Abstract
A device for measuring wear of linings of a clutch, especially a motor vehicle clutch, with the clutch including a clutch-actuating device which has a push rod displaceable as a function of a position of, for example, a clutch pedal. A push rod includes a larger diameter portion which can be measured in a vicinity of a measurement point by means of a gauge, whereby the push rod acts upon a throwout fork which is adapted to be displaced as lining wear increases from a basic position in a direction of the push rod and indicate a need for replacement as a result of a predetermined change in diameter indicated by the group. The increased diameter portion of the push rod is formed by a frustoconical sleeve displaceable on the push rod. The sleeve is displaceable by a stop provided on a portion of a housing of the clutch when the clutch is thrown out for the first time into a fixed position corresponding to a maximum lining thickness. The sleeve is then disposed in a vicinity of the measuring point when the clutch is engaged.
