TOWING DEVICE AND DEFORMABLE TUBE IN COUPLING FOR RAILWAY CARS Russian patent published in 2009 - IPC B61G5/02 B61G9/04 B61G11/16 

FIELD: railway transport.

SUBSTANCE: invention is related to the field of railway transport, namely to towing devices intended for couplings of rolling stock. Towing device comprises rod, on the back end of which finger is available. Finger protrudes in axial direction via through hole in plate. Both sides of plate cover spring shock-absorbing elements that always try to support finger in initial position relative to plate and under action of which finger and rod may move in axial direction. Plate is located in holder, which has cone and is inserted into deformable tube. Wide front part of tube via journal passes into narrower back part that is deformed as holder penetrates in it. Deformable tube has cylindrical shape as a whole and comprises back part that via journal narrowing to cone passes into wider front part, to which flange is connected to fix deformable tube in frame or in chassis of transport facility unit. Inside wide front part there is facility for fixation of clamping ring.

EFFECT: possibility is achieved to absorb and suppress large amount of energy that is produced in case of collisions, without specific protection facilities against collision and simplified design of device.
