In order to solve above technical matters, the utility model provides a kind of double wishbone suspension wheel limit power drive system, comprises wheel rim, wheel hub, hub bearing, stub, large bearing, axle drive shaft, Top Crossbeam, driven large belt wheel, Timing Belt, lower cross arm, little bearing, little bearing brackett, active small pulley, motor and vehicle frame.Integrated driven unit is fixed on vehicle frame, between active small pulley in integrated driven unit and driven large belt wheel, by Timing Belt, be connected transferring power, driven large belt wheel and double wishbone suspension structure form integral structure, driven large belt wheel is connected transferring power by spline with axle drive shaft, axle drive shaft and wheel hub adopt spline joint, wheel hub is supported on stub by hub bearing, and wheel hub is bolted transmission of power to wheel rim.
Described double wishbone suspension structure comprises upper and lower transverse arm and stub, and wherein place, the nearly wheel rim of upper, lower horizontal arm rest one end is connected with stub by ball pivot, and the upper and lower transverse arm other end is connected with vehicle frame by ball pivot, and axle drive shaft is supported in stub by large bearing.
Described integrated driven unit comprises motor, active small pulley, little bearing and little bearing brackett, and initiatively small pulley is installed and is supported in little bearing brackett by little bearing, and little bearing brackett is connected with motor by bolt.Integrated driven unit becomes a part for spring carried mass, has reduced to a great extent nonspring carried mass.
Described driven large belt wheel and axle drive shaft are fixed by back-up ring by spline joint and with the axial side of axle drive shaft, and opposite side is fitted with large bearing medial surface.So driven large belt wheel and double wishbone suspension structure form integral structure.
During due to bob under the effect of wheel at random road excitation, driven large belt wheel also can swing with the stub of double wishbone suspension structure, and now driven large belt wheel can change with the width between centers of active small pulley, and has certain torsion.Therefore utilize the advantage of Timing Belt Flexible Transmission in the utility model, be that width between centers has certain variable range, by theory, calculate selected suitable double wishbone suspension parameter, make wheel leaning angle and wheelspan in its suspension hopping process change less, driven large belt wheel and the width between centers of active small pulley are changed in the tolerance interval of belt wheel tensioning, suitable step-down ratio is set simultaneously and can plays the effect that the increasing of slowing down is turned round.
Brake system of the present utility model can adopt disc type brake or drum brake.
The utility model can be used for the wheel limit electric drive of non-wheel flutter, when back-wheel drive, can completely use.
Superior effect of the present utility model is:
(1) adopt wheel limit power drive system structure, two transverse arm stubs connect driven large belt wheel simultaneously, and integrated degree is high;
(2) the integrated drive elements such as drive motor and active small pulley are fixed on to vehicle frame, thereby have reduced to a great extent nonspring carried mass, improved ride comfort and the wheel ground connection property of automobile;
(3) deceleration increasing is turned round transmission and is adopted Timing Belt Flexible Transmission form, has advantages of that width between centers is variable;
(4) select toothed belt transmission, with respect to gear transmission, to sealing and lubricating requirement, reduced many.
