Abstract

The invention provides a disc brake for a bicycle. The disc brake comprises a brake disc, a hub shaft, a hub shell, a brake disc connecting piece, a mounting shaft sleeve and a locking piece, wherein the brake disc connecting piece is provided with a pipe-shaped main body provided with internal threads, and a ring-shaped lug boss; the mounting shaft sleeve is provided with a shaft sleeve main body and a disc connecting part; the locking piece is provided with a pipe-shaped part that is provided with external threads, and a flange; the external surface section of the pipe-shaped main body takes the structure of a polygon; bulges are arranged on the surface of the ring-shaped lug boss; the inner surface of a central hole of the shaft sleeve main body can be matched with the external surface of the pipe-shaped main body; concave pits that can be matched with the bulges are formed in the end surface, facing the brake disc connecting piece, of the shaft sleeve main body; when the external threads are matched with the internal threads, the inner surface of the mounting shaft sleeve is matched with the external surface of the pipe-shaped main body, and the bulges are matched with the concave pits, so that the mounting shaft sleeve is held by the locking piece and the brake disc connecting piece.

Description

technical field [0001] The invention relates to the field of bicycle brakes, more particularly to a bicycle disc brake. Background technique [0002] With the development of bicycle technology becoming more and more mature and people's higher requirements for green travel, bicycles are more and more used in daily life. Therefore, researchers have invested more energy in improving bicycle performance, especially on bicycle brakes. Currently used bicycle brake devices mainly include disc and drum types. Disc brakes are widely used due to their advantages such as quick response, stability and good heat dissipation. Existing disc brakes generally include A caliper operatively connected to the brake handle and a disc brake rotor fixedly connected to the hub of the wheel, wherein the disc brake rotor is connected to the hub in several ways, for example, through a bushing to the hub on the hub Corresponding splines cooperate with the connection and a locking ring to hold the brak...
