The present invention relates to the field of trackless vehicles and can be used in the construction of road semi-trailers.

Known in combination AS the USSR №1139655, consisting of the towing vehicle and semitrailer whose trolley mounted for movement along the longitudinal axis of its frame. A significant drawback of this combination is that in emergency situations on the road when cars are coming with a significantly high speed and outside the train, catching up with him, especially at night, facing aft part of the trailer. When this shock from the car is so significant that the safety bar, located in the aft part of the frame of the trailer is destroyed and the car is under the frame and body of the trailer. This entry entails cut the upper part of the body of the car, and its people instantly die, and components and parts of the rear of the trailer in the end can not be reversed.

Also known combination in the patent RU 2240249 C1 consisting of the towing vehicle and semitrailer equipped movable in its longitudinal plane and spring relative to its frame. At the same time, the aft of the trailer is made inclined in the direction of the car, pull the and and related to its supporting sheet with base plate of the bracket, rigidly mounted on the frame of the trailer. Despite its efficiency in emergency situations, when overtaking a road train car is able to accommodate under the trailer due to its vertical movement, movement of the trolley along the longitudinal axis of the trailer, it has a significant disadvantage in that the springs are installed on the trailer, having a linear characteristic when the elastic pressure, do not allow damping of shock loads when describing the above situation, for example, devices having a nonlinear characteristic.

Therefore, the aim of the invention is the provision of a damping impact load at the time of collision of the car with the trailer.

This objective is achieved in that on the frame of the trailer in the space between the rods and parallel to them articulated set the body of the cylinder, the piston of which consists of two spring-loaded relative to each other halves and is rigidly connected by its piston rod cart frame, while in the case of the hydraulic cylinder in its longitudinal plane in newportnews cavity is made radially spaced end-to-end channels having different length cylinder diameter and linked by pipeline with the passage in Corinthians is truncated cylinder in its podpornoy cavity and covered with one-half of the above-mentioned piston in all modes of motion, braking and quiescence trains, with the possibility of opening under the action of shock loads on the safety bar of a truck.

In the drawings figure 1 shows a General view of a heavy-duty trailer side, figure 2 is the same view only at the moment of collision with him of the car, figure 3 is a transverse section through AA of the semi-trailer, figure 4 - part of the integration of the parts of the frame and semitrailer truck with each other in a perspective view and figure 5 - location of housing of the hydraulic cylinder in the longitudinal plane of the frame of the trailer in the plan.

Heavy-duty rig consists of a truck tractor with 1 semitrailer unit 2, on which is placed a frame 3 trailer 4. In the back of the frame 3 is the reference sheet 5 in contact with the support plate 6, which by means of finger 7 pivotally mounted on the bracket 8 of the bogie frame 9. On the frame of the trolley 9 is rigidly fixed to the safety beam 10, and the bracket 8, as hard-coded rods 11 with compression springs 12 which are in contact with the surface of the bracket 8 and napraviteley 13, rigidly fixed on the frame 3 of the trailer 4. On the frame 3 by means of the hinge 14 has a housing of the hydraulic cylinder 15 and the inside is movably piston consisting of two halves 16 and 17, spring-loaded relative to each other by the compression spring 18. Half 17 of the piston attached to the rod 19 hydrotrend is a, and the other end thereof rigidly attached to the bracket 8 of the bogie frame 9. In the case of the hydraulic cylinder 15 in its longitudinal plane in newportnews cavity is made radially spaced through the channels 20, which are connected to common line 22 with the channel 21, is made in the case of the hydraulic cylinder 15 in his podpornoy cavity. On the frame 3 of the semi-trailer has a limiter 23 trolley 9 and with safety beam 10 is in contact passenger car 24.

Works heavy-duty articulated in the following way. In the process of its movement in the direction of arrow b (see figure 1) trailer 4 is in position, when the carriage 9 is located in the rightmost position and the base plate 6 rested his face into the bracket 23 of the frame 3. Because the process is non-stationary and because of a number of related causes, such as uneven actuation of the brake pads of the towing vehicle 1 and the trailer 4, and during movement of the train downhill, the possible longitudinal movement of the semitrailer 4 relative to the towing vehicle 1 in the longitudinal plane of motion. However, this cannot happen because the stiffness of the springs 12 and 18 are selected in such a way that the forces occurring for the reasons described above, will not be able to move the bayonet piston 19, and therefore half 17 of the piston in the direction of the arrow C (see figure 5). At the same time, the EU and the slight deformation of the springs 12 and 18 and will happen half 17 of the piston of the hydraulic cylinder 15 will not be able to open a channel 21 (figure 5 it is seen that it is blocked by the half of the piston 17), and therefore the working fluid will not receive current through the pipeline 21 of newportnews cavity in podporchennuyu cavity in the direction of arrow D. Consequently, the translational movement of the trolley 9 for any possible changes in the mode of movement of trains is excluded. When the car 24 for a number of reasons (the driver fell asleep, fell asleep, lost control, trailer braked and so on) at a considerable speed caught up with the train and hit the safety beam 10 truck 9 (see figure 2), the last with acceleration begins to move in the direction of the arrow In, clawing across the support plate 6 plate 5 of the frame 3 trailer 4 and elastically deforms the spring 12 and 18. Under the action of such shock loads N, attached to the rod 19 of the hydraulic cylinder, the latter is passed half of the piston 17 and he, moving in this direction, compresses the compression spring 18, thus opening the channel 21. At this time, the other half 16 of the piston at some point in time is fixed due to, firstly, nsimemory of the working fluid in newportnews part of the cylinder, and secondly, even cover half 17 of the piston channel 21. As soon as the channel 21 are opened, the working fluid through the channels 20 (drawing them is provided with three different diameters, however, in practice, there may be much more) will begin to flow into podporchennuyu cylinder chamber in the direction of arrow D. as the action of the shock load N occurs in a short period of time, the flow rate of the liquid flowing through the channels 20 and 21 at this point, significant. As the movement of the halves 16 and 17 of the piston in the direction of movement of the train in direction of the arrow B, is consistent with the overlap of the first right channel 20 having the largest diameter, then the next channel 20 having a smaller diameter, and the last channel 20 having a smaller diameter, by reducing the liquid flow in the direction of arrow D is smooth damping of shock loads n Simultaneously by performing the back of the frame 3 trailer 4 inclined when moving the cart / 9 occurs simultaneously and the angular rotation of the semi-trailer 4 by the arrow G by overcoming the force of its own weight of his acting the arrow E. This movement of the semitrailer 4 further allows passenger car 24 to flow freely under his body as shown in figure 2, and thereby to prevent deformation of the roof, and this in turn creates the conditions for prevention of fatal injury to people in the past. After investigating the accident, the train is moved by the arrow In all the above details C the NIMA original position, such as that shown in figure 1 and figure 5.

Feasibility advantage of the proposed technical solution is obvious, as it will allow, first, the effective damping of shock loads arising from the collision of a passenger car with trailer, secondly, to reduce the probability of death of people in the car, and, thirdly, to avoid damage to parts and components of the semi-trailer at the intersection of their catching up with the articulated vehicle. All of this ultimately will improve the safety and reliability of the trains.

Heavy-duty combination consisting of the towing vehicle with a fifth wheel device, interacting with a semi-trailer equipped movable in its longitudinal plane of the truck is rigidly attached to its frame safety beam in contact with rods through the springs to the frame of the semitrailer, characterized in that on the frame of the trailer in the space between the rods and parallel to them articulated set the body of the cylinder, the piston of which consists of two spring-loaded relative to each other halves and is rigidly connected by its piston rod cart frame, while in the case of the hydraulic cylinder in its longitudinal plane in newportnews cavity is made radially spaced end-to-end channels having different length of hydrocil the echoes diameter and linked by pipeline with the channel, made in the housing of the hydraulic cylinder in its podpornoy cavity and covered with one-half of the above-mentioned piston in all modes of motion, braking and quiescence combination with the possibility of opening under the action of shock loads on the safety bar of a truck.
