Abstract
A power takeoff unit with torque bias capable center differential construction for four-wheel drive which includes a planetary center differential connectable to an input shaft from a transmission, the gear arrangement includes at least three nested gear components for interconnecting the input shaft with both a rear drive transfer mechanism and a planetary final drive for full-time drive such that input torque to the power takeoff unit is split between the rear drive transfer mechanism and the planetary final drive in a predetermined ratio. An electronically or mechanically actuatable friction clutch surrounds a front axle differential or can be placed between the rear drive transfer mechanism and the planetary final drive. The clutch has frictionally engageable members connected to at least one of the planetary gear components in a manner such that the torque bias to the front and rear wheel drive output shafts is controlled by a torque level established between the frictionally engagable members of the clutch.
