Abstract
A process and a device for determining the friction lining wear in a friction clutch with a clutch housing and a pressure plate, which is arranged axially movably therein and presses a clutch disk equipped with friction linings against a flywheel of an internal combustion engine. Three detecting elements are arranged at a defined axial distance to each other, and rotate with the friction clutch and a sensor is arranged outside of the clutch housing for finding the axial position of each detecting element, whereby at least one detecting element is connected to the clutch housing and the two other detecting elements are connected to the pressure plate.
