The present invention relates to the field of trackless vehicles and can be used in designs of various trains.

A known design of the support-coupling devices of motor trains, consisting of cars, trucks and trailers. For example, in the book Min. Hitch cars and trucks. Design, theory and calculation. - M.-L.: the motor cycle", 1961, on p.49-51, Fig and 42 shown and described anchor hitch locking hitch pivot, used cars-trucks domestic production, such as GA-P, ZIL-N, MAZ-200V and others. The design of such devices is a (see Fig of the same book) anchor plate by means of bolts fastened to the frame of the towing vehicle. Communication support plate with a saddle carried out with the use of the flexibility mechanism, which consists of two hinges. At the saddle, made the hole mating with a longitudinal groove designed for passage of the king pin of the trailer when coupling or rescape links trains. In the saddle placed Rethimno coupling mechanism consisting of grippers in contact with the bolt, and locking their castle. The pins are rigidly mounted on the supporting sheet of the ledge of the frame of the trailer (see Fig of the same book), which is provided with a support rack with the drive mechanism intended is to install a trailer in such a position, as shown in Fig. A significant drawback of such a device is, first, the need to use manual labor in the actuator locking device, which is very unsafe, because the person is in the area of coupling or rascepa links trains, is located in a hazardous area, and, secondly, the refusal of the castle in the movement of trains can lead to samoreau him with dire consequences and even death, are at this time on the road.

It is also known reference hitch trailer, consisting of a fifth wheel of a truck tractor MAZ-5429 and semitrailer MAZ-9389 shown in the drawings, Brief book car guide. - 10th ed., revised and enlarged extra - M.: Transport, 1983 on p.81 and 91. The construction of the support-coupling devices such trains are generally similar to the above, and therefore the limitations of their own kind.

Therefore, the aim of the invention is the elimination of manual labor in the coupling and rescape car train consisting of cars, trucks and trailers.

This objective is achieved in that the hole of the saddle is made oval in it, with the possibility of angular rotation, placed oval slotted elastic sleeve with a vertically arranged groove, the size of which width is larger than the largest diameter of the bolt, and is provided at its upper tor the e teeth triangular, when this pin on the supporting sheet of the ledge of the frame of the trailer is mounted for rotation about the longitudinal axis of its symmetry, with one hand on it fixed thrust washer on the end surfaces of which are also cut these shapes of the teeth, and the other has a bevel gear interconnected with the response that is installed on the shaft, provided with a cylindrical gear that interacts with a toothed rack rigidly attached to one of the support legs of the semi-trailer.

Figure 1 shows a General side view of the anchor hitch, figure 2 is a top view of the saddle saddle device with a pulling part of his parts and figure 3 - elastic sleeve seat in a perspective view.

Anchor hitch trailer represents the base plate 1 fixed on the frame 2 of the tractor vehicle (the latter not shown). The base plate 1 by means of the hinge 3 is connected to the seat 4, which is made oval hole 5 with a built-in, oval slotted elastic sleeve 6, provided with teeth 7. In the oval elastic sleeve 7 is pin 8, provided with a collar 9 and the cylindrical portion 10, and is rigidly fixed thrust washer 11, is also provided with teeth 7. The bolt 8 is rotatably mounted in the bearing 12, is placed in the reference sheet 13 of the frame 14 of the semi-trailer semi-trailer not shown) and provided with a bevel wheel 15, interconnected with the bevel gear 16 fixed on the shaft 17, mounted in the bearings 18. On the shaft 17 is also fixed cylindrical gear 19, which interacts with a toothed rack 20, which by means of a bracket 21 fixed to the pedestal 22 of the support device of the trailer (the supporting device of the semi-trailer is also in General not shown).

Works reference hitch trailer as follows. For the production of coupling of the towing vehicle and the trailer (in the drawings, they are not shown), when the trailer is installed on the supporting device and its supporting wheels are on the ground (the position of the trailer is well known in the art, and it can be seen in the figures presented in the analogue and the prototype), the pin 8 may take a different height position relative to the seat 4, for example, such as that shown in figure 1. This is achieved by the fact that the vehicle serves back under the trailer on the arrow C. After that by means of the lifting mechanism support stands 22 (in the drawings, it is not shown), which may be mechanical, hydraulic, etc., move them in the direction of arrow C, thereby providing a draft of the semi-trailer on the arrow D on the saddle 4. As support 22 moves in direction of the arrow With respect to the frame 14 of the trailer, subcutaneo 20 rotates the bevel gear 19, and with it, the rotating torque is transmitted to the shaft 17, which is a bevel gear 16 and the bevel wheel 15 rotates the bolt 8, for example, by the arrow E. This rotation is constantly up until the thrust washer 11 his teeth 7 will not come into contact with the response made to split oval elastic sleeve 6. Under the action of the torque produced by the bolt 8, slotted oval elastic sleeve 6 also receives the angular rotation in the direction of arrow E, and as she turned in the oval hole 5 of the saddle 4, the gap δmade it decreases, and the last covers the cylindrical portion 10 of the pin 8, thereby locking the collar 9 in the saddle 4 and thereby eliminating, when possible vertical movement of the trailer from uneven roads, rescap links trains. Then move the arrow With the support legs 22 stop, and the train is ready to move. When uncoupling the trailer in the desired location, provided for unloading or storage, the support rack 22 is moved in the direction opposite to the arrow C. Such movement will provide, just as described above, the angular rotation of the pin 8 in the direction opposite to the arrow E, and then split oval elastic sleeve 6 is rotated in the direction opposite to the arrow E, and as soon as it will occupy the position shown in figure 2, cilindri the definition part 10 and the shoulder 9 of the pin 8 are released and the trailer to its supporting sheet 13 moves away from the seat 4, moving in the direction opposite to the arrow D. the following describes the processes rassau and coupling links trains can be repeated.

Feasibility advantage of the proposed technical solutions in comparison with the known obvious, since it aims at automating the process of coupling and rascepa links trailer with ensuring reliable connection of the towing vehicle and semi-trailer operating conditions.

Anchor hitch trailer, consisting of a seat with a vertically arranged opening, pivotally mounted on the frame of the towing vehicle and interconnected with the kingpin of the semitrailer mounted on the supporting sheet of the ledge of his frame and carrying the support rack with the drive mechanism, wherein the seat hole made oval and with the possibility of angular rotation is hosted oval slotted elastic sleeve with a vertically arranged groove, the size of which width is larger than the largest diameter of the bolt, and is provided at its upper end, the teeth triangular, with the pin on the support sheet of the ledge of the frame of the semitrailer mounted with the possibility of rotation about the longitudinal axis of its symmetry, with one hand on it fixed thrust washer on the end surfaces of which are also cut from Omanthai the shape of teeth, and on the other there is a bevel gear interconnected with the response that is installed on the shaft, provided with a cylindrical gear that interacts with a toothed rack rigidly attached to one of the support legs of the semi-trailer.
