PIN JOINT FOR ROD LONGITUDINAL BRACING OF BOGIE WITH LOCOMOTIVE BODY Russian patent published in 2009 - IPC B61F5/02 

FIELD: mechanical engineering.

SUBSTANCE: invention is attributed to the field of vehicle engineering. Pin joint contains intermediate unit connected with it. The intermediate unit consists of central element with two resilient elements and rigid spherical joint of "ШС" type installed on it. Resilience centres of deformable elements system and "ШС"-type joint are aligned. Brackets may be performed as cylinder bushings-gudgeons with resilient elements of cylinder cured silentblock type installed on them. To adjust bogie longitudinal position relative to body the mating mounting spots on pin joint housing and on affixing surface of body frame are made with linear corrugated surface where corrugation has transversal direction relative to locomotive.

EFFECT: following is achieved: quantity reduction for energy absorbing material of resilient elements, mounting-dismantling works simplification, exclusion of possibility of constant shock-vibration loading of longitudinal bracing of bogie with locomotive body in operation modes and rigid shocks during shunting operation and in event of emergency runover.
