facing the base plate thrust surface of the connecting element, by means of geometric circuit or by connecting with the power circuit.

In one particularly preferred implementing the tion shockproof device according to the invention is provided, that element of the power transmission has on its opposite base plate side of the impact plate, through which the impact of the efforts transmitted to the transfer control effort and thus in anti-shock device. This impact plate can be directly connected to the transmission element efforts, so that the impact of the focus from the impact plates directly through the transmission element efforts in anti-shock device. This variant execution is characterized by the fact that the shockproof device is designed to transmit not only the impact efforts, but also tension. When transmitting tension through shockproof device resulting power flow passes through the strike plate, the transfer control efforts, the clamping element, the connecting element and the base frame.

In another preferred realization of the shock absorbing device is provided, it is additionally integrated into the shockproof device, the buffer device. This buffer device preferably contains sent in is made at least partially in the form of a hollow body element force transmission buffer plunger with a shock plate, which is provided on the opposite base plate end shockproof device and which is designed for insertion through puff the NSS unit impact efforts to transfer control efforts and shockproof device. Also integrated in this embodiment, in a shockproof device, the buffer device must be placed inside the element of the power transmission is preferably a regenerative element energy absorption.

Thus, in this preferred embodiment, the shockproof device is used in combination with, for example, is usually applied as a lateral buffer buffer device. This buffer device serves as the executed regenerative shock absorber, which are absorbed, respectively, are damped occur during normal movement, for example, in the iterative vehicle between the individual bodies of the cars strike force. When exceeding the workload executed regenerative and integrated into the buffer device of the damping element (regenerative executed element energy absorption) is located after the buffer device shockproof device, in this case, because a given plastic deformation under shock-proof device of a deformable tube, the impact energy is converted into work of deformation and heat. Thus, regenerative performed damping element (a spring-loaded device), as well as other parts of shockproof mouth of the STS can be reliably protected from destruction or damage in the event of a collision.

In the solution according to the invention after activation shockproof device must be replaced only plastically deformed deformable tube as a separate structural element.

As a buffer device, you can use the design described, for example, in EP 1 247 716 D1. It is particularly preferable that the buffer device has a capability of absorbing or damping up to a pre-defined characteristic of the impact force with simultaneous longitudinal shifting of the buffer plunger in the direction of the base plate occurring when exposed to the impact plate of impact energy, while the exhaust stroke of the buffer device power stream passes directly from the impact plates through the transmission element efforts, the clamping element, the deformable tube and the core plate.

In one particularly preferred embodiment, the last named modification in which shockproof device is additionally integrated into the shockproof device buffer unit, provided that the main plate shockproof device made in the form of a flange, is made with the possibility of installing preferably Rethimno on the front of the wagon. Thus, while we are talking about is combinatii shockproof device according to the invention with a buffer device, while this combination is designed to be installed with the flange of the main plate on the front of the wagon. In line with this, shockproof device with an integrated buffer device can be installed as a fully exchangeable site on a frame or bogie wagon. When it comes to a buffer device with a shockproof device, which is made in the form of a module, i.e. as replaceable completely functional group. Thereby, it is possible to provide, for example, to the side of the buffer as a constructive element for force transmission additional shockproof device. When shockproof device is used in combination with a buffer device, the buffer device serves as a regenerative made of shock absorber, which are absorbed or, respectively, are damped occur during normal movement, for example, in the iterative vehicle between the individual bodies of the cars strike force. When exceeding the workload regenerative completed and integrated into the buffer device of the damping element is triggered on after the damping element deformable pipe shockproof device, thereby using the specified plastic deformation is formiruemoi pipe impact energy is converted into work of deformation and heat.

Above was the description of particular scenarios, in which shockproof device additionally has integrated anti-shock device, the buffer device, with shockproof device is made with possibility of installation, preferably Rethimno, with the flange of the main plate on the front of the wagon. However, in the context of this invention, of course, it is also possible that the shockproof device is not provided with an additional buffer device. For example, in principle it is possible that the transmission element efforts shockproof device at its opposite base plate side has a shock plate, through which you can enter directly impact efforts of the impact plates in the element is transmitted and thereby shockproof device. This main plate shockproof device may be made in the form of a flange, is made with possibility of installation, preferably Rethimno, on the face side of the car body. Thus, in this embodiment, we are talking about additional (pure) shockproof device that does not have the property of deformation and preferably is intended for installation on the front of the wagon.

In another preferred implementation of rotigotine device integrated in passing through the front end side of the car body crossmember so, what carrier frame, at least partly housed in under the cross beam extraction. This passing in front of the front side of the car body a transverse beam may be, for example, arcuate buffer described in DE 10 126 483 A1. This shockproof device serves as a lateral connecting elements impact beam with the load-bearing structure of the car body. Thus shockproof device may also have, when it is above the integrated buffer unit, damping properties.

In another preferred embodiment, the last named of implementation, in which shockproof device integrated in passing through the front end side of the car body cross-member, provided that the main plate and/or the carrying frame made in the form of an integral component of the transverse beams. This element of the power transmission should preferably be connected via its flange opposite the main side plate bearing structure of the car body.

But, of course, it is also possible that passing in front of the front side of the car body a transverse beam is made not in the form of arcuate buffer in the sense of DE 10 126 483 A1, and in the form of a carrier structure. On the opposite shockproof device side of this carrier is tructure can be placed average buffer coupling, etc.

To do this, shockproof device 100 according to the first variant has run made in the form of a flange of the main plate 1 made by opportunity set and, for example, using screws (not shown) of the bearing structure. While in the base plate 1 is provided preferably through holes 16 through which may be used for attaching the shock absorbing device 100 screws.

Shockproof device 100 according to the first variant implementation consists of the carrying frame 2, which is still connected with the main plate 1. Namely, the base frame 2 in the shown embodiment is made in the form having a round cross-section of the pipe segment. Inside the supporting frame 2 is deformable pipe 5. This deformable tube 5 abuts against his converts to the carrier structure by the end of the main plate 1 and fixed there by using is shown in Fig.7. the grooves 18.

In addition, shockproof device 10 has the element 3 is transmitted in the form of a tubular body, while on the opposite base plate 1, the end of the element 3 is transmitted is fixed impact plate 11. Located on the side of the base plate the end of the element 3 is transmitted still connected to the clamping element 4.

In the shown embodiment, the clamping element 4 is performed separately on element 3 of the power transmission element, which has a body 4A of the clamping element and formed on the body 4A is mounted on a stage 4b. Tel is 4A of the clamping element acts, at least partially inside facing the base plate 1 element 3 is transmitted, while step 4b of the clamping element stands for the end side facing the base plate 1 of the end of the element 3 is transmitted. Required between the element 3 is transmitted and clamping element 4 fixed connection is preferably formed by connecting with a circuit material between the body 4A of the clamping element and the inner side of the element 3 is transmitted.

Element 3 is transmitted to rigidly United at located on the side of the main plate end clamping element 4 is held by means of a connecting element 6 mounted on the main frame 2 shockproof device 100. For this purpose, the connecting element 6 has a thrust surface 10 (see figure 5), which rests against the opposite base plate 1 side is formed on the body 4A is mounted on a stage 4b.

On the other hand, on the clamping element 4 is placed a conical ring 9 which is a conical ring 9 serves for clamping the deformable pipe 5 between the main plate 1 and the element 3 is transmitted by using the provided located on the side of the main plate end clamping element 4. Although in the drawings the clamping element 4, the conical ring 9 and the element 3 is transmitted is shown in the form of corresponding separately you anenih structural elements, naturally, it is also possible to perform these elements of the clamping element 4, the tapered rings 9, item 3 is transmitted or at least part of these elements as a whole.

As shown in particular in figure 5, which shows the detail shown in figure 2 shockproof device 100 opposite to the base plate 1 to the end of a deformable tube 5 is placed in the formed in the connecting element 6 groove 6A. Himself the connecting element 6 Rethimno connected by means of a screw connection 15 with the carrier frame 2. In the shown connected state of the connecting element 6 resistant surface 10 of the connecting element 6 presses on stage 4b of the clamping element 4, while the force pressing (pre-tension) is transmitted through the conical ring 9 facing the element 3 is transmitted to the deformable end of the pipe 5.

Facing the element 3 is transmitted to the deformable end of the pipe 5 is compared to lying in the direction of the main plate section of enlarged cross-section. In this extended section of the deformable tube 5 is at least partially conical ring 9 together with formed on the clamping element 4 step 4b, so that the conical ring 9 is attached to the inner surface of the extended section of a deformable tube. As mentioned above, thereby the conical ring 9 performs the functions of direction triggered shockproof device 100 longitudinal shift element 3 is transmitted in the direction of the base plate 1.

Other guiding function provided on the connecting element 6 guide surface 7, which is adjacent to the outer surface of the element 3 is transmitted.

Shown in figures 1 and 2 embodiment of a shock absorbing device 100 according to the invention is used for plastic perception of energy in the event of a collision, and the perception of energy takes place with a constant power level. Power operation and power level can be adjusted by the degree of prior deformation of the deformable tube 5 at its opposite base plate 1 end, and a wall thickness of the deformable tube 5. When in the event of a collision, i.e. when exceeding the characteristic in the transmission of shock forces to the deformable tube 5 power actuation element 3 is transmitted with the provided at its located on the side of the main plate end clamping element 4 and a conical ring 5 is in a deformable tube 5, through which a deformable tube 5 is plastically deformed by expansion of the cross-section. Achieved by using shockproof device 100 energy absorption exhausted, when the element 3 is transmitted to its located on facing the base plate end clamping element 4 and a conical ring 9 abuts against the main plate 1.

In the solution according to the invention of th the collision must be replaced only plastically deformed deformable pipe 5, while the rest shockproof device 100 can again be applied. To facilitate replacement of a deformable pipe 5 connecting element 6 is preferably connected by means of a screw connection 15 with the carrier frame 2.

Figure 3 shows a second embodiment of a shock absorbing device 100 according to the invention in isometric projection. Figure 4 shows a lateral incision is shown in figure 3 shockproof device 100. Items used in shown in figure 3 shockproof device 100 according to the second variant implementation of a deformable tube 5 shown in figure 5.

As shown in figures 1 and 2 shockproof device 100, shock-proof device according to figure 3 is made with possibility of installation in the form of fully interchangeable functional group on the end side of the support structure. However, unlike described with reference to figures 1 and 2 of the first variant of the run, the second run has, as shown in figure 3 and 4, an additional damping function. To do this, in element 3 of the power transmission integrated buffer unit 12. As shown in figure 4, the buffer device 12 has, essentially, buffer plunger 13, while on the opposite base plate 1 the end of the buffer plunger 13 is shock plate 11. The buffer plunger 13 is at least partially in ispolnennom in the form of a hollow body element 3 is transmitted and through the inner wall element 3 is transmitted is directed in the axial direction.

In addition, the buffer device 12 may be placed inside the element 3 is transmitted preferably regenerative executed element 14 energy absorption (for example, the elastomeric body), which serves to absorb and thereby damping moderate impact efforts. The term "moderate impact efforts" should be understood drums efforts, which arise, for example, during normal movement and are entered in the impact plate 11.

When exceeding the workload placed inside the element 3 is transmitted, preferably regenerative executed element 14 energy absorption buffer unit 12, a loading plate 11 hits in the opposite base plate 1, the end of the element 3 is transmitted, resulting in stroke occurs when the flow of power is transmitted directly from a striking plate 11 in the element 3 is transmitted. Thus, in the future, resulting in the transmission of shock to the efforts of the power stream is directed through the element 3 is transmitted, the clamping element 4 or, respectively, stage 4b of the clamping element 4, the deformable tube 5 and the main plate 1.

To a pre-specified characteristic power stroke deformable pipe 5 is essentially rigid connection. However, if it exceeds characteristic of a deformable tube 5 impact force deformable true the and 5 loses its function of force transmission, when simultaneous plastic deformation of the deformable tube 5, at least part occurs when the transfer of a shock the efforts of the energy is converted into work of deformation and heat and thereby extinguished. Due to the plastic deformation of the deformable tube 5 element 3 is transmitted is moved relative to the base plate 1 to the base plate 1.

In shockproof device 100 according to the invention the characteristic response of a deformable tube 5 the impact force must be chosen so that only after exhausting the possibilities of energy absorption due to item 14 energy absorption buffer unit 12 occurs by plastic deformation of the deformable tube 5.

A second embodiment of a shock absorbing device 100 according to the invention forms a fully remanufactured node, which is made with possibility of installation on the carrier structure, for example, the body of the car. Thus, we are talking about a shockproof device by integrating the buffer device 12 is also in the normal movement of property effective damping. Integrated anti-shock device 100 buffer unit 12 can be, for example, as a regenerative made of the shock absorber, in which during normal movement, for example, in the iterative vehicle absorbance who are stated or respectively, are damped arise between the car body percussion efforts. However, if it exceeds workload regenerative completed and integrated into the shockproof device 100 of the damping element 14 of the buffer device 12 is triggered located after the buffer unit 12 unit of energy absorption (deformable tube 5) shockproof device 100, due to a given plastic deformation of the deformable tube 5, the impact energy is converted into work of deformation and heat. Thus, regenerative made of the damping element 14 of the buffer device 12, as well as other constructive elements shockproof device 100 is effectively protected from destruction or damage in the event of a collision. After actuation shockproof device 100 must be replaced only deformable pipe 5.

Figure 6 and 7 shows in isometric projection side shockproof device 100 according to the third variant of implementation of the present invention. Shockproof device 100 according to the third variant is shown on the side view on Fig.

A third embodiment of a shock absorbing device 100 according to the invention in the structural and functional relationship in principle comparable with the first variant implementation, shown in Figi 2. In short, the third embodiment of is shockproof device for plastic perception of energy in the event of a collision, using a deformable tube 5, which, upon actuation shockproof device 100 expands due to plastic deformation. In contrast to the first variant of implementation described above with reference to figures 1 and 2, shockproof device 100 according to the third variant of execution serves as a structural element of the power transmission, which is located between, for example, is not depicted in Fig.6-8 carrier structure, for example, the main frame of the car body and located in front of the bearing structure component.

To do this, shockproof device 100 according to the third variant of execution has the base plate 1 through which the shockproof device 100 can be Rethimno mounted on the carrier structure. While in the base plate 1 may be provided with apertures 16 for the reception of screws, pins, fingers, etc. that ultimately serve for fastening the base plate 1 on the carrier structure.

However, instead of the through holes 16 can be used as the fastening means are also other solutions. When, for example, for constructive reasons, the main plate 1 may be provided with only otnositelno small regional area, in which there is no sufficient space for appropriate through holes 16, or, respectively, when there is not enough space for screws, pins, etc. that should be included in the through hole 16, it is possible on the rear side of the base plate 1, i.e. on the side of the base plate 1, which is the opposite of the carrier frame 2, weld or otherwise fasten the pipe, in the end, this pipe is used for mounting the shock absorbing device 100 on the carrier structure.

Unlike the first option run in the third embodiment of the present invention shock plate 11 is made as a base plate, on which can be mounted in front of the bearing structure of the structural element. With this as a basic plate 1 made as the base plate impact plate 11 may have a through hole 19, through which can pass the appropriate fasteners for the mounting of using these fastening elements located in front of the bearing structure of the structural element.

Below is a detailed description of the operating principle shown in the section on Fig shockproof device 100 according to the third variant of execution.

Shockproof device 100 according to the third variant of execution is already above the main boards is 1, and also above the impact plate 11, so that the shockproof device 100 may serve as a connecting link for connecting the bearing structure located in front of her constructive element. With the main plate 1 is connected, preferably Rethimno, the support frame 2. For this purpose shown in Fig embodiment are suitable for this screw connection 20. As in the first embodiment, the supporting frame 2 is made in the form having a circular cross-section pipe section. Inside the supporting frame 2 is deformable pipe 5, which his converts to the carrier structure by end abuts against the main plate 1 and there is fixed, for example, by using grooves. The opposite end of the deformable tube 5 is an enlarged cross-section, which is held in the clamping element 4. The clamping element 4 is a structural element that has a body 4A of the clamping element and formed on the body 4A is mounted on a stage 4b. The body 4A of the clamping element is at least partially inside facing the base plate 1 element 3 is transmitted, while step 4b of the clamping element stands for the end side facing the base plate 1 of the end of the element 3 is transmitted. Element 3 is transmitted with rigidly fixed on the location is largely on the side of the main plate end clamping element 4 is held by means of a connecting element 6 mounted on the main frame 2 shockproof device 100. For this purpose, the connecting element 6 has a thrust surface 10, which abuts the opposite base plate side is formed on the body 4A is mounted on a stage 4b.

On the other hand, the clamping element 4 is placed a conical ring 9 which is a conical ring 9 serves for clamping the deformable pipe 5 between the main plate 1 and the element 3 is transmitted with the provided on the side of the main plate end clamping element.

Design shockproof device 100 leads to the fact that the transfer drums efforts between the flange shock plate 11 and the main plate 1 power stream passes through the element 3 is transmitted to the connecting element 6, the connecting element 6 power flow is divided, and the first part passes through the carrier frame 2 to the base plate 1, while simultaneously the second part passes through the conical ring 9 in a deformable pipe 5 and thence to the main plate 1. When this second part exceeds held by the transfer drum efforts through a deformable tube 5 effect on pre-determined or, respectively, set size, then there is plastic deformation of the deformable tube 5 with simultaneous extension of the cross-section, with at least a portion transmitted from the formed flange shock p is the ITA 11 to the base plate 1 energy is converted into heat or accordingly, the work of deformation and thereby extinguished. When triggered, shockproof device 100 is a relative displacement between the primary plate 1 and is made in the form of a drum flange plate 11, and the element 3 is transmitted together with the conical ring 9 is moved in a deformable tube 5.

Force operation and power level shockproof device 100 can be adjusted by the degree of prior deformation and due to the thickness of the deformable wall of the pipe 5. It is significant that after operation of the shock absorbing device 100 must be replaced only deformable pipe 5, while the remaining parts of the shock absorbing device 100 can again be applied.

In addition, it is necessary to underline the dual function performed by the connecting element 6. On the one hand, the connecting member 6 is, as mentioned above, for receiving already extended end zone deformable pipe 5 and sprays it through the carrier frame 2 to the base plate 1. On the other hand, as shown in figure 2, 5 and 8, the connecting member 6 has a thrust surface 6b, which when triggered, shockproof device 100 is sent to the external surface of the element 3 is transmitted and thereby the relative movement of the element is transmitted to the deformable tube 5.

On Fig.9-12 p is the cauldron of the fourth embodiment of a shock absorbing device 100 according to the invention. In particular, in figures 9 and 10 show a fourth embodiment of a shock absorbing device 100 in isometric projection. Figure 11 shows the preferred application is shown in figures 9 and 10 shockproof device 100, while on Fig shows a lateral incision is used on 11 shockproof device 100.

The fourth embodiment of a shock absorbing device 100 according to the invention is structurally comparable with the above options perform. However, in contrast to, for example, from the third option execute the main plate 1, which are connected to the supporting frame 2 by means of screws 20, are not made in the form of a flange, which shockproof device 100 may be connected, for example, with the body of the car or in front of him in a constructive element. Instead, in the fourth embodiment, in the transition zone between the carrier frame 2 and element 3 of the power transmission includes a flange 21. This design allows you to apply a shockproof device 100 in the form of a module and can be integrated in the crosspiece 101. This is shown at 11 and 12.

In figure 11 shows an embodiment in the form of module shockproof device 100 can be secured through is made in the form of a drum flange plate 11 on the supporting structure, while made in the form of Kruglov the pipe section carrying frame 2 shockproof device 100 is integrated in passing through the front end side of the supporting structure of the cross beam 101. In particular, with shockproof device 100 is connected through the flange 21 to the cross bar 101.

On the cross beam can be located, as shown in figure 11, if necessary, for example, protection 103 from the assault, and the clutch 104. Partially integrated into the cross beam 101 and serves, for example, as a connecting element with the body of the car shockproof device 100 is used for plastic perception of energy with a constant power level in the event of a collision. This impact plate 11 shockproof device 100 mounted on (not shown) of the car body. In the case of a first collision energy is perceived reversible or irreversible protection against tension/shock attached (screwed) to the cross beam 101 clutch 104. Then in effect shockproof device 100. As in the above embodiments, execution, shockproof device 100 according to the fourth variant execution consists of a main plate 1, the support frame 2, a deformable pipe 5, element 3 is transmitted, the conical ring 9 with the clamping element 4 and the connecting element 6. Description carried out using shockproof device 100 energy absorption has already been described above with reference to figures 1-8.

However, of course possible that are made in the form of a module shockproof device is istwo 110 according to the fourth variant of the execution itself has a reversible function of the shock absorber, as is the case in anti-shock device 100 according to the second variant of execution.

On Fig shows a fifth embodiment of a shock absorbing device 100 according to the invention. In this embodiment, the applied shockproof device 100 to connect perpendicular to the end faces (not shown) of the bearing structure of the beam 101 from the front side of the carrier structure. In particular, and as shown in Fig, which shows the section shown in Fig shockproof device 100, in the fifth embodiment, in principle, be used shockproof device 100 described above with reference to figures 1 and 2.

In particular, shockproof device 100 according pig or, respectively, 14 contains the element 3 is transmitted, one end of which is shock plate 11. This impact plate 11 serves for fastening, preferably Rethimno, shockproof device 100 to the cross bar 101 (not shown) of the bearing structure. To do this, in the shock plate 11 provided corresponding through holes 17, which serve to receive screws etc.

Design and principle of operation shockproof device 100 according Fig correspond essentially to the design and principle of operation shockproof device 100 described vicepresidente to figure 2. However, in the fifth embodiment, the shockproof device 100 is partially integrated into the cross beam 101. In particular, the transverse beam 101 has a recess 102 in which is placed a bearing frame shockproof device 100. On this frame 2, as in the first and second embodiment, the shock absorbing device 100, according to the invention Rethimno fixed connecting element 6 by means of a screw connection 15.

In the fifth embodiment, the shock absorbing device 100 according to the invention, the main plate 1 is made integrally in the cross beam 101. However, of course we can also perform the supporting frame 2 in the form of an integral component part of the cross beam 101.

Using shockproof device 100 according to the fifth variant execution offers a degree of protection against shock, which can be used to connect the provided across the end faces of the supporting beam structure 101 with the carrier structure, shockproof device 100 after exceeding the pre-set force of the impact is triggered, and the resulting transfer of impact energy efforts, at least partially converted into work of deformation or thermal energy and thereby extinguished. After tripping shockproof device 100 again, you need to replace only the deformable is the Ruba 5, while other constructive elements shockproof device 100 can be applied again.

On Fig shows a modification of the sixth embodiment of the fifth variant execution shockproof device 100 according to the invention described above with reference to Fig and 14. This modification corresponds, essentially, a combination of shock-proof device according to the fifth variant (see Fig and 14) with the second option (see figure 3 and 4). In particular, it is shockproof device 100, which is used to fasten the cross beam 101 on the front side (not shown) of the carrier structure, however, this connection is provided not only protection from attack, but also depreciation moderate shock. In shockproof device 100 integrated buffer unit 12, and the design and principle of operation of this buffer device, essentially comparable to that shown in figure 3 and 4 option execution.

Below is a description of a seventh variant execution shockproof device 100 according to the invention with reference to Fig, 17 and 18. At Fig shown shockproof device 100 according to the seventh option run in isometric projection. On Fig shows a lateral incision shown in Fig shockproof us the device 100. Items used in anti-shock device 100 according to a seventh variant of execution of a deformable tube 5 shown in Fig.

Shockproof device 100 according to the seventh option run in the structural and functional relationship in principle comparable with the second option implementation described above with reference to Fig.3-5. Just as in the second embodiment (see figure 3-5), shockproof device 100 according to a seventh variant of execution has an additional damping function that is realizable using the embedded element 3 is transmitted to the buffer device 12. The principle of operation of the buffer device 12 already explained above in connection with the description of the second variant of execution.

However, unlike the second option, run-resistant device according to the seventh variant execution is not provided, the carrying frame which is placed in a deformable tube 5. Instead, shockproof device 100 according to a seventh variant of execution, except for the already mentioned buffer unit 12, has only a main plate 1, the deformable tube 5, the connecting element 6, the conical ring 9, the clamping element 4, element 3 is transmitted, in which the integrated buffer unit 12, and the elements 15 of the screw connection.

Deformable pipe 5 through erway, facing (not shown) of the bearing structure of the end zone sealed with the base plate 1. The connecting element 6 through the elements 15 of the screw connection is connected with the second end area of the deformable tube 5 and has a guide surface 6b, which when triggered, shockproof device 100 is sent to the external surface of the element 3 is transmitted and thus the relative moving element 3 is transmitted to the deformable tube 5. The clamping element 4 serves for receiving the conical ring 9. By tightening the coupling element 6 through the elements 15 a screw connection with a deformable pipe 5 connecting element 6 presses on the clamping element 4. Thus, the clamping element 4 through the conical ring 9 is tightened with a deformable pipe 5. As mentioned above, when triggered, shockproof device 100 element 3 is transmitted is routed along the guide surface 6b of the connecting element 6 and transmits the force to the clamping element 4.

The interaction of the individual structural elements, as well as the principle of the shockproof device is comparable with options for execution as described above. In particular, in the seventh embodiment can also regulate the actuation force and the power level of anti-shock device 100 due to the advanced degree is satisfactory deformation and thickness of the deformable wall of the pipe 5. After tripping shockproof device 100 need to replace only the deformable tube 5 if necessary, with the main plate 1. The rest shockproof device 100 can be applied again.

The invention is not limited to the shown on the drawings variants of execution, and other possible combination of all the individual characteristics described above.
