ABSTRACT:
A friction clutch comprises a driving member incorporating first and second cover members joined together and forming an enclosure therebetween. Within the enclosure are a first driven plate, an intermediate pressure plate, a second driven plate and a main pressure plate. In the engaged condition these components are all clamped together by a belville spring. A release rod acts on the main pressure plate to move it against the spring and release the clutch. The main pressure plate is driven by straps from the second cover member while the intermediate pressure plate is similarly driven by straps from the first cover member. This arrangement allows the clutch to be handled in two major sub-assemblies. The first of these includes the second cover member, the spring and the main pressure plate. The second incorporates the intermediate pressure plate and the first cover member. The first driven plate has to be positioned between the first cover member and the intermediate pressure plate prior to assembly of these components. The nature of these sub-assemblies simplifies handling and assembly of the clutch into a vehicle.
