1. A dual clutch transmission, comprising:
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 actuating piston;
a second clutch having a second input disc carrier, a second output disc carrier, a second force transfer region, and a second actuating piston;
a first partial transmission having a first partial transmission input shaft;
a second partial transmission having a second partial transmission input shaft; and
a connecting plate,
wherein the input shaft, the first input disc carrier, and the second input disc carrier are non-rotationally connected to one another,
wherein the first output disc carrier is non-rotationally connected to the first partial transmission input shaft,
wherein the second output disc carrier is non-rotationally connected to the second partial transmission input shaft,
wherein the second partial transmission input shaft is arranged coaxially to and radially surrounding the first partial transmission input shaft,
wherein the first force transfer region is arranged radially surrounding and axially at least partially overlapping with the second force transfer region,
wherein the connecting plate radially overlaps with the first force transfer region, is non-rotationally connected to the second partial transmission input shaft, extends radially from the second partial transmission input shaft, radially overlaps with at least the first force transfer region and is arranged axially between 1) the first and second partial transmissions and 2) the force transfer regions,
wherein a first actuating chamber of the first clutch is arranged on a side of the first force transfer region facing towards the input shaft and is delimited by a first wall, which is non-rotationally connected to the input shaft.
