Problems solved by technology

[0004] Although small axial dimensions can be achieved with the dual clutch transmission described in WO 2006 / 128626, there is also a need for other dual clutch transmissions with a very short axial structure

Embodiment Construction

[0028] attached figure 1 Shown is a schematic view of the structure of the first embodiment of the dual-clutch transmission of the present invention, and the dual-clutch transmission is denoted by reference numeral 1 as a whole. The dual clutch transmission 1 has a first input shaft 10 and a second input shaft 30 arranged coaxially with one another. The second input shaft 30 is designed as a hollow shaft, the first input shaft 10 as a mandrel. Both the first clutch 3 and the second clutch 4 are arranged on the input side 2 of the dual clutch transmission 1 . The first input shaft 10 can be connected by means of the first clutch 3 to the crankshaft 5 of the engine, not shown in the figure. The second input shaft 30 can be connected to the crankshaft 5 by means of the second clutch 4 .

[0029] The first drive shaft 50 , the second drive shaft 70 and the third drive shaft 90 are all parallel to the coaxially arranged input shafts 10 , 30 . in the attached figure 1 In the di...

Abstract

The transmission (1) has an output connected with drive shafts (50, 70, 90) in a torque proof manner. A stage toothed wheel (74) with a set of toothed wheels (74a, 74b) is provided on the drive shaft (70). A loose wheel (92) of a reverse gear (R) on the drive shaft (90) is combined with the toothed wheel (74a). The stage toothed wheel is connected with a gear shift clutch (75) arranged on the drive shaft (70). The gear shift clutch is used as a single-gear shift clutch, with which the stage toothed wheel is connected with the drive shaft (70) in a torque proof manner.

Description

technical field [0001] The invention relates to a multi-speed dual-clutch transmission, which includes a first input shaft and a second input shaft and first, second and third drive shafts. Background technique [0002] WO 2006 / 128626 discloses such a dual clutch transmission in which three drive shafts are non-rotatably connected to an output in the form of a differential. A gear connection with an idler gear and a fixed gear is assigned to each gear position, wherein the idler gear of the respective gear connection can be non-rotatably connected via a shift clutch to the shaft supporting the idler gear. If a non-rotatable connection between the idler gear and the shaft has already been established via the gearshift clutch, the corresponding gear is engaged, so that a torque flow is established between one of the input shafts and the output. [0003] WO 2006 / 128626 discloses a dual clutch transmission with a multi-stage gear having a first gear and a second gear. The mult...
