Abstract

The invention discloses a power transmission system of an all-wheel-drive hybrid power car. The power transmission system comprises a front drive system and a rear drive system. The front drive system comprises an engine, a generator and a front drive motor, wherein the engine is in transmission connection with the generator, a power output side of the engine and a power output side of the front drive motor are connected through a clutch, and an output side of the front drive motor is in drive connection with front wheels. The rear drive system comprises a rear drive motor used for driving rear wheels. The front drive system and the rear drive system of the power transmission system carry out drive independently, a power divider is not needed, and the structure of the transmission system is simplified. In the front drive system, the power of the engine and the front drive motor is switched on and off through the clutch, and after disengagement of the clutch, the idling stop function of the front drive system can be realized. The invention further discloses the all-wheel-drive hybrid power car comprising the power transmission system.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a power transmission system of a four-wheel drive hybrid electric vehicle. It also relates to a four-wheel drive hybrid vehicle including the power transmission system. Background technique [0002] With the global energy shortage and the intensification of environmental problems, various automobile companies are facing severe challenges. Energy-saving and emission-reducing hybrid electric vehicles have become the focus of automobile companies and related research institutions in various countries. [0003] Under the influence of resources, market positioning, technical route, etc., and catering to the needs of drivers, the world's major automakers have adopted some different hybrid systems and developed four-wheel drive hybrid systems. US Patent No. 6,484,834B2 discloses a hybrid four-wheel drive configuration, which adopts two power lines of front drive and r...
