Plate-link chain for a continuously variable transmission
View Patent ↗A plate-link chain for a belt-driven conical-pulley transmission. The chain has a large number of link plates that are articulatingly connected with each other by rocker members, which link plates are positioned one behind the other and are offset from each other transversely relative to the longitudinal direction of the plate-link chain, and also partially overlap each other. The chain has a plurality of link plates of two different lengths in the longitudinal direction of the chain, with openings to receive the rocker members. The arrangement of the link plates in the longitudinal direction of the chain is such that a long link plate is followed by a short link plate.
1. 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.
2. A plate-link chain in accordance with claim 1 , wherein link plates extending in the longitudinal direction of the plate-link chain are arranged such that a short link plate is followed by one of a short link plate and a long link plate.
3. A belt-driven conical-pulley transmission having a plate-link chain in accordance with claim 1 .
4. A belt-driven conical-pulley transmission having a plate-link chain in accordance with claim 2 .
