ABSTRACT:
A power transfer system is disclosed for a four-wheel drive vehicle operable for permitting a vehicle operator to select between various full-time and part-time four-wheel drive modes. The power transfer system includes a dual-planetary gear reduction unit that is operable for establishing high-range and low-range speed ratios, and a powershift mechanism that is adapted to permit the vehicle operator to shift on-the-fly for establishing full-time and part-time high-range and low-range four-wheel drive modes. The power transfer system includes an slip limiting/torque-biasing arrangement including an interaxle differential and a mode clutch operable for controlling the magnitude of speed differentiation and torque biasing across the interaxle differential.
