Abstract
A clutch disk of the type having a hub and a clutch plate operatively connected by at least two endless elastomer belts, each of which is entrained over a pair of bushings, one of which is mounted on a hub pin attached to the hub and the other of which is mounted on a plate pin attached to the clutch plate. Each of the bushings is defined by a semicylindrical side wall and a pair of flat side walls adjacent to the semicylindrical side wall and extending parallel to each other. Opposite belt runs of the elastomer belt act on the flat side walls of the bushing to forcibly rotate the bushing around the pin.
