ABSTRACT:
A differential gear includes a power-transmission element, e.g. gear, which distributes rotation from a drive motor to two shafts by way of a gear connection. Two identically designed cam-track disks are opposite the shafts, are mounted coaxially to the power-transmission element, can be turned relative to it. The cam-track disks each have at least one inner and one outer cam track on the surfaces facing each other. The cam tracks have variable heights in axial directions, distributed along the peripheries and are connected by at least one rolling member which rolls on the cam tracks of both cam-track disks. This rolling member is connected to the power-transmission element, in such a way that the axis of rotation of the rolling member is positioned radially to the power-transmission element and, at the same time, the rolling member can be moved crosswise to the rotational axis.
