The invention provides a single-motor coaxial two-gear electric drive axle structure which comprises a drive motor. A deceleration planet row; a second hollow shaft; a clutch; a brake; a double-star planet row; and a compound planet row differential mechanism. After the speed reduction planet row decelerates, a high-low speed switching clutch is arranged on the double-star planet row, the rotating speed difference of planet row components during gear shifting is reduced, the service life of the clutch and the service life of a brake are prolonged, due to the design of the double-star planet row, the ratio of the high-gear transmission ratio to the low-gear transmission ratio is reduced, the impact of gear shifting is reduced, and the comfort of a vehicle is improved.

    提供了一种单电机同轴式两档电驱动桥结构,包括:驱动电机;减速行星排;第二空心轴;离合器;制动器;双星行星排;以及复合行星排差速器。减速行星排减速后,在双星行星排安排了高低速切换的离合器,减小了换挡时行星排构件的转速差,提高了离合器和制动器的寿命,双星行星排的设计使得高低档传动比之间的间比减小,降低换挡的冲击,提高了车辆的舒适性。
