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.

摘要： There is provided a brake lining for railway vehicle that can reduce brake squeal in braking. A brake lining (10) for railway vehicle is used for a disc brake system of a railway vehicle. This brake lining (10) includes a base plate (40), a sintered friction material (20), and a friction material supporting mechanism (30). The friction material supporting mechanism (30) is disposed between the base plate (40) and the sintered friction material (20) and supports the sintered friction material (20) in such a manner that the sintered friction material (20) can move with respect to the base plate. The sintered friction material (20) has a Young's modulus of 35.0 GPa or more.

摘要： A brake lining (2) is provided that is to be pressed against a sliding surface of a brake disk fastened to a wheel or an axle of a railway vehicle. The brake lining (2) includes: a plurality of friction members (3) arranged to be spaced from each other, each of the friction members having a front surface that is to face the sliding surface of the brake disk; a back board (4) fastened to a back surface of each of the friction members (3); and a base plate (6) supporting each friction member (3) at a region including a center portion of the respective friction members (3), wherein a spring member is disposed between the base plate (6) and the back boards (4) on a back surface side of the respective friction members (3). Two friction members (3) that are adjacent to each other are taken as a pair, and the back board (4) that is fastened to the pair of friction members (3) is a one-piece member, and a width of the back board (4) at a space between the friction members (3) of the pair of friction members (3) is greater than a width of the friction member (3). Brake squeal can be decreased by this brake lining. The brake lining is easily applied to existing vehicles, and manufacture management of the brake lining is simple.
