摘要

The double-clutch transmission (1a) has a centrally arranged primary input shaft (EW1) and a secondary input shaft (EW2) designed as a hollow shaft, which is coaxially and rotatably arranged on the primary input shaft. The spur gear stages (R2 to R7) of the forward gears are arranged between the assigned input shaft and a countershaft (VW1). The input shaft sided fixed wheel (Z3) of the spur gear stage of a gear and the fixed gear (Z7) of the spur gear stage of another gear are rotationally fixed on a hollow shaft (HW1).
