An integrated drive system that includes a motor having a housing and an output shaft is disclosed. The integrated drive system further includes a planetary gear transmission mechanism having a first-stage planetary gear mechanism and a second-stage planetary gear mechanism. The first output torque of the first-stage planetary gear mechanism is transmitted to a driven object. The second output torque of the first-stage planetary gear mechanism is transmitted to the second-stage planetary gear mechanism. And the third output torque of the second-stage planetary gear mechanism is transmitted to the driven object. An electric vehicle that includes the described integrated drive system is also disclosed.

Integrated drive system and electric vehicle

An integrated electric drive system includes an electric machine having a first housing and an output shaft, a transmission having a second housing and a drive shaft, and a power electronics module with a third housing and an electronic device configured to provide electric power for the electric machine. The transmission receives an input torque of the output shaft and outputs the same via the drive shaft. The power electronics module is configured to be arranged around the drive shaft. The integrated electric drive system can be installed on an electric vehicle. The integrated electric drive system has a more compact structure with a higher degree of integration, and better heat dissipation capability, facilitating spatial optimization and lightweight design of the electric vehicle.

Integrated electric drive system and electric vehicle

A driving system for an electric vehicle comprises a motor () comprising a first output shaft () and a gearbox () comprising a second output shaft () attachable to a wheel () of the electric vehicle. The first output shaft () is capable of driving the second output shaft () to rotate by engagement of gears of the gearbox (). The first output shaft () is hollow, and the second output shaft () extends through the first output shaft () so that the second output shaft () is disposed coaxially with the first output shaft (). An electric vehicle comprising the driving system is disclosed. The driving system is possible to improve the balancing, the passing ability and the visual appearance of the electric vehicle.
