ABSTRACT:
The invention relates to a driving axle for electric motor-driven vehicles provided with at least one electric motor mounted on the axle and drive shafts driven by the motor shaft thereof with a planetary gear step inserted therebetween, connected to the output shafts bearing the wheels resting on the drive axle with a braking device and another planetary gear inserted therebetween. The invention is characterised in that two controlled asynchronous motors (10, 11) are disposed on the axle, said motors working separately and being controlled by a common control in the working functions thereof. The motor shafts (13) of both asynchronous motors (10, 11) are connected respectively by the planetary gear step (15, 16, 17) to the drive shaft (19) driving the downstream output shaft (24).
