Abstract
An extended travel vibration damper assembly for use in a torsional coupling such as a torque converter wherein the damper assembly is incorporated in a speed responsive lockup coupling between the impeller and the turbine of the torque converter. A rotatable member between the housing and turbine carries a plurality of speed-responsive actuated friction clutches and is connected to the driving housing of the vibration damper. Within the housing are a pair of floating equalizers journalled on a hub having a pair of radially extending arms, and spring sets are positioned between the hub arms and equalizers for actuation by the housing to rotate the hub which is operatively connected to the turbine of the torque converter.
