Abstract
An endless belt, for use in a variable speed transmission comprising at least one pulley having opposed conical surfaces, comprises a loop-shaped stack of I-shaped friction plates having left and right recesses, with chains located in the recesses in side-by-side relationship. Each chain comprises interleaved link plates, and the chains are out of phase with each other by one-half the pitch distance. Each friction plate is engaged, in driving relationship, in notches in the link plates of one of the two chains, and the next friction plate is engaged, in driving relationship, in notches of the link plates of the other chain. There are no friction plates which are not engaged in notches of the link plates. Consequently less pressure and improved friction are achieved. The preferred link plate comprises two separable layers formed by stamping. In one preferred embodiment, the chains comprise interleaved groups of link plates of uniform thickness, and each group consists of the same number of link plates.
