ABSTRACT:
A differential gear system for use in the driveline of a motor vehicle, having a differential carrier (1) rotating in bearing of a differential housing (1) and driven via a driving gear tooth configuration; two axle shaft gears (10, 11) rotating in bearings of the differential carrier, which are coaxial relative to each other; and compensating gears (12, 13) eccentrically supported in, and rotating with, the differential carrier, where each of the compensating gears is in one part meshed with the one axle shaft gear (10) and in another part, with the other axle shaft gear (11), while engaging each other at least indirectly, and where the axle shaft gears (10, 11) have a tooth design which, when under torque, generates an axial thrust, and where friction-reducing means are provided at all face areas of at least the axle shaft gears (10, 11) that are subjected to loads during coasting of the motor vehicle, opposite the mating surfaces of the differential carrier (1) or the respective other axle shaft gear.
