The two-gear electric driving system comprises a driving motor, a speed reduction transmission mechanism, a speed changer and a differential mechanism, the driving motor is provided with an output shaft, the speed reduction transmission mechanism is connected with the output shaft, and the output rotating speed of the output shaft is reduced after being transmitted by the speed reduction transmission mechanism; the transmission comprises a planetary mechanism, a brake and a clutch, the planetary mechanism comprises a sun gear, a planet gear structure and a gear ring, the planet gear structure is connected with the output end of the speed reduction transmission mechanism, the brake is arranged between the sun gear and the transmission shell, and the clutch is arranged between the sun gear and the speed reduction transmission mechanism. The differential mechanism is connected with the planetary mechanism through the second transmission mechanism, the rotating speed output by the driving motor is transmitted into the transmission after passing through the speed reduction transmission mechanism, the torque needing to be borne by a clutch in the transmission is reduced, and therefore the driving system can be matched with the driving motor with the higher rotating speed.

    本发明公开一种两挡电驱动系统、电动汽车的动力系统以及电动汽车,包括:驱动电机、减速传动机构、变速器和差速器,驱动电机设置有输出轴,减速传动机构与输出轴连接,输出轴输出转速经过减速传动机构传动后转速降低,变速器包括行星机构、制动器和离合器,行星机构包括太阳轮、行星轮结构和齿圈,行星轮结构与减速传动机构的输出端连接,制动器设置在所述太阳轮与所述变速器壳体之间,离合器设置在太阳轮与减速传动机构之间,差速器通过第二传动机构与行星机构连接,驱动电机输出的转速先经过减速传动机构再传递到变速器中,变速器中的离合器所需承载的扭矩降低,使驱动系统可以适配更高转速的驱动电机。
