The invention provides a compact type single-motor drive axle which is composed of a single-motor power input unit, a power gear shifting unit and a power output unit, and the power gear shifting unit is composed of a first center shaft, a second center shaft, a third center shaft, a fourth center shaft, a fifth center shaft and a sixth center shaft. The driving joint tooth is fixedly connected to the first central shaft; the second central shaft is sleeved outside the first central shaft in a relatively rotating manner; the double-star planet row is fixedly connected to the second center shaft, and a gear ring of the double-star planet row is connected with the first center shaft; the joint gear sleeve is connected to the second central shaft; the short shaft is sleeved outside the second central shaft in a relatively rotating manner and is connected with a planet carrier of the double-star planet row; the power input gear is fixedly connected to the short shaft and is used for receiving power from the single-motor power input unit; and a brake engaging tooth connected to the housing. The requirements of different road conditions for power, vehicle speed and economical efficiency can be met, and the bearing capacity and reliability are improved.

    提供了一种紧凑型单电机驱动桥,由单电机动力输入单元、动力换挡单元以及动力输出单元组成:其中,所述动力换挡单元由以下部件组成:第一中心轴,用于将动力传递至动力输出单元;驱动接合齿,固定连接于第一中心轴;第二中心轴,可相对转动地套设于第一中心轴外;双星行星排,固定连接于第二中心轴,且该双星行星排的齿圈与第一中心轴连接;接合齿套,连接于第二中心轴;短轴,可相对转动地套接于第二中心轴外,且与双星行星排的行星架连接;动力输入齿轮,固定连接于短轴且用于接收来自单电机动力输入单元的动力;以及制动接合齿,连接于箱体。可满足不同路况对于动力、车速、经济性的要求,提升了承载能力和可靠性。
