The invention relates to the field of electric drive axles, in particular to a two-gear speed change type electric drive axle which comprises a shell. A driving shaft is arranged at the working end of the motor; the differential mechanism comprises a first output shaft and a second output shaft; a first speed change mechanism; a second speed change mechanism; and a clutch. The electric drive axle has the beneficial effects that the first speed change mechanism and the second speed change mechanism are arranged and matched with the speed changer and the clutch, so that the gradeability and the high-speed running ability of a vehicle can be effectively improved, the electric drive axle integrally adopts a double-gear speed change mode, the working efficiency of the electric drive axle is improved, and the service life of the electric drive axle is prolonged. A low-speed gear and a high-speed gear are convenient to switch, the energy conversion efficiency of the battery is improved, an efficient power transmission mode is adopted, and the service life of the electric drive axle is prolonged.

    本发明涉及电驱动桥领域,尤其是涉及一种两档变速式电驱动桥,包括:壳体;电机,电机的工作端设置有驱动轴;差速器,包括第一输出轴与第二输出轴;第一变速机构;第二变速机构;离合器。本发明的有益效果是:通过设置有第一变速机构和第二变速机构,再配合上变速器、离合器,使得车辆的爬坡能力和高速行驶能力能够得到有效得提高,电驱动桥整体采用双挡变速的模式,提高了电驱动桥的工作效率,低速挡和高速挡切换便捷,增加了电池的能量转换效率,采用高效的动力传递模式,也提高了电驱动桥的使用寿命。
