Abstract
A damper-type flywheel comprises coaxial first and second flywheel parts which rotate relative to each other. There are two spaced annular flanges on the first flywheel part and an annular flange assembly on the second flywheel part which lies between the annular flanges on the first part. Circumferentially acting spring members and a friction device are operative between the first and second flywheel parts. The friction device comprises an annular flange constrained to rotate with the flange assembly, at least one friction ring disposed axially between the annular collar and the flange assembly, and lost-motion circumferential engaging portions operative between the friction ring or rings and one of the annular flanges on the first flywheel part.
