ABSTRACT:
In a power transfer mechanism including an input shaft arranged to be applied with drive torque from a prime mover of a motor vehicle, a first output shaft arranged coaxially with the input shaft for drive connection to a first set of drive axles and a second output shaft arranged in parallel with the first output shaft for drive connection to a second set of drive axles, a planetary gearset of the double pinion type is mounted on the first output shaft to transfer the drive torque from the input shaft to the first and second output shafts, the planetary gearset including a ring gear in drive connection to the input shaft, a sun gear in drive connection to the first output shaft and a planet carrier for drive connection to the second output shaft, a limited-slip differential in the form of a viscous fluid coupling is disposed between the ring gear and planet carrier to limit differential action between the first and second output shafts, and a drive train for drive connection between the planet carrier and the second output shaft is located at the rear side of the viscous fluid coupling.
