BRAKE SHOE OF RAILWAY VEHICLE Russian patent published in 2019 - IPC B61H1/00 F16D65/06 

FIELD: transportation.

SUBSTANCE: invention relates to railway transport, namely, to brake shoes of freight railroad vehicles, which form friction pair with rolling surface of railway wheel. Brake shoe of a railway vehicle includes a metal frame and a polymer composite friction element, in the center of which on the side of the working surface of the shoe a recess is made. Brake shoe is made with compressibility in radial direction at operating forces of clamping shoe to wheel, selected from ratio: C=0.1÷0.2P, where C is shoe compressibility, P is permissible wear on wheel rolling.

EFFECT: enabling the required performance of the shoe not only when mounted on the wheel without rolling, but also on wheels, rolling of which is close to the maximum allowable value.
