Zusammenfassung:	A drive axle of an electric vehicle has first and a second drive wheels (R1, R2) with wheel axles (a1, a2), a first electric machine (EM1) and a second electric machine (EM2) with a common rotation axis (m), a transmission (G3) with a transmission input shaft (EW) and a transmission output shaft (AW), and an axle differential (DI) with a differential input (DIK) and two differential output shafts (3a, 3b). The first electric machine (EM1) is connected to the transmission input shaft (EW) and the transmission output shaft (AW) is connected to the differential input (DIK). The second electric machine (EM2) can be connected as an additional drive when necessary.
