Description

Shock-absorbing wheel hub

The utility model relates to wheel nave, and is concrete relevant with the wheel hub of wheels such as bicycle, boosted vehicle, motor bike.

Traditional bicycle, help the wheel nave of Che Li and motor bike not have the function of damping, but realize damping by spoke wire on its wheel rim and the seat cushion spring under the seat cushion, the shortcoming that this damping modes exists is: the damping direction is limited, and damping effect is not good enough.

The purpose of this utility model is that a kind of Shock-absorbing wheel hub will be provided, and with its equipped bicycle, boosted vehicle and bike wheel, can provide omnirange, respond well damping.

The utility model comprises parts such as bearing carrier ring or axle sleeve, volute spring, spacing garden plate, wheel hub case.Intermediate sleeve is equipped with a volute spring outside bearing carrier ring or axle sleeve; A spacing garden plate respectively is equipped with in volute spring two outsides on bearing carrier ring or axle sleeve; Refilled the wheel hub case at the volute spring and the plate outside, two spacing gardens, one of volute spring is connecting the bearing carrier ring or the axle sleeve outside, and the other end is then connecting wheel hub case inboard, has the spoke hole of interspersed spoke wire on wheel hub case two all side stages limits.

The utlity model has following advantage: 1. owing in the wheel hub volute spring is housed, it is big that it plays spoke, and this just makes that its damping effect is better; And can in the wheel hub case, adjust variation by full garden Zhou Fangxiang with volute spring, so can realize comprehensive damping, thus increase by bus the comfort and the sense of security.2. this wheel hub structure is simple, cost is low, be easy to production.3 both can use separately on vehicle, can be merged use with original damping accessory on the vehicle again.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
