Title: Power transfer device for four-wheel drive vehicle

Abstract

A power transfer device is described for a four-wheel drive vehicle having a transmission drivingly connected to a prime mover of the vehicle and having a set of front road wheels and a set of rear road wheels adapted to be driven from the transmission. The transfer device comprises: a first differential of the bevel gear type including a differential case arranged to be applied with drive torque from the transmission, a pinion gear rotatably mounted within the differential case, and a pair or side gears rotatably mounted within the differential case and in mesh with the pinion gear; a first output shaft connected to one of the side gears for driving the front or rear road wheels; a second output shaft connected to the other side gear for driving the rear or front road wheels; a second differential of the planetary gear type including a differential carrier formed to contain the differential case therein; and a selector mechanism arranged to selectively provide a drive connection between the second output shaft and the rear or front road wheels or a drive connection between the differential carrier and the rear or front road wheels.
