ABSTRACT:
A clutch construction has an improved arrangement for pivotally mounting a pair of centrifugally actuated clutch shoes on the drive rotor assembly of the clutch. A backing plate and drive flange are mounted in a spaced axial relationship with respect to each other on a hub of the rotor assembly for rotation with the hub which is adapted to be mounted on a drive shaft of a prime mover. A clutch housing is rotatably mounted on the hub by a bearing ring and is driven by the clutch shoes upon a predetermined shaft speed being reached. A pair of openings are formed in the backing plate located diametrically opposite of each other and are axially aligned with a pair of similar openings formed in the drive flange. A resilient bushing is telescopically mounted in each of the backing plate and drive flange openings to provide a shock-absorbing effect between the clutch shoes pivot pins and the drive flange to prevent fracture of the drive flange. A pivot pin is telescopically mounted in each of the pairs of resilient bushings of the axially aligned backing plate and drive flange openings and projects through an opening formed in each of the clutch shoes for pivotally mounting the clutch shoe between the plate and flange.
