Abstract:
A damper assembly for absorbing and attenuating torsionals and vibrations transmitted from an engine to a transmission is provided. The damper assembly includes a damper flange with a plurality of spring-mass damper systems operatively attached thereto and elongated circumferentially about its outer periphery. Each spring-mass damper systems include an inner spring nestably positioned inside an outer spring, a first spring retainer having a base portion defining a first interface surface with a first pilot portion extending therefrom to define a second interface surface with a second pilot portion extending therefrom, and a second spring retainer having a base portion defining an interface surface with a pilot portion extending therefrom to define a fourth interface surface. The first and third pilot portions engage with and thereby restrict axial and radial movement of the outer spring. The second pilot portion is attached to the inner spring thereby restricting relative movement therebetween.
