Detailed Description
As shown in fig. 1 and 2, the hub structure of the bicycle according to the embodiment of the invention comprises a wheel shaft 1, a shaft tube 2, a side cover 3, a fastener 4, a flange bearing 5, a bushing 6 and a hub body 7, wherein the wheel shaft 1 comprises a T-shaped shaft center 11 and a flange nut 12 screwed at one end of the T-shaped shaft center 11, the T-shaped shaft center 11 is fixedly arranged on a bicycle frame, the shaft tube 2 is sleeved outside the T-shaped shaft center 11, the shaft tube 2 is a reducer, threads 21 are machined at two ends of the reducer, the side cover 3 is sleeved on the threads 21 and locked by the fastener 4, the fastener 4 is a headless inner hexagonal screw, the hub body 7 is arranged in the middle of the shaft tube 2, the bushing 6 is arranged at the concave parts at two ends of the hub body 7, the flange bearing 5 is arranged in an inner hole of the bushing 6, the flange bearing 5 is formed by casting engineering plastics, the flange bearing 5 is in a flanging shape, the bushing 6 is in an interference fit with the flange bearing 5, the outer edge of the bushing 6 abuts against the flanging inner side of the flange bearing 5, the hub body 7 is in an interference fit with the bushing 6, the hub body 7 is made of iron or aluminum alloy material, and the hub body 7 is made of an interference spoke 71 is machined on the hub body 7.
The flange bearing replaces the support Lin Zhoucheng (or ball bearing), so that the manufacturing cost is reduced, the installation and the maintenance are convenient, and meanwhile, the test use shows that the rolling performance of the bicycle is better, and the service life of the flange bearing is longer.
When in specific use, the invention is described with reference to the drawings for convenient understanding;
in the prior art, the bicycle realizes the conversion from sliding friction to rolling friction through a Pelin bearing or a ball bearing, in the structure of the invention, the Pelin bearing or the ball bearing is replaced by a flange bearing, the flange bearing is made of engineering plastics, the friction performance is better, the abrasion is small, the service life is prolonged, meanwhile, the flange bearing is very convenient to install and replace, the manufacturing cost is low, the bicycle has another great advantage relative to the Pelin bearing or the ball bearing, in the rolling process, the axle tube and the axle are relatively static, the hub body, the bushing and the flange bearing rotate at the same speed (the three are installed together through interference), and friction surfaces are formed between the flange bearing and the axle tube and between the flange bearing and the side cover.
