Problems solved by technology

However, this layout still has disadvantages. For example, when the power electronics module is arranged on one side of the drive shaft of the gearbox, the space on this side limits the size of the power electronics module, which affects the arrangement of electronic devices in the power electronics module. and heat dissipation, while the space on the other side of the drive shaft is not used, resulting in a waste of space

Abstract

The present application provides an integrated electric drive system, comprising: a motor comprising a first housing and an output shaft, a gearbox comprising a second shell and a driving shaft, and apower electronic module; the gearbox receives the input torque of the output shaft and outputs the input torque through the driving shaft; the power electronic module comprises a third shell and an electronic device, and the electronic device is configured to provide power for the motor; and the power electronic module is configured to be arranged around the driving shaft. In addition, the application further provides an electric vehicle comprising the integrated electric drive system. The integrated electric drive system has a more compact and higher-integration-level structure and higher heat dissipation capacity, and space optimization and lightweight design of the electric vehicle are facilitated.

Description

technical field [0001] The present application relates to the technical field of vehicle drive, and in particular to an integrated electric drive system and an electric vehicle including the integrated electric drive system. Background technique [0002] With the emphasis on energy crisis and environmental pollution and the development of electric drive technology, more and more vehicles are powered by on-board power supply, through the electric drive system (eAxle, also known as "electric drive axle" or "electric bridge") etc.) to drive the vehicle. An electric drive system is generally a power drive assembly that integrates an electric motor, a gearbox, and a power electronics module (for example, an inverter). This integrated electric drive system has obvious advantages in improving power density, reducing the number of parts, shortening the length of high-voltage cables and compact structure. [0003] In the existing integrated electric drive system, the housing of the...
