Abstract

A hybrid dual-clutch transmission includes a first countershaft sub-transmission, a second countershaft sub-transmission, a first clutch assigned to the first countershaft sub-transmission, a first actuating chamber, a first centrifugal oil chamber, a first power transmission region, a first inner lamella carrier, and a first outer lamella carrier. The transmission also includes a second clutch assigned to the second countershaft sub-transmission, a second actuating chamber, a second centrifugal oil chamber, a second power transmission region, a second inner lamella carrier, and second outer lamella carrier. The transmission further includes a third clutch to connect to an internal combustion engine and which has a third actuating chamber, a third centrifugal oil chamber, a third power transmission region, a third inner lamella carrier, and a third outer lamella carrier. The first, second, and third power transmission regions are arranged radially stacked one on top of the other and axially at least partially overlapping.
