Abstract:
1. A plate-link chain for belt-driven, conical pulley transmissions, said plate-link chain comprising: a plurality of plate links arranged one behind the other in several rows arranged next to one another transversely to a longitudinal direction of the plate-link chain and that overlap transversely to a chain running direction and that are connected by pins that penetrate the plate links transversely relative to the longitudinal direction, wherein each plate link is penetrated by two pins, one of which is supported on a forward inner side of a plate link opening in the longitudlnal direction of the plate-link chain and the other is supported on a rear inner side of plate link opening in the running direction of the plate-link chain, which plate links are drawn from one of two kinds of plate links that are assembled to form the chain, whereby plate links of one kind are longer in the longitudinal direction of the plate-link chain than are those of the other, shorter kind, the distance between the forward and the rear inner sides of the plate link openings of the longer plate links is greater than that of the openings of the shorter plate links, and the longer plate links each have an extension in the longitudinal direction at one of their longitudinal ends such that the extension overlaps an adjacent shorter plate link with which a longer plate link is connected in the longitudinal direction of the plate-link chain through an intermediate arrangement of an additional longer link, wherein pairs of side-by-side longer plate links have extensions that extend in opposite longitudinal directions.
