Abstract

FIELD: rail transport. The purpose of the invention is to increase reliability. In the shock interaction mode, the hook 13 is deflected and then hooked to the hook of another vehicle. The force at collision is sensed by the sleeve 3 and through the elastic element and the traction element 7 is transmitted to the vehicle frame. In the thrust mode, the force from the hook I3 is transmitted to the thrust element 7, which in turn, through the elastic element 9 and the sleeve 3, transmits the force to the vehicle frame. 3 il. iL 20 J7JS // / 6 g 16 i (L 21 with 00 4 ;: 4; SL 4

Description

FIG. 2

This invention relates to rail vehicles, in particular, to shock devices.

The purpose of the invention is to increase reliability.

In Fig.1 schematically shows the proposed device, side view; figure 2 - section aa in figure 1; on fig.Z - view B in figure 1.

The shock traction device consists of a guide cover 1 with an emphasis 2, a cone-shaped buffer sleeve 3 with projections 4 and 5, and a buffer 6, a cone-shaped traction element 7 with a protrusion 8. A cone-shaped rubber-metal elastic is installed between the traction element 7 and the buffer sleeve 3 element 9 with an inner metal ring IO and an outer metal ring 11. The plates 12 are welded to the front part of the traction element 7, between which is installed a hook 13 fixed by a spring 14 and a finger 15. A switch 16 is attached to the hook 13 m 17, consisting of two tons of g 18 and 19, interconnected by a hinge 20, and passing through the window 21 of the buffer sleeve 3.

The impact device works as follows.

When two trolleys collide, the hooks 13, interacting with each other, overcome the resistance of the spring 14 and engage with each other. When the car moves, the force through the hook 13, the finger 15, the plates 12 is transferred to the traction element 7, which protrusions 8 abut against the inner metal ring 10 of the damper, and the outer metal ring 11 rests against the protrusion 4 of the buffer sleeve 3. Then through the protrusion 5, the buffer sleeve 3, the force is transmitted to the protrusion 2 of the guide clamp

1, which is rigidly fixed to the frame of the trolley. In this case, the elastic element

9 works in compression and shear.

I

When working on the buffer, moving the switch 16 (in the direction of the arrow) leads the stop 17 through the window 21 and, turning the switch 16 by 90 °, fix the hook 13, as the stop 17 abuts against the buffer sleeve 3 from the outside. When working on the buffer, the force through the buffer 6 is transferred to the buffer sleeve 3, which protrusion 4 abuts against the outer metal ring 11 of the elastic element 9, and the inner metal ring 10 of the elastic element 9 abuts against the ledge 8 of the traction element 7, which trolleys. When this rubber-metal elastic element 9 also works in compression and shear.
