ABSTRACT:
A transaxle mechanism of a four-wheel drive system for a vehicle including an engine having an output shaft having an axis of rotation laterally of the vehicle, comprising a transmission gear unit including input and output shafts each having an axis of rotation parallel with the axis of rotation of the engine output shaft, a drive gear rotatable about an axis parallel with the transmission input and output shafts and driven by the transmission output shaft, a first wheel drive gear unit comprising power splitting gear means to split driving power from the drive gear into two power components and a differential gear assembly to transmit one power component to a pair of road wheels, a second wheel drive gear unit comprising right-angle power transfer gear means engageable with the power splitting gear means and adapted to transmit the other driving power component in a fore-and-aft direction of the vehicle, the power splitting gear means constituting low-and-high speed shifting gear means to transfer driving power from the drive gear to the differential gear assembly selectively with two different gear ratios, and a driveline intervening between the power transfer gear means and another pair of road wheels and adapted to be driven by the driving power component transmitted through the transfer gear means.
