Zusammenfassung:	The invention relates to an externally controlled, lockable differential gear 8, whose friction arrangement 21 can be loaded via a selectively operable rotary drive 32, via a compression ring. To this end, a positioning ring 29, which can be driven by an electric motor 33 via a pinion 35, is provided which causes an axial displacement of the compression ring 28. The compression ring 28 is itself arranged such that it cannot rotate with respect to the housing 11. Control cams or profiles are provided on the mutually facing end surfaces 45, 46 of the compression ring 28 and of the positioning ring 29, which are effectively connected between the compression ring and the positioning ring in a supporting manner, moving the compression ring 28 when the positioning ring 29 rotates, and have a non-linear rate of change of the axial components acting on the compression ring 28 over the rotation angle of the positioning ring 29.
