Differential drive

Abstract

A differential drive has a drivable differential carrier rotatably supported in a differential housing. Two axle shaft gears are rotatably held in cylindrical bores in the differential carrier. The axle shaft gears are coaxially arranged relative to each other. A plurality of differential gears are supported in bores in the differential carrier. The axle shaft gears rotate with the differential gears and are arranged axis-parallel. One group of the differential gears engage one of the axle shaft gears and another group of differential gears engage the other of the axle shaft gears. Each of the one group of the differential gears engage at least one of the other group of differential gears to achieve an uneven torque distribution between the axle shaft gears. Also, both the axle shaft gears have substantially equal rolling circle diameters and equal outer diameters and at least the gears of the one group of differential gears have two axially different regions with different rolling circle diameters. One of two regions engages one of the axle shaft gears and the other one engages at least one of the other group of differential gears.
