Abstract

A dual clutch transmission includes an input shaft having a first clutch having a first input disc carrier, a first output disc carrier, a first force transfer region, and a first actuation piston. The transmission includes a second clutch having a second input disc carrier, a second output disc carrier, a second force transfer region, and a second actuation piston. A first sub-transmission includes a first sub-transmission input shaft and a second sub-transmission has a second sub-transmission input shaft. The input shaft, the first input disc carrier, and the second input disc carrier are connected to one another for fixedly conjoint rotation. The first output disc carrier is connected to the first sub-transmission input shaft for fixedly conjoint rotation. The second output disc carrier is connected to the second sub-transmission input shaft for fixedly conjoint rotation. The second sub-transmission input shaft is arranged coaxially with and radially surrounding the first sub-transmission input shaft.
