  • Patent number: 10837536
    Abstract: A driveline power transmitting device that includes a limited slip differential having a differential case, a cross-pin, a pair of pressure rings, a pair of clutch packs, a pair of preload springs, and a pair of preload control mechanisms. The pressure rings are non-rotatably coupled to the differential case and are disposed on opposite sides of the cross-pin. The preload springs bias the pressure rings toward the clutch packs and thereby preload the clutch packs. The pressure rings are urged axially away from the cross-pin to further compress the clutch packs in response to rotation of the cross-pin relative to the differential case. The preload control mechanisms are employed to decrease the preload force on the clutch packs in certain situations.
