Abstract
A drive arrangement for an electric vehicle has an axle drive device of a portal design with two electric machines for driving the wheels of an axle of the electric vehicle, and at least one electric energy store that can be discharged when an electric machine is operated as a motor and/or can be charged when an electric machine is operated as a generator. The drive arranged is characterized in that the two electric machines () of the axle drive device () are combined with a respectively assigned transmission () in an electric axle to drive the individually suspended wheels () of the axle by means of, in each case, one articulated shaft flange () via a respective articulated shaft. Frequency converters assigned respectively to the two electric machines are combined in a converter unit.
