Abstract

The invention discloses a single-motor multi-mode hybrid power system and an automobile, comprising an engine, a motor, a first transmission system, a second transmission system and a shift actuator. One end of the motor power input shaft is connected with the motor rotor, and the other end is connected with the motor rotor. The large sun gear connecting shaft is connected, the large sun gear connecting shaft is connected with the large sun gear, the engine power input shaft is connected with the active end of the first clutch and the passive end of the second clutch as a whole, coaxially rotates, and the small sun gear is connected One end of the shaft is connected to the passive end of the first clutch, the other end of the small sun gear is connected to the small sun gear, and the second transmission system combines the power of the engine and the motor to achieve different drives mode and variable speed output for various gears. The invention has the advantages of simple mechanism, easy repair, quick response to speed changes, and improved transmission efficiency.

Description

technical field [0001] The invention belongs to the field of automobile transmission systems, and in particular relates to a single-motor multi-mode hybrid power system and an automobile. Background technique [0002] With the increase of car ownership year by year, new energy vehicles, as a relatively environmentally friendly travel tool, are more and more popular among consumers. With the increasingly strict environmental protection measures around the world, hybrid vehicles have become a focus of automotive research and development due to their energy-saving and low-emission characteristics. Hybrid vehicles, like gasoline vehicles, go to the gas station to refuel, without changing the car's usage habits. The fuel economy is high and the driving performance is superior. The engine of the hybrid vehicle needs to use fuel, and when starting and accelerating, due to the assistance of the electric motor, the fuel consumption can be reduced, and the internal combustion engine ...
