FREIGHT CAR BOGIE FRICTION SHOCK ABSORBER

摘要

FIELD: railway transport; bolster suspension of freight car bogies. SUBSTANCE: wedge of shock absorber engaging through inclined part with over-spring beam and through vertical part, with friction plate of side frame, is reinforced in upper and lower parts over sections equal to 1/3 of length of friction surface. Corresponding surfaces of friction plate and over-spring beam are reinforced in middle zone of contact with wedge over value equal to 1/3 of friction surface. Surface friction coefficients are in inverse proportion to loads. EFFECT: enhanced reliability of operation. 2 dwgo
