Description
Technical field
The present invention relates to the magnet technology field around armature rotation, relate in particular to a kind of easy to use, control sensitive electromagnetic force wheel hub motor.
Background technology
Wheel hub motor technology claims again wheel inner electric machine technology, and its maximum feature is all incorporated into power, transmission and brake apparatus in wheel hub exactly, therefore the mechanical part of motor vehicle is simplified greatly.Wheel hub motor technology is not new things, and as far back as 1900, first Porsche just produced the electric automobile of front-wheel equipment wheel hub motor, and at 20 century 70s, this technology is applied in fields such as mine transport vehicles.And for passenger car wheel hub motor used, Japanese manufacturer carries out early for technique research and development, maintain the leading position at present, also all have related to this technology including the international automobile giant general, Toyota.Current domestic Ye You independent brand automobile vendor starts to research and develop technique, and the Riich X1 putting on display Shanghai car exhibition in 2011 increases journey electric motor car and just adopted wheel hub motor technology.
In-wheel motor driving system is mainly divided into two kinds of structural shapes according to the rotor type of motor: inner-rotor-type and external-rotor-type.Wherein external-rotor-type adopts low speed unofficial biography sub-motor, and the maximum speed of motor is at 1000-1500r/min, and without deceleration device, the rotating speed of wheel is identical with motor; Inner-rotor-type adopts high speed inner rotor motor, is equipped with the decelerator of fixed drive ratio, and for obtaining higher power density, the rotating speed of motor can be up to 10000r/min.Along with the appearance of more compact planetary reducer, inner-rotor-type wheel hub motor is more competitive than low speed external-rotor-type aspect power density.
But also there are many shortcomings in existing wheel hub motor:
Shortcoming 1: increase the moment of inertia of unsprung mass and wheel hub, the manipulation of vehicle is affected to some extent.For normal domestic vehicle, usually with the material of some relative lightweights such as aluminium alloy is made the parts of suspension, to alleviate unsprung mass, promote the response speed hanging.Wheel hub motor has increased unsprung mass just greatly, has also increased the moment of inertia of wheel hub simultaneously, and this handling for vehicle is disadvantageous.But consider that electronic vehicle is limited to mostly and ride instead of walk but not pursue power performance, this point is not still greatest drawback.
Shortcoming 2: electric braking performance is limited, maintains braking system operation and need to consume many electric energy.Present traditional power commercial car has had many assisted deceleration equipment that utilizes eddy current braking principle (being also resistance braking) of having equipped, such as a lot of truck electronic retarders used.And due to the relation of the energy, it is also first-selected that electric motor car adopts electric braking, but for the vehicle of In-wheel motor driving, because the electric braking capacity of wheel hub motor system is less, can not meet the requirement of braking performance of vehicle, all need additional mechanical braking system, but for common electric passenger car, the vacuum pump that has not had traditional combustion engine to drive, just need electric vacuum pump that brake power-assisted is provided, but also just mean and had larger energy consumption, even if regenerative braking energy reclaims some energy, if guarantee the usefulness of braking system, the energy of brake system consumes is also one of key factor affecting electric motor car course continuation mileage.
In addition, the environment of wheel hub motor work is severe, faces many-sided impact such as water, dust, also has higher requirements at seal aspect, also needs in design to consider separately heat dissipation problem for wheel hub motor simultaneously.Compared with concentrating power drive with motor, wheel hub motor technology possesses very large advantage, its layout is more flexible, do not need complicated machine driven system, also have own remarkable deficiency simultaneously, such as seal and breakaway starting current/moment of torsion between equilibrium relation, and the differential problem etc. of driving wheel while turning to, if can solve these difficult problems in engineering, In-wheel motor driving technology will be gathered around and hold out broad prospects in following new forms of energy car.
