According to the multi-gear electric drive axle structure of the new energy truck, power output is achieved through cooperation of double motors and different speed ratios, and the motors fully work in a high-efficiency area. The system comprises two motors, specifically an EM-B motor and an EM-A motor; a group of reduction gear assemblies; a group of two-gear gear assemblies; the gear shifting planet row assembly comprises a main reduction gear, a sun gear shaft, a sun gear, a planet gear, a planet carrier and a high-low gear shifting assembly, the sun gear shaft is a hollow shaft, the input end of the sun gear shaft is sleeved with the main reduction gear, and the output end of the sun gear shaft is fixedly sleeved with the sun gear; a differential mechanism; and the two half shafts are respectively a left half shaft and a right half shaft.

    本发明提供了一种新能源卡车多挡电驱桥结构,其由双电机配合不同速比实现动力输出,电机充分工作在高效区。其包括:两电机,具体为EM‑B电机和EM‑A电机;一组减速齿轮组件;一组两挡齿轮组件;一组换挡行星排组件,其包括主减齿、太阳轮轴、太阳轮、行星轮、行星架,以及高低挡换挡组件,所述太阳轮轴为空心轴,所述太阳轮轴的输入端套装有所述主减齿,所述太阳轮轴的输出端固套有太阳轮;一差速器;以及两半轴,分别为左半轴、右半轴。
