Trolley vehicles

 

The invention relates to consistently associated rigid swivel axis with the Central axis of rotation. The cart contains at least two hard axis (la-lb), which are connected by a rocking lever (10), which can be made in the form of springs. The swinging arm (10) has the ability hinge rotation at its mid-point (14b), so that it can move in its longitudinal direction as a result of movements of the steering mechanism. The swinging arm (10) is mainly connected with the shaft (1b) trucks, which makes the smallest rotation, by means of hinge (13b) of the holder (13), so the specified axis (1b) truck determines the longitudinal movement of the swinging arm (10). The swinging arm (10) is connected also with other axes (1A) trucks, which make more rotation, by means of suspension rods (8). Preferably necessary for the greatest possible length of the suspension thrust (8) she pinned under axis (1A) of the truck. In the suspension rod (8) has a smaller slope with the longitudinal movement of the tilting arm (10). The proposed solution is aimed at reducing loads of the suspension and the steering. 11 C.p. f-crystals, 19 ill.

Currently the TV, such as vehicles for mining, and the construction of the trolley includes at least two interconnected rigid axis, which form a cart, at least some of these axes belonging to the truck made with the possibility of rotation when the vehicle is controlled in relation to the vertical axis of rotation located between the ends of the axes are controlled with respect to the frame of the vehicle, connecting owned the truck axis, and the construction of the trolley includes a swinging lever (rocker), which is installed with the possibility of rotation about the transverse axis of the vehicle between its ends and moves in the longitudinal direction of the vehicle in the traffic management axles of a bogie by means of the steering mechanism.

The hard axis is usually used on vehicles that are designed for special heavy vehicles such as heavy vehicles and machinery, transport vehicles for mining, etc. Such vehicles mainly supply the hard axes, as loads are heavy. In addition, the hard axis is economically profitable. Usually in heavy vehicles has more than two axes and the axis is connected with the construction of the trolley using a variety of levers and springs that allows to distribute the load between the different axes. When designing a special heavy vehicle must take into account the effect of uneven loading of the vehicle and uneven surface motion, which affects the load axis and the behaviour of the vehicle. Moreover, as heavy vehicles tend to have larger external dimensions, i.e. they are long and wide, to facilitate driving is usually necessary to be able to control multiple axes. The turning radius of the vehicle can be significantly reduced if all axes are made to rotate when turning the vehicle.

The hard axis, is made to rotate when turning the vehicle, usually connected to each other in the design of the truck using the balancing lever, usually with the aid of the tilting lever engaged pivotally rotate (rotate on its axis) between the ends of the truck. Because wheels with various parties transportirovaniia axis must have the ability to rotate to different angles depending on their position in the longitudinal direction of the vehicle, so successive wheels can move in the same circle of rotation, in the previously known solutions connecting the axis of the swinging arm made with the possibility of movement in the longitudinal direction of the vehicle due to its hinge pin and rotate on the axis of rotation, and due to its connections with other axes using different suspension rods and joints. Also known and these decisions, in which the swinging arm is fixed and does rotate around its axis on the frame, causing the hinge to rotate the suspended rods and allows the axes to make the necessary motion by established between the axes of the steering wheel and swinging arm.

A disadvantage of the known solution is that it requires considerable space to the levers could make the turn, required when driving the vehicle. Another problem stems from the fact that when driving the frame of the vehicle goes up and down, which requires considerable effort on the part of the steering mechanism. Because the elements of the steering mechanism must lift the weight of the vehicle and transported them to load when turning the vehicle, the wheel suspension cell battery (included) and the design of the truck, intended for special heavy vehicles, such as vehicles for mining that removes the disadvantages of the previously known devices.

The construction of the trolley in accordance with the present invention is characterized by the fact that the swinging lever mounted between the axles, which should be related to each other, and the swinging lever performs a rotation about its axis in the hinge between its ends so that it can rotate relative to the frame, with the specified hinge is arranged to move in the longitudinal direction of the frame so that it follows the movements of the tilting lever in the longitudinal direction of the vehicle caused by control of the axes by means of the steering mechanism and the first end of the rocking lever is connected with the first axis by means of the pendant pull, and the first end of the first outboard thrust does pivotally rotate relative to the first end of the tilting lever when the second end to the first axis, the second end of the tilting lever makes a turning of the hinge on the second axis that is installed to rotate in the specified joint, and this axis defines the offset of tajnosti move mainly in a horizontal direction in the vehicle control using the steering mechanism.

The basic idea of the present invention is that two or more consecutive hard axis of the joint in the construction of the trolley by means of a swinging arm or more of the tilting levers, depending on the number of axles. Bogie axle is connected with a rocking lever by means of the pendant rods or the respective holders, and a swinging arm configured to pivotally rotate on the frame between its ends. Another significant feature of the present invention is that the swinging arm is arranged to move in the longitudinal direction of the vehicle, which is required for driving, so that the pivot point (hinge), which is located between its ends and about which the swinging lever does swing, makes a move in the longitudinal direction of the vehicle. The degree of displacement of the rocking lever in the longitudinal direction of the vehicle is determined largely by axle truck, which is rotated in the least degree. The swinging lever performs a rotation on this axis in the hinge, which is movable in the up and down direction, but transmits motion control axis for swinging rerolling move in accordance with movements of the control of the steering mechanism. The main idea of the preferential variant of the present invention is that the swinging lever does pivotally rotate relative to the free end of the support bracket engaged pivotally rotate relative to the frame. The main idea of the other predominant variant of the present invention is that the swinging lever between the axles of a vehicle commits the hinge rotation at least relative to the outer (far) below the axis, i.e. the axis that makes the greatest turn, using, for example, curve-shaped suspension traction, and makes the hinge rotation about the other axis with the hinge. The main idea of the third preferential variant of the present invention is that on the bottom surfaces of at least some of the axes provided by the holders, the speakers relative to the axis down. The holder and, therefore, making it swivel rotation outboard thrust farther removed from the longitudinal center of the vehicle. This build allows you to compensate for different degrees of inclination of the suspension rods due to different angles of rotation. The main idea of the fourth preemphasized hard axes, connected together on both sides of the vehicle by means of a longitudinal balancing levers. Thus, a lever mechanism to evenly distribute the load applied to the trucks and their axes at various the goods transported and the situations of the vehicle. Moreover, the lever mechanisms on both sides of the frame can be connected with the cross of the balancing lever or by using other devices that also allow rotational movement between the trucks.

The advantage of the present invention is that the control axes does not result in substantial vertical movement of the frame, and therefore will be less than the load applied to the lever mechanism and the elements of the tie rod. Moreover, the device of the mechanical lever in accordance with the present invention is simple and durable, and its parameters can easily be changed by changing the stiffness of the spring, shoulder arm, hinges, etc. Another advantage is that the levers truck can be easier integrated into the design of the vehicle than in previously known solutions, which leaves more space for different socotora does hinge rotation below the axis, is that this suspension rod can be longer than in the case of hinge rotation over the axis. However, the need for space above the axis does not increase, as only part of the overhead traction protrudes above the top surface of the axis. Provided with a long suspension traction advantage lies in the fact that she bends less than shorter outboard thrust, as a result of longitudinal movement of the tilting lever, caused by the movement of the steering mechanism in its extreme positions.

Due to the presence of a long suspension traction will not be a significant vertical displacement between the ends of the tilting lever, that is, the swinging arm has a bend at its hinge rotation in the movement of the steering mechanism. Another advantage of a longer suspension traction, which has a smaller slope, lies in the fact that the force is distributed better than in the presence of suspended traction with a large slope. To a suspension traction, which has a smaller slope is applied mainly to the efforts of compression and tension, which reduces the stiffness of thrust compared to the previously used rods, and can be used for easy hanging rod with less is emnd outboard thrust with a large slope, that allows to simplify the design of levers, cylinders and other elements of the steering mechanism. Due to pivotally rotate under the axle attached to the axis torques can be absorbed without additional support brackets installed above or below the axis. The support axis may be performed using a triangular support, mainly in the middle of the axis and by means of suspension rods at its ends. Another advantage is installed between the axes of the lever mechanism in accordance with the present invention is that it allows a more even distribution between the axles of the load represented by the weight of the vehicle and transported by cargo and attached to the axles of the vehicle, which allows the use of lighter axles, springs and other components of the support and suspension axes than in the previously known solutions. Due to the proposed linkage of the load can be evenly distributed even when the vehicle is on uneven ground, with the result that all of the wheels close to the ground, the vehicle goes faster. In addition, the lever mechanism in accordance with the present invention is tion.

The present invention will be described hereinafter in more detail with reference to the accompanying drawings.

In Fig.8a-8d schematically illustrate two different four-axle vehicles, which have a three-axle truck in accordance with the present invention.

In Fig.1A shows a greatly simplified side view of the design, which is based on a truck in accordance with the present invention. You can see that as in Fig.1A or 1b, and on the other the following drawings do not show all components associated with the steering mechanism and other equipment for driving the vehicle, and for simplicity omitted at least one device associated with a power transmission, used in the steering mechanism by the hydraulic cylinders and other Additional simplification of the drawings produced to highlight elements most relevant to the present invention. Shown in the drawings, the structure contains four axis la-1d, which you can see on the side of the vehicle and which form two carts connected by means of levers, namely the front bogie 2A and a rear bogie 2b. Front and rear truck can have the same ansporting funds. Needless to say that between these carts may be differences in the stiffness of the springs and the sizes of the components, which depend, for example, from the destination of the vehicle and the weight distribution between the trucks. Axles are rigid, as their capacity (carrying capacity) is high, and the design is simple. To simplify the drawings the single wheel 3 is shown only on one side of the vehicle, however, it goes without saying that the wheels can also be doubled if it is necessary to ensure the capacity and surface friction movement. Each of the axes la-1d can forcibly rotate, that is, all the wheels of the vehicle are controlled. The rotation axis may be, for example, by hydraulic cylinders or by means of suitable actuators (not shown), which used the rod and the levers steering required to control the vehicle, as well as other elements of the steering system, United with axes and actuators. These elements produce a rotation axis, so the axis of turning of the vehicle parallel tangents to circle the chickpeas in opposite directions relative to each other, and the corresponding inner axis is also rotated in opposite directions relative to each other, but less than the external axis. Each axis is connected with the frame 5 of the vehicle by means of the triangular pillars 4, shown in Fig.1b, so that prevented the free longitudinal and transverse movement of the axle relative to the frame. The middle point of the axis can also be supported by appropriate longitudinal and lateral support brackets. The frame 5 of the vehicle mainly has two beams 5A and 5b, which are mainly parallel with a gap between them, and their cross-section has the shape of the letter Z. However, if necessary, can be used and other design of the frame and forming her profile. The triangular support 4 does hinge rotation between the frame beams on their inner surfaces, so that the triangular support allows the axles to move up and down relative to the frame, and the axis is operated by a lever mechanism that is included in the design truck. Moreover, one end of the triangular support, nearest to the axis, a hinge 6, which is connected to the middle point of the axis, and the hinge allows the em also hard axis to oscillate (swing) with respect to it in the longitudinal direction of the frame, when there is a height difference between the wheels on opposite ends of the axis, for example, due to the uneven surface of the vehicle, etc.

Thus, the proposed design has the suspension, which consists of hinges, hanging rods, swinging levers and springs, which are shown in simplified form in Fig.1C. Appropriate linkage mechanisms are provided on two sides of the frame, mostly outside of it. The front axis, that is, the first axis 1A and the second axis 1b, are connected, and the corresponding rear axle, that is, the third axis 1C and the fourth axis 1d, also connected mechanically so that the axis of the form, respectively, two carts 2A and 2b, each of which contains two managed suspended on springs axis. These trolleys are interconnected by means of the balancing lever 21, parallel to the longitudinal direction of the vehicle. In addition, linkage mechanisms, which are provided on two sides of the frame are interconnected by means of transverse balancing lever 24, described hereinafter. The first curve hanging rod 8 in the form of a sickle or letters From doing pivotally rotate the first axis 1A, that is, on the surface, at or near the longitudinal rocking lever 10 by means of a hinge 9. May provide the first spring element 11, which is primarily a set of flat springs installed between the oscillating lever 10 and the first outboard thrust 8. This design can also be formed without the mentioned spring element, for example, if the flexibility of the swing arm provides the necessary spring effect. There is no need to have sprung all vehicles to move at low speeds. Between the first outboard thrust 8 and the oscillating lever 10 includes a hinge 9, which permits the rotation axis and the movement axis in the direction of up and down. Alternatively, the hinge 7 can provide motion control axis 1A. Thus, the front end of the first swinging arm 10 is connected with the upper end of the spring element 11 mounted on the first outboard-powered 8 with the corresponding hinge 9. At the other end of the lever 10 connected to the other longitudinal rocking lever 12, which performs the rotation in the first holder 13, the established steady-axis on the top surface of the second axis 1b. In other words, the first swing lever 10 does pivotally rotate on the lower powermovie swinging the lever 10 also performs the hinge rotation on the frame between its ends by means of a first outboard thrust 14, which is installed with the possibility of hinge rotation relative to the frame. Moreover, between the support bracket 14 and the first rocking lever 10 includes a hinge 14b, which together with the hinge 14a supports the ends of a rocking lever 10, mainly, on the same height, when the swinging lever moves in the longitudinal direction of the vehicle by controlling the axes (steering mechanism). The support bracket 14 is mostly sufficient length to vertical displacement of the tilting lever, caused by horizontal movement of the upper end of the support bracket, it was probably less. Instead of rotating the support bracket pivot (hinge) of the tilting lever can move in the longitudinal direction of the vehicle due to the use of the sliding mechanism. The first swinging arm is primarily parabolic spring plate kit spring (leaf spring) or other suitable spring element which receives the load and at the same time give part of the axial loads on the other axis. The second swinging arm 12 may also be spring element of the specified kind, oglasnik way without the elasticity of the levers, and in this case, effort can be perceived by an individual (other) spring elements. In accordance with the proposed solution mainly produce uniform load distribution between the different axes of this truck and other related trucks. Consequently, a single axle, spring or supporting structure axes should not be as massive as it would be necessary in the case of a separate spring-loaded mounting to the frame of each axis, without the use of compounds in accordance with the present invention. The function and the behavior of the connection of the trolley in accordance with the present invention and associated with trucks levers in different driving situations will be more fully described with reference to Fig.6A - 6C and Fig.7.

As shown in Fig.1A-1C, the levers front and rear axles 2A, 2b are mainly the same. Thus, the fourth suspension rod 15, which also has a C-shaped form, makes the hinge rotation at the fourth axis similarly to the front of the cart. Also there may be another spring element 17 between the outboard thrust 15 and the fourth longitudinal rocking lever 16. The end of the fourth tilting lever 16, aegusa lever 18, which is fixed on the upper surface of the third axis 1C by means of the third support bracket 19. In addition, the fourth swing arm 16 is attached to the chassis using the fourth support bracket 20, which makes pivotally rotate relative to the frame in accordance with the movement of the suspension and steering.

Between the front bogie 2A and the rear carriage longitudinally relative to the frame has a counterbalancing lever 21. This lever makes pivotally rotate relative to the frame or to the set on the frame of the holder arm, and specified a counterbalancing lever passes the part attached to the front of the truck loads on the rear truck, and Vice versa. Facing the rear of the truck end of the second swinging arm 12 of the front bogie is connected to the other support bracket 22, one end of which makes pivotally rotate relative to the balancing lever 21. The third swinging lever 18 is connected similarly with the third outboard thrust 23, and the lower end of the third suspension traction connected with the other side of the balancing lever 21. The described device can be modified by use of hydraulic cylinders instead of hanging rods 22 and 23, and through this showing of the cylinder under the action of the load out of the cylinder, on the same or a different distance, there is no need to use a balancing lever 21. This solution is preferred, for example, when there is no space for installation of the balancing lever. Moreover, the cylinders provide good handling and absorb movement (absorbers are), so they can be used to improve the maneuverability of the vehicle.

It is shown in Fig.1C and 1d hinge lever mechanism has a letter designation, corresponding to the predominant type of hinges. The letter P denotes a ball joint, allowing movement with three degrees of freedom, and the letter S denotes a hinge joint is a joint that allows movement with one degree of freedom around the vertical or horizontal axis of rotation in the hinge.

In Fig.1d shows how to connect with each other are installed on different sides of the frame lever mechanisms with the help of gravity of the lever 24. The effect of this connection is particularly evident in cases where trucks do tilt in different directions relative to the longitudinal axis of the vehicle, i.e. when the trucks are fluctuations. In the Noah degree tilt. Moreover, such cross-connection prevents jerking of the vehicle when braking and accelerating. Cross-connection mainly contains transverse balancing lever 24 mounted between the frame beams 5A, 5b, and mounting rods 25A, 25b, set between the ends of the transverse balancing arm 24 and the longitudinal balancing levers 21A, 21b both lever mechanisms. Rod transmits the force applied to the lever mechanism on one side of the vehicle, a lever mechanism on the other side, and Vice versa. Transverse balancing lever and its associated rod can be replaced by other means, such as hydraulic cylinders. Such cylinders can be directly connected to the longitudinal balancing levers by means of suitable hinges, and in such a tool with the cylinders, one piston rod is pushed in one cylinder and the other at this time out of the other cylinder. If necessary, the cylinders can also be used as shock absorbers (to absorb movements).

In Fig.1E shows a side view of another embodiment of structure in accordance with the present invention. In principle this design, the first set of springs, attached to the upper end of the first outboard thrust 8 without a separate spring element. Shown by the dotted line rod 25, which actuates the transverse balancing lever, is connected with the longitudinal balancing levers 21.

Can be manufactured in various modifications shown in Fig.1A-1E lever mechanism. You can also affect the function of the lever by changing the size of its various components, for example, by changing the dimensions of the tilting levers and balancing levers, as well as changing the position of the hinge joints. If necessary, the appropriate nodes of the lever can also be provided with the relevant absorbers.

In Fig.2A shows a strongly simplified schematic side view of the connection design of the trolley in accordance with the present invention. The cart contains two controlled axes that can make in their middle part of the hinge rotation by means of the hinge 6, mounted on a triangular pole or other similar element, so that the axis can be rotated about this pivot during steering of the vehicle. Moreover, the hard axis can swing on this is here depending on the height of the wheels on opposite ends of the axis. You can see that the first axis 1A, which is advanced outward more than the second axis 1b performs rotation in a greater circle of rotation. Thus, the angle of rotationthe first axis 1A is greater than the anglethe second axis 1b. Axis 1A and 1b are combined in the cart 2A by means of the first swinging arm 10, and the first axis 1A is connected with the first end of the tilting lever 10 by means of a first outboard thrust 8. The second end of the swinging arm 10 is connected with the second axis 1b with the bracket 13, which is vertically downwards from the axis. The axis with which the swinging arm is connected only with one swivel (second axis 1b in this case) determines the largest longitudinal movement of the tilting lever during movement of the steering mechanism. It is clear that it is preferable to select the axis of the truck, which makes a smaller rotation as the axis determining the extent of longitudinal movement of the tilting lever so that movement of the levers were possibly less. The swinging lever does pivotally rotate between their ends, mostly in their mid-point, by means of hinge 14b mounted on the upper end of the support bracket 14, and a moving rich the example, when driving on uneven surfaces. The lower end of the support bracket 14 does hinge rotation in the hinge 14a provided on the frame 5, so that the support bracket can be rotated about this pivot 14a as a result of movements of the steering mechanism. In other words, the swinging lever makes the hinge rotation, so that it can move in its longitudinal direction as a result of movements of the steering mechanism. Movement of the steering mechanism basically do not change the height of the frame of the vehicle, particularly if the supporting bracket 14 is relatively long and leans slightly. In this case, change the height of the frame is insignificant in comparison with the previously known solutions. The swinging movement of the lever 10 and, consequently, the angle of rotationthe support bracket 14 is determined by the angle of rotationthe second axis. It should also be borne in mind that on the other side of the frame, i.e. on the side of the inner circle of rotation, the swinging lever moves in the opposite direction. Since the angles,rotation axes have different meanings, the levers must allow change Rasta between the nearest ends of the axes 1A and 1b more than in the situation of Fig.2b. This can be done by direct suspension traction, which makes pivotally rotate relative to the upper surface of the first axis, but in this case, the suspension thrust adversely leans in the extreme positions of the steering mechanism that creates a substantial horizontal forces. However, if you use outboard thrust, which makes the hinge rotation, under the axle, it can be made longer, so he increased the distance between the hinge 9 at the first end of the swinging lever and the hinge 7 under the axle. When this lever mechanism is also lower, which simplifies the design of the vehicle. The previously described curve outboard thrust in the sickle or letters can rotate around the axis and respectively removed from it when the swinging movement of the lever in its longitudinal direction. For this reason, use a hanging rod with a fairly wide gap R between the facing to the axis of the curved section of the suspension rod and the axis, so that there is enough space for tilting the outboard thrust. In the drawings, it is shown that this gap R is widest in one of the end positions of the control and lowest in the opposite position upravlenceskie with the present invention. The first curve hanging rod 8 with a C-shaped form, does hinge rotation in the hinge connection 7 on the bottom surface of the first axis 1A, and the joint has one degree of freedom. The upper end of the outboard thrust does hinge rotation in the hinge connection 9 at the first end of the first swinging arm 10, and the hinge has two degrees of freedom. The hinge 7 can also have two degrees of freedom, and in this case, the hinge 9 will have one degree of freedom. In any case, it is necessary to provide sufficient space for turning axis with respect to the outboard-powered. It is important that the hinges 7 and 9 allow the suspension traction to make a tilting movement of the tilting lever in its longitudinal direction, and that at least one of the hinges allow the axle to rotate relative to the swing arm, being mainly parallel to the frame of the vehicle. The other end of the tilting lever 10 does hinge rotation in the hinge 13b of the holder 13, which is mounted on the upper surface of the second axis 1b. The hinge 13b should allow the axis to move in the vertical direction and, therefore, allow to swing the swinging lever. This hinge also delgany twist between its ends to the hinge 14b on the first supporting bracket 14, so that it can be inclined relative to the horizontal axis of this hinge in the longitudinal movements of the axis. The lower end of the support bracket 14 does hinge rotation in the hinge 14a of the holder 5C mounted on the frame. As the swinging lever does pivotally rotate relative to the frame by means of two hinges 14a and 14b, it can move in the longitudinal direction of the vehicle, as it is required for the steering, so the height of its ends does not change significantly and the additional load does not occur.

In Fig.4 shows a greatly simplified side view of a truck with three rigid and steering axles. The design includes two rocking levers 10A and 10b, which can move in its longitudinal direction as a result of movements of the steering mechanism. The amount of movement of the tilting levers caused by movements of the steering mechanism, mainly is determined by the internal axis of the truck, i.e. the axis 1C, which is rotated in the least degree. One end of the inner swinging arm 10b does hinge rotation on this axis by means of the second intermediate lever 26b and the holder 13. Between the outer swinging arm 10A and the inside is and the upper end of the second outboard thrust 8b, between their ends. The two most external axis 1A and 1b are connected to the lever mechanism of the truck by means of the C-shaped suspension rods 8A and 8b, which are pivotally rotate under these axes. Hanging rod allows the first axis to turn the most, that have the largest angle of rotation and the second axis makes a greater rotation than the third axis. Moreover, one end of the intermediate lever 26b, which makes pivotally rotate relative to the holder 13 of the third axis 1C is connected to a counterbalancing lever 21, parallel to the longitudinal direction of the vehicle, using outboard thrust 22. A counterbalancing lever is mounted between this and the follow-up trucks and produces a uniform distribution of the loads between them. The first swinging arm 10A, the first intermediate lever 26a, the second swinging arm 10b and the second intermediate lever 26b is designed in such a way that they move mainly in a horizontal direction and are moved at an equal distance required depending on the angle of rotation axis 1C.

In Fig.5A shows a three-axle truck, similar to those shown in Fig.4. The dash-dotted line with two points shows the slope of the first outboard thrust in the case of eeoi outboard thrust 8A, which makes the hinge rotation in the hinge 7b on the lower surface axis, and the dash dotted line shows the slope of the C-shaped suspension thrust (thrust not shown), which makes the hinge rotation in the hinge 7C holder 27 (shown in dashed line) that can be installed on the bottom surface of the axis and goes down. In the latter case, the tilt of the outboard thrust 8A smallest, so that the proportional component of the horizontal force X applied to the lever mechanism, is less than in the other two cases, especially in comparison with the case of mounting an outboard thrust above the axis (proportional component of the horizontal force X'). In the implementation of hinge rotation below the axis does not occur a significant component of the horizontal force applied to the lever mechanism, so the levers steering mechanism and actuators can be easier than usual design. You can affect the angles of the suspension rods by providing on the lower surfaces of the axes aimed down holders 27 of the desired length, which make the hinged rotation of the lower ends of the suspension rods. It should be borne in mind that the lower is the holder, the farther is the axis from the axis of the truck 1C, which is as a result of the movement of the steering mechanism). The length of the holders may be selected so that the angle of the suspension rods is mainly constant, regardless of the position of the axis, when this is applied to the outboard thrust load is constant at a given slope. In this case, can be used hanging thrust, standard size.

In Fig.5b shows another solution, which allows the hinged rotation of the outboard thrust 8 below the axis of the truck. In accordance with this decision around the axis of the truck frame provided, which is pivotally rotated relative to the axis of the truck. It should be borne in mind that the hinge rotation below the axis of the trolley can also be implemented in another way, and form a suspension thrust can be another.

In Fig.6A shows a design with four axes, and shows how the two are related to each other carts in accordance with the present invention behave when driving on surfaces with varying terrain. It is seen that the wheel tightly against the rough surface movement, and a lever mechanism takes the load and distribute them evenly between the axles and bogies.

In Fig.6b shows the situation in which the vehicle with the design according the swinging levers in the longitudinal direction, that is, they bend only at the expense of hinge rotation between its ends.

In Fig.6C shows the behavior of a structure in accordance with the present invention overcome the rise, that is the situation, the opposite is shown in Fig.6b. From a consideration of Fig.6A-6C can be concluded that the lever mechanism does not take up much space on the axles of the truck, even with substantial movements of the axes shown in driving situations.

In Fig.7 shows a side view that shows how the behavior of the structure during vibration. You can see that the truck 2A and 2b turned in opposite directions relative to the longitudinal axis of the vehicle. Longitudinal balancing levers on opposite sides of the vehicle are also rotated in opposite directions. Note that in Fig.7 is not shown cross-connection between the lever mechanisms.

In Fig.8A shows a side view of the axle of the vehicle, with three hard axis of the joint in the truck with the help of connections in accordance with the present invention. The wheels on the first axle of the vehicle are rotated, for example, around the hinge bolts provided on the ends of the axis, but what about the tools do rotate around the same point of rotation R, as shown in Fig.8b. From consideration (Fig.8b), it follows that the front axle three-axle truck has no rotation, while the subsequent two axes make the rotation (turn). The design contains two longitudinal swinging of the lever, between which there is a counterbalancing lever that is configured to pivotally rotate relative to the Central axis. Mainly provides a counterbalancing hinge between the lever and the rocker arm, which allows the contact slip in the horizontal direction, so that the balancing lever and rocker arms can swing. Both longitudinal tilting lever is arranged to move in their longitudinal directions, as required under control of a steering mechanism. Moreover, to compensate for different angles of rotation on the outer ends of the rocking levers are provided outboard thrust, which are pivotally rotate under the most remote from the center axis. In situations that shown in Fig.8C and 8d, hard middle axle truck has no rotation, while the two outer axes have the ability to rotate. In accordance with this decision, there is no need to use the rocker arms with Cosmopolit directly relative to the frame. Optional hinged rotation of the tilting levers can be carried out using a rotary support brackets, as shown in Fig.8C dashed line.

It should be borne in mind that despite what has been described the preferred embodiment of the invention, it is clear that it specialists in this field can be amended and supplemented, which do not extend, however, beyond the scope of the following claims. Although in the description of the invention described and in the drawings is shown a rotary axis of the truck, the present invention can be applied to axes that are not turning. In this case, the movement control may be effected by control of the frame or for the account management by using articulated fingers, and in this case, the wheel can be rotated about the axis of the truck. In addition, there is no need to use rocker arms can move in the longitudinal direction of the vehicle, as they may make the hinge rotation directly, for example, with respect to the frame. Moreover, the axis of the front truck may be rotatable, while the axis of the rear of the truck can be tools in the truck with the help of a rocking lever in accordance with the present invention, when they rotate in opposite directions relative to each other, equal or different angles of rotation. In addition, the distance change due to different angles of rotation driven hard axis can be provided, for example, by means of a swinging arm, both ends of which are telescopic, and this lever allows you to increase or decrease the distance. This solution requires that the pivot point of the rocking lever to be shifted so that the shoulders of the lever kept a desirable ratio of the distances, regardless of the length change of the tilting lever. Alternatively, it is necessary to provide appropriate compensation for efforts to eliminate problems associated with the changing of the shoulders of the lever. In addition, if necessary, can be modified degrees of freedom hinge lever mechanism.
