Abstract
A clutch driven disc assembly is disclosed having coaxial damPer springs between rotary elements of the disc assembly. An auxiliary cover is combined with a main cover to drive the inner springs and to create additional drive surfaces for the outer springs. Aligned openings in the main and auxiliary covers house the coaxial springs. The covers are secured to one of the rotary elements of the disc assembly so that side walls in the main and auxiliary cover openings engage and drive both springs while the inner spring is engaged and driven only by the opening side walls of the auxiliary cover.
