Abstract

A differential, including: a gear housing; an epicyclic housing which is mounted in the gear housing in a manner allowing rotation about a gear axis; a planet carrier arranged in the epicyclic housing in a manner allowing rotation; a first output sun gear; a second output sun gear; a planetary arrangement, accommodated in the planet carrier, coupling the output sun gears in a manner allowing opposite rotation; a brake device generating a bridging torque which places a load on relative rotation of the first and second output sun gears, according to a magnitude of an axial force applied to the brake device; and an actuating mechanism for the purpose of generating said axial force applied to the brake device. The actuating mechanism is designed in such a manner that the first bridging torque generated by the brake device increases as a rotary drive torque applied to the epicyclic housing increases.
