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