Abstract: A countershaft transmission is provided for a motor vehicle having a prime mover. The transmission comprises a first input shaft carrying a first input gear, a second input shaft coaxial with the first input shaft carrying a second input gear, and a countershaft carrying a plurality of loose gearwheels, each of the loose gearwheels in meshing engagement with one of the input gears, respectively. A fixed gearwheel is carried by the countershaft in meshing engagement with the gearwheel on the first input shaft. A synchronizing clutch is carried by the countershaft for driving engaging one of the loose gearwheels carried by the countershaft to select a gear ratio. A first clutch is driven by the prime mover. The first clutch is releasably drivably connectable to the first transmission input shaft and the second transmission input shaft. A second clutch is interposed between the first clutch and the second input shaft for drivably connecting the first clutch and the second input shaft. A third clutch is interposed between the first clutch and the input shafts, said third clutch being drivably connectable between the first clutch and the first shaft and the second shaft, alternatively.

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.

Abstract: A gear transmission for a vehicle in accordance with the present invention forms a first speed change range by disposing a back range gear and a second range gear on an output shaft adjacent to each other, disposing a back idle gear meshing always with the back range gear and a first range gear on a coaxial rotary shaft, engaging always the back idle gear with a gear disposed on an input shaft and engaging the first range gear with the second range gear on the input shaft. Accordingly, the speed change range of each of the first and second and back ranges can be constituted by two gear trains and the length in the axial direction can be reduced as a whole. Moreover, since the back range gear is always engaged with the back idle gear and the back idle gear is always engaged with the gear disposed on the input shaft, the angle of the face advance can be increased, chamfering of gears for sliding mesh becomes unnecessary and the gear strength of the back range gear train can be reinforced.

Abstract: A change-speed transmission for a motor vehicle which includes as input shafts a central shaft supported in an intermediate plate of the transmission housing and a hollow shaft supported on the central shaft near the intermediate plate. An output shaft for the axle drive is supported in the transmission housing parallelly to the input shafts. The transmission housing is constructed two-partite or three-partite whereby a separating plane extends within the area of the intermediate plate and parallel thereto. A first group of transmission speeds is coordinated to the central shaft and is located on one side of the intermediate plate, while a second group of transmission speeds coordinated to the hollow shaft is located on the other side of the intermediate plate.
