Abstract
A dual clutch transmission including two sub-transmissions, each having an input shaft arranged on an input axis, an intermediate shaft and an output shaft which is the drive output of both sub-transmissions. The intermediate shaft can be connected to the input and output shafts. The transmission also has wheel planes, shifting elements, two clutches and countershafts. A first countershaft can be connected to transmission elements of all the wheel planes on the countershaft axis and a second countershaft is connected to transmission elements of at least two wheel planes. The shifting elements include at least one single shifting element, but most of the shifting elements are double shifting elements. Two shifting elements are arranged on the input axis between two wheel planes, whose transmission elements are connected to the second countershaft. Opposite sides of the intermediate shaft are respectively connected to a range group and the output shaft.
