1), can trouble-freely bear and transmit all force and moments of wheel.
2), transitional function can be played by the structure space between motor point and Wheel bearing.
3), must can support wheel bearing, brake clamp and elastic support.
In addition, rear drum support can also support sensor and cleading, it is gone back the guide groove that accessible site has oil pipe and linear speed.
There is following problem in existing rear rear drum support:
1), complex structure, increase casting difficulty.
2), complicated structure easily causes stress to concentrate in Ge Bian intersection.
3), discontinuity.
