ABSTRACT:
A torsional vibration dampening device suitable for a clutch to transmit torque between driving and driven members, absorbing torsional vibrations, comprises a plurality of circumferentially extending spring receiving portions defined in both a torque-input member and a torque-output member, a plurality of damper spring sets operatively accommodated in the respective spring receiving portions, and a floating spring separator being rotatable relatively to both the torque-input member and the torque-output member and having a plurality of tapered arms interposed between adjacent damper springs in each spring set and a connecting member integrally formed with the tapered arms. The connecting member is cylindrical in shape and arcuately and rotatably accommodated in an essentially cylindrical aperture axially circumferentially extending along a cylindrical outer flanged portion of the device. The tapered arms project radially and inwardly from the cylindrical connecting member.
