Method and arrangement for determining the wear condition of a shifting clutch
Abstract:
A method of determining the wear condition of a shifting clutch (1) of a motor vehicle which is provided either for interrupting the force flow or equalizing the rotation speed between a drive output shaft (2) of an internal combustion engine (3) and a drivetrain (4). The wear condition of the clutch (1) is determined from the parameters of clutch release path (sausrück) the and release force (Fausrück), at a release bearing (5) of the clutch (1) and, for this purpose, a difference between the clutch release path (sausrück), at a first increase-point (11; 12) of the release force (Fausrück) and at a reference point (13) represented by a second increase of the release force (Fausrück), is measured when the clutch is actuated.
