Abstract
A friction coupling assembly includes: a ball ramp assembly (2) with two coaxial discs (6, 7), wherein the faces (8, 9) of the two discs (6, 7) each have ball grooves (12, 13) of increasing depth, wherein pairs of opposed ball grooves hold balls to axially support the two discs (6, 7); a plate package (3) arranged coaxially relative to the discs (6, 7) and having outer plates (24) for fixing to a coupling carrier (40) and inner plates (25) for fixing to a coupling hub (56); and a plate spring (5) for introducing force into the plate package (3), the plate spring (5) is arranged coaxially relative to the discs (6, 7), is axially pretensioned and, functionally, is arranged in series with the plate package (3).
