Differential gear for a multi-shaft wheeled motor vehicle, and a drive train comprising several such differential gears
摘要：
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.
摘要（中）：

一种差速齿轮，包括在冠轮（14）和一个驱动轴之间的第一可释放锁（42,44），在冠轮（14）和差速器壳体（24）之间的第二可释放锁（66,68） ）和在差速器壳体（24）和固定车辆部件（26）之间的第三可释放锁（74,76）。 第二和第三锁被设计成彼此交替地打开和锁定。 从而可以实现在车辆的左侧和右侧彼此相反方向转动的驱动轴，从而当第一锁（42,44）同时保持在锁定位置时实现车辆的中心旋转 。
