Abstract
A torsional vibration damper assembly for use in a torsional coupling or clutch arrangement to provide a low spring rate, high deflection amplitude characteristic, including an input means having driving arms or straps, at least two elongated bowed coil springs, each extending through an arc of approximately 180.degree., a hub having diametrically opposed radial arms normally in axial alignment with the drive arms, and a plurality of wedges which are inserted between adjacent coils of the bowed springs to separate the springs into several operative segments. The use of the wedges provides spring segments which operate in series.
