Title:
RAIL CAR BRAKE LINING
Document Type and Number:
WIPO Patent Application WO/2011/111822
Kind Code:
A1
Abstract:
In order to prevent rotation at the installation position of a friction member, a rail car brake lining that is pressed against the sliding surface of a brake disc by a brake caliper is disclosed, which is equipped with friction members (11) that press against the sliding surface of the brake disc and a back plate (12) that is attached to the brake caliper in order to support the friction members (11). The friction members (11) are divided into at least two parts in the radial direction and the circumferential direction of the brake disc. Each of the friction members (11) are formed with a sliding material (11a) that comes into contact with the sliding surface of the brake disc, and a back metal (11b) that is fixed on the back plate (12) side of the sliding material (11a). Protrusions (11ba) are formed on the back plate (12) side of the back metal (11b). Grooves (12b) that come into contact with the protrusions (11ba) formed on the back metal (11b) are formed on the friction member (11) side of the back plate (12). Disc springs (14) or spherical seats (15) are interposed between the back plate (12) and the back metal (11b) of each friction member (11). As a result, rotation at the installation position of the friction members can be prevented without adding new components.
