  • Patent number: 9394953
    Abstract: 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 includes 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 is 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.
