ABSTRACT:
An automatic clutch consisting of a centrifugally actuated pressure plate apparatus axially moveable relative to a clutch inner hub and rotationally coupled to a clutch outer basket. As the engine spins the clutch outer basket, the rotational coupling between the clutch outer basket and the centrifugal pressure plate causes the centrifugal pressure plate to move axially relative to the clutch inner hub and apply a force to driven clutch plates and driving clutch plates. The force exerted by the centrifugal pressure plate upon driven clutch plates and driving clutch plates causes the plates to couple, forcing engagement between the engine and transmission. Optionally, a variable spring tension may be applied through the clutch release mechanism to adjust the engine speed at which the clutch begins to engage.
