Abstract:
An automated dual-clutch multi-speed transmission is adapted to transfer power from an engine to the driveline of a motor vehicle. The transmission includes an output shaft adapted for connection to the driveline, an input shaft continuously driven by the engine and offset from a position substantially parallel to the output shaft. A countershaft is in constant driving engagement with the output shaft and is offset from and positioned substantially parallel to the input and output shafts. A first clutch is operable for establishing a releasable drive connection between the input shaft and a first driven shaft. A second clutch is operable for establishing a releasable drive connection between the input shaft and a second driven shaft. First and second gearset clutches are operable to releasably drivingly couple first and second gearsets to the countershaft.
