Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Please refer to Figures 1-4, the utility model provides a technical solution: a shock-absorbing hub structure, including a hub shaft 1, the outer surface of the hub shaft 1 is rotatably connected to a shaft sleeve 3 through a plurality of bearings 2, and the shaft sleeve 3 The outer surface is fixedly connected with a shock absorber 4, the outer surface of the shock absorber 4 is fixedly connected with a hub cover 5, and both ends of the outer surface of the hub cover 5 are fixedly connected with a hub disc 6;

The outer surface of the shaft sleeve 3 is fixedly connected with a plurality of outer limit rings 8 evenly spaced along its length direction, and the inner surface of the hub sleeve 5 is fixedly connected with a plurality of inner limit rings 9 evenly spaced along its length direction. Both the inner surface and the outer surface of the sleeve 4 are provided with engaging grooves corresponding to and adapted to the plurality of outer limiting rings 8 and the plurality of inner limiting rings 9 along the length direction thereof.

In this embodiment, the shock-absorbing sleeve 4 is made of elastic material, which itself has a certain rigidity, but it can produce a certain deformation when it is stressed, and it will immediately return to its original state when it is not stressed. The shock-absorbing sleeve 4 is located between the axle sleeve 3 and the hub sleeve 5. During the running of the bicycle, when the bicycle moves to a bumpy road, the wheel will vibrate, and the vibration will be transmitted to the hub disc 6 and hub disc 6 through the spokes on the wheel. On the hub sleeve 5, it will eventually be transmitted to the inside of the hub, thereby causing damage to the hub shaft 1 and other structures inside the hub. However, in this hub structure, the shock-absorbing sleeve 4 can buffer the vibration and reduce its destructive force. The sleeve 3 and the hub shaft 1 inside are protected to a certain extent, and when people ride, because the vibration is reduced, the ride can be more stable and the experience can be improved.

The outer limiting ring 8 and the inner limiting ring 9 are compatible with multiple draw-in slots on the shock absorbing sleeve 4, which can play a fixed limit on the shock absorbing sleeve 4 to prevent the shock absorbing sleeve from being damaged when the bicycle is riding. 4 out of the hub, which improves the structural strength of the entire hub.

Further, the outer surfaces of the two hub discs 6 are transversely opened with a plurality of spoke holes 7 , and the plurality of spoke holes 7 are evenly spaced along the circumferential direction of the hub disc 6 .
