fig. 1 is the structural representation of a specific embodiment of the present invention.
In accompanying drawing, the corresponding name of Reference numeral is called: 1, motor, 2, wheel carrier, 3, air bag, 4, top link, 5, shock absorber, 6, lower swing arm.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is done to detailed description further, but embodiments of the present invention are not limited to this.
Embodiment 1:
As shown in Figure 1, independent suspension wheel limit power drive system, comprise motor 1, wheel carrier 2, top link 4 and lower swing arm 6, wherein, motor 1 is fixed on wheel carrier 2, top link 4 and the equal one end of lower swing arm 6 are connected on wheel carrier 2, and the connecting portion of top link 4 and lower swing arm 6 and wheel carrier 2 lays respectively at the two ends up and down of wheel carrier 2.The single wheel that is used for driving electronic class new forms of energy bus during the present embodiment application, motor 1 outputs power to and on wheel hub, realizes driving wheel, the quantity of the required the present embodiment of each new forms of energy bus is a plurality of, laying respectively at two drive systems corresponding to new forms of energy bus both sides and position connects by support, when concrete connection, the drive system of the present embodiment is connected on support by top link 4 and lower swing arm 6.
