Abstract
A vibration damper assembly used in a torsional coupling between driving and driven members providing a low rate, high amplitude deflection, wherein the damper assembly includes a hub operatively connected to a driven shaft and having arms, at least one floating equalizer journalled on the hub, drive tangs connected to a driving member, and two or more groups of damper springs interposed between the drive tangs, hub arms and floating equalizers. To separate the damper springs in an equalizer, a spring separator or divider is mounted for limited arcuate movement in opposed arms of the equalizers.
Claims10
A torsional vibration damper assembly to transmit torque between driving and driven members, comprising an input member operatively associated with torque input means, a hub assembly operatively connected to torque output means and having a pair of oppositely extending radial arms, at least one floating equalizer journalled on said hub assembly, damper springs interposed between said hub arms and said equalizer, a pair of drive tangs secured to said input member and having inwardly extending projections extending into the path of and engaging said damper springs, each hub arm having a circumferentially extending slot therein receiving said drive tang projection, said equalizer providing substantially enclosed pockets for said damper springs and having axially aligned pairs of elongated windows therein, and a spring divider extending between and projecting into said axially aligned pairs of windows to separate adjacent damper springs, said windows allowing limited arcuate movement of said dividers in said equalizer.
