Abstract A shock-absorbing torsionally elastic single or multiple V-belt or V-ribbed belt power transmission friction drive assembly is described having: a plurality of sheaves, at least one of which is shock-absorbing and includes; a rotatable hub having at least two lugs protruding radially therefrom; a rotatable rim with at least two radially inwardly extending ears adapted to matingly engage the lugs of the hub, and having a peripheral surface configured to engage the belt, resilient cushions interposed between the lugs and ears, comprised of high hysteresis elastomeric material; and an endless power trans- mission belt trained about the sheaves in driving relation in serpentine configuration. This is used to absorb torsional shocks and minimize heat build-up.
