Abstract

An active differential assembly provides speed control of an associated output shaft. A differential case is rotatably mounted within a housing to drive a pair of output shafts extending from the differential case in opposite directions for distributing driving force from the engine to wheels. A pair of planetary gear sets are one each disposed about a corresponding output shaft and includes a planetary ring gear, a sun gear fixed to the output shaft, and a planetary carrier rotatably supporting a plurality of planet gears operatively coupling the planetary ring gear with the sun gear. A brake mechanism is disposed between the planetary ring gear and the housing for selectively braking the planetary ring gear to thereby cause an associated increase in speed of the axle shaft.
