Method and device for determining the wear state of a switch coupling

摘要

#CMT# #/CMT# The method involves determining a wear condition of a shifting clutch (1) from parameters of a clutch release path and a release force at a clutch release bearing (5) of the clutch. A difference between the clutch release path at an increase-point of the release force and at a reference point represented by another increase point of the release force when the clutch is actuated, is measured. The wear condition of the clutch is measured when an internal combustion engine (3) is started and the clutch is actuated. #CMT# : #/CMT# An independent claim is also included for an arrangement for determining a wear condition of a shifting clutch. #CMT#USE : #/CMT# Method for determining a wear condition of a shifting clutch of a motor vehicle for interrupting a force flow or equalizing rotation speed between a drive output shaft of an internal combustion engine and a drive train. #CMT#ADVANTAGE : #/CMT# The method ensures absolute determination of the wear condition of the shifting clutch in a reliable manner for fast and complete interruption of the force flow between the drive output shaft of the internal combustion engine and the drive train at small mass inertia moment. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a strong schematic block diagram of a motor vehicle with a shifting clutch. 1 : Shifting clutch 2 : Output shaft 3 : Internal combustion engine 4 : Drive train 5 : Clutch release bearing 6 : Reinforcement unit 7 : Coupling pedal.
