Abstract
A transfer case for a four-wheel drive vehicle having a planetary gear assembly which integrates a gear reduction unit and an interaxle differential into a common assembly. A synchronized range clutch is operably associated with the input to the planetary gear assembly and can be selectively shifted on-the-fly for establishing high-range and low-range speed ratios. A synchronized mode clutch is operably associated with the output of the planetary gear assembly and can be selectively shifted on-the-fly for establishing two-wheel, full-time four-wheel and locked four-wheel drive modes.
