ABSTRACT:
A differential drive having a drivable differential carrier rotatably supported in a drive housing, said differential carrier comprising a carrier portion and two cover parts. Two axle shaft gears are coaxially rotatably supported in the differential carrier. Further, two sets of differential gears are slidingly received on their tooth heads, in axis-parallel cylindrical bores in the carrier portion. The axis-parallel cylindrical bores are in the form of through-bores in the carrier portion. The differential gears comprise spacing journals with ends having friction bearing portions. Corresponding friction bearing sections are formed in the differential carrier, axially adjoining the carrier portion.
