SHOCK-TRACTION EQUIPMENT OF ROLLING STOCK Russian patent published in 2018 - IPC B61G9/00 

FIELD: machine building.

SUBSTANCE: in the proposed device comprising a head of the coupling, an absorbing apparatus, a device for transmitting forces to the frame of a stock rolling unit and a crash device with a tubular crash element, one of the crash element ends is charged into a block die mounted in the opening of the device for transmitting forces to the frame of a rolling stock unit, preferably in the form of a plate with a hole, with the formation of a two-moving kinematic pair between them, and the absorbing apparatus is installed between the coupling head and the crash element second end. Device is also provided with elements preventing the coupling from rotating around the crash element axis, preferably in the form of grooves on the block die outer and inner surfaces.

EFFECT: simplified design.
