Abstract
A coolant supply system for an electric vehicle axle drive having an electric machine, in the electric machine housing of which a stator interacts with a rotor. The electric machine outputs to at least one vehicle wheel of the vehicle axle via a transmission arrangement. A coolant separator is arranged in the electric machine housing, which divides the interior of the electric machine housing into a radially outer stator chamber, in which the stator with its stator windings is arranged, and into a radially inner rotor chamber, which is separated therefrom in a largely fluid-tight manner and in which the rotor is arranged.
