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.
