More Information
Summary:An electric drive for driving a motor vehicle comprises a housing assembly; an electric motor having a motor shaft provided in the form of a hollow shaft which is rotatingly drivable around a rotational axis A and which is connected to a drive gear; a transmission unit having at least one transmission shaft which is rotatingly drivable by the drive gear and having at least one output shaft, the output shaft extending through the hollow shaft; wherein between the hollow shaft and the output shaft an annular channel is formed, having a first opening facing the transmission unit and a second opening facing away from the transmission unit; wherein the housing assembly comprises a lubricant-guiding geometry that is configured to guide lubricant into a mouth region of the first opening of the annular channel, so that the lubricant can flow through the annular channel to the second opening.
