<P>PROBLEM TO BE SOLVED: To provide a brake lining and a disc brake for a railway vehicle capable of achieving 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. <P>SOLUTION: The disc brake for railway vehicles is equipped with a brake disc 1 that is fixed to the wheel or axle of a railway vehicle and a brake lining 2 that is pressed against the sliding surface 1a of the brake disc 1 by brake calipers. The brake lining 2 is obtained from: multiple friction members 3, the respective surfaces of which face the sliding surface 1a of the brake disc 1, each friction member 3 being disposed with gaps therebetween; back metals 4 secured to the back surfaces of every friction member 3; and a substrate 6, which supports every friction member 3 from the back surface via a spring member 5 and which is installed on the brake calipers. With two adjacent friction members 3 as a set, the back metal 4 of the set of friction members 3 is a single piece. <P>COPYRIGHT: (C)2013,JPO&INPIT |
