The invention provides a coupling system of a hybrid electric vehicle. The coupling system comprises an engine, a generator, a driving motor, a power output mechanism and a transmission system. The transmission system is in transmission connection with the engine, the generator, the driving motor and the power output mechanism. Wherein the transmission system comprises a planetary gear mechanism, a first shaft gear transmission mechanism, a first clutch and a second clutch, and the coupling system can achieve switching of multiple working modes by controlling starting and stopping of an engine, a power generator and a driving motor and controlling disengagement and closing of the first clutch and the second clutch. Different working environments can be adapted; and the engine can always work in the optimal state, so that the fuel efficiency of the whole vehicle is improved.
本发明提供一种混合动力汽车的耦合系统,包括发动机、发电机、驱动电机、动力输出机构、以及传动系统;传动系统分别与发动机、发电机、驱动电机、动力输出机构传动连接;其中,传动系统包括行星齿轮机构、第一轴齿传动机构、第一离合器和第二离合器,且通过分别控制发动机、发电机及驱动电机的启动和停止,第一离合器及第二离合器的脱离和闭合,该耦合系统可以实现多种工作模式的切换,以适应不同的工作环境;使发动机可始终工作在最佳状态,以提高整体车辆的燃油效率。
