Abstract

The invention relates to a hybrid drive system and a vehicle. The system comprises an engine, a first motor, a transmission and an output part; a power shaft of the first motor is coaxially connectedwith an output shaft of the engine; the transmission is located between the engine and the first motor and comprises a double clutch, a first gear set and a second gear set, an output shaft of the engine is connected with an input end of the double clutch, a first output shaft of the double clutch is connected to the first gear set, and a second output shaft of the double clutch is connected to the second gear set; the output part is used for outputting power transmitted by the first gear set or the second gear set so as to drive the vehicle.

Description

technical field [0001] The present disclosure relates to a hybrid drive system and a vehicle. Background technique [0002] In today's world, human beings are facing two major challenges: energy scarcity and environmental degradation. Traditional automobiles are increasingly plagued by the oil crisis. Energy conservation and environmental protection have gradually become the development theme of the automobile industry. In recent years, hybrid electric vehicles with two different power sources to achieve reduced fuel consumption and emissions have been developed and applied, and put into commercial production and introduced to the market. [0003] A hybrid drive system is generally composed of an engine, a generator, an electric motor, and a power supply. The engine and the power supply jointly provide power for the vehicle, which results in a complex structure, a large space occupation, and a high cost. Contents of the invention [0004] The purpose of the present disclo...
