A dual-clutch transmission includes two clutches for respectively connecting an input shaft in a rotationally fixed manner to a sub-transmission input shaft. Two layshafts each have one output gear arranged coaxially with respect thereto. A first, second, and third forward idler gear are each arranged coaxially with respect to the one layshaft. A fourth and fifth forward idler gear are each arranged coaxially with respect to the other layshaft. One of the output gears is a larger output gear having a greater diameter or a greater number of teeth than the other, smaller output gear. The first forward idler gear forms a second gear stage, the second forward idler gear forms a third gear stage, etc. The gear stages have a decreasing transmission ratio in the order stated.

Dual-clutch transmission

A hybrid dual-clutch transmission includes a first sub-transmission and a second sub-transmission, a first countershaft, a first output gear non-rotatably connected to the first countershaft, a second countershaft, a dual clutch, which has a first clutch assigned to the first sub-transmission and a second clutch assigned to the second sub-transmission, a separating clutch and an electric motor. The electric motor is or can be coupled to the separating clutch and to the dual clutch.

Hybrid dual-clutch transmission

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.

In a torque converter device for a motor vehicle having a single-piece housing element which, for drivingly interconnecting a torque converter and an internal combustion engine, wherein the housing element forms a disk carrier accommodating at least one disk of a separating clutch which is provided for mechanically connecting and disconnecting the internal combustion engine to and from the torque converter device, the housing element is provided with at least one actuating piston receptacle forming a pressure chamber with an actuating piston disposed therein for actuating the separating clutch.
