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 biasing clutch is operably associated with the output of the planetary gear assembly to automatically limit speed differentiation and bias the torque distribution between the outputs of the planetary gear assembly in response to excessive wheel slip.
