The invention discloses a dual-motor dual-planet-row electromechanical coupling transmission device. Compared with a Toyota THS system scheme device, only one brake is added, braking can be achieved through a jaw clutch and an electric actuating mechanism, a hydraulic system does not need to be additionally arranged, and driving mode switching is achieved. Meanwhile, through opening or closing ofthe brake B1, the structure can be switched to the engine direct drive mode when power circulation occurs in the ECVT mode, the mechanical efficiency of a mechanical system is improved, and the economical efficiency of the high-speed working condition is improved. And the second motor E2 is connected with the output end through a planet row speed reducing mechanism, so that a larger transmission ratio can be realized, and the system is better than a Toyota THS system.
本发明公开了一种双电机双行星排机电耦合传动装置,相比于丰田THS系统方案装置,本发明仅增加了一个制动器,可通过牙嵌式离合器制动,通过电动的执行机构实现,无需增加液压系统,实现驾驶模式切换。同时,通过制动器B1的打开或闭合,该构型可以在ECVT模式发生功率循环时,切换到发动机直驱模式,提高机械系统机械效率,改善高速工况的经济性。第二电机E2通过一行星排减速机构与输出端相连,可实现更大的传动比,比丰田THS系统更优。
