Hybrid power drive system based on double-clutch transmission

The invention provides a hybrid power drive system based on a double-clutch transmission, relating to the technical field of machines and solving the problems of too many parts, large volume, complex structure and difficult configuration of the traditional hybrid power drive system. The hybrid power drive system based on a double-clutch transmission comprises an engine, a motor and a double-clutch automatic transmission which is connected with a differential mechanism disposed on a rotating shaft, wherein the output shaft of the engine is connected with the input end of the double-clutch automatic transmission, the motor is integrated on the double-clutch automatic transmission, and the output shaft of the motor is connected between the double-clutch automatic transmission and the differential mechanism through a gear transmission mechanism. The invention has the advantages of compact structure, small axial size, convenient installation, easy layout and high transmission efficiency.
