Abstract
A wear take-up device in the path of force transmission between the pressure plate and the force-exerting arrangement includes at least one take-up element, which can be shifted to compensate for wear; a blocking element with a detection section which can come to rest against a stop fixed to the housing upon the occurrence of wear and which can move with respect to the pressure plate; and a wedge-like arresting element, which is pretensioned by a pretensioning arrangement toward a state in which the detection section is arrested and thus prevented from returning to its previous position. A retaining device opposes the pretensioning action of the pretensioning arrangement at least under the conditions in which the detection section has essentially not been moved out of an arrested position with respect to the pressure plate.
