Abstract
A differential drive for use on a vehicle to control the transfer of torque between the front and rear axles of a vehicle. The differential drive includes a rotatably driven differential housing supported in a housing. The differential drive also includes a differential gear set arranged and supporting in the differential housing. The differential gear set has at least two side shafts gears and at least two differential gears. The differential drive also includes a torque distribution device having a viscous transmission. The viscous transmission has an inner hub and an outer casing. The inner hub is connected to a first side shaft. The outer casing is connected to one of the side gears. The viscous transmission also connects the output of the first side shaft to one of the side shaft gears.
