The invention relates to a two-gear integrated electric drive axle which comprises a drive motor. The three-stage parallel shaft reducing mechanism comprises a first-stage gear mechanism, a second-stage gear mechanism and a third-stage gear mechanism; the planet row gear shifting mechanism comprises a planet speed reducing mechanism, a first transmission gear, a gear shifting executing mechanism, a power combination gear, a second transmission gear and a third transmission gear. The input end of the planetary reduction mechanism, the first transmission gear and the output end of the second-stage gear mechanism are coaxially arranged, the third transmission gear and the input end of the third-stage gear mechanism are coaxially arranged, and the gear shifting execution mechanism is used for connecting a power combination gear with the first transmission gear and the input end of the planetary reduction mechanism; a differential; the transmission speed ratio is large, the output torque is high, gear shifting is smooth, the noise suppression performance is excellent, the speed ratio coverage range is wide, the application range is wide, the structure is compact, and the weight is light.
