BRAKE LINING FOR RAILWAY VEHICLES AND DISC BRAKES EQUIPPED WITH SAME

摘要

A disc brake for railway vehicles includes: a brake disc fixed to a wheel or an axle of a railway vehicle; and a brake lining configured to be pressed against a frictional surface of the brake disc by a brake caliper, the brake lining including: a plurality of friction members arranged to be spaced from each other, each of the friction members having a surface that faces the frictional surface of the brake disc; a metallic backing secured to back surfaces of the friction members; and a base plate supporting the friction members on the back surface side via spring members, the base plate being mounted to a brake caliper; wherein the friction members are provided in pairs with each pair being formed by two adjacent ones of the friction members, and the metallic backing is a one-piece member provided for each pair of the friction members. The thus configured disc brake can achieve uniform contact pressure between the brake lining and the brake disc during braking operation while at the same time achieving a stable coefficient of friction between them, so that the durability and reliability are enhanced.
