ABSTRACT:
An automatic wear adjuster for a vehicle clutch actuated by a diaphragm or Belleville spring to compensate for the normal wear of the clutch friction faces during use and maintain optimum spring characteristics. The adjustment is accomplished by retaining the fulcrum surface for the spring on the pressure plate at a substantially constant position in the clutch assembly and thus maintain the installed diaphragm spring position. The fulcrum surface is provided on a separate ring operatively connected to the pressure plate and adjusted through a series of camming ramps.
