Abstract
In a clutch friction plate of the kind comprising a hub and a pair of washers coaxial with the hub and adapted to move angularly with respect thereto against the action of spring means operable to damp the friction plate during rotation, the washers are joined together by spacer means which comprise axially-directed extensions of at least one of the washers, which extensions form a circularly continuous flange on at least one washer, and a friction disc is fastened to one of the washers in a connection region which is bounded by a circumference having a diameter which is not greater than that of the circumference around which the axial extensions are located.
Claims29
In a clutch disc assembly comprising two coaxial elements angularly displaceable relative to each other against the action of elastic means operatively interposed between said elements, a first of said coaxial elements comprising a hub and a second of said coaxial elements comprising first and second generally axially spaced washers, an axial extension from at least one of said washers joining said one washer to the other of said washers and defining a continuous axial flange at the periphery of said one washer, said first washer carrying a friction disc, the improvement comprising means for fastening said friction disc to said first washer disposed within the circumference of said axial flange and said friction disc freely extending radially outwardly beyond said axial flange.
A clutch disc assembly according to claim 11 or 44, wherein said friction disc is disposed axially between said washers.
A clutch disc assembly according to claim 1 or 39, wherein said elastic means comprise a circumferential array of coil springs received in tangential windows defined in said washers.
