Abstract: A clutch device for a motor vehicle includes a disc pack and an actuation device. The disc pack includes an outer disc pack and an inner disc pack arranged. The actuation device includes a retaining element, a primary piston, a secondary piston and a spring element. The primary piston and the secondary piston are each arranged on the retaining element in an axially displaceable manner and delimit respective pressure chambers. The spring element is integrally formed with the secondary piston and connects the primary and secondary pistons. When a pressure is applied to a pressure medium in the primary pressure chamber, the primary piston is arranged to move the outer disc pack against the inner disc pack and frictionally transmit torque. When a pressure is applied to a pressure medium in the secondary pressure chamber, the secondary piston is arranged to move the primary piston against the outer disc pack.

Abstract: A dual clutch transmission for a motor vehicle power train for selectively coupling rotating transmission members includes a base assembly, a bearing mounted rotating assembly which is rotatable with respect to the base assembly, first and second torque transmission assemblies movable between disengaged and engaged positions, and first and second actuation mechanisms associated with the first and second torque transmissions assemblies. The actuating mechanisms are arranged for moving the respective torque transmission assemblies between the disengaged and engaged positions for selectively coupling the transmission members. The first torque transmission assembly couples two rotating members in the engaged position. The first actuating mechanism includes a hydraulic actuating mechanism having a piston chamber and a piston for moving the first torque transmission assembly between the disengaged and engaged positions. The piston chamber is arranged in the base assembly, and the piston actuates the first torque transmission assembly in the rotating assembly.
