Friction pad assembly with return spring for air gap limitation for automotive partial lining disc brake

摘要

A friction pad assembly 5 for a floating caliper type automotive partial lining disc brake 1 having a back plate 14 and a return spring 10 made of a thin plate fixed to the back plate, the automotive partial lining disc Brake includes a brake holder 2 fixed to a vehicle in which the friction pad assembly 5 disposed on both sides of the brake disk is movably guided, and the brake disk and the friction pad assembly 5 are wrapped from above. A housing 3 which is supported by the brake holder 2 and, in this case, the return spring 10 between the brake holder 2 and the friction pad assembly 5 in the axial direction, By means of at least one spring leg 13, said return spring 0 to provide a gap on the friction pad assembly 5, it is possible jamming. The spring leg 13 encloses the hammerhead-shaped claw 6 of the back plate 14 from above, and in this case, in order to give the friction pad assembly 5 a constant sized gap, the spring leg 13 The leg 13 is formed to be plastically deformable for the purpose as a result of the reduction of the friction material thickness under the brake operation.
