Claim Text:
1. A drive device for a motor vehicle, comprising: at least one electric machine having at least one rotor element which is configured to delimit an installation area in a radial direction; at least one transmission device disposed, at least partly, in the installation area and configured to be driven by the electric machine via the rotor element; and a fluid supply device having at least one fluid channel for supply of fluid to at least one member selected from the group consisting of a cooling point and a lubrication point of the drive device for cooling or lubricating the at least one member, said fluid channel having a first part area running in a stationary first component, and a second part area which adjoins the first part area in a flow direction of the fluid through the fluid channel and runs in a second component of the drive device, said second component being supported for rotation about an axis of rotation in relation to the first component, wherein the first component is a transmission housing of the transmission device and is disposed in the installation area and cooled by the fluid, and wherein the fluid-cooled transmission housing defines with the rotor element in the radial direction at least one elongated air gap, which extends uninterruptedly in an axial direction between a radially inner surface of the rotor element and a radially outer surface of the fluid-cooled transmission housing and via which the rotor element is cooled by the fluid-cooled transmission housing.
