A differential gearing has a power transmission element e.g., a crown wheel (14, Figure 1) which distributes the rotational movement from a propulsion motor through a gear connection to two axles. The invention is char-acterized by two cam plates (16, 18, Figure 1) that are opposite each other axially, are configured in an identical manner, and arranged coaxially to the power transmission element. The cam plates rotatable relative to the power transmission element and have at least one inner (30) and one outer (32) cam surface that face each other. The cam surfaces are of variable height viewed in the axial direction around the perimeter. At least one roller (20, 22, Figure 1) for each cam surface (30, 32) of the two cam plates (16, 18) is connected to the power transmission element, e.g. the crown wheel (14) in such a manner that the rotational axis of the rollers runs radially to the power trans-mission element and the rollers can simultaneously be displaced transversely to the axis of rotation (see Figure 1). |
