Abstract

A hybrid dual clutch transmission includes a first sub-transmission and a first clutch allocated to the first sub-transmission, a second sub-transmission and a second clutch allocated to the second sub-transmission, a separating clutch provided to decouple the hybrid dual clutch transmission from an internal combustion engine. The first clutch has a first outer disc carrier, the second clutch has a second outer disc carrier, and the separating clutch has a further outer disc carrier. The first clutch, the second clutch, and the separating clutch are stacked radially one above the other and are arranged at least substantially axially overlapping. The transmission also includes an electric motor having a rotor, a stator, and a housing. The transmission further includes a drive element permanently non-rotationally connected to the first outer disc carrier of the first clutch to link the electric motor.
