Abstract
A nutating gear positraction differential composed of two cam operated nutating gear sets, wherein the axles or shafts are connected to the cams of their respective gear sets; the cam operated gear sets transmit motion only from the cams to the gears and not in reverse. This forces the gear sets to lock up as soon as one cam loses its load.
