Abstract

The invention discloses an integrated power transmission system for an electric vehicle, which includes a drive axle housing, an electric motor and half shafts symmetrically installed on the left and right sides of the housing; a differential and a transmission shaft for power input are installed in the housing , the transmission shaft is connected to the planetary gear carrier of the differential through the gear transmission mechanism, and is used to drive the planetary gear carrier to rotate in the housing; the transmission shaft is arranged along the axis perpendicular to the planetary gear carrier, and the housing has an end face with the motor. Matching flange surface, the flange surface is perpendicular to the axis of the transmission shaft, the motor is installed on the flange surface, and the output end of the motor is coaxially connected to the transmission shaft. The invention has compact structure, small volume, easy installation, can eliminate the gap between the motor and the bridge body, is not easy to get water, and has a high waterproof level; it is beneficial to reduce the weight of the whole vehicle, increase the cruising range, reduce the power transmission structure, and simplify Manufacturing process and installation process.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle power transmission integrated system. Background technique [0002] With the rapid development of science and technology, the penetration rate of automobiles is getting higher and higher. While automobiles provide convenience for people's lives, they also cause serious pollution to the atmospheric environment. For this reason, the requirements for automobile exhaust emissions are also increasing. high. Both pure electric vehicles and hybrid vehicles can be powered by the on-board power supply, and use the motor to drive the wheels, which is beneficial to reduce fuel consumption, has the advantages of energy saving, low emissions, etc., and has gradually become the trend of future automobile development. [0003] In recent years, small electric trucks have become more and more popular with small businesses because of their economical and practicality...
