DRAW-BUFFING GEAR TO BE COUPLED TO CENTRAL BUFFER ROD FOR RAIL VEHICLES Russian patent published in 2010 - IPC B61G9/04 B61G9/22 B61D15/06 

FIELD: transport.

SUBSTANCE: draw-buffing gear (100) is flange mounted to carriage frame and supports the coupling rod to coupling head by means of a hinge, and it transmits pressure forces in direction (5) of pressure through pre-stressed energy absorbing system (9), and in traction direction (6) it transmits traction forces through energy absorbing system (11). Multi-layered energy absorbing system and energy absorbing system are located in serried inside housing (10). One or both energy absorbing systems are equipped with non-reversible deformable element (23) in the form of a tube (29). In pressure direction, pressure plate (8) is borne against the energy absorbing system located from pressure side with reversible energy absorbing elements through inner cover (15) to inner housing (16), which through stop (17) is borne against non-reversible energy absorbing elements.

EFFECT: damping of longitudinal vibrations during movement and free-of-play support of attachment of the coupling rod with decrease of jerks and haulbacks during movement.
