摘要

The assembly has an actuation ring (8) comprising an actuating surface (8a), which is axially supported on a diaphragm of a clutch to actuate the diaphragm through the actuation ring. The actuation ring is axially and slidably mounted with respect to a rotary ring (1) between an assembly position and a use position. The actuation ring is held in a thrust bearing by interference with a fixed ring (2), in the assembly position. The actuation ring is rotationally fixed to the rotary ring and released from the fixed ring, in the use position. An independent claim is also included for a clutch actuation system for a car.
