Description
Technical field
The present invention relates to around the magnet technology field of armature rotation, more particularly, to a kind of easy to use, control sensitive
Electromagnetic force wheel hub motor.
Background technology
Also known as wheel inner electric machine technology, its maximum feature is exactly by power, transmission and braking dress to wheel hub motor technology
Put and be all incorporated in wheel hub, therefore the mechanical part of electric vehicle is greatly simplified.Wheel hub motor technology not new things, early
In 1900, Porsche was just manufactured that front-wheel equips the electric automobile of wheel hub motor, in 20 century 70s, this skill first
Art is applied in fields such as Mine haul cars.And for the wheel hub motor used by passenger car, Japanese manufacturer is for technique
Research and development are carried out relatively early, are currently in leading position, and the international automobile giant including general, Toyota is also to this technology
Set foot in.Domestic Ye You independent brand automobile vendor starts to research and develop technique at present, the Riich put on display in Shanghai car exhibition in 2011
X1 increases journey electric motor car and just employs wheel hub motor technology.
In-wheel motor driving system is largely divided into two kinds of structural shapes: inner-rotor-type and outer turn according to the rotor type of motor
Minor.Wherein external-rotor-type adopts low speed unofficial biography sub-motor, and in 1000-1500r/min, no slow down the maximum speed of motor dress
Put, the rotating speed of wheel is identical with motor；And inner-rotor-type then adopts high speed inner rotor motor, it is equipped with the deceleration of fixed drive ratio
Device, for obtaining higher power density, the rotating speed of motor may be up to 10000r/min.With more compact planetary gear speed-reduction
The appearance of device, inner-rotor-type wheel hub motor is more more competitive than low speed external-rotor-type in terms of power density.
But existing wheel hub motor there is also many shortcomings:
Shortcoming 1: increase the rotary inertia of unsprung mass and wheel hub, the manipulation on vehicle has affected.For normal domestic
For vehicle, usually make the part of suspension with the material such as aluminium alloy of some relative lightweight, to mitigate unsprung mass, carry
Rise the response speed hanging.But wheel hub motor greatly increases unsprung mass just, also increases wheel hub simultaneously
Rotary inertia, this is unfavorable for the handling of vehicle.But mostly it is limited to ride instead of walk rather than pursue in view of electronic vehicle
Power performance, this point is not already greatest drawback.
Shortcoming 2: electric braking limited capacity, maintaining brakes to run needs to consume many electric energy.Present traditional power
Commercial car has had the assisted deceleration equipment being much equipped with using eddy-current brake principle (namely resistive braking), such as much blocks
Electronic retarder used by car.And the relation due to the energy, electric motor car is also first-selected using electric braking, but for wheel hub motor
Drive vehicle, due to the electric braking capacity of wheel hub motor system less it is impossible to meet the requirement of braking performance of vehicle, be required for
Additional mechanical brakes, but for common electric passenger car, the vacuum pump that drives without traditional combustion engine is it is necessary to electricity
Dynamic vacuum pump is providing brake power-assisted, but has also just meaned bigger energy expenditure, and even regenerative braking energy reclaims one
A little energy, if the efficiency of brakes to be guaranteed, the energy of brakes consumption is also the weight of impact electric motor car course continuation mileage
Want one of factor.
Additionally, the bad environments of wheel hub motor work, face many-sided impact such as water, dust, also have relatively in seal aspect
High request, is also required to individually consider heat dissipation problem for wheel hub motor simultaneously in design.Compared with concentrating power drive with motor,
Wheel hub motor technology possesses very big advantage, its layout more flexible it is not necessary to the machine driven system of complexity, also have simultaneously from
Oneself notable deficiency, the such as equilibrium relation between sealing and breakaway starting current/moment of torsion, and differential problem of driving wheel etc. when turning to
Deng if these difficult problems can be solved in engineering, In-wheel motor driving technology is wide by having in following new forms of energy car
Prospect.
