Abstract

The invention provides a four-drive vehicle hybrid power system. The four-drive vehicle hybrid power system comprises an engine, a first clutch, an engine power input shaft, a driven gear, a driving gear, a first motor, a second clutch, a front main reduction driving gear, a front main reduction driven gear, a front differential, a second motor, a rear main reduction driving gear, a rear main reduction driven gear and a rear differential. The four-drive vehicle hybrid power system is simple in structure, one motor is arranged on a front drive axle, one motor is arranged on a rear drive axle, the structure is not dependent on the traditional automatic gearbox technology, and the structure is easy to design and manufacture; and by arranging the two clutches in a front power coupling box, thenine modes including three pure electric drive modes, three parallel drive modes, engine direct drive, series connection and a parking power generation mode can be achieved, and the system redundancyis increased.

Description

technical field [0001] The invention belongs to the technical field of hybrid vehicles, and in particular relates to a hybrid system and working method of a four-wheel drive vehicle. Background technique [0002] A hybrid vehicle refers to a vehicle equipped with more than two power sources. Currently, a hybrid vehicle generally refers to a vehicle whose power source is an internal combustion engine and an electric motor. [0003] At present, the structure of the hybrid system of the hybrid electric vehicle is mainly developed based on the traditional automatic transmission. Specifically, a motor can be integrated at the front end or rear end of a transmission such as an automatic transmission, a sequential transmission, a continuously variable transmission, or a dual-clutch transmission of an automobile, thereby forming a hybrid system of a hybrid electric vehicle. However, the design and manufacturing technology of automatic transmission is quite difficult, and many domes...
