Abstract
A drive unit utilizing a double planetary differential and an overdriven gear to shift torque between output shafts. The drive unit includes a motor, a differential caging housing a planetary differential and in driving engagement with two output shafts, a planetary carrier, a first gear, a second gear, and two variably engageable clutches. The planetary carrier supports the planetary differential and is drivingly engaged with a first output shaft. The first gear is capable of being overdriven and is in driving engagement with the motor and the variably engaged clutches. The second gear is in driving engagement with the motor and the differential caging. The first clutch is disposed between the first gear and the second output shaft and the second clutch is disposed between the first gear and the planetary carrier. When the clutches are actuated, torque is shifted between the output shafts via the first gear.
