Abstract:
A differential gear, comprising a first releasable lock (42, 44) between a crown wheel (14) and the one drive shaft, a second, releasable lock (66, 68) between the crown wheel (14) and a differential housing (24), and a third releasable lock (74, 76) between the differential housing (24) and fixed vehicle part (26). The second and third locks are designed to be opened and locked alternately with one another. It is thereby possible to achieve drive shafts rotating in opposite directions to one another on the left and right side of the vehicle and thereby to achieve a center swiveling of the vehicle when the first lock (42, 44) is simultaneously kept in the locked position.
