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.

Abstract: A compact manual transmission includes an input shaft having four fixed input gears, a first intermediate shaft rotatably supporting two speed gears meshing with two of the input gears, a second intermediate shaft rotatably supporting three speed gears meshed with three of the input gears and a reverse gear meshed with a speed gear on the first intermediate shaft, and an output shaft. Two speed gears on each of the intermediate shafts meshes with common input gears. A transfer gear on each intermediate shaft is meshed with the output shaft. The transmission further includes a synchronizer clutch for establishing two forward gears by selectively coupling the two speed gears to the first intermediate shaft and a pair of synchronizer clutches for establishing three forward gears and the reverse gear by selectively coupling the three speed gears and reverse gear to the second intermediate shaft.

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.

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.
