Abstract: An active torque biasing differential includes a housing and an outer annulus disposed within the housing. An inner annulus is contained within the outer annulus. The inner annulus includes a plurality of slots. A plurality of vanes are disposed in the slots in the inner annulus. The vanes slidably contact the outer annulus. The vanes include a plurality of orifices formed therein. An electromagnetic coil is placed to apply a magnetic field to a chamber bounded by the outer annulus and inner annulus.

Abstract: Differential assembly and a method of operating the same. The assembly includes a differential case and a pinion housing including a first pinion gear and a second pinion gear positioned substantially therein. A first side gear and a second side gear are operably coupled to the first pinion gear and the second pinion gear. A sliding collar selectively engages at least one of the differential case, the pinion housing, and the first and second side gears. The sliding collar provides at least three engagement modes. The method includes providing a differential case and a pinion housing including a first pinion gear and a second pinion gear positioned substantially therein. A first side gear and a second side gear are provided. At least one of the differential case, the pinion housing, and the first and second side gears are selectively engaged in one of at least three engagement modes.
