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.
Claims22
A vibration damper assembly to transmit torque between driving and driven members, comprising an input member adapted to engage torque input means, a hub operatively connected to torque output means and having a pair of diametrically opposed radial arms, a pair of equalizers journalled on and floating independently of said hub, each equalizer including a pair of equalizer plates located on opposite sides of said hub, each plate having a pair of oppositely disposed peripheral tabs, a wedge-shaped separator mounted between each pair of axially aligned tabs of a pair of equalizer plates, resilient means interposed between said hub arms and separators, and a pair of cover plates substantially enclosing said hub, equalizers and resilient means and operatively connected to said input member, each cover plate having integral drive means therein interposed in the path of said resilient means.
