ABSTRACT:
A two-speed segmented transfer case includes an automatic transmission side, and a transfer case side. The transfer case side having a gear reduction set, and a shift sleeve for selecting between the high, or direct drive speed, and the low, or reduced gear speed. The transmission side includes a hydraulic clutch which is used to transfer power from the transmission, to the front wheels. The hydraulic clutch is operated and controlled by the use of automatic transmission fluid that comes from the vehicle transmission. When fully engaged, the hydraulic clutch causes the power coming into the transfer case to be split between the front and rear wheels. This configuration allows for the elimination of a separate actuation system that would normally control the engagement of the clutch.
