Abstract
An electrical drive unit for a motor vehicle, with the drive unit including a wheel hub drive that drives a vehicle wheel. The wheel hub drive has a sealing element which is affected by friction and by means of which the interior of the wheel hub drive is sealed off from the surroundings in an airtight manner. A ventilation device is provided by which a pressure difference between the prevailing air pressure in the interior of the wheel hub drive and the prevailing air pressure of the surrounding air can be compensated by displacing volumes of air.

Electrical drive unit for a motor vehicle, comprising a wheel hub drive adapted to drive a vehicle wheel,
- wherein the wheel hub drive has a sealing element that is exposed to friction and by which an interior of the wheel hub drive at least in a region of the sealing element is closed air-tight relative to its surroundings, and
- a ventilation device by which a pressure difference between air pressure predominating in the interior of the wheel hub drive and air pressure predominating in a surrounding area is equalizable by displacement of air volumes.
