Abstract:
A centrifugal clutch comprising:a rotatable output driven member; at least one drive plate; at least one clutch disc disposed adjacent to said drive plate, said clutch disc mounted for rotation with said driven member; a drive hub adapted to receive a rotational input and mounted for rotation with said drive plate; at least one weighted member pivotally mounted to said drive hub, said weighted member having at least two adjustment holes; and at least one spring member operative between said drive hub and said weighted member to bias said weighted member to a normally disengaged position relative to said drive plate, said spring member having a first end selectively movable between said adjustment holes in said weighted member; wherein rotation of said drive hub causes said weighted members to pivot by centrifugal force against said spring member to an engaged position thereby urging said drive plate into engagement with said clutch disc such that said driven member rotates with said drive plate.
