The invention relates to the technical field of commercial vehicle electric drive axles, in particular to an electric drive axle transmission system for a new energy commercial vehicle type and a new energy commercial vehicle. The system comprises a first motor unit, a first transmission unit and a second transmission unit which are sequentially in transmission connection. In the first gear shifting unit, in the first state, the second transmission unit is in transmission connection with the third transmission unit. In the second state, the first transmission unit is in transmission connection with the third transmission unit through the first gear shifting unit. And in the third state, the third transmission unit is separated from the first transmission unit and the second transmission unit. The third transmission unit is in transmission connection with the second gear shifting unit. In the second gear shifting unit, in the fourth state, the second gear shifting unit is in transmission connection with the sun gear. And in the fifth state, the second gear shifting unit is in transmission connection with the planet carrier differential mechanism assembly. And in the sixth state, the second gear shifting unit is separated from the planet row unit. Therefore, the problem that various driving working conditions cannot be met due to few gears of the electric drive axle is solved.

    本发明涉及商用车电驱桥技术领域,具体而言,涉及一种新能源商用车型用电驱桥传动系统及新能源商用车。系统包括第一电机单元、第一传动单元、第二传动单元依次传动连接。第一换挡单元中,第一状态下,第二传动单元与第三传动单元传动连接。第二状态下,第一传动单元通过第一换挡单元与第三传动单元传动连接。第三状态下,第三传动单元脱离第一传动单元和第二传动单元。第三传动单元与第二换挡单元传动连接。第二换挡单元中,第四状态下,第二换挡单元与太阳轮传动连接。第五状态下,第二换挡单元与行星架差速器总成传动连接。第六状态下,第二换挡单元脱离行星排单元。这样就解决了电驱桥挡位少无法满足多种驾驶工况的问题。
