Abstract
A device for a clutch which is subject to wear brought about by friction, especially for motor vehicles, for signaling that a wear limit has been reached. The clutch has a pressure plate which is connected, via tangential leaf springs, with a clutch housing so as to be fixed with respect to rotation relative to it, but so as to be axially displaceable, and by way of which a clutch disk provided with friction linings can be pressed against a flywheel of an internal combustion engine. The device has two structural component parts which can be clamped against one another, one of which structural component parts is arranged so as to be movable in the radial direction. A clamping of the structural component parts can be canceled when the wear limit is reached, wherein a movable structural component part springs into another radial position and remains there.
