Beschreibung
Zusammenfassung:	A drive axle for an electric vehicle which comprises first and second electric machines (EM1, EM2), first and second drive wheels (R1, R2) and first and second two-speed transmissions (G1, G2) each having the same gear ratios. The first electric machine (EM1) drives the first drive wheel (R1) by way of the first two-speed transmission (G1) and the second electric machine (EM2) drives the second drive wheel (R2) by way of the second two-speed transmission (G2). The first and the second two-speed transmissions (G1, G2) each comprise a first planetary gearset (PS1) and a second planetary gearset (PS2) coupled to one another. The first planetary gearset (PS1) and the second planetary gearset (PS2) each comprise a web shaft (ST1, ST2), a ring-gear shaft (HR1, HR2) and a sun-gear shaft (SO1, SO2).
