Abstract
A drive axle for an electric vehicle which comprises first and second electric machines (EM, EM), first and second drive wheels (R, R) and first and second two-speed transmissions (G, G) each having the same gear ratios. The first electric machine (EM) drives the first drive wheel (R) by way of the first two-speed transmission (G) and the second electric machine (EM) drives the second drive wheel (R) by way of the second two-speed transmission (G). The first and the second two-speed transmissions (G, G) each comprise a first planetary gearset (PS) and a second planetary gearset (PS) coupled to one another. The first planetary gearset (PS) and the second planetary gearset (PS) each comprise a web shaft (ST, ST), a ring-gear shaft (HR, HR) and a sun-gear shaft (SO, SO).
