摘要:
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.
