  • Patent number: 4191285
    Abstract: An automatic wear compensator for the clutch friction faces of a diaphragm or Belleville spring-actuated clutch for an automotive vehicle to maintain optimum spring characteristics and uniform clutch release lever and bearing position through the utilization of a rotatable cam ring positioned on the backside of the clutch pressure plate and several levers pivotally mounted in slots in the pressure plate. One end of each lever is adapted to engage the clutch flywheel and the opposite end of the lever operatively engages a projection on the cam ring, with the spacing between the flywheel and the pressure plate determining whether the levers are pivoted to rotate the cam ring.
