The invention relates to a hybrid power system, in particular to a hybrid power system with a planetary gear train and a vehicle. According to the hybrid power system with the planetary gear train, an output shaft of a driving motor is in transmission connection with a main output shaft through a reduction gear mechanism, the reduction gear mechanism comprises at least two reduction output gears, and the main output shaft is sleeved with the reduction output gears; the main output shaft is provided with a gear shifting gear selectively connected with the multiple speed reduction output gears. When the driving motor is connected with the main output shaft through the reduction gear mechanism, the rotating speed of the driving motor is greater than that of the main output shaft, so that the driving motor with higher rotating speed and higher power can be selected, and the torque required to be provided by the engine is reduced; the problems that in the prior art, due to the fact that an output shaft of a driving motor is arranged on a main output shaft in a sleeving mode, the speed ratio of one gear in two-gear electric drive is 1, power selection of the driving motor is limited, and the specification of an engine cannot be reduced are solved.
本发明涉及混合动力系统,尤其涉及一种具有行星轮系的混合动力系统及车辆。具有行星轮系的混合动力系统,驱动电机的输出轴通过减速齿轮机构与主输出轴传动连接,减速齿轮机构包括至少两个减速输出齿轮,各个减速输出齿轮均套设在主输出轴的外部,主输出轴上设置有与多个减速输出齿轮选择性连接的换挡齿轮。由于驱动电机与主输出轴通过减速齿轮机构进行连接时,驱动电机的转速大于主输出轴的转速,那么就能选择转速更高,功率更大的驱动电机,进而使得发动机所需要提供的扭矩得以变小,解决了现有技术中驱动电机的输出轴由于套设在总输出轴上使得两档电驱动中的其中一档速比为1进而导致的驱动电机功率选取受限,发动机规格无法降低的问题。
