RAIL CAR BRAKE LINING
摘要:
[OBJECT] To prevent friction bodies from rotating at their attached places. [MEANS] A brake lining for a railroad car in which a frictional surface of a brake disc is pressed by a brake caliper. The invention comprises friction bodies 11 pressed against the frictional surface of the brake disc, and a back plate 12 mounted to the caliper so as to support the friction bodies 11. The friction bodies 11 are distributed such that two or more thereof are arranged in a radial direction and in a circumferential direction of the brake disc. Each of the friction bodies 11 is formed with a friction material 11a which contacts the frictional surface of the brake disc, and with a base plate 11b attached on the back plate 12 side of the friction material 11a. The base plate 11b has a protrusion 11ba formed on the back plate 12 side. On the friction body 11 side of the back plate 12 there is formed a groove 12b which contacts the protrusion 11ba formed on the base plate 11b. A disc spring 14 or a spherical-seated structure 15 is disposed between the base plate 11b of each friction body 11 and the back plate 12. [ADVANTAGEOUS EFFECT] Friction bodies can be prevented from rotating at their attached places, without adding new components.
