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.

Drive device for a motor vehicle axle which, in particular, is electrically-driven

A planetary gear () for variable transmission, particularly a planetary gear for variable transmission towards a tail rotor of a helicopter. At least one gear set (s, s, s, s) of a sun gear (w, w) comprises a ring gear (w, w), planetary wheels () and a planet carrier (w, w, w). At least one clutch (k, K, K) and at least one freewheel (Fl, FL, FL) are provided for at least two different speeds of the planet carrier (w, w, w) as output.
