FIELD: transport.

SUBSTANCE: invention relates to railway transport, namely, to rolling stock braking equipment. Brake shoe comprises body equipped with friction elements embedded into said body on friction surface side. Body rear wall has hole to receive brake shoe attachment axle. Body rear walls have inner arched ribs on friction surface side. Friction elements have grooves on sides to be accommodated on said ribs. Side walls have holes to receive friction element ends limiters. Brake shoe attachment axle and friction element limiters support guide bracket for orientation of friction elements relative to wheel flange. Body rear wall has holes to remove heat from friction elements. Arched bearing surface of friction elements in contact with brake shoe body allows independent arrangement of every friction element relative to wheel friction surface.

EFFECT: simplified design, longer life and higher reliability.
