Problems solved by technology
[0002] The bicycle is a well-known means of transportation. When the bicycle wheel rotates relative to the axle, there is a large sliding friction between the hub and the axle. The bearing hub (or ball hub) effectively converts the sliding friction into rolling friction. To ensure smooth riding and prolong the service life of the bicycle, but the manufacturing precision of bearing hub (or ball hub) is high and the price is expensive. At the same time, the assembly process is time-consuming and labor-intensive

A bicycle hub structure includes an axle, a shaft tube, side covers, fasteners, flange bearings, bushings and a drum body. The axle comprises a T-shaped axle center and a flange nut rotated at one endof the T-shaped axle center, the shaft tube is sleeved on the outside of the T-shaped shaft center, the shaft tube is a diameter-changing tube two ends of which are machined with tooth lines, the side covers are sleeved on the tooth lines and locked by the fasteners, the drum body is installed in the middle of the shaft tube, the bushings are installed at the concave parts of the two ends of thedrum body, and the flange bearings are installed at the inner holes of the bushings. The flange bearings replace Pellin bearings (or ball bearings), which reduce the manufacturing cost and facilitatethe installation and maintenance. At the same time, the test results show that the rolling performance of a bicycle is better and the service life of flange bearings is longer.
Description
technical field [0001] The invention relates to the technical field of bicycles, in particular to a bicycle hub structure. Background technique [0002] The bicycle is a well-known means of transportation. When the bicycle wheel rotates relative to the axle, there is a large sliding friction between the hub and the axle. The bearing hub (or ball hub) effectively converts the sliding friction into rolling friction. It ensures smooth riding and prolongs the service life of the bicycle. However, the manufacturing precision of bearing hubs (or ball hubs) is high and the price is expensive. At the same time, the assembly process is also time-consuming and labor-intensive. Contents of the invention [0003] Aiming at the deficiencies in the above problems, the present invention provides a bicycle hub structure. [0004] To achieve the above object, the present invention provides a bicycle hub structure, comprising: [0005] Axle, axle tube, side cover, fastener, flange bearing...
