METAL-CERAMIC FRICTION LINING FOR DISC BRAKE OF RAILWAY VEHICLE

摘要

railway transport. SUBSTANCE: friction lining has five friction sectors with rounded corners spaced from one another. Every sector is connected rigidly with metal base layer, shape of which corresponds to that of given friction member. Segmental friction members are positioned and secured at the rear side. Central segmental friction member is made symmetrical relative to plane passing through axis of rotation of radius describing external arc-shaped contour. Other segmental friction members arranged on each side of central segmental member are of asymmetrical form. Area of fitting of middle side segmental friction member and larger than area of fitting of extreme segmental friction member. EFFECT: enhanced operating longevity. 3 cl, 2 dwg
