ABSTRACT:
A torsional vibration damper assembly for extended travel of the damping assembly where the assembly is utilized in the limited space found in a housing of a torque converter between the forward converter housing wall and the turbine shell. The damper assembly is compact with an internal splined connection to the turbine hub and having an annular clutch plate secured to the periphery of the damper assembly to engage the other clutching components for a lock-up clutch. Three floating equalizers are journalled on a hub plate, with each equalizer and the hub having three radial arms, and damper springs in groups of four are positioned between the hub arms and/or equalizer arms. A spring retainer housing provides the torque input from the torque converter housing and has three pairs of axially aligned drive straps in the path of the damper springs.
