Abstract

A differential gear having a gear housing, an epicyclic gear housing which is arranged in the gear housing in a manner allowing rotation about a gear axis, a planetary carrier which is arranged in the epicyclic gear housing coaxial to the gear axle, a first output sun gear, a second output sun gear, a planetary arrangement accommodated in the planetary carrier for the purpose of coupling the two output sun gears in a manner allowing rotation in opposite directions, a brake device having a brake disk pack for the purpose of generating a coupling torque which couples the planetary carrier to the epicyclic gear housing, and an actuating mechanism for the purpose of generating an axial force which engages the brake device. The planetary arrangement comprises multiple revolving planets which as such are able to rotate about planetary axes which are oriented parallel to the gear axle.
