ABSTRACT:
An improved friction assembly includes a pressure plate having a plurality of axially extending vanes which extend substantially from an inner diameter to an outer diameter of the pressure plate. The pressure plate rotates about an output drive shaft. The pressure plate is enclosed in a housing and a cover, wherein the cover is contoured to partially enclose the pressure plate and to allow air to flow from outside the cover to an inner diameter of the pressure plate. A retainer assembly is positioned circumferentially about the output drive shaft. A plurality of coil springs extend radially between the retainer assembly and the cover, at least some of the coil springs being angled to urge the retainer assembly towards the pressure plate. A plurality of levers cooperate with the retainer assembly providing axial movement of the pressure plate, the pressure plate engaging and disengaging the driven disc. Rotation of the pressure plate causes air to be moved from outside the clutch cover to an inner diameter of the pressure plate, across the pressure plate, and outside the clutch.
