The efficient four-gear electric drive axle transmission system comprises a first input unit, a second input unit and a third input unit, the intermediate shaft is fixedly connected with a first gear shifter and a second gear shifter and is sleeved with a first gear shifting driven gear, a second gear shifting driven gear and a third gear shifting driving gear in a relatively rotating manner; the first transmission unit comprises a second parallel shaft, a third gear shifting driven gear and a fourth gear shifting driving gear, wherein the third gear shifting driven gear and the fourth gear shifting driving gear are fixedly connected to the second parallel shaft. The differential mechanism is provided with a first power output half shaft and a second power output half shaft, the periphery of a shell of the differential mechanism is sleeved with a fourth gear shifting driven gear, and the fourth gear shifting driving gear is used for transmitting power to the fourth gear shifting driven gear. A second shifter is selectively coupled to the third shift driving gear or the fourth shift driven gear for transmitting power from the intermediate shaft to the third shift driving gear or the fourth shift driven gear. The gear shifting ratio among the four gears is greatly reduced, the gear shifting impact can be reduced, and the working efficiency of the motor can also be improved.
提供了一种高效四挡电驱桥传动系统,包括:第一输入单元;中间轴,固定连接有第一换挡器和第二换挡器且可相对转动地套设有第一换挡被动齿轮、第二换挡被动齿轮和第三换挡主动齿轮;第一传动单元,包括第二平行轴以及固定连接于第二平行轴的第三换挡被动齿轮和第四换挡主动齿轮;以及差速器,设置有第一动力输出半轴和第二动力输出半轴且该差速器的壳体外周套设有第四换挡被动齿轮,第四换挡主动齿轮用于将动力传递至第四换挡被动齿轮,第二换挡器可选择地结合至第三换挡主动齿轮或第四换挡被动齿轮以用于将来自中间轴的动力传递至第三换挡主动齿轮或第四换挡被动齿轮。四挡位之间的换挡间比大大减小,能降低换挡冲击,也能提高电机的工作效率。
