ABSTRACT:
A power transmitting system for a four-wheel drive vehicle has a transmission, a central differential, and a viscous coupling. The viscous coupling is provided coaxially with the central differential, and a drive shaft is provided passing through axes of the central differential and the viscous coupling. An output shaft of the transmission is operatively connected to the casing of the differential. One of the differential gears is operatively connected to rear wheels of the vehicle through the drive shaft, and the other differential gear is secured to a housing of the viscous coupling. The housing is operatively connected to front wheel of the vehicle and the hub is secured to the drive shaft.
