Abstract
A differential drive has a differential carrier rotatably supported in a differential housing. Two axle shaft gears are rotatably held in cylindrical bores in the differential carrier and are arranged coaxially relative to each other. Several differential gears, in an axis-parallel arrangement, are supported in an axle-free way in bores in the differential carrier. One group of differential gears engages one of the axle shaft gears and another group engages the other axle shaft gear. At least one group of the differential gears engages the other group of differential gears. The axle shaft gears or differential gears radially deviate from a complete symmetry so that at least periodically there occurs a friction contact between the axle shaft gears and their cylindrical bore in the differential carrier.
