Patent ID: 7811194

Claim:
A motor vehicle, comprising: a powertrain operable for generating drive torque; a driveline for transmitting drive torque from said powertrain to first and second wheels, said driveline including an input shaft driven by said powertrain, a first output shaft driving said first wheel, a second output shaft driving said second wheel and a drive mechanism coupling said input shaft to said first and second output shafts, said drive mechanism including a differential, a speed changing unit and first and second mode clutches, said differential having an input component driven by said input shaft, a first output component driving said first output shaft and a second output component driving said second output shaft, said speed changing unit having a transfer shaft driven by one of said input component and said first output component and first and second gearsets driven by said transfer shaft, said first mode clutch is operable for selectively coupling said first gearset to said second output shaft and said second mode clutch is operable for selectively coupling said second gearset to said second output shaft; and a control system for controlling actuation of said first and second mode clutches.
