Description
Technical field
The utility model relates to a kind of wheel hub, particularly relates to the outer pawl formula ratchet wheel hub of a kind of complete loose pearl type.
Background technique
Consult Fig. 1, the outer pawl formula ratchet wheel hub of existing one, as TaiWan, China patent announcement number No. I252815 " outer pawl formula ratchet wheel hub " invention case, comprise clutch unit 20, that housing 10, that an axle 9, is sheathed on this axle 9 is revolvably arranged at this housing 10 inside to connect this clutch unit 20 this actuator 30 and material are the chain wheel carrier 40 of aluminum alloy and the actuator 30, that material is chrome-moly steel is spirally connected, and four bearings 50.This housing 10 passes through wherein two bearings 50 and is connected with this axle 9.This chain wheel carrier 40 is connected with this axle 9 by two other bearing 50, and in order to meet modern to the light-weighted demand of bicycle, and with hardness, the lower and aluminum alloy of lighter in weight makes this chain wheel carrier 40.But, described bearing 50 is the design of Bearing type, fabricating cost is relatively costly, and effectively cannot reduce product cost, and this chain wheel carrier 40 drives this actuator 30 need lean on the screw thread of mutual snap-in to promote from axle rotation, but the material that both use is different, under using so long-time, the chain wheel carrier 40 of low hardness will inevitably produce abrasion, and the efficiency turned a wheel is not good, often must eliminate and change colored hub, very uneconomical.
Consult Fig. 2, in response to the problems referred to above, develop again another kind of ratchet flower-drum, as TaiWan, China patent announcement number No. M315660 " wheel hub of bicycle " novel case, described Bearing profile shaft is held and replaces with complete loose pearl profile shaft with low cost respectively and hold 50, and change this actuator 30 into one-body molded with this chain wheel carrier 40, and be all made by chrome-moly steel, thus, just solve the problem that Bearing profile shaft holds cost intensive, also solve between this chain wheel carrier 40 and this actuator 30 because of abrasion problems that unlike material causes.But, this creation also cannot meet light-weighted design requirement, actuator 30 on the contrary because being integrated adopts chrome-moly steel to make with chain wheel carrier 40 and makes product weight heavier, and to be formed in one part because of this actuator 30 and this chain wheel carrier 40, unsuccessfully just need one whole to scrap once any one crucial assembly position processes, extremely waste raw material.

This first end cap 7 screw lock in this first end 11, and abuts this first beautiful signature 511.
This second end cap 8 screw lock in this second end 12, and abuts the 3rd beautiful signature 611.
Before explanation rotation process of the present utility model, be noted that in the direction of following explanation all using Fig. 5 as reference benchmark.Of the present utility modelly be assembled into this axle 1 for axle center, sequentially each assembly be socketed on outside this axle 1, just can complete.After having assembled, can be carried out rotating from axle relative to this axle 1 with this second rolling group 52 by this first rolling group 51 by means of this housing 2, this free wheel base 3 can be carried out rotating from axle relative to this axle 1 with the 4th rolling group 62 by the 3rd rolling group 61, and this free wheel base 3 connects the structural relation of this housing 2 by this clutch unit 4, when rider drives the chain wheel carrier 32 of this free wheel base 3 along clockwise direction, this ratchet ring 41 is also driven and synchronously rotates along clockwise direction, now, utilize the meshing relation of described pawl 42 and described ratchet 411, can rotate along clockwise direction by this housing 2 of interlock, and then drive cycle wheel to rotate.On the contrary, when rider drives the chain wheel carrier 32 of this free wheel base 3 in the counterclockwise direction, this ratchet ring 41 is also driven and synchronously rotates in the counterclockwise direction, now, described pawl 42 meeting escape on described ratchet 411 respectively, and utilize the elastic force of described elastic component 43 that described pawl 42 is once more engaged with described ratchet 411 respectively after escape, that is this housing 2 is motionless and this free wheel base 3 dallies in the counterclockwise direction.
Accountablely be, in the present embodiment, in the composition assembly of this free wheel base 3 only this actuator 31 because of need with mutually contact and the friction for a long time of described pawl 42, so hardness need be adopted higher and the chrome-moly steel of heavier-weight makes, to guarantee product working life, different assembly (this chain wheel carrier 32 and this lock firmware 33) all can adopt hardness less and the aluminum alloy of lighter in weight is made in addition, because the belled part 321 of this chain wheel carrier 32 is by the respective outer side edges relation with the non-circular radial cross section of this embedding part 311 difference, and the effect reached without the need to adopting the material of high hardness just can bear high torsion, this lock firmware 33 is because only for this chain wheel carrier 32 of interlocking and this actuator 31, there is no the demand of high strength, so also without the need to using the material manufacture of high hardness.Thus, just light-weighted design requirement can fully be reached by above-mentioned.
In sum, complete loose pearl type design bearing is all adopted by this housings support unit 5 and this free wheel base support unit 6, and manufacture cost can be forced down, reach object with low cost, again by the 3rd pearl bowl 612, this chain wheel carrier 32 is separate the assembly manufactured with this actuator 31, and the object reducing the failed material loss rate of processing can be reached, in addition, all adopt hardness less by this chain wheel carrier 32 and this lock firmware 33 and the aluminum alloy of lighter in weight is made, and this chain wheel carrier 32 is rabbeted by non-circular structure with this actuator 31, and lightweight can be had and bear two advantages of high torsion, so really can the purpose of this utility model be reached.
As described above, be only embodiment of the present utility model, when can not limit the scope of the utility model enforcement with this, namely all simple equivalences done according to the utility model claims and description change and modify, and all still belong to scope of the present utility model.
