Description

shock-absorbing hub for bicycle

Technical Field

The utility model belongs to the technical field of bicycle spare part, concretely relates to kinds of bicycle shock attenuation flower-drums.

Background

The bicycle has been slowly changed into kinds of leisure activities that possess the motion and be good for physical and mental health by kind of traditional tools of riding instead of walk, green trip has been advocated to the time and the world, bicycle green, healthy when being first, folding bicycle is owing to carry storage and transportation convenience, receive public favor more, be the sports leisure, good instrument of commuting to go out, traditional bicycle does not set up the mechanism that slows down ground and produce the impact force to the vehicle on the market at present, make the rider's health bear direct impact shock, thereby produce discomfort or injury etc., consequently, some auxiliary device have been increased along with the development of bicycle, improve the comfort and the convenience of riding of bicycle, including the fork that shakes away, leading bumper shock absorber, head tube bumper shock absorber, soft tail frame, high-elastic cushion, the shock attenuation flower-drum that shake away seat tube and the interior contain the gum cover etc., but all can all increase the weight of bicycle by different degrees, the installation is complicated, mechanism cost is high, the maintenance degree is big.

SUMMERY OF THE UTILITY MODEL

The utility model provides a prior art not enough, provide kinds of bicycle shock attenuation flower-drum that have flower-drum axle and flower-drum barrel eccentric structure and spring shock-absorbing component, simple structure, action are reliable, have improved the comfort level of riding greatly.

kinds of bicycle shock attenuation flower-drums, including the flower-drum axle, flower-drum axle both ends cover is equipped with the axle bumper, the cover is equipped with eccentric circular end cover in the axle bumper, eccentric circular end cover outer end is equipped with the bearing, just the cover is equipped with the drum barrel on the bearing, drum barrel axle center and drum barrel axle center are not on same axis, the appearance intracavity between drum barrel and the drum barrel axle is provided with spring shock attenuation subassembly.

Preferably, the spring damping assembly comprises a damping spring, a spring pressing block and a guide shaft, the spring pressing block is arranged at sides at two inner ends of the eccentric circular end cover, the guide shaft is arranged between the spring pressing blocks in a penetrating mode, the spring pressing block slides in a reciprocating mode along the guide shaft, the damping spring is arranged on the shaft of the hub in a surrounding mode and located on the shaft of the hub in the hub, and a bidirectional multi-thread is arranged on the shaft of the hub in the hub.

More preferably, the damping spring is kinds of compression spring, torsion spring, serpentine spring and torsion bar spring.

, it is further preferable that the two ends of the hub axle are hexagonal.

it is further preferred that the outer end of the eccentric circular end cap is flush with the outer end of the bearing.

Compared with the prior art, the utility model has the beneficial effects that kinds of bicycle shock attenuation flower-drums, the flower-drum axle forms eccentric structure with the flower-drum barrel, still be provided with spring shock attenuation subassembly in the flower-drum barrel, receive the ground impact force when the flower-drum barrel, because eccentric structure flower-drum barrel can be around flower-drum axle luffing motion to axial through spring shock attenuation subassembly is flexible can cushion, makes the ground impact can not directly transmit to the frame on, thereby reaches the absorbing effect of in-process of riding.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the shaft of the drum of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

kinds of bicycle shock attenuation flower-drums, refer to fig. 1, fig. 2, including the flower-drum axle 1, the cover of 1 both ends of flower-drum axle is equipped with axle bumper 4, the cover is equipped with eccentric circular end cover 5 in the axle bumper 4, the outer end of eccentric circular end cover 5 is equipped with bearing 3, and the cover is equipped with the drum barrel 2 on the bearing 3, the axle center of drum axle 1 is not on the same axis with drum barrel 2 axle center, be provided with spring damper assembly 6 in the appearance chamber between drum barrel 2 and the flower-drum axle 1, when drum barrel 2 receives ground impact force, because eccentric structure drum barrel 2 can encircle drum axle 1 luffing motion to can cushion through the axial expansion of spring damper assembly 6, make the ground impact can not directly transmit to the frame, thereby reach the absorbing effect in the process of riding.

With continued reference to fig. 1 and 2, the spring damping assembly 6 includes a damping spring 61, a spring pressing block 62 and a guide shaft 63, the spring pressing block 62 is disposed at two inner ends sides of the eccentric circular end cover 5, the guide shaft 63 is disposed between the spring pressing blocks 62 in a penetrating manner, the spring pressing block 62 slides along the guide shaft 63 in a reciprocating manner, the damping spring 61 is disposed on the drum shaft 1 in a surrounding manner, a bidirectional multiple thread 11 is disposed on the drum shaft 1 located in the drum barrel 2, the spring pressing block 62 is matched with the drum shaft 1 through the multiple thread 11, when the drum barrel 2 is subjected to a ground impact force, the drum barrel 2 swings up and down around the drum shaft 1 due to the eccentric structure, the bidirectional multiple thread 11 disposed on the drum shaft 1 in the drum barrel 2 drives the guide shaft 63 and the spring pressing block 62 to swing simultaneously, and the spring pressing block 62 generates an axial motion through the multiple thread 11, so that the damping spring 61 rebounds and compresses, thereby achieving the purpose of damping.

With continued reference to fig. 1 and 2, the damping spring 61 is types of compression spring, torsion spring, serpentine spring, and torsion bar spring.

With continued reference to fig. 1 and 2, the two ends of the shaft 1 of the drum are connected to the hexagonal connection 12.

With continued reference to fig. 1 and 2, the outer end of the eccentric circular end cap 5 is flush with the outer end of the bearing 3.

When the bicycle is ridden, the wheels are transmitted to the drum barrel 2 by the ground impact, the drum barrel shaft 1, the drum barrel 2 and the guide shaft 63 form a three-axis eccentric mechanism, and the drum barrel 2 can swing up and down around the drum barrel shaft 1 due to the eccentric structure and can be buffered by the axial extension of the spring damping assembly 6, so that the ground impact cannot be directly transmitted to the frame, and the damping effect in the riding process is achieved.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the present invention, so that all equivalent changes made by the contents of the claims of the present invention should be included in the scope of the claims of the present invention.
