Zusammenfassung:	The invention relates to the technical field of vehicle power assemblies, in particular to an electric drive axle, a power assembly and an electric vehicle. The electric drive axle comprises a motor, a first planet row and a second planet row, an output shaft of the motor is connected with a sun gear of the first planet row, a gear ring of the first planet row is connected with an axle housing, a planet carrier of the first planet row is connected with a sun gear of the second planet row, a gear ring of the second planet row is connected with the axle housing, and a planet carrier of the second planet row is connected with a driving shaft; the motor, the first planet row and the second planet row are coaxially arranged on the driving shaft in a sleeving mode. According to the electric drive axle, through the arrangement mode that the motor, the first planet row and the second planet row are coaxially arranged on the drive shaft in the sleeving mode, it can be guaranteed that the cross section of the axle shel
