    • A brake lining for a railroad car brake includes friction members which are pressed onto the sliding surface of a brake disc, and a back plate which is attached to a brake caliper in order to support the friction members. The friction members are dividedly arranged in a radial direction and in a circumferential direction of the brake disc. A disc spring is disposed between each respective friction member and the back plate. An outer peripheral surface of the friction members facing the back plate is formed in a convex curved shape in an area outside the elastic member. When a light pressing force is applied, a pressing force is transmitted from the back plate to the friction members via the disc springs. When a heavy pressing force is applied, the back plate and a rounded surface portion make contact, thereby directly transmitting a pressing force to the friction members.
    • 用于铁路车辆制动器的制动衬片包括被压在制动盘的滑动表面上的摩擦构件和附接到制动钳以支撑摩擦构件的后板。 摩擦构件沿径向方向和制动盘的圆周方向分开设置。 碟形弹簧设置在每个相应的摩擦构件和后板之间。 面对背板的摩擦构件的外周面在弹性构件外部的区域中形成为凸曲面形状。 当施加轻压力时,压力通过盘形弹簧从背板传递到摩擦构件。 当施加重压力时,背板和圆形表面部分接触,从而直接将摩擦件传递给摩擦件。
