The invention discloses an integrated single-motor multi-gear electric drive axle system and a working method. A driving shaft of a driving motor is in transmission connection with an input shaft, an input gear is mounted on the input shaft, and an input driven gear is meshed with the input gear; the intermediate shaft gear is meshed with the low-gear gear and is hollowly sleeved on the output shaft; the output shaft is connected with a shaft head of the input shaft, one end of the hollow shaft is connected with the planet row, and a large gear at the other end of the hollow shaft is meshed with an output shaft gear. The planet row is connected with a differential mechanism, the differential mechanism is connected with a left half shaft and a right half shaft, the left half shaft is connected with a left wheel, and the right half shaft penetrates through a hollow shaft to be connected with a right wheel; when middle-gear power transmission is carried out, the hollow shaft is sleeved with a middle-gear gear in an idling mode, the middle-gear gear is meshed with the low-gear gear, and a second sliding sleeve is installed on the side face of the middle-gear gear and connected with the hollow shaft. The first sliding sleeve and the second sliding sleeve move and are combined with the corresponding gears to conduct power transmission of a low gear, a middle gear and a high gear.

    本发明公开了一种集成式单电机多挡位电驱动桥系统和工作方法,驱动电机的驱动轴与输入轴进行传动连接,输入轴上安装有输入齿轮,输入从动齿轮与输入齿轮啮合;中间轴齿轮与低挡齿轮啮合、并空套在输出轴上;输出轴与输入轴的轴头相连接,空心轴的一端与行星排相连,空心轴的另一端的大齿轮与输出轴齿轮啮合;行星排与差速器相连接,差速器分别连接左半轴和右半轴,左半轴与左车轮相连,右半轴穿过空心轴与右车轮相连;当进行中间挡的动力传递时,空心轴上空套有中间挡齿轮,中间挡齿轮与低挡齿轮啮合,中间挡齿轮的侧面安装有第二滑套、并与空心轴连接;第一滑套和第二滑套进行移动,与对应的齿轮相结合,进行低挡、中间挡和高挡的动力传递。
