The invention provides a transmission, an extended-range hybrid power system and a vehicle. The transmission comprises an input shaft and an output shaft, the output shaft is connected with a differential mechanism, the input shaft is connected with a driving motor, and the speed changer further comprises a planetary gear mechanism and a plurality of groups of shift gear pairs coupled between theoutput shaft and the input shaft. The shift gear pairs are connected with the output shaft through the planetary gear mechanism. By arranging the multiple shift gear pairs, so the multi-shift transmission can be achieved, and the energy conversion rate during high-speed driving is increased; and in addition, the planetary gear mechanism is further arranged, and the shift gear pairs are connected with the output shaft through the planetary gear mechanism, so the overall transmission efficiency of the mechanism can be improved, and the energy conversion rate is further increased.

    本发明提供一种变速器、增程式混合动力系统及车辆,变速器包括输入轴及输出轴,所述输出轴连接差速器,所述输入轴连接驱动电机,所述变速器还包括行星齿轮机构、及耦合连接在所述输出轴和所述输入轴之间的多组档位齿轮副,所述档位齿轮副通过所述行星齿轮机构连接所述输出轴。本发明通过设置多组档位齿轮副,可以实现多档变速器,提高高速行驶时能量转化率,此外还设置行星齿轮机构,档位齿轮副通过行星齿轮机构连接输出轴,可以提高机构的整体传动效率,进一步提高能量转化率。
