Abstract

The invention belongs to the technical field of vehicle transmissions, and provides a hybrid power driving system and a vehicle, the hybrid power driving system comprises an engine, a motor, a transmission and a differential assembly, the transmission comprises a single clutch, double clutches and a transmission gear train, the double clutches comprise an even-number-gear clutch and an odd-number-gear clutch, and the transmission gear train is connected with the single clutch. The motor and the double clutches are integrated in the transmission gear train, and the transmission gear train comprises a transmission input shaft assembly, a first output shaft assembly, a second output shaft assembly and a synchronizing device. According to the hybrid power driving system, the motor and the double clutches are integrated in the transmission gear train of the transmission, the axial space size of the transmission is greatly optimized, and therefore a larger motor can be selected, and the dynamic property of the whole vehicle is guaranteed. The motor and the double clutches are integrated in a transmission gear train of the transmission and can be forcibly cooled and lubricated through an oil duct, and it is guaranteed that the double clutches and the motor have good heat resistance.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmissions, in particular to a hybrid drive system and a vehicle. Background technique [0002] The hybrid system generally has two types: a single-motor parallel hybrid system, a dual-motor parallel or a hybrid hybrid system. [0003] The development cost of the existing dual-motor parallel or hybrid hybrid system is high, the transformation of the traditional power system is large, and the control of the hybrid system is more difficult. [0004] In the existing single-motor parallel hybrid system, the motor is integrated on the input or output shaft of the transmission to realize the hybrid output of the two powers. However, the required axial space is large and the powertrain needs to be rearranged. When the engine and motor power are switched and intervened, shocks will occur, affecting drivability. The motor cannot function as a starter, and cannot realize the start-stop function of the...
