Abstract

The invention belongs to the technical field of a bicycle wheel hub. The bicycle wheel hub comprises a hub pipe which is provided with an end cover; a sliding groove is formed in the end cover; a gear box is arranged in the hub pipe; a wheel axle passes through the sliding groove; the hub pipe is connected with a telescopic rod; the wheel axle is parallel to a drive shaft; a gear A, a sliding piece and a gear B sleeve the wheel axle; the drive shaft is provided with a driven gear A, a driven gear B and a worm gear; a worm wheel is driven to rotate by the worm gear; when the worm wheel rotates, the telescopic rod is driven to extend and contract; the gear A is in transmission connection with the driven gear A; the gear B is in meshing transmission with the driven gear B; the sliding piece is connected with an adjusting lever. The bicycle wheel hub is reasonable and reliable in whole structure and control aspect, and durable.

Description

technical field [0001] The invention belongs to the technical field of bicycle hubs. Background technique [0002] The wheel hub and axle of a common bicycle are arranged at a fixed position at the center of the wheel, and such a wheel hub can be used as a general means of transportation when the wheel hub is installed. There is also a bicycle design that can adjust the wheel shaft and wheel eccentricity to play the ups and downs of the bicycle during riding through patent retrieval. However, it is not reasonable enough in terms of overall structural integrity and control, resulting in low reliability and durability of parts and easy damage. Contents of the invention [0003] In order to solve the above disadvantages, the object of the present invention is to provide a bicycle hub with reasonable structure, reliability and durability, which is easy to operate to convert the eccentricity of the wheel shaft and restore the center state of the wheel shaft. [0004] In order...
