Abstract:
1. A transmission comprising: an input shaft; an output; a first intermediate shaft; a second intermediate shaft concentric with the first intermediate shaft; a dual clutch assembly selectively engageable to couple the input shaft with one of the first and second intermediate shafts; a countershaft; an idler shaft; a first selectable set of gears selectively connectable for common rotation with the first intermediate shaft and intermeshing with a first set of gears connected for common rotation with the countershaft to form a first plurality of co-planar gear sets; a second selectable set of gears selectively connectable for common rotation with the second intermediate shaft and intermeshing with a second set of gears connected for common rotation with the countershaft to form a second plurality of co-planar gear sets; a first gear connected for common rotation with the second intermediate shaft and intermeshing with a first selectable gear selectively connectable for common rotation with the countershaft to form a first co-planar gear set; a second gear connected for common rotation with the second intermediate shaft and intermeshing with a second selectable gear selectively connectable for common rotation with the idler shaft to form a second co-planar gear set; a third gear connected for common rotation with the idler shaft and intermeshing with a fourth gear connected for common rotation with the countershaft for transferring torque from the idler shaft to the countershaft; and a transfer gear connected to the countershaft for transferring torque from the countershaft to the output.
