Embodiment Construction

[0028] In the following description of the drawings, the same features are provided with the same reference numerals. If there are significant differences between individual features, this will be clearly indicated.

[0029] Figure 1 to Figure 6 The drive train 10 is shown with a drive motor (not shown), such as an internal combustion engine. The drive train 10 also has a dual clutch transmission 14 whose input shaft 16 is connected to the crankshaft of the drive motor. The dual clutch transmission 14 has a driven shaft (likewise not shown) which can be connected to driven wheels of a motor vehicle in a manner known to date.

[0030] The dual clutch transmission 14 has a dual clutch assembly 20 housed in a housing (not shown).

[0031] The dual clutch assembly 20 includes a first friction clutch 24 and a second friction clutch 26 . The two friction clutches 24 , 26 are arranged radially one inside the other, wherein the first friction clutch 24 is positioned radially on t...

Abstract

The invention relates to dual-clutch assembly (20) for a dual-clutch transmission (14), comprising an input shaft (16), a first friction clutch (24), a second friction clutch (26), a first output shaft (32), a second output shaft (42), a first piston / cylinder assembly (60), and a second piston / cylinder assembly (62); wherein input elements (28, 38) of the friction clutches (24, 26) are connected to the input shaft (16); wherein output elements (30, 40) of the friction clutches (24, 26) are each connected to one of the two output shafts (32, 42); wherein the friction clutches (24, 26) can each be actuated by means of one of the piston / cylinder assemblies (60, 62); wherein each piston / cylinder assembly (60, 62) has a piston (64, 76), which is supported so as to be axially movable in relation to an associated cylinder (66, 78); wherein each cylinder (66, 78) is supported on a support (68, 80) in a region lying radially outside on the side facing away from the piston (64, 76); and wherein each cylinder (66, 78) is distanced from the support (68, 80) in a region lying radially inside on the side facing away from the piston (64, 76).

Description

technical field [0001] The present invention relates to a dual clutch assembly for a dual clutch transmission having an input shaft, a first friction clutch, a second friction clutch, a first output shaft, a second output shaft, a first piston / cylinder assembly and a second piston / cylinder assembly, wherein the input elements of the friction clutches are connected to the input shaft; wherein the output elements of the friction clutches are each connected to one of the two output shafts; wherein the friction clutches can each be synchronized by means of one of the piston / cylinder assemblies and wherein each piston / cylinder assembly has a piston supported to move axially within the associated cylinder. Background technique [0002] Such a dual clutch arrangement is known from DE 10 2008 055 681 A1. [0003] A dual clutch transmission has a dual clutch pack and two transmission sections. The transmission section is typically of layshaft configuration. A gear change without i...
