Abstract
The utility model discloses a noiseless rear hub of a bicycle. The noiseless rear hub of the bicycle comprises a hub body, a ratchet wheel and a sleeve, wherein the ratchet wheel is connected with the hub body through an adapting piece and connected with the sleeve through one-way pawls. Due to the design of the one-way pawl, the noiseless rear hub of the bicycle is capable of evenly distributing strength on each pawl, the effect of application of force can reach a hundred percent, not only can the hub be noiseless in the process of riding, but also the hub can be directly driven and no ullage can be occurred in the process of riding when chainwheels are stepped at any time.
Description
Technical field:
The utility model relates to the bicycle spare parts and accessories technical field, especially relates to a kind of bicycle hub structure.
Background technology:
Bicycle rear-hub structure in the prior art, riding when sailing, all can send the sound, reason is flower-drum in the market, the distance of ratchet and pawl position, produce Ullage, can be directly not stressed in the application of force, after must making ratchet and the ratchet position contacting, just can produce power, therefore in riding the process of sailing, can produce the sound because of idle running.
The utility model content:
The purpose of this utility model is to provide the weak point that exists for prior art and a kind of noiseless bicycle rear-hub when sailing of riding is provided.
For achieving the above object, noiseless bicycle rear-hub of the present utility model includes flower-drum body, ratchet, sleeve, and described ratchet is connected with the flower-drum body by attaching parts, and described ratchet is connected with sleeve by unidirectional ratchet.
Preferred as technique scheme, described unidirectional ratchet comprises circular pawl body and is arranged on the ratchet of pawl body inner edge.
Preferred as technique scheme, described ratchet quantity is more than two.
The beneficial effects of the utility model are: because the design of unidirectional ratchet, can be with strength on average on each ratchet, application of force effect is reached very, not only make flower-drum drive middle without any noise, and cross in the journey riding, whenever step on and pedal sprocket wheel, all can directly drive flower-drum, do not have Ullage and produce.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of unidirectional ratchet of the present utility model.
The specific embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
See illustrated in figures 1 and 2: noiseless bicycle rear-hub of the present utility model includes flower-drum body 1, ratchet 2, sleeve 3, described ratchet 2 is connected with flower-drum body 1 by attaching parts 4, described ratchet 2 is connected with sleeve 3 by unidirectional ratchet 5, and described unidirectional ratchet 5 comprises circular pawl body 51 and is arranged on a plurality of ratchets 52 of pawl body 51 inner edges.
The utility model is installed on rides on the bicycle when sailing, and sprocket wheel band moving sleeve 3 rotates, and makes it pass through unidirectional ratchet 5 and drives ratchet 2 rotations, and ratchet 2 drives flower-drum bodies 1 by attaching parts 4 and rotates.
