Abstract

A friction coupling assembly includes: an actuator in the form of a ball ramp assembly, a plate package, and a ball bearing. The actuator has two coaxial discs, wherein the faces of the two discs each have ball grooves of increasing depth. Pairs of opposed ball grooves hold balls to axially support the two discs. The plate package is arranged coaxially relative to the discs and has outer plates for fixing to a coupling carrier and inner plates for fixing to a coupling hub. The ball bearing is for axially supporting the at least one rotatingly drivable disc, wherein a first bearing race of the ball bearing is integrally formed with the at least one rotatingly drivable disc.
