Abstract

The invention belongs to the technical field of bicycle hubs. An adjustable eccentric bicycle hub, comprising a hub tube, the hub tube is provided with an end cover, the end cover is provided with a chute, the hub tube is provided with a gear box, the wheel shaft passes through the chute, and the hub tube is connected with a telescopic rod; The aforementioned wheel shaft is parallel to the drive shaft. Gear A, slider and gear B are sleeved on the wheel shaft. Driven gear A, driven gear B and helical teeth are arranged on the drive shaft. The helical gear drives the helical gear to rotate. When the helical gear rotates The telescopic rod is driven to extend and contract; the gear A is connected with the driven gear A, and the gear B is meshed with the driven gear B for transmission; the sliding part is connected with the adjusting rod. The overall structure and control aspects of the present invention are reasonable, reliable 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 common bicycles are arranged at a fixed position in the center, and such wheel hubs can be used for general means of transportation when the wheels are 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-mentioned shortcomings, the object of the present invention is to provide a reasonable, reliable and durable adjustable eccentric bicycle hub, 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 to achie...
