Abstract
A dual clutch transmission is described having first and second input shafts and allowing at short axial length many degrees of freedom for providing various transmission ratios of the individual driving gears. A loose wheel of a reverse driving gear is provided on a third drive shaft and engages a first gear wheel of a step wheel. A fixed wheel of a second forward driving gear is provided on one of the input shafts and is engaged by a second gear wheel of a step wheel. The step wheel is switchable by a first gear shifting clutch that is provided on the second drive shaft and is designed as a first single gear shifting clutch allowing to connect only the step wheel in a rotationally fixed manner to the second drive shaft such that the step wheel co-rotates with the second drive shaft.
