Clutch facing abrasion indicator

摘要

A pressure plate for pressing the friction facing of a clutch disc to the flywheel is connected to an operating part through a mechanical link mechanism. A part to be detected which moves by the extent corresponding to the shift of the pressure plate in the clutch axial direction is disposed in the link mechanism. A contact-free sensor for detecting the part to be detected is disposed in the stationary part of the clutch, and when the clutch is connected with the abrasing facing worn to a specific limit, the sensor is designed to detect the part to be detected. There is a control part for receiving the detection signal from the sensor, and a display part is provided to tell that the control part has received the detection signal.
