Abstract
A differential for delivering vectored torque to left and right axle shafts that rotate about an axis includes a cage which rotates about the axis as a consequence of torque applied to it. The cage contains gearing that transfers the torque to the axle shafts while accommodating for variances in angular velocity between the axle shafts. In addition, the differential has left and right torque diverters, each of which includes a ring gear on the cage, a sun gear on the axle shaft with which it is identified, planet gears between the ring and sun gears, and a carrier for providing axes about which the planet gears rotate. Each diverter also has a brake which resists rotation of the carrier for the diverter and thereby causes torque to transfer from the cage to the axle shaft while bypassing the gearing. The brakes control the torque delivered to the axle shafts, so the differential has the capacity to vector the torque applied to its cage.
