为了解决上述技术问题，本发明采用的技术方案为：一种共太阳轮式双行星排混合动力装置，包括发动机、主电机和副电机，发动机、主电机和副电机单独或合力地驱动输出轴，所述发动机、主电机和/或副电机与输出轴之间连接至少两组行星排，两组行星排相互同轴地安装。
进一步地，所述行星排包括太阳轮、行星轮、齿圈和转臂，太阳轮外啮合传动行星轮，行星轮内啮合传动齿圈，转臂安装于行星轮；所述两组行星排的太阳轮相互同轴地安装；所述发动机驱动连接其中一转臂，主电机和副电机分别驱动连接齿圈；所述另一转臂传动连接输出轴。
进一步地，所述齿圈具有内齿圈和外齿轮；所述行星轮内啮合传动齿圈的内齿圈；所述主电机和副电机分别驱动连接齿圈的外齿轮。
本发明采用的另一技术方案为：一种共太阳轮式双行星排混合动力驱动方法，首先，启动发动机和主电机的同时制动共同太阳轮；然后，发动机驱动副转臂转动，副转臂将动力传递给副行星轮，副行星轮传动副齿圈，副齿圈反向传递给副电机产生电能并存储，同时，主电机驱动主齿圈转动，主齿圈将动力传递给主行星轮，主行星轮传动主转臂，主转臂将动力传递给输出轴，实现ISG驱动模式。
进一步地，首先，启动发动机和主电机的同时关闭副电机；接着，发动机驱动副转臂转动，副转臂将动力传递给副行星轮，副行星轮传动共同太阳轮，共同太阳轮传动主行星轮，同时，主电机驱动主齿圈转动，主齿圈将动力传递给主行星轮；最后主行星轮将动力传递给输出轴，实现发动机与主电机联合驱动模式。
进一步地，首先，启动发动机、副电机和主电机；接着，发动机驱动副转臂转动，副转臂将动力传递给副行星轮，副行星轮传动共同太阳轮，同时，副电机驱动副行星轮，副行星轮将动力传递给共同太阳轮，共同太阳轮将动力传递给主行星轮，同时，主电机驱动主齿圈转动，主齿圈将动力传递给主行星轮；最后，主行星轮将叠加动力传递给主转臂，主转臂将动力传递给输出轴，实现发动机、副电机和主电机联合驱动模式。
实施上述技术方案，由于增设了同轴安装的两组行星排，当启动或关闭相应的发动机、主电机和/或副电机时，实现了单独发动机驱动、ISG驱动、单独电机驱动以及发动机与电机联合驱动等模式，丰富和灵活的驱动模式使传动***更简洁，降低了***转动惯量、振动噪音和损耗，增强了输出动力，适应于车辆混合传动***。
