A coolant supply system for a drive device of an electrically operated vehicle axle with an electric machine which has a cylindrical stator housing, in which there is a winding head space axially on both sides of a rotor/stator arrangement, at the bottom of which coolant collects. The two winding head spaces are fluidly connected to one another via a coolant sump, and the stator housing height and the coolant sump height in the electric machine vertical direction add up to a total height. In order to reduce the total height, the coolant sump is offset by a transverse offset from a rotor axis vertical plane. In this way, the stator housing height and the coolant sump height can at least partially overlap in the vertical direction of the electric machine by an overlap amount.
