Abstract
The utility model discloses an improved ratchet connecting structure of a bicycle rear hub. The improved ratchet connecting structure of the bicycle rear hub comprises a center and a hub body, the hub body is matched with the center through a bearing, and blades are arranged at the two ends of the outer portion of the hub body. One side of the hub body is provided with a ratchet and a chain wheel, the chain wheel is arranged at the front end of the ratchet; a ratchet ring, a spring and a ratchet claw are arranged on the inner end of the hub body, wherein the ratchet claw is arranged on the ratchet through the spring in a clamping mode; and the outer end of the ratchet ring is connected with the hub body in a threaded mode, and the inner end is matched with the ratchet claw. The improved ratchet connecting structure of the bicycle rear hub is less in parts, simple in structure, capable of reducing production cost, convenient in assembling, and capable of obviously reducing failure rate.
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 technique:
Bicycle rear-hub need arrange ratchet mechanism, and its ratchet linkage structure of the bicycle rear-hub of seeing in the market is complicated, and component are more, not only increased cost of production, and assemble very trouble, the rate of fault in the using process is also higher, is necessary to be improved.
The model utility content:
The purpose of this utility model is to provide the deficiency that exists for prior art and a kind of improved bicycle rear-hub ratchet linkage structure is provided, and it has characteristics simple in structure, easy to assembly, that the operational failure rate is low.
For achieving the above object, improved bicycle rear-hub ratchet linkage structure of the present utility model includes the car heart and flower-drum body, the flower-drum body cooperates with the car heart by bearing, and its outside two ends have blade, and a side of flower-drum body is provided with ratchet and sprocket wheel, sprocket wheel is installed on the ratchet front end, the inner of flower-drum body is provided with ratchet ring, spring, ratchet pawl, and wherein, ratchet pawl is located on the ratchet by spring clip, the ratchet ring outer end is threaded with the flower-drum body, and the inner cooperates with ratchet pawl.
Preferred as technique scheme, described sprocket wheel is threaded with ratchet.
The beneficial effects of the utility model are: the component of its ratchet linkage structure are less, and are simple in structure, not only reduced cost of production, and assemble very conveniently, and the operational failure rate also significantly reduces.
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.
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.
As shown in Figure 1: improved bicycle rear-hub ratchet linkage structure of the present utility model includes the car heart 10 and flower-drum body 20, flower-drum body 20 cooperates with the car heart 10 by bearing 30, its outside two ends have blade 40, one side of flower-drum body 20 is provided with ratchet 50 and sprocket wheel 60, sprocket wheel 60 is threadedly connected to ratchet 50 front ends, the inner of flower-drum body 20 is provided with ratchet ring 70, spring 80, ratchet pawl 90, wherein, ratchet pawl 90 is fastened on the ratchet 50 by spring 80, ratchet ring 70 outer ends are threaded with flower-drum body 20, and the inner cooperates with ratchet pawl 90.
When sprocket wheel 60 was subject to the traction rotation of chain, the ratchet 50 that is threaded with sprocket wheel 60 rotated thereupon, and ratchet 50 drives ratchet rings 70 by ratchet pawl 90 and rotates, and ratchet ring 70 drives again flower-drum body 20 and rotates, thus the driving wheel.
