Layered spacer ring for a disk brake and the layered spacer ring unit

摘要

A layered spacer ring (2) for a disc brake, for example, a block spacer ring (20) and a pressure part spacer ring (21) to a simultaneous. On the block spacer ring (20) is arranged at the rear side of a back plate (30) of a block (3) is provided. On the pressure part spacer ring (21) is connected between the block for strength spacer ring (20) and a pressing part (12, 13a, 13b) is provided, which is used to adjust the block (3) against a rotor (r) to press. On the block spacer ring (20) has hooks (20a, 20b, 20c), which extend over a peripheral edge of the back plate (30) and are hooked on this. On the pressure part spacer ring (21) has hooks (21a, 21b, 21c), which extend over a surface of a corresponding block for strength hook (20a, 20b, 20c) extend. The one or more pressure part hooks (21a, 21b, 21c) are slidably with the top of the hooks (20a, 20b, 20c) of the block for strength spacer ring (20) in contact, in order to thus simply in an in-surface direction with respect to the block side spacer ring (20) and the rear plate (30) of the block (3) to slide.
