The functions such as four-wheel steering, torque vector control, and wheel hub motor electric car eliminates transmission mechanism, drastically increases work
Efficiency, it can be seen that wheel hub motor electric car is with the obvious advantage compared with orthodox car more than, becomes electric car of future generation
Developing direction.
The brakes of conventional truck is generally X matched tube structures, when brakes breaks down, the front and rear system to side wheel
Dynamic device fails simultaneously, but the front and rear opposite wheel that brakes does not fail, and the front wheel brake power of generation is generally higher than trailing wheel
Brake force, so that sideslip can be produced to car body moment of torsion, vehicle.King pin offset is typically designed as negative value, forms a braking
The arm of force of power, brake does not have the brake force and the above-mentioned arm of force one reverse steering torque of formation of failure wheel, makes wheel to system
Dynamic device failure wheel side is turned to, and can offset the sideslip of above-mentioned car body.
The each wheel of wheel hub motor vehicle, can during if there is braking system faults by a motor independence drive control
Using left and right wheels Motor torque size is controlled, to produce corresponding steering torque to stablize the traveling of vehicle.
In addition, the most important, the driving force effect of traditional vehicle is at core wheel, but the driving of In-wheel motor driving wheel
Power is acted at tire earth point, and brake force is acted also on tire earth point, when king pin offset is set into 0, driving force
Moment of torsion will not be produced to deflecting roller with brake force, even if there is left and right wheels Motor torque not in vehicle traveling or braking procedure
State also can guarantee that the stability of vehicle in a balanced way.
In addition, will not in the case of left and right wheels Motor torque identical when wheel hub motor vehicle king pin offset is 0
Extra moment of resistance is produced, reduces motor and each part stress of suspension system, reduces loss.
For this technical field, domestic and international major Automobile Enterprises have carried out numerous studies, and such as MIT proposes
" wheel hub motor " (JP 2006199107) and BYD joint-stock company propose a kind of entitled " wheel hub motor of utility model
