RAILWAY TRANSPORT VEHICLE BRAKE BLOCK

摘要

FIELD: transport. ^ SUBSTANCE: brake block contains polymer composite friction element with cavity in its central part, metal frame and rigid inserts spaced at different sides of cavity. Rigid inserts are made with insert working part width equal to approximately one half of friction element working part width. Rigid inserts are located at different sides of friction element working part. ^ EFFECT: improvement of block operational performance due to providing solidity of frictional element with simultaneous keeping block flexibility and positive action of inserts on the whole rolling surface of wheel participating in friction contact. ^ 3 dwg
