Abstract:
A centrifugal clutch comprising:a rotatable output driven member;two drive plates;at least one clutch disc disposed adjacent to said drive plates, 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 plates, said drive hub includes two attachment posts and at least two adjustment holes associated with each of said attachment posts;two weighted members pivotally mounted to said drive hub; andtwo torsion springs, each torsion spring operative between said drive hub and respective ones of said weighted members to bias each of said weighted members to a normally disengaged position relative to said drive plates, said torsion springs are mounted concentrically about respective attachment posts, each of said torsion springs having a first end selectively movable between said adjustment holes;wherein rotation of said drive hub causes said weighted members to pivot by centrifugal force against respective ones of said torsion springs to an engaged position thereby urging said drive plates into engagement with said clutch disc such that said driven member rotates with said drive plates.
