Experimental equipment and test procedures were developed during the work which made it possible to measure the torque transmitted by dry automotive clutches, exerting a control as precise as possible on the force exerted by the push-Plate on the clutch disc. The experimental results obtained made it possible to identify the evolution of the working stroke of the throwout bearing with clutch wear and with temperature. An in-depth study was carried out with a second experimental apparatus on the evolution of the relation between the position of the throwout bearing and the force exerted by the push-plate on the clutch disc with variations in clutch disc wear, the temperature in the housing and the number of work cycles carried out by the diaphragm spring. The analysis of the data illustrated shows how fatigue of the diaphragm spring and thinning of the friction disc are largely responsible for decay in the capacity of the clutch to transmit torque during the clutch's life. Future developments in the work envisage the use of data and observations derived from the experimentation for creating a clutch identification model which takes account of the physical phenomenon highlighted and permits predictions to be made about the torque transmitted by the clutch in the various operating conditions during its working life.
