Abstract
Axle-drive unit for a motor vehicle which contains a first and a second differential () in a driven housing (), the two differentials () being spur-gear-type planetary gears with parallel axes, the sun wheels () of which are in each case connected in terms of drive to the half axles () of the first driven axle, and planet wheels () of the two differentials () meshing with their common ring gear (). The housing () has a machined inner surface () which surrounds the ring gear () with little clearance, the ring gear is so thin in the radial direction that it is deformed in a lobe-like manner by the radial component of the tooth forces exerted by the planet wheels (). The outer circumferential surface () of the ring gear is placed against the inner surface () of the housing () in a manner producing friction at least locally.
