A dual clutch transmission comprises a first clutch (C1) to be engaged for setting any one of forward-traveling odd-numbered speeds and a second clutch (C2) to be engaged for setting any one of forward-traveling even-numbered speeds. The dual clutch transmission establishes a desired forward-traveling speed by alternately engaging/disengaging the first and second clutches (C1,C2). A backward-traveling drive train is adapted to be driven by engaging one of the first and second clutches. When a reverse mode is established by a mode setting means, the one of the first and second clutches (C1) is engaged to drive the backward-traveling drive train (78,75,14a) by setting a speed change manipulator (95) at a backward-traveling position, and the other of the first and second clutches (C2) is engaged to drive a fixed one forward-traveling speed drive (73,77) train by setting the speed change manipulator at a forward-traveling position. While the reverse mode is established, the backward-traveling drive train (78,75,14a) and the fixed one forward-traveling speed drive train are kept activated regardless of whether the first or second clutch is engaged.

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. |
