1. Hybrid dual clutch transmission, comprising:
a first sub-transmission;
a second sub-transmission;
a first clutch allocated to the first sub-transmission;
a second clutch allocated to the second sub-transmission;
a separating clutch, which couples the hybrid dual clutch transmission to an internal combustion engine, wherein the first clutch has a first force transmission region and a first outer disc carrier, the second clutch has a second force transmission region and a second outer disc carrier, and the separating clutch has a further force transmission region and a further outer disc carrier, wherein the first force transmission region, the second force transmission region and the further force transmission region are stacked radially one above the other and are arranged substantially axially overlapping, wherein the first outer disc carrier, the second outer disc carrier, and the further outer disc carrier are permanently non-rotationally connected to one another;
an electric motor, which has a rotor, a stator and a housing;
a drive element, which is permanently non-rotationally connected to the first outer disc carrier of the first clutch to link the electric motor;
at least one connection unit, which comprises at least the first outer disc carrier of the first clutch, the second outer disc carrier of the second clutch, and the further outer disc carrier of the separating clutch; and
a first bearing point and a second bearing point supporting the at least one connection unit, wherein the first bearing point is arranged axially between the first, second, and further force transmission regions and the internal combustion engine, and the second bearing point is arranged axially between the first, second, and further force transmission regions and the first and second sub-transmissions.
