FIELD OF THE INVENTION The invention relates to railway rolling stock, mainly to the auto-rail device of freight cars.

The autotarget devices of freight cars are known, consisting of an automatic coupler, an absorbing device, a traction yoke, an anvil plate and a front and rear stop. However, it is not possible to obtain a stroke of an absorbing device of various sizes under the action of compressive and tensile forces. This is usually eliminated by reducing the strength of the elements of the auto-price device and the car frame and the introduction of additional details.

A special feature of the described automatic coupling is that the housing of the absorbing device is equipped with protrusions, which, during operation, pass through the corresponding grooves in the thrust plate and interact with the front stop.

This makes it possible to limit the movement of the automatic coupler 1 under the action of tensile forces.

FIG. 1 shows the proposed coupler in two projections; in fig. 2 - fixed plate with grooves.

The coupler consists of a coupler 1, an absorbing device 2, a traction yoke 3, a support plate 4, a front stop 5 and a rear stop 6. The housing of the absorbing device 2 is provided with a projection, and in the support plate 4 there are corresponding slots b .

Under the action of pulling force, the protrusions a of the absorbing device 2 pass through the grooves of the short plate 4 and, moving by a set amount of the stroke of the device, abut against the front stop 5, providing a definite movement of the automatic coupling.

Subject and d on and e and

The autocoupling device of the freight car, the state of the coupler, the absorbing device, the traction yoke of the thrust plate, the front and rear stops, characterized in that, in order to limit the peremetsennnogo coupler under the action of tsvyh efforts, in the corresponding grooves made in the thrust plate, and interacting with the front stop.
