The invention provides a series-parallel double-planetary-gear power coupling device. The series-parallel double-planetary-gear power coupling device comprises a differential gear train, an engine, a first motor, a second motor and an output mechanism. The differential gear train comprises a first planet gear, a first planet carrier, a first gear ring and a first sun gear; an output shaft of the engine is connected with the first planet carrier; an output shaft of the first motor is connected with a first sun gear; the second motor drives the first gear ring to rotate; the first gear ring drives the wheels to rotate through the output mechanism. In the invention, an engine drives a first planet carrier to rotate, a first motor drives a first sun gear to rotate, and a second motor drives a first gear ring to rotate; the first gear ring is driven by specifically controlling actions of the engine, the first motor and the second motor, the first gear ring drives the wheels to rotate through the output mechanism, a plurality of locking devices and clutches do not need to be controlled, and the complexity of a control strategy is effectively reduced.

    本发明提供了一种混联式双行星齿轮动力耦合装置,包括:差动轮系、发动机、第一电机、第二电机和输出机构;差动轮系包括第一行星轮、第一行星架、第一齿圈和第一太阳轮;发动机的输出轴连接第一行星架;第一电机的输出轴连接第一太阳轮;第二电机驱动第一齿圈转动;第一齿圈通过输出机构驱动车轮转动。本发明中,发动机驱动第一行星架转动,第一电机驱动第一太阳轮转动,第二电机驱动第一齿圈转动;通过具体控制发动机、第一电机和第二电机的动作来完成对第一齿圈的驱动,第一齿圈通过输出机构来驱动车轮转动,不需要控制多个锁止器和离合器,有效的降低了控制策略的复杂程度。
