Title:
BRAKE LINING FOR RAILWAY VEHICLES AND DISC BRAKES EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2012/164935
Kind Code:
A1
Abstract:
The disc brake for railway vehicles is equipped with a brake disc that is fixed to the wheel or axle of a railway vehicle and a brake lining that is pressed against the sliding surface of the brake disc by brake calipers. The brake lining is obtained from: multiple friction members, the respective surfaces of which face the sliding surface of the brake disc, each friction member being disposed with gaps therebetween; back metals secured to the back surfaces of every friction member; and a substrate, which supports every friction member from the back surface via a spring member and which is installed on the brake calipers. With two adjacent friction members as a set, the back metal of the set of friction members is a single piece. Disc brakes of said configuration achieve both homogenization of contact surface pressure between the brake lining and the brake disc during braking and stabilization of the coefficient of friction therebetween as well as improving durability and reliability.
