Abstract
A high deflection amplitude torsional vibration damper for use in a torsional coupling between a driving member and a driven member, such as a clutch driven member, utilizing a unique compression spring arrangement to provide a high deflection amplitude combined with a low spring rate. The damper includes a hub receiving a driven shaft and having oppositely disposed arms, a pair of equalizers with oppositely extending arms journalled on the hub, a pair of cover plates enclosing the assembly and havng integral driving means formed therein, and a plurality of compression springs within the plates and positioned between the hub and equalizer arms. A clutch friction element may be secured to the cover plates.
