Abstract

The invention belongs to the technical field of bicycle wheel hubs. An adjustable eccentric bicycle wheel hub comprises a hub pipe, wherein the hub pipe comprises an end cover and the end cover is provided with a slide groove; the hub pipe is internally provided with a gear box; a wheel shaft penetrates through the slide groove; the hub pipe is connected with a retractable rod; the wheel shaft is parallel to a driving shaft; the wheel shaft is provided with a gear A, a slide piece and a gear B in a sleeving way; the driving shaft is provided with driven teeth A, driven teeth B and helical teeth; the helical teeth drive a helical gear to rotate; when the helical gear rotates, the retractable rod is driven to be stretched out and retracted; the gear A and the driven teeth A are in transmission connection; the gear B and the driven teeth B are in engaged transmission; the slide piece is connected with an adjusting rod. The adjustable eccentric bicycle wheel hub is reasonable and reliable in whole structure and control 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...
