BRAKE PAD WITH COMPOSITE INSERTS FOR LOCOMOTIVES AND RAIL MOTOR CARS Russian patent published in 2013 - IPC B61H1/00 F16D65/04 F16D69/02 

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly, to rolling stock braking equipment. Brake pad comprises steel carcass and iron arched body. Said arched body consists of the pad body main section furnished with cylindrical inserts arranged in groups and pad body shaped section with groove made therein to receive inserts to be fitted therein. Said pad has extra metallic carcass to support cylindrical inserts of the pas body main section and shaped section ridged inserts. Main section cylindrical inserts are made of composite friction material with friction factor higher than that of the base. Shaped section ridged inserts are composed of shaped elements fitted in pad grooves in the plane in contact with wheel tread flange interacting with tail side surface. Inserts are made of antifriction material with friction factor lower than that of the base and abrasiveness lower than that of the base and inserts fitted in pad body main section.

EFFECT: lower noise in braking, reduced wheel flange and side wear, increased locomotive MTBR, higher stability and reliability.
