Abstract

The invention relates to a multi-mode dynamic coupling system of a single-motor electric automobile, and belongs to the technical field of new energy automobiles. The system comprises an engine, a first planetary gear mechanism, a second planetary gear mechanism, a brake, a clutch, a synchronizer, an inverter, a power battery, a motor, a motor power output gear shaft, a transmission, a power output gear shaft and a main reducer and differential assembly. According to the system, by controlling engagement and disengagement of the clutch, the brake and the synchronizer, the coupling mode of themotor and the engine is changed, speed coupling drive of the motor and the engine, torque coupling drive of the motor and the engine and separate drive of the motor and separate drive of the engine are realized, the accelerating ability of the system is improved, the problems of low load and low efficiency of the engine are solved, and the path conversion loss of the system is reduced.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles and relates to a multi-mode power coupling system of a single-motor electric vehicle. Background technique [0002] With its advantages of low consumption and low pollution, new energy vehicles have become an important direction of automobile development. Among them, pure electric vehicles cannot be widely used due to their short mileage on a single charge, long charging time, and high vehicle manufacturing costs. Although hybrid electric vehicles are still mainly powered by fuel, compared with traditional fuel vehicles, the energy utilization rate has been significantly improved, and pollution emissions have been significantly reduced. Mainstream automakers have carried out research and development in hybrid electric vehicles. manufacture. [0003] At present, in the hybrid electric system, the hybrid electric system with dual motors and engines as the power source has problems such...
