Abstract

A dual-clutch assembly for a dual-clutch transmission has 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. Input elements of the friction clutches are connected to the input shaft. Output elements of the friction clutches are each connected to one of the two output shafts. The friction clutches can each be actuated by means of one of the piston/cylinder assemblies. Each piston/cylinder assembly has a piston, which is supported so as to be axially movable in relation to an associated cylinder. Each cylinder is supported on a support on the side facing away from the piston in a region lying radially outside. Each cylinder is spaced apart from the support on the side facing away from the piston in a region lying radially inside.
