Title:

BRAKE LINING FOR ROLLING STOCK

Document Type and Number:

WIPO Patent Application WO/2011/081178

Kind Code:

A1

Abstract:

Equal surface pressure is applied and an elastic member is protected. A brake lining for a rolling stock is pressed, by means of a brake caliper, against the sliding surface of a brake disk bolted to an axle or a disk body attached to the axle. The brake lining for a rolling stock is provided with friction members (11) pressed against the sliding surface of the brake disk, and a rear plate (12) which is attached to the brake caliper and which supports the friction members (11). The friction members (11) are separated and disposed on the radial direction and the circumferential direction of the brake disk. A disk spring (13) is placed between the friction members (11) and the rear plate (12). The surface of the friction members (11) which opposes the rear plate (12) is in the shape of a sphere. When pressed lightly, a pressing force is transferred to the friction members (11) from the rear plate (12) via the disk spring (13). When pressed strongly, a pressing force is directly transferred to the friction members (11) as the rear plate (12) and the spherical sections (11a) come into contact. As a consequence, an equal surface pressure is applied, and deformation and degradation of an elastic member can be prevented.
