Dampening disk assembly

摘要

A dampening disk assembly is provided to ease a control of a friction generated by two kinds of friction generating mechanisms in a separated hub type of clutch disk assembly. A second dampening mechanism 6 is a mechanism to generate a friction between a separated flange 18 and a hub 3 when both of the portions rotate relatively. The second dampening mechanism 6 includes a bushing 19 and a fixing plate 20. The bushing 19 rotates with the hub 3 in a body. The fixing plate 20 rotates with the separated flange 18 in a body. The fixing plate 20 includes a first disk-shaped part 71 and a second disk-shaped plate 73. The second disk-shaped plate 73 generates a friction when the hub 3 and the separated flange 18 rotates relatively. The first disk-shaped part 71 generates a friction when the separated flange 18 and both a clutch plate 31 and a retaining plate 32 rotate relatively. The friction generated by the first disk-shaped portion 71 is larger than that generated by the second disk-shaped portion 73.
