Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-4, the present invention provides a technical solution: a shock absorption hub structure comprises a hub shaft 1, wherein the outer surface of the hub shaft 1 is rotatably connected with a shaft sleeve 3 through a plurality of bearings 2, the outer surface of the shaft sleeve 3 is fixedly connected with a shock absorption sleeve 4, the outer surface of the shock absorption sleeve 4 is fixedly connected with a hub sleeve 5, and two ends of the outer surface of the hub sleeve 5 are fixedly connected with hub disks 6;

the surface of axle sleeve 3 is along its length direction fixedly connected with a plurality of outer spacing rings 8 evenly at an interval, and the internal surface of hub cover 5 is along its length direction fixedly connected with a plurality of interior spacing rings 9 evenly at an interval, and the internal surface and the surface of shock attenuation cover 4 all set up the draw-in groove corresponding with a plurality of outer spacing rings 8 and a plurality of interior spacing rings 9 respectively and adaptation along its length direction.

In this embodiment, damping sleeve 4 is the elasticity material, it self has certain rigidity, but can produce certain deformation when the atress, simultaneously can become original state at once when not the atress, damping sleeve 4 in this flower-drum structure is located between axle sleeve 3 and flower-drum cover 5, in-process that the bicycle went, when the bicycle moved to the highway section of jolting, the wheel can produce vibrations, and vibrations can be transmitted to flower-drum dish 6 and flower-drum cover 5 through the spoke on the wheel on, finally can transmit the inside to the flower-drum, thereby cause the damage to the inside flower-drum axle 1 isotructure of flower-drum, but in this flower-drum structure, damping sleeve 4 can cushion vibrations, reduce its destructive power, thereby carry out certain protection to axle sleeve 3 and inside flower-drum axle 1, and people when riding, because vibrations reduce, just also can be more steady when riding, experience impression is improved.
