Abstract

A dual clutch transmission includes an input shaft, 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 also 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. The transmission includes a first sub-transmission having a first sub-transmission input shaft, and a second sub-transmission having 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 conjoint rotation. The first output disc carrier is connected to the first sub-transmission input shaft for conjoint rotation. The second output disc carrier is connected to the second sub-transmission input shaft for conjoint rotation. The second sub-transmission input shaft is arranged coaxially with and radially surrounding the first sub-transmission input shaft. The first force transfer region is arranged radially surrounding and axially at least partially overlapping the second force transfer region. The transmission has a connection plate, which radially overlaps the first force transfer region, is connected to the second sub-transmission input shaft for conjoint rotation, and extends radially starting from the second sub-transmission input shaft, and which is arranged axially between the sub-transmissions and the force transfer region.
