FEDERDRUCK-LAMELLENKUPPLUNG FÜR KOMPRESSOREN

The invention relates to a spring pressure multiplate clutch for compressors, composed of two clutch assemblies, of which the one clutch assembly has a drive and an inner plate arrangement which is connected thereto, and the other clutch assembly is connected to a compressor shaft and has a hollow, finger-like cut-away clutch housing part with an associated outer plate arrangement and a disk-shaped end part which is aligned toward a compressor housing and belongs to the clutch housing part, wherein the other clutch assembly is assigned an annular shift piston, to which compressed air can be supplied. The aim is to ensure the torque transmission from the drive to the compressor shaft in a targeted space-saving manner. The solution consists in that the compressor shaft (3,6,43) is assigned continuously to the two clutch assemblies (21,22), and a sleeve-shaped inner body (12) is integrally formed on the drive (2), which is independent of the compressor shaft (3,6,43), which inner body (12) is rotatably mounted on the compressor shaft (3,6,43) and to which inner body (12) the inner plate arrangement (11) is fastened. The clutch housing part (13) is in engagement with a hub (15) which is fastened to the compressor shaft (3,6,43), between which hub (15) and the end part (18) a pre-tensioned spring arrangement (16) is provided, wherein the end part (18) is arranged so as to be situated opposite the shift piston (5) by means of an axial plain bearing (20), which shift piston (5) is integrated in an annular groove (27) in the compressor housing (4) and is mounted so as to be axially movable counter to the pre-tension of the spring arrangement (16) so as to produce contact with the end part (18) for the compressed-air-controlled axial movement (37) of the clutch housing part (13).
