Abstract

The invention relates to roadless vehicles and can be used in the construction of automobile trains. The purpose of the invention is to improve performance by increasing the reliability of the coupling of the tractor and the semi-trailer. The road train consists of a gacha and a semi-trailer. The semi-trailer contains a pin 6, made of two semi-cylinders that can move one relative to the other in the transverse plane of the vehicle, a support circle 8 is located on the t-drip, in which at least two inclined to the vertical holes 11 are made. . On the bearing circle 8 there is a lever that actuates the pushers 15. The supporting circle 8 contains an annular recess under the head of a pin 6. 5 Il.

Description

The invention relates to roadless vehicles and can be used in the construction of automobile trains.

The purpose of the invention is to improve performance by increasing the reliability of the coupling of the gacha and the semi-trailer.

FIG. 1 shows a road train, side view; in fig. 2 is a view A of FIG. 1 when disconnecting the gacha of the semitrailer; in fig. 3, view B in FIG. 2 in a state of adhesion to the condition; in fig. 4 - section bb in FIG. 2; FIG. 5 is a cross section of FIG. one.

The semi-trailer contains a frame 1 on which the body 2 and the supporting device 3 are mounted. In the front part of the frame 1, the supporting sheet 4 is rigidly attached to the latter, in which the guides 5 are made with pin half-movable half-cylinders 6 unclamped by a flat spring 7. Curtain shaft 6 interacts with the saddle device 8. fixed on

chassis 9 car -t gacha. The saddle device - 8 has a circular groove 10. in which the king pin 6 enters and two holes 11 inclined to the vertical with movable bodies 12 rolling in them. In the saddle unit 8, there are also horizontal holes 13 with movable spring-loaded compression springs 14 arranged by pushers 15 connected by a system of levers 16c with a control handle 17 which is provided with a lock 18 for its locking.

The trailer works as follows.

For coupling the semi-trailer and t gacha using the support device 3, install the trailer so that its supporting sheet 4 is about 15-20 mm higher above the horizontal surface of the saddle device 8 cars gacha and is fed backward along the arrow C (see Fig. 1). Such a move t gacha contributes to the entry of the pin 6 in space.

the saddle device (see Fig. 5). As soon as the half-cylinders of the pivot bolts come into contact with the seat device 8, they will move towards each other in the guides 5 along the arrows D and compress the flat spring 7, thereby forming a rod, as it were, which, acting on the rolling bodies 12, will move them up in the direction of arrow M and freely enter the space of the circular groove 10. Entrance of the pivot 6 into this groove will allow the half-cylinders of the pivot 6 along the arrows O to disperse under the action of the compressed spring 7 and take them into position shown in FIG. 3, with the rolling bodies 12 moving under their own weight in the direction opposite to the arrows M, and occupying the initial position shown in FIG. 3 and 5. After this, by well-known methods, the support device 3 is moved along the arrow P, which facilitates the descent of the support sheet 4 (together with the semi-trailer) to the saddle device 8, as shown in FIG. 3, while the rolling bodies 12 are not can move along the arrows M, since their movement is limited to the support sheet 4. In this case, the lower bodies 12 rolling holes 11 prevent the pin from the groove 10 from escaping even if both halves of the pin b are compressed, as if fixing its movement. Semi trailer ready to go. To uncouple the truck, the supporting device 3 lifts the semi-trailer above the road level so that the supporting sheet 4 moves away from the saddle device 8 by 15-20 mm and, removing the handle 17 from the clamp 18, rotates the latter in the direction of arrow T (see Fig. 5 ), which allows the pushers 15 to move along the arrows N and compress the half-cylinders of the pivot 6. After that, move the throttle in the direction opposite to the arrow C and the pin 6, squeezing the rolling bodies 12 along the arrows M, go out of the groove 10, and therefore, disconnect from the saddle unit 8. The link of the unit is occupied The position shown in FIG. 1. Then the handle 17 is returned to its original position and the pushers 15 under the action of the springs 14 occupy the position shown in FIG. 5. Handle 17 is secured with latch 18, and the belt is transported to its destination.
