Abstract: An adapter for installation between a single-offset transfer case and a transmission unit. The adapter includes an adapter input shaft coupled to an output shaft of the transmission, an adapter output shaft coupled to an input shaft of the transfer case, and a drive mechanism connecting the adapter input and output shafts. The adapter input shaft is rotatably driven by the transmission output shaft about a first rotary axis. The adapter output shaft is rotatably driven by the adapter input shaft about a second rotary axis. The input shaft and a first output shaft of the transfer case are commonly aligned for rotation with adapter output shaft for rotation about the second rotary axis. The transfer case has a second output shaft supported for rotation about a third rotary axis. Optionally, the adapter may include a torque disconnect clutch for disconnecting drive torque from the transmission to the transfer case for functions requiring torque interruption such as towing and for assisting in "on-the-fly" shifting between four-wheel high- and low-range drive modes.

Abstract: The transmission of the present invention includes a multi-speed geartrain comprised of an input shaft, a mainshaft, and a plurality of constant-mesh gearsets arranged for selectively coupling the mainshaft to the input shaft for driven rotation at various speed ratios. The mainshaft can be selectively coupled to the power transfer arrangement for establishing two alternative power transmission routes. In particular, the range shift mechanism is provided for establishing a high-range power transmission route and a low-range power transmission route from the mainshaft to a quill shaft which, in turn, drives the interaxle differential. The torque delivered by the quill shaft is split by the interaxle differential between the front and rear drivelines to establish the full-time four-wheel high-range and low-range drive modes. Optionally, the torque transfer apparatus can be provided for controlling speed differentiation across the interaxle differential or in place of the interaxle differential for on-demand four-wheel drive operation. The torque transfer apparatus can be a speed-sensitive device or an electronically-controlled transfer clutch.
