Abstract
In a pressure plate component group for a motor vehicle friction clutch with automatic wear compensation, at least one clearance indicator arrangement is provided, which has a clearance indicator element supported on a carrier component of the pressure plate component group so as to be rotatable around an element rotational axis. The clearance indicator element has a wear readjustment area for interaction with a wear readjustment device. Further, the clearance indicator element has, on a circumferential surface, at least regionally, a thread-type surface formation, which engages, at least regionally, with a counter-surface formation on the pressure plate component group. Further, the clearance indicator element, with its thread-type surface formation, can be moved relative to the counter-surface formation so as to produce a relative movement between the thread-type surface formation and the counter-surface formation that differs from the relative rotational movement between the thread-type surface formation and the counter-surface formation that is produced by rotating the clearance indicator element around the element rotational axis. Further, a movement assembly is provided for producing the relative movement between the thread-type surface formation and the counter-surface formation.
