In order to achieve the above object, the invention provides a kind of quick-disassembly structure of internal speed variator of bicycle anchor shaft, this internal speed changer is fixedly assembled on internal speed changer anchor shaft, the outside of internal speed changer is the rotatable wheel hub of hiding internal speed changer, and utilize this internal speed changer anchor shaft to coordinate device for quickly disassembling to be fixed on vehicle frame, wherein the axle center of internal speed changer anchor shaft is the penetrating via that a cooperation device for quickly disassembling runs through.
This internal speed changer anchor shaft outside is provided with at least one inner concave shape strengthening rib extended along axial indent.
This internal speed changer anchor shaft outside is provided with at least one convex-type strengthening rib extended along axial evagination.
After adopting such scheme, the present invention has the following advantages:
1, provide a kind of internal speed changer anchor shaft quick-disassembly structure being common to no chain drive bike and chain gear bicycle, make monotechnics create the internal speed changer that can be widely used in no chain drive bike and chain gear bicycle;
2, the advantage of saving space and alleviating overall weight is effectively reached;
3, reduce industry cost, promote overall industry and produce effect;
4, the effective reduced proper motion car internal speed changer dismounting operation that combines with vehicle frame or be separated, the vertical and maintenance efficiency of lifting group, and then raising industrial economy benefit;
5, be provided with the internal speed changer anchor shaft of penetrating via by axle center, reach single internal speed changer anchor shaft produce internal speed changer and wheel hub combines and with the fast assembling-disassembling benefit of vehicle frame.
