Abstract
The utility model relates to a rear axle for electric vehicle, which uses a high-speed direct-current motor as a power for driving the vehicle through large ratio speed reduction. The rear axle comprises a gearbox body as a framework. The direct-current motor is fixed on the gearbox body. The power output by the direct-current motor is transmitted to a primary speed reduction planet device. Then the power is transmitted to a secondary speed reduction planet device on a same shaft by the primary speed reduction planet device through a pinion shaft of the gearbox. Then the power is transmitted to a final transmission driving gear on the same shaft through the secondary speed reduction planet device. Finally the power is transmitted to a girth gear on a differential. The girth gear then drives a differential assembly. Thus the large ratio speed reduction is completed and the torque is increased. Then an axle shaft gear drives a semiaxis, a wheel spider, a steel ring and tyres for driving the vehicle. The rear axle for electric vehicle according to the utility model has the advantages of small volume, large reduction ratio, large torque, strong closeness property, sufficient lubrication, low fault rate and reasonable fabricating cost.
