ABSTRACT
The driving members of the multi-spring clutch consist of a flywheel and pressure plate (both made of cast iron) with the driven plate trapped between. The pressure plate rotates with the flywheel, by means of projections on it locating with slots in the clutch cover which is bolted to the flywheel. A series of springs located between the cover and the pressure plate force the plate towards the flywheel trapping the clutch plate between the two driving surfaces. The primary (or input) shaft of the gearbox is splined to the hub of the clutch disc and transmits the drive (called torque which means turning force) to the gearbox. The drive is disconnected by withdrawing the pressure plate and this is achieved by the operation of the release levers. Figure 5.1 shows a multi-spring clutch.
