Pressure plate assembly, clutch disc assembly and friction clutch, in particular multi-plate clutch

A pressure plate assembly, in particular for a friction clutch, in particular multi-plate clutch, comprises a housing or carried out with an abutment arrangement (22) for common rotation about a rotational axis (A) is connected or connectable; a plate assembly (30, 32), the at least one in the housing (12) rotatable therewith about the axis of rotation (A) and with respect thereto in the direction of the axis of rotation (A) displaceably disposed plate (30, 32); an energy accumulator (34) for generating a to and through a pressure plate (30) of the plate arrangement acting pressing force, wherein the force store (34) is supported directly or indirectly on the housing (12) and on the pressure plate (30) or supported; one of the plate assembly (30, 32) associated Luftfederanordnung (600, 602), the pressing force exerted under the effect of the pressure plate (30) can be tensioned to generate an at least on the pressure plate (30) opposite to the pressure force acting elastic restoring force. According to the invention it is proposed according to one aspect of the invention is that held by the plate assembly at least one plate (30, 32) by means of the force acting through between the latter and the housing (12) Luftfederanordnung (600, 602) in the housing or at least radially and / or against relative rotation is supported. It is further proposed according to a further aspect of the invention is that the Luftfederanordnung a plurality of Luftfedern in the form of leaf springs, ...
