Abstract:
A power transmission apparatus for a four-wheel drive vehicle, comprising:a transfer disposed on a rear side of a transverse layout front engine, through which a driving force output from a transmission coupled with the transverse layout front engine is distributed to front and rear wheels, said transfer comprising: a pair of direction-changing gears for changing from a first transmission direction of the driving force by substantially ninety degrees to a second transmission direction of the driving force; a first gear provided and rotated about an axis extending in the second transmission direction; a second gear meshed with said first gear and rotated around an axis in parallel with the second transmission direction and having a through hole at a center thereof; an output shaft rotatably inserted through the through hole of said second gear for transmitting the driving force to a propeller shaft; and an electromagnetic clutch disposed on the axis of the second gear and between said transverse layout front engine and said second gear and arranged to control a transmission torque of the driving force between said second gear and said output shaft.
