Abstract
A long travel series damper assembly for a continuously variable transmission or similar arrangement which maintains minimal contact friction while equalizing manufacturing and loading tolerances without adding additional frictional forces. This assembly runs in a dry environment and includes a hub assembly having a barrel and a pair of hub drive plates encompassing the damper assembly and providing inwardly offset drive straps, a flywheel drive plate having radially inwardly extending drive arms corresponding in number to the drive straps, a floating idler divider encompassing the hub barrel and having circumferentially spaced dividers, compression damping springs located between the flywheel drive arms, the hub drive straps and the idler dividers, and at least two intermediate retaining rings, each of which is capable of movement independent of the hub assembly in one direction of rotation to limit the friction forces of the damper assembly.
