Abstract

Abstract The clutch shown has an oil slinger comprising an annular plate pressed or snap-fitted in a groove formed in the inside surface of the conventional clutch presser plate which rotates with the engine flywheel. The plate is made of solid sheet metal in order to serve as a wall of an oil reservoir or trough. The slinger further comprises a drum having one end flange thereof secured to the annular plate and a second radially inwardly extending flange at the other end serving as the other wall of the annular oil trough. The center portion of the drum is perforated, and oil which collects in the rotating trough is thrown outwardly through the perforations under the action of centrifugal force and confined between the flywheel and annular plate, providing continuous lubrication for the clutch plates or discs, regardless of whether the clutch is engaged or disengaged.
