ABSTRACT:
A transfer device is provided for distributing the output of a transmission to front wheels and rear wheels of the vehicle through a front power train and a rear power train. The output shaft of the transmission is operatively connected to the rear power train. The transfer device has a drive gear rotatably mounted on an output shaft of the transmission and engaged with a driven gear in the front power train, a fluid operated multiple-disk friction clutch having a drive drum and a driven drum. The driven drum is secured to the drive gear and the drive drum is secured to the output shaft. The output shaft of the transmission and the drive gear are arranged to be changed with an output shaft and a drive gear for the front power train which are engaged with each other, and an input member of the rear power train is arranged to be secured to the drive drum. Thus, the power transmitting system can be changed from the front-wheel drive based four-wheel drive system to the rear-wheel drive based four-wheel drive system.
