Abstract
A series vibration damper assembly which includes a control device that will allow the damper to react differently in the coast direction than in the drive direction. The vibration damper assembly includes a housing having inwardly offset drive straps, a hub having radial arms aligned with the drive straps in a static condition, a plurality of spring separators positioned between the hub arms and separating damper springs received between the hub arms. The improvement of the present invention relates to a curved bypass thrust member secured to each hub arm and projecting through two damper springs and the spring separator to abut the next spring separator and prevent compression of the two springs in the coast direction.
