A differential assembly includes a case (12), an input (30) for effecting rotation of the case, pinion means (36, 38) associated with the case, a pair of side gears (32, 34) meshing with the pinion means, a first output shaft (26) connected to one of the side gears and a second output shaft (28) con
A differential assembly includes a case (12), an input (30) for effecting rotation of the case, pinion means (36, 38) associated with the case, a pair of side gears (32, 34) meshing with the pinion means, a first output shaft (26) connected to one of the side gears and a second output shaft (28) connected to the other of the side gears. The differential assembly further includes a first gear train (54) associated with the first output shaft and rotatable therewith, a second gear train (52) associated with the second output shaft and rotatable therewith, and a third gear train (30, 70) associated with the casing and rotatable therewith. A first clutch (80) is provided for interconnecting the third gear train and the first gear train to enable the third gear train to supply additional torque through the first gear train to the first output shaft when the rotational speed of the input exceeds the rotational speed of the first output shaft by a predetermined amount. A second clutch (74) is provided for interconnecting the third gear train and the second gear train to enable the third gear train to supply additional torque through the second gear train to the second output shaft when the rotational speed of the input exceeds the rotational speed of the second output shaft by a predetermined amount.
