ABSTRACT:
A transfer case is disclosed for a four-wheel drive vehicle. The transfer case includes an interaxle differential and a transfer clutch for controlling speed differentiation and torque biasing across the interaxle differential. A mode shift mechanism is provided for selectively coupling one or more components of the interaxle differential to the input shaft for establishing a full-time four-wheel drive mode, a locked four-wheel drive mode, and a Neutral mode. A controller controls actuation of the transfer clutch and the mode shift mechanism in response to a mode signal indicating which drive mode has been selected by the vehicle operation.
