Abstract

The actuation device includes a pressure medium force cylinder arrangement by means of which the friction clutch can be actuated via a release member. A measuring member of a measuring arrangement detecting an actual release is in tractive force driving engagement with an associated mating member whose position represents the actual release along a measurement path, which engagement is essentially free from play.
