Patent ID: 7686722

Claim:
A plate-link chain for a belt-driven conical-pulley transmission, said chain comprising: a plurality of link plates that are articulatingly connected with each other by rocker members, wherein link plates are positioned one behind another transversely to a longitudinal direction of the plate-link chain and are offset from each other in the longitudinal direction of the plate-link chain and partially overlap each other, the plate-link chain including a plurality of link plates having two different lengths in the longitudinal direction of the plate-link chain and having openings to receive the rocker members, wherein in a short link plate rocker members are spaced from each other in the longitudinal direction of the chain at a short pitch spacing and in a long link plate rocker members are spaced from each other in the longitudinal direction of the chain at a long pitch spacing, wherein link plates in the longitudinal direction of the chain are arranged such that each long link plate is immediately followed by a short link plate, so that pitch spacings in the longitudinal direction of the chain are one of a short pitch spacing and an intermediate pitch spacing that lies between the short pitch spacing and the long pitch spacing, and so that no long link plate immediately follows another long link plate.
