By technique scheme, described diverter is arranged on the colored hub of rim, is coaxially disposed with rim.
By technique scheme, on rim, the both sides of respective rotor winding are provided with Circular Winding protection lid.
By technique scheme, vehicle frame is additionally provided with the guide wheel assembly preventing rim from skew occurring.
By technique scheme, described rotor windings includes organizing winding more, and often group winding embeds in the position, hole that rim is reserved in advance after making.
By technique scheme, described Magnet is arranged on the upper extreme direction of rim.
By technique scheme, the often group curved distribution of Magnet, the central angle of its correspondence is 30 °～120 °.
By technique scheme, often group Magnet is made up of polylith heteropole Magnet, and each heteropole Magnet is alternately arranged in the mode that circumferential direction is N-S.
By technique scheme, described power supply is rechargeable type power supply.
Having the beneficial effect that acquired by this utility model
1, this utility model is by being arranged on rim by rotor windings, is fixed on vehicle frame by Magnet, and winding is between two groups of Magnet, the magnetic field intensity making winding place is very big, and therefore, the moment of torsion at rim place is very big, operational efficiency significantly improves, and auxiliary grade climbing performance is good；It addition, the relatively existing drive system of this utility model, Magnet quantity used reduces, and cost greatly reduces, practical；
2, the region only covered by Magnet in whole circle winding is in running order, and remainder is in radiating state, therefore, its perfect heat-dissipating, highly reliable；
3, this utility model iron-core-free winding, it does not have slot effect, can guarantee that bicycle coasting is smooth and easy；
4, this utility model iron-core-free winding is lightweight, the weight that tradition rim increases is compared few equipped with the rim of this winding, and rim radius is sufficiently close to radius of wheel, make this cover system just need not can obtain powerful driving force by deceleration device, decrease actuating device, make simple in construction, decrease volume and weight；Due to without drive system so that this cover system freely can switch between two kinds of mode of operations of driving and generating, practical；
5, this cover system can be installed on the basis of tradition bicycle and man, and reduce the amendment to primary car structure to greatest extent, both the light beautiful advantage of standard bicycle had been kept, the standard bicycle production technology of maturation can be utilized again, make to be substantially reduced equipped with the electric bicycle production cost of this drive system.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-5, present embodiments provide the driving device of a kind of electric bicycle, including mover assembly, stator module, diverter 4, brush 5, power supply, described mover assembly includes rim 1 and along the circumferentially disposed rotor windings 3 of rim 1, wherein, rotor windings 3 includes organizing winding more, and often group winding embeds after making in advance in the position, hole that rim is reserved and then uses poured with epoxy resin, and winding connection mode is as shown in Figure 5.Stator module includes the 2 groups of Magnet 2 that pole is arranged arranged in rim 1 both sides, and often group Magnet is curved layout, and the central angle of its correspondence is 30 °～120 °, it is preferable that 80 °.Often group Magnet is made up of polylith heteropole Magnet (being namely made up of N pole and S pole), each heteropole magnetic piece is fixed on curved stainless steel plate 8, each heteropole Magnet is alternately arranged in the mode that circumferential direction is N-S, as shown in Figure 6, certain group of magnets of the present utility model can also adopt other arrangement mode to magnetic piece arrangement mode.Described often group Magnet 2 is fixed on vehicle frame (wherein vehicle frame and bracing frame all do not illustrate in the drawings) by bracing frame, and described rotor windings 3 is arranged between 2 groups of Magnet, and and is provided with gap between Magnet 2.Described diverter 5 is installed on the colored hub 6 of rim, is coaxially disposed with rim 1, rotates with rim simultaneously, and diverter 5 is connected with rotor windings 3.Brush 4 is fixed on vehicle frame by bracing frame, and brush 4 has two carbon brush, is connected with power positive cathode respectively, and each carbon brush arranges with diverter 5 phase.Wherein, power supply is the set of cells that 10 joint 3.6V chargeable lithium cells are composed in series, and maximum voltage is 36V with speed regulator, it is possible to reduce output voltage.It addition, the both sides of respective rotor winding 3 are provided with Circular Winding protection lid 8 on rim 1, it is prevented that rim deflection is excessive causes that Magnet scrapes winding.
During work, the part winding that electric power outputting current is connected in rotor windings 3 in Magnet coverage with diverter 5 by brush 4, make charged rotor windings 3 be subject to Ampere force in magnetic field and drive rotation of wheel.And the winding not covered by Magnet does not work, this contributes to heat radiation and power saving.By changing electric power output voltage, thus it is possible to vary the power of wheel.When vehicle is in coast, whole device can become generating state, it is possible to makes power supply be in charged state, when deenergization, will not generate electricity, also not by the impact of slot effect, device can art skating, practicality is very strong.
In the present embodiment, it is also possible to be additionally provided with the guide wheel assembly (not shown in the figures anticipate out) preventing rim from skew occurring on vehicle frame.
This utility model is applied widely, it is possible to be applied on bicycle and man, pure driven by power bicycle, single wheel electrodynamic balance car, does not tire out one by one at this and states.
