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.
A clutch device for a motor vehicle, comprising an outer disc pack that is or can be coupled to an input shaft, an inner disc pack that is or can be coupled to an output shaft, which forms a disc pack with the outer disc pack, and an actuation device having a retaining element, on which a primary piston and a secondary piston are arranged in an axially displaceable manner in each case, wherein the primary piston delimits a primary pressure chamber and, when pressure is applied to a pressure medium arranged in the primary pressure chamber, can be moved against the outer disc pack with a pressure force, such that the latter is moved against the inner disc pack in such a way that a torque can be transmitted from the input shaft to the output shaft and vice versa as a result of friction between the outer disc pack and the inner disc pack caused by the pressure force, wherein the secondary piston delimits a secondary pressure chamber and, when pressure is applied to the pressure medium or a pressure medium located in the secondary pressure chamber, can be moved such that it moves the primary piston against the outer disc pack, wherein the primary piston and the secondary piston are connected to one another via a spring element, wherein the secondary piston and the spring element are an integral component.
