Three-clutch electromechanical coupling driving device for motor vehicle

Abstract

The invention discloses a three-clutch electromechanical coupling driving device for a motor vehicle. The three-clutch electromechanical coupling driving device comprises a shell body, a front end cover, a motor, an input shaft, a rotor support, a supporting shaft, a cut-off clutch and a double clutch. The motor is provided with a rotor and a stator. The cut-off clutch and the double clutch are integratedly arranged inside the motor. The rotor is connected with the rotor support connected with the supporting shaft. The left end of the supporting shaft is supported on an even-number gear output shaft of the double clutch through a bearing. The even-number gear output shaft of the double clutch is supported on an odd-number gear output shaft of the double clutch through a bearing. The odd-number gear output shaft of the double clutch is supported on the shell body through a bearing. The right end of the supporting shaft is supported on the input shaft through a bearing set. The input shaft is supported on the front end cover through a ball bearing. The three-clutch electromechanical coupling driving device has the beneficial effects of being small in axial size, small in part number, low in cost and high in precision.

Description

technical field [0001] The invention relates to a three-clutch electromechanical coupling driving device for a motor vehicle, in particular to a transmission for a hybrid vehicle. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in the world continues to rise, and the problems of energy consumption and environmental pollution caused by automobiles are becoming increasingly apparent. In response to increasingly stringent automotive fuel consumption and emission regulations, all auto companies have focused on energy-saving and emission-reduction technology research and development. Hybrid vehicles are gradually emerging in the market due to their technical and cost advantages, and have become the mainstream development of the automotive industry. trend. [0003] With the development of hybrid electric vehicles, there is an urgent need for a transmission that provides a better electromechanical coupling solution to ...

Problems solved by technology

[0004] In the existing electromechanical coupling transmission scheme, the separation clutch and the double clutch are independent assemblies arranged separately. The consequence of this arrangement is that the axial size of the transmission is too large, the layout of the whole vehicle is difficult, the number of parts is large, the cost is high, and the assembly process is difficult. poor sex
