FIELD: transport.

SUBSTANCE: brake shoe comprises steel carcass and iron arched body furnished with grouped inserts. Insert abrasivity exceeds that of shoe body material. Said inserts are welded in place while the entire set is cast-in with iron to make integral working surface of the shoe. Said shoe has an extra metal carcass. Extra metal carcass incorporates inserts of the shoe body main section made of composite friction material, its friction factor exceeding that of the body, and lateral inserts composed of shaped elements in contact with locomotive tire flange surface interacting with rail 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: more efficient braking, lower noise and wear, increased MTBR, reliable and stable operation of brake systems.
