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.
