ABSTRACT:
A clutch driven disc assembly includes a ventilated support plate and friction element to reduce the build up of heat during use. The support plate includes a plurality of radially extending paddles. A pair of friction elements are secured to the opposed sides of each of the paddles. Each paddle has a plurality of generally parallel slots formed therethrough. The slots may extend generally radially or generally circumferentially relative to the paddle. Each of the friction elements includes a corrugated backing plate having a friction facing secured thereto. The corrugations define a plurality of raised channels in the backing plate. The raised channels are formed such that they are aligned with the slots formed through the support plate when the friction elements are secured to the paddle. Such alignment provides a plurality of channels for the passage of air therethrough as the driven disc assembly rotates during use. Such air flow is helpful in cooling the friction facings when the clutch is engaged and disengaged.
