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.
