Patent ID: 10024396

Abstract:
A dual-clutch transmission has first and second coaxial input shafts, with the second shaft extending through the first shaft. The input shafts can couple respective countershafts via input constants. The first countershaft has two sections rigidly connected by a first shifting element. Four gear stages implement forward gears and one gear stage implements reverse gears. The fourth gear stage is arranged between the first section and an output shaft. The second and third gear stages are arranged between the second section and the output shaft. The first and the reversing gear stages are arranged between the second countershaft and the output shaft. The first input constant has a loose wheel supported on the second countershaft and can be rotationally fixed, by a second shifting element, to the first section of the first countershaft. The second section can be rotationally fixed, via a third shifting element, to the second countershaft.
