Abstract
A spring-engaged wet clutch assembly, particularly suitable for a vehicle main clutch, comprises a stack of interleaved clutch members biassed into engagement by a Belleville spring. The clutch assembly includes hydraulic means for disengaging the stack. Interposed between the engagement Belleville spring and the stack is a further Belleville spring or springs which the engagement Belleville acts against, and which provides progressive engagement of the clutch and also allows less powerful hydraulic means for disengaging the clutch to be used.
