The invention discloses an electric drive axle and an automobile. The electric drive axle is transversely arranged on a vehicle chassis and comprises a motor assembly, a speed reducer assembly and a differential mechanism assembly, the motor assembly and the differential mechanism assembly are arranged on the two sides of the speed reducer assembly respectively, and the speed reducer assembly comprises a three-stage speed reducing mechanism; in the electric working condition, motor power is decelerated through the three-stage speed reducing mechanism and then transmitted to the differential assembly, and the differential assembly distributes and outputs the power to the left wheel and the right wheel of the vehicle. The electric drive axle is small in occupied space and balanced in overall weight distribution, and the safety of an automobile is improved; the three-stage speed reducing mechanism prevents a high-speed motor shaft from directly transmitting power to a gear set of the differential mechanism assembly, and the stability and reliability of the electric drive axle are improved.

    本申请公开了一种电驱桥和汽车。电驱桥横向设置于车辆底盘,包括电机总成、减速器总成以及差速器总成,所述电机总成和差速器总成分别设置于所述减速器总成的两侧,所述减速器总成包括三级减速机构;电动工况时,电机动力通过所述三级减速机构减速后传递给所述差速器总成,所述差速器总成分配并输出动力至车辆的左右车轮。本申请中的电驱桥占用空间小,整体重量分配均衡,提高了汽车的安全性;三级减速机构避免了高速电机轴直接传递动力至差速器总成的齿轮组,提高了电驱桥的稳定性和可靠性。
