The parallel shaft type single-motor three-gear electric drive axle comprises a first shaft driven by a motor and provided with a first joint sleeve, a first gear, a second gear and a third gear, and the first joint sleeve is used for transmitting or disconnecting power of the first shaft to the first gear; the second shaft is provided with a fourth gear, a fifth gear, a second joint sleeve and a sixth gear, and the second joint sleeve is used for transmitting or disconnecting power of the fifth gear or the sixth gear to the second shaft; the differential mechanism is connected with a first output half shaft and a second output half shaft; the seventh gear is arranged on the periphery of the shell of the differential mechanism in a sleeving manner; wherein the first gear and the seventh gear are meshed with the fourth gear, the second gear is meshed with the fifth gear, and the third gear is meshed with the sixth gear. The drive axle integrates the single motor and the three-gear parallel shaft arrangement type speed change mechanism, the structure is compact and simple, large reduction ratio transmission can be achieved, the transmission efficiency is effectively improved, the requirement for large torque of the motor is lowered, and the size of the motor is reduced.

    提供了一种平行轴式单电机三挡电驱动桥,包括:第一轴,由电机驱动且设置有第一接合套、第一齿轮、第二齿轮和第三齿轮,第一接合套用于传递或断开第一轴的动力至第一齿轮;第二轴,设置有第四齿轮、第五齿轮、第二接合套和第六齿轮,第二接合套用于传递或断开第五齿轮或第六齿轮的动力至第二轴;差速器,连接有第一输出半轴和第二输出半轴;以及第七齿轮,套设于差速器的壳体外周;其中,第一齿轮和第七齿轮与第四齿轮啮合,第二齿轮与第五齿轮啮合,第三齿轮与第六齿轮啮合。该驱动桥集成单电机和三挡平行轴布置式变速机构,结构紧凑简单,并且可以实现大减速比传动,有效提高传动效率,以降低对电机大扭矩的需求,减少电机尺寸。
