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.

Abstract: Spring pack for a clutch arrangement of a motor vehicle drivetrain. The spring pack has a first ring element, has a second ring element and has a multiplicity of individual springs which are coupled to the first and the second ring elements such that the first and the second ring elements are movable relative to one another in an axial direction in a manner coupled by the springs. The first and the second ring elements each have an inner circumferential section and an outer circumferential section. At least one of the first and the second ring elements has, in the region of at least one of its inner circumferential section and its outer circumferential section, a multiplicity of radially deformable elements which are designed so as to enable the spring pack to be centered in relation to a ring surface or so as to enable the spring pack to be mounted captively on the ring surface.

Abstract: A drive train for a motor vehicle has an internal combustion engine and a hydraulically shiftable transmission unit. The input of the transmission can be connected via a clutch arrangement to a crankshaft of the internal combustion engine. The output of the transmission can be connected to driven wheels of the motor vehicle. The crankshaft is connected to a pump shaft which drives a pump arrangement for a hydraulic arrangement, by means of which the transmission unit is shifted and/or lubricated. The pump shaft is connected to an electric machine. The pump shaft is connected to the crankshaft via a constrained motion mechanism. The electric machine is arranged in the axial direction between the constrained motion mechanism and a pump of the pump arrangement.
