Dynamic, Planetary Gear Transmission active lateral stabiliser bar, but servo motor, when responding frequent, temperature rises fastly, causes servo electric
The permanent magnet of machine rotor demagnetizes, and output torque weakens, and anti-stall ability is poor.And vehicle in racing operating condition or passes through uneven road surface
When, stabilizer bar needs frequently response.So the active lateral stabiliser bar of servo motor driving has reliability and durability poor
Disadvantage, so that the popularization of active lateral stabiliser bar is more difficult.In addition, stabilizer bar needs to export large torque, it is huge with weight of contending with
Vehicle roll, therefore ZL201410066521.7 using planetary gear as transmission mechanism so that entirely organization volume it is huge,
And it is limited by the narrow chassis installation space of vehicle, this structure has significant limitation.
Summary of the invention

In order to achieve the above object, the technical solution adopted by the present invention are as follows: a kind of vehicle active of reluctance motor formula harmonic drive
Stabilizer bar, the difference is that: it include reluctance motor, harmonic speed reducer, connecting flange and stabiliser bar, the magnetic resistance electricity
Machine exports the wave producer of axis connection harmonic speed reducer, and the steel wheel of harmonic speed reducer is joined by left connecting flange and left stabiliser bar
It connects, reluctance motor stator is coupled by right connecting flange with right stabiliser bar.
Preferably, the reluctance motor is 12/8 pole structure.
Compared with prior art, the present invention having the following beneficial effects:
(1) present invention is driven, reluctance motor using the active lateral stabiliser bar of reluctance motor driving compared to servo motor
Without permanent magnet on rotor, will not frequently load starting because of motor and rapidly temperature rise lead to the defect of demagnetization, and step motion side
Formula controls simpler.Compared to hydraulic and magnetic rheology type active lateral stabiliser bar, the active lateral of reluctance motor driving is stablized
Lever system responds rapid, high sensitivity.
(2) present invention uses reluctance motor nonmagnetic steel design limitation, can be defeated to increase motor by lengthening the folded height of rotor
Torque out is conducive to promote in narrow chassis space so that motor outer diameter greatly reduces.And reluctance motor is double-salient-pole knot
Structure has stronger anti-stall ability, is highly suitable for the active lateral stabiliser bar more demanding to response speed and high-torque.
(3) due to harmonic speed reducer, tooth with engaging for tooth is face contact in transmission, in addition total number of teeth in engagement (overlapping system simultaneously
Number) it is relatively more, thus unit area load is small, under material and the identical situation of speed ratio, to be substantially exceeded by loading capability other
Transmission and small volume, therefore active lateral stabiliser bar of the invention is small in size, structure is simple, is highly suitable for installation space
In harsh vehicle chassis.In addition, harmonic speed reducer is as torque drive component, the number of teeth of engagement is more, error equalization, i.e., more
Tooth engagement mutually compensates effect to error, therefore high transmission accuracy.The flexbile gear gear teeth are made uniformly to move radially in transmission process,
Even if input speed is very high, the Relative sliding speed of the gear teeth is still extremely low, high-efficient so wheel odontotripsis is small, but due to engaging-in and
When nibbling out, the two sides of gear are all worked, thus without impact phenomenon, movement is steady, and vibration is effectively reduced.
(4) present invention, can be according to the defeated of information of vehicles and pavement behavior active accommodation stabiliser bar by reluctance motor driving
Torsion stiffness out stablizes the angle of heel of vehicle in target zone, so that compensating for traditional stabilizer bar can not constantly adjust
The deficiency of the anti-roll stiffness of vehicle improves the stability and comfort of vehicle.
