The invention relates to a planet row hybrid power system and a vehicle. The system comprises an engine, a front power mechanism and a rear power mechanism, wherein the front power mechanism comprisesa front planet row, a first lock-up clutch and a first motor, the rear power mechanism comprises a system output shaft, the first lock-up clutch is arranged between any two elements of a front sun gear, a front planet carrier and a front gear ring of the front planet row. When the first lock-up clutch is combined, the two corresponding elements are locked together, the two elements rotate at thesame speed in the same direction, the rotating speed and the direction of the third element except the two elements are the same as those of the two elements, and the whole front planet row becomes adirect gear mechanism; when large torque output is needed, only the output torque of the engine needs to be increased to the same degree, and the output torque of the engine does not need to be increased to a larger degree, so that the possibility that the engine does not run in a high-efficiency area any more due to the fact that the output torque is too large is reduced, and then the running efficiency of the engine is improved.
本发明涉及一种行星排混合动力系统及车辆,系统包括发动机、前动力机构和后动力机构,前动力机构包括前行星排、第一锁止离合器和第一电机,后动力机构包括系统输出轴,前行星排的前太阳轮、前行星架和前齿圈中的某两个元件之间设置第一锁止离合器。当第一锁止离合器结合时,对应的两个元件锁止在一起,则这两个元件同速同向转动,而除了这两个元件之外的第三个元件的转速和方向与这两个元件相同,整个前行星排就变成了直接挡机构,当需要较大扭矩输出时,只需要同等程度增大发动机输出扭矩即可,无需更大程度增加发动机的输出扭矩,降低了发动机因输出扭矩过大从而不再运行在高效区的可能性,进而提升发动机的运行效率。
