[0003] The brake device in some bicycle hubs needs to use a brake cone. In order to avoid the loosening and rotation of the brake cone, the brake cone is usually limited by a fixed arm. The fixed arm extends to the outside of the hub and then connects with the frame. In the actual application process , the fixed arm is bulky, the installation is cumbersome, the stability is poor, and it needs to be improved

The invention discloses a brake fixing device of a bicycle hub.The brake fixing device comprises rear fork claws, a central shaft and a hub barrel.The hub barrel is arranged on the central shaft in a sleeving mode, the rotating shaft is erected on the rear fork claws, a driving screw sleeve and a brake cone are arranged on the central shaft, and are arranged at the two ends of the hub barrel respectively, a slope corresponding to a brake pad is arranged at the tail end, extending to the inner side of the hub barrel, of the brake cone, a strip-shaped block is arranged at the front end, extending to the outer side of the hub barrel, of the brake cone, a threaded hole penetrating through the brake cone is formed in the middle of the strip-shaped block, and the brake cone is of an integrated structure or a split structure.In this way, according to the brake fixing device of the bicycle hub, a fixing arm is omitted, the strip-shaped block on the brake cone is directly connected with the rear fork claws, the structure is compact, the brake cone is prevented from loosening or rotating, and mounting and dismounting convenience is good.
Description
technical field [0001] The invention relates to the field of bicycles, in particular to a bicycle hub brake fixing device. Background technique [0002] Bicycle hub, commonly known as "hub barrel", is a barrel that is sleeved on the outside of the bicycle wheel axle to connect the spokes. The two ends of the barrel are respectively provided with a circle of holes for fixing the spokes. Ordinary bicycle hubs are provided with bearings corresponding to the wheel axles, and the bearings are used to support the rotation of the hubs. However, some bicycle hubs can realize the braking function, and brake devices need to be installed in the bicycle hubs. [0003] The brake device in some bicycle hubs needs to use a brake cone. In order to avoid the loosening and rotation of the brake cone, the brake cone is usually limited by a fixed arm. The fixed arm extends to the outside of the hub and then connects with the frame. In practical application , The fixed arm is bulky, cumbersome ...
