Abstract
The utility model relates to a sprocket sleeve set integrated with a bicycle and is mainly provided with an integrated sprocket sleeve set. The sprocket sleeve set comprises a sprocket set and a sleeve set, wherein, the sleeve set is positioned in an annular concave chamber of a hub, a non return ratchet of the sleeve set is meshed with a non return ratchet ring in the annular concave chamber, which ensures that the sprocket sleeve set drives the hub to rotate only in one direction, and the sprocket set is connected with a drive chain.
Description
Technical field
The utility model relates to bicycle hub, especially a kind of chain wheel sleeve group that is made into integration that does not need the secondary assembling can directly place in the colored hub and connect the transmission latticing.
Background technology
As shown in Figure 1, for existing flower hub group perspective exploded view, include a sleeve 1, a chain wheel set 2 and a flower hub 3, and combine by the three; These sleeve 1 one ends cooperate a transmission component 1A to insert in this flower hub 3, the other end then screws with screw thread with chain wheel set 2, relend by this chain wheel set 2 connection driving chain (not shown), utilize this chain wheel set 2 of driving chain transmission, make chain wheel set 2 rotate and drive this flower hub 3 and rotate.
In actual use, the colored hub group of above-mentioned prior art has following defective:
The first, this sleeve 1 is two independent members with chain wheel set 2, and therefore making to go up needs the secondary processing moulding, and is very consuming time, and cost is too high.
The second, this sleeve group 1 can't the direct connection driving chain in the operation, so must can connect driving chain again by this chain wheel set 2 earlier to be threaded in this chain wheel set 2, therefore needs cost secondary built-up time, and is very consuming time, and uses inconvenience.
Therefore, the chain wheel sleeve group that provides a kind of bicycle to be made into integration is provided main purpose of the present utility model, and it is made chain wheel set and sleeve group with one-body molded, does not need secondary to make and assembling, and has reduced cost.
Relevant technology contents of the present utility model and detailed description, existing with a preferred embodiment, and conjunction with figs. is described as follows.
Description of drawings
Fig. 1 is existing flower hub group perspective exploded view.
Fig. 2 is the utility model perspective exploded view.
The specific embodiment
Referring to shown in Figure 2, be the utility model schematic perspective view, as shown in the figure:
The utility model is the chain wheel sleeve group that a kind of bicycle is made into integration, it mainly has the chain wheel sleeve group 10 that is made into integration, this chain wheel sleeve group 10 includes chain wheel set 11 and sleeve group 12 two parts, wherein this chain wheel set 11 has a plurality of tooth portion 110, be connected with the driving chain (not shown) by this tooth portion 110, form drive connection, be arranged with a plurality of unidirectional ratchets 120 on these sleeve group 12 external diameters in addition, this unidirectional ratchet 120 can upper and lower elasticity activity;
In view of the above, the sleeve group 12 of chain wheel sleeve group 10 is inserted in advance in the annular cavity 21 of colored hub 20, and utilize the unidirectional ratchet 120 of this sleeve group 12 and these annular cavity 21 interior single direction ratchet rings 210 to mesh, make this chain wheel sleeve group 10 only can drive flower hub 20 and rotate with single direction.
The utility model is made chain wheel set 11 and sleeve group 12 in one-body molded mode, but make its stock production, make, and effectively reduce assembling, the cost and the time of making, utilize this chain wheel set 11 directly to be connected with flower hub 20 and driving chain with sleeve group 12, form drive connection, and do not need shown in the existing colored hub group of Fig. 1, this existing sleeve 1 needs first interlocking one chain wheel set 2, can connect driving chain by chain wheel set 2 and make its transmission, chain wheel sleeve group 10 of the present utility model only needs one-stop operation promptly to finish assembling and reaches the transmission effect, also promptly compares with existing flower hub group to have preferable progressive effect really.
