Abstract
A torsional vibration damper comprises a plurality of arcuate centrifugal mass segments arranged within a radially outer hub ring through which a shaft extends with spring segments therebetween. The centrifugal mass segments may be interconnected in a predetermined arrangement to each other with further spring members. The resonant frequency and the stiffening behavior of the spring characteristics of the damper increase as a function of shaft speed. Additionally, the torsional vibration damper absorbs axial and radial vibrations by supporting the centrifugal mass segments with the spring segments.
