Abstract
The concern is with reducing the deceleration rate of an over-running flywheel following actuation of an associated camming means, by reducing the torque of an axially biassed clutch, to provide a more reliable wheel speed analogue. In one construction the clutch may consist of two clutch discs engaging with the thrust member of a camming means. The clutch torque is reduced following expansion of the camming means by reducing the frictional engagement force between one disc and the thrust member, this being effected by a change in the mechanical advantage of a lever acting on the flywheel as the lever accommodates expansion of the camming means. In another construction the fluid pressure force on a clutch biassing piston is varied to vary the clutch torque, and in yet other arrangements, a magnetic clutch biassing force is varied.
