Abstract
Around the central axle fixing part, is the stator constituted by several permanent magnets. When current flows through the induction coils in inner wheel frame, inductive electric field is constituted to rotate inner wheel frame in outer wheel frame. In inner wheel frame, is a clutch ring which transmits the power of inner wheel frame to the driving wheel of retarding mechanism so as to drive outer wheel frame. Between the clutch ring and the driving wheel, a clutch part controls power transmission.
Description
The present invention relates to a kind of wheel driver, refer in particular to the wheel that a kind of central shaft does not rotate, the improvement of its arrangement of clutch, and with this device drive wheels method.
The central shaft locking that makes wheel rotate wheel hub that modal method is a wheel and wheel, and central shaft is hubbed on the vehicle frame by bearing, when ordering about the central shaft rotation with power, can drive wheel and rotate thereupon.Other has a kind of is method with the induction field drive wheels of wheel hub inside, this method is to make central shaft be fixed in vehicle frame and can not rotate, on central shaft, establish winding coil then and pass to electric current and become stator, can constitute rotor jointly with most permanent magnets that wheel hub rotates simultaneously in the wheel hub internal arrangement again, by the electric field that produces between stator and rotor, order about rotor rotation and drive wheel hub and rotate thereupon.This method of coming drive hub with the induction field in the wheel hub, a kind of electric wheel that Ya Te like flying company once developed, this method is because the heat that winding coil produced on central shaft is difficult for lost, if therefore the good radiating mode of neither one cooperates, this kind design certainly will can't make the wheel high speed rotating, or for long continuous running.Because high speed rotating need be supplied with a large amount of electric currents, and long-time running needs sustainable supply electric current, winding coil will produce high heat and may be burnt short circuit.This defective especially can continue the middle appearance of travelling of upward slope at vehicle, the winding coil of the stator on the central shaft, though accepted very large amount electric current, but vehicle wheel rotational speed is still slow, for the high heat that produces by winding coil, although be provided with fan and heat-dissipating fin in wheel face, come the air flows of assist wheel inside, but still can't distribute heat in right amount.This result makes the temperature of winding coil continue to rise, but is reduced on the contrary by the output strength of induction field.Another problem that this method exists is, when giving the winding coil of stator when not powering, silicon steel sheet in the winding coil will attract each other with epitrochanterian permanent magnet, this phenomenon is subjected to very big resistance when making wheel spin, that is in a single day the electric motor car of using conventional method when meeting the unexpected state that can not supply power to winding coil, push away wheel to be moved will seem especially painstaking.
The above-mentioned conventional art that comes drive wheels with induction field, so permanent magnet can't be located on the stator, relatively winding coil is located on the rotor in the wheel hub, be because how winding coil can obtain electric current very ideally in rotation, and there is no the difficulty of combination or fit on when making it to implement, as if can't obtain very desirable solution always, therefore winding coil is located at epitrochanterian idea and not realized ideally.
Adopt above-mentioned principle, it is good that designer of the present invention once designed a kind of heat radiation, be suitable at the urban district low speed driving, or the wheel that is more suitable for climbing than existing electric motor car and the method for drive wheels, and patent applied for (CN94115411.4).In this application case, the shortcoming that the design person provides a complete scheme to solve existing electric wheel such as forming commutator with a rotatable ring-type printed circuit formula conductive plate, makes the winding coil of outer shroud can obtain electric current etc.Also comprise unprecedented design even, that is, for wanting stator and rotor not to produce magnetic force, marquis sometimes disturbs, so the stator on the central shaft can be rotated together along with the rotor in the wheel hub where necessary, therefore the static part at stator and central shaft has an arrangement of clutch, stator is rotated or does not rotate.Above-mentioned application case is as arrangement of clutch stator not to be rotated with a Drum brake element, belongs to a kind of clutch mode with radial action control stator.
The object of the present invention is to provide a kind of new wheel driver and the method for this device drive wheels, the arrangement of clutch of this device can produce the axial action that is parallel to the wheel center axle, make in the induction field rotor can along with or do not rotate together along with the wheel frame of outer shroud, solving the heat that winding coil produced in the prior art is difficult for scattering and disappearing, wheel is run up or problem such as long-time continuous running, can more be applicable to simultaneously the low-speed motion wheel of up-hill journey, or the vehicle of low speed drivings such as bicycle and wheelchair.
