Abstract
A dual clutch transmission for a motor vehicle, including gearwheel sets that can be shifted via shift elements, which form exactly eight gear stages which are assigned to a first sub-transmission and to a second sub-transmission. Each sub-transmission is provided with a joint drive shaft. The mutually coaxial input shafts can be alternately activated via a respective power-shiftable clutch, and the even forward gears are assigned to the first sub-transmission and the odd forward shifts are assigned to second transmission which can be switched over during gear shifting by the shift elements. The dual clutch transmission is provided with an intermediate gear stage which can be switched either to the first sub-transmission, or to the second sub-transmission.
