ABSTRACT:
A clutch disc assembly (1) includes a hub (2), a separate flange (5), a retaining plate (3), a clutch plate (4), a first bushing (16), a second bushing (18) and a third bushing (20). The first bushing (16) is disposed between the hub (2) and the retaining plate (3) and slidably moves against them. The second bushing (18) has a friction coefficient different from that of the first bushing (16). The second bushing (18) is disposed between the separate flange (5) and the retaining plate (3) and slidably moves against them. The friction coefficient of a portion facing to the hub (2) of the third bushing (20) is substantially identical with that of the first bushing (16), while the friction coefficient of a portion facing to the separate flange (5) of the third bushing (20) is identical with that of the second bushing (18). The third bushing (20) is disposed between the hub (2), the separate flange (5), and the clutch plate 4, and slidably moves against them.
