Abstract

The invention provides an electric power assisting device and a hybrid power system for a car. The electric power assisting device comprises a motor and a decelerator. The motor is provided with a motor shaft, the decelerator is provided with the input end and the output end, the input end is connected with the motor shaft in a coaxial mode, the output end of the decelerator is provided with a driving reducing gear, the driving reducing gear is used for being engaged with a driven reducing gear of a gearbox, and the diameter of the driving reducing gear is shorter than that of the driven reducing gear. The hybrid power system comprises the electric power assisting system, an engine and the gearbox. The gearbox comprises a first axle and a second axle, the first axle is connected with the engine, and the second axle is engaged with the driving reducing gear of the output end of the decelerator through the driven reducing gear. The electric power assisting device occupies small space, is low in torque fluctuation and high in transmission efficiency, and can be integrated with the gearbox easily.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to an electric power booster and a hybrid power system. Background technique [0002] In the field of new energy vehicles, a 48V micro-hybrid system is gradually developed, which can better achieve energy saving, emission reduction and noise reduction functions, so it is favored by the majority of automobile manufacturers. [0003] The 48V micro-hybrid system is equipped with a 48V power recovery system. Compared with the traditional internal combustion engine drive, it adds three core components: a 48V power recovery motor, a 48V / 12V DC power converter, and a 48V lithium battery. , acceleration assist, electric crawling and other functions, and can also provide power for active suspension systems, electric resistance steering systems, brake vacuum assist systems, seat heating and other systems, thus solving the problem of insufficient output power of the power supp...
