Oscillation damping device, for automobile brake, has oscillation cancellation element contained within hollow space formed within braking piston

摘要

The oscillation damping device has an oscillation cancellation element (6) freely contained within a hollow space (5), incorporated in the braking piston (4) of the brake cylinder (3), at a relative spacing (14) from the pressure plate (11) inserted between the braking piston and the brake disc (13). The oscillation cancellation element is formed by a hardened silicon carrier material (7), having a Shore hardness of at least 20 Shore, incorporating metallic mass elements (8).
