COMPOSITE BRAKING CLAMP 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. Braking clamp comprises steel carcass and arc-like body consisting of clamp body main part and shaped part with groove made therein. Arc-like body consists of separate elements secured at steel carcass. Elements of clamp body main part are made of friction material while and those of shaped part are made of antifriction material. Friction material friction factor is 1.5-10 times higher and abrasion resistance 1.5-3.5 times higher than those of antifriction material. Friction elements of clamp main part feature different height. Higher friction elements are located at steel carcass edges.

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