An electric drive axle system is provided. The system comprises: a first input unit; a second input unit; an intermediate shaft, which is sleeved on a first output half shaft in a relatively rotating manner; an intermediate shaft gear, which is connected to the first end of the intermediate shaft and meshed with a first parallel shaft gears of the first input unit and the second input unit respectively; a first planet row, which comprises a first sun gear, a first planet gear, a first gear ring and a first planet carrier, wherein the first sun gear is connected to the second end of the intermediate shaft; and a differential mechanism, which comprises a differential mechanism shell, a first output end and a second output end, wherein the differential mechanism shell is connected with the first planet carrier, the first output end is connected with the first output half shaft, and the second output end is connected with the second output half shaft. The requirement for a large reduction ratio and gear shifting without power interruption can be met, the double motors are arranged externally, the size of a single motor can be reduced, and maintenance of the motors is facilitated.
提供了一种电驱动桥系统,包括:第一输入单元和第二输入单元;中间轴,可相对转动地套设于第一输出半轴;中间轴齿轮,连接于所述中间轴的第一端且分别与所述第一输入单元和第二输入单元的第一平行轴齿轮啮合;第一行星排,包括第一太阳轮、第一行星轮、第一齿圈和第一行星架,所述第一太阳轮连接于所述中间轴的第二端;以及差速器,包括差速器壳、第一输出端和第二输出端,所述差速器壳与所述第一行星架连接,第一输出端与所述第一输出半轴连接,第二输出端与第二输出半轴连接。可实现大减速比的需求以及无动力中断换挡,采用双电机外置的方式布置,可减小单个电机的尺寸,方便电机的维护与保养。
