Abstract (en)
[origin: WO2014019808A1] The invention relates to an automated double-clutch gearbox for commercial vehicles with a double clutch (64), a main gearbox (2), a range group (6) and two layshafts (14, 16), wherein the double clutch (64) consists of two clutches (62, 68) and each clutch (62, 68) is connected to a respective gearbox input shaft (60, 66), wherein the second gearbox input shaft (60), which is connected to the second clutch (68), is formed as a hollow shaft and runs coaxially with the first gearbox input shaft (66), which is connected to the first clutch (62), wherein the main gearbox shaft (76) is arranged coaxially between the first gearbox input shaft (66) and the output shaft (40), wherein the main gearbox (2) consists of a plurality of forward gear planes (48, 50, 52, 54, 56) and a reverse gear plane (58), wherein all shifting elements (70, 72, 74, 76, 78) are positioned coaxially to the gearbox input shafts (60, 66) and the reverse gear plane (58) adjoins the range group (6), wherein shifting for a direct drive (G5, G11) is performed via an independent one-sided shifting element or is implemented via a common shifting element (74) with the three shifting positions: left gear plane (drive output constant) (56), right gear plane (reverse constant) (58) and direct drive (G5, G11), by connecting the input shaft (66) to the gearbox main shaft (76).
