Abstract

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.
