Abstract

A drive chain suitable for use in a continuously variable transmission of a motor vehicle, the transmission having two pairs of spaced drive members about which the chain passes to transfer torque from one drive member to the other. The chain includes a plurality of link elements that include spaced, side-by-side plate links. The plate links include openings in which pairs of parallel rocker members are disposed for relative rocking movement of at least one rocker member about its longitudinal axis. A method for stretching the chain is also disclosed, in which areas of some of the plate links are plastically deformed by stretching the chain before the chain is put to use.
