Abstract
A clutch disk assembly is provided with a continuously variable hysteresis mechanism which reduces noises or vibrations of the driving system. The continuously variable hysteresis mechanism includes a plate member, a spring member and a friction lining member operably disposed between the hub member and the disk member. The spring member is normally out of contact with said plate member to minimize wear. The spring member and plate member carry first and second projections, respectively, which come into contact after a certain amount of relative rotation occurs between those members, to produce the continuously variable hysteresis between the disk member and the hub member. The plate member is connected to the disk member in a manner preventing relative radial movement therebetween.
