All have gear ring between described two slip cap outer rims and the described axle sleeve inner edge, all connect by one-way clutch between the outer rim of two gear rings and the inner edge of axle sleeve, an end of two gear ring inner edges all has interior ratchet, and the other end all has internal tooth;
One end of described two slip cap outer rims all has at least two holes, and the unidirectional ratchet that can eject all is installed in the hole;
Each outer rim in abutting connection with described power wheel one end of described two slip caps comprises at least 1 facet, and each comprises at least 1 facet two power wheels in the centre hole of slip cap one end, and slip cap outer rim and facet are slightly less than power wheel inner edge and facet;
Has boss in the described two slip cap centre holes, boss is to equal mounting spring on the described wheel shaft between the bearing ground, the wheel shaft two ends are positioned at slip cap centre hole ground and respectively comprise the bar shaped open-work, slidably block all is housed in the open-work, two blocks grow wheel shaft show the part just can push the boss of institute's adjacency separately;
Described wheel shaft two ends have Kong Xin, and the hole in-core is equipped with adjusts rod, and the described hole core degree of depth just can allow described adjustment rod push described block and slide.
Described wheel shaft faces and connects described bearing both sides ground and respectively have a circle tooth, respectively has at least more than one planetary wheel around described tooth, and described planetary wheel is meshed with the internal tooth of described gear ring;
Described planetary wheel all is installed on support, and described support has interior ratchet in abutting connection with a side of described slip cap;
When vehicle ' left and right sides pedal is stepped on, left and right sides sprocket wheel drives left and right sides chain and drives the left and right sides each spinning of power wheel, the ratchet that can mesh gear ring by the ratchet of slip cap and ejection drives the gear ring rotation, and gear ring can and drive wheel revolutions by one-way clutch driven wheel axle sleeve again; When the vehicle axle sleeve desire that need fall back forces slip cap when counter-rotating by ratchet and ratchet, be subjected to the outer control of handling, the adjustment rod has deeply promoted link stopper and has promoted slip cap again, makes slip cap drive ratchet and leaves the ratchet of gear ring, thereby reached the purpose of utilizing neutral conveniently to fall back; When needing variable block to quicken in the vehicle ', be subjected to the outer control of handling, adjust the more deep promotion block of rod and promoted slip cap again, make ratchet and support ratchet engagement, make support force planetary wheel on axle tooth, to rotate and pass through and drive the faster rotation of gear ring with the engagement of gear ring internal tooth, and gear ring has driven axle sleeve and wheel fast rotational by one-way clutch, thereby has reached more convenient and quicker, labour-saving purpose more.
The beneficial effects of the utility model are, simple in structure, easy fitting operation, not only can be when vehicle fall back, pedal, wheel disc, chain is no longer followed reversing, bring great convenience to the cyclist, also be suitable for the double-stranded bicycle hub internal speed-changing that drives fully, allow the cyclist feel lighter, more laborsaving.

The specific embodiment
In Fig. 1,
Connect by bearing (3) between the stage casing in the axle sleeve (1) and the stage casing of wheel shaft (2);
Each all connects power wheel (4) by bearing (3) in abutting connection with ground, axle sleeve (1) two ends wheel shaft (2) two ends;
Face on the wheel shaft (2) in the axle sleeve (1) and all have slip cap (5) with connecing two power wheels (4);
All has gear ring (6) between two slip caps (5) outer rim and axle sleeve (1) inner edge, all connect between the inner edge of the outer rim of two gear rings (6) and axle sleeve (1) by one-way clutch (7), one end of two gear rings (6) inner edge all has interior ratchet (8), and the other end all has internal tooth (9);
