1270.001 POSITIVE CLUTCH DIFFERENTIAL ABSTRACT OF DISCLOSURE A differential assembly of the automotive vehicle type, for rotating axially aligned drive axles, having a rotatable driving casing which distributes the power to the inner end portions of the axles. A center ring member, having opposite wedge-like, face tooth formations, is secured within the casing for meshing with and driving corresponding tooth formations on a pair of pressure rings between which the center ring member is positioned. Each pressure ring is connected to one of the axles through a clutch. The pressure rings are movable towards and away from the center ring for respectively disengaging and engaging their clutches. A splined stop ring meshes with corresponding internal splines formed on each of the pressure rings for limiting each pressure ring's rotational movement relative to the center ring for holding the meshed center ring teeth and the teeth of either pressure ring apart when that pressure ring's rotational speed exceeds the rotational speed of the center ring and casing. During such speed conditions, the respective pressure ring can move towards the center ring so as to disengage its clutch and permit its axle to free wheel while the opposite axle is still driven by the rotating casing.
