METHOD OF AND DEVICE FOR REMOVING IMPACT ENERGY Russian patent published in 2003 - IPC

FIELD: railway transport. SUBSTANCE: invention relates to method and device for removing impact energy, particularly in automatic couplers of rail vehicles and design of devices for removing impact energy and method of realization of impact energy removal. impact energy, according to invention, is removed by overcoming resistance of flow in liquid compressible and preliminarily compressed elastomer, removal of impact energy is carried out in several steps. Device for removing impact energy includes elastomer shock absorber in working cylinder of which two rods are inserted. Rods differ in diameters. Smaller diameter rod adjoins by its end to bottom of device housing, and bottom of elastomer shock absorber thrusts against shook plate. EFFECT: provision of removal of impact energy under different operating conditions, with damping of high and low energy impacts. 3 cl, 2 dwg +AF8-
