Abstract

A drive device for an electrically driven axle of a motor vehicle, has, as appropriate, a driving electric machine, a transmission gearing and a differential which, via drive output shafts, outputs drive power to driven wheels of the motor vehicle. The transmission gearing is formed by two planetary gear sets which are coupled to one another and which can be switched into two transmission ratio stages by way of switching elements.
