Abstract

A friction clutch (10) for a motor vehicle has at least two diaphragm spring means (18, 19) and a clutch control mechanism (24, 25, 26) for moving each of the diaphragm spring means between a clutch engaged position and a clutch released position. The clutch is arranged to provide for a phased engagement of the diaphragm spring means with the pressure plate so that during an initial phase of engagement of the clutch, only a first of the diaphragm spring means applies a clamp load to the pressure plate. The spring load of a second of the diaphragm spring means is applied to the pressure plate during a further phase of clutch engagement after the initial phase. There may also be an intermediate phase of clutch engagement between the initial phase and the further phase in which the full spring load of the first of the diaphragm spring means is applied to the pressure plate. The provision of such an intermediate phase results in a substantially constant clamp load being applied to the pressure plate over a given period of clutch pedal travel during clutch engagement. The invention allows a driver greater control over clutch engagement and is particularly applicable to racing cars.
