Abstract
A friction clutch device, in particular for a drive train of a motor vehicle which is driven by internal, combustion engine, having a rotational axis, a housing, at least one pressure plate which can be displaced in the direction of the rotational axis relative to the housing for an actuation, and a spring device for loading the at least one pressure plate, in which friction clutch device the spring device has a first element for generating a pressure force which acts on the at least one pressure plate, and a second element which is separate structurally from the first element for transmitting an actuating force, in order to improve the friction clutch structurally and/or functionally.
Claims20
A friction clutch device for a drive train of a motor vehicle, comprising:
- a housing;
- a pressure plate rotatable about an axis of rotation of the friction clutch device, the pressure plate being axially displaceable relative to the housing in a direction of the axis of rotation, the pressure plate including a radial inner surface including bearing sections, the pressure plate including an axial support surface forming a supporting section facing the housing;
- a spring device for loading the pressure plate, the spring device having a first element generating a pressure force that acts on the pressure plate, and a second element for transmitting an actuating force to the pressure plate, the second element being structurally separate from the first element, the first element configured for contacting the axial support surface to force the pressure plate toward a clutch disc, the second element including at least one lever for bearing against the bearing sections of the radial inner surface of the pressure plate, the first element being a disk spring that generates the pressure force between the housing and the pressure plate;
- and
- rivets arranged on the housing, the disk spring being centered by at least one of the rivets and including an outer edge section contacting the axial support surface of the pressure plate.

- and
- a resilient pivoting bearing element arranged between the first element and the second element.
