CA 2278884
A transfer case for a four-wheel drive vehicle having a planetary gear assembly and a synchronized range clutch which can be selectively shifted on-the--move establishing high-range and low-range drive modes. The planetary gear assembly includes a ring gear, a sun gear, a carrier coupled for rotation with an output shaft of the transfer case, and a pinion gear rotatably supported from the carrier and which is meshed with the ring gear and the sun gear. The range clutch includes a first sleeve coupled for rotation with the ring gear and which is rotatably supported from a second sleeve coupled for rotation with an input shaft of the transfer case. With the range clutch in a first position, the first sleeve is uncoupled from the housing and the second sleeve is coupled to the carrier for driving the output shaft at a first speed ratio relative to the input shaft. With the range clutch in a second position, the first sleeve is coupled to the housing and the second sleeve is coupled to the sun gear for driving the output shaft at a second speed ratio relative to the input shaft.
