IRON-BASED COMPOSITE BRAKE SHOE FOR RAILWAY CAR Russian patent published in 2014 - IPC B61H1/00 F16D65/04 F16D69/02

Abstract RU 2525609 C1

FIELD: transport.

SUBSTANCE: proposed brake shoe comprises steel carcass and arc-like body consisting of separate friction elements secured to steel carcass. Said elements are made of friction material. Guides and steel carcass have pressure plates to retain friction elements at steel carcass. Shoe friction element is shaped to prismatoid with trapezium-shaped bases. Said bases have recesses to accommodate steel carcass pressure plates. Ledge is made at one of lateral surfaces of friction element while recess is made at opposite side surface. Friction elements fitted in steel carcass are secured by squeezing of the carcass lateral pressure plates. Two extreme elements are additionally pressed by pressure plates of carcass guides. Friction elements are made of iron-base metal.

EFFECT: higher safety and wear resistance, better manufacturability.
