Patent ID: 7357742

Claim:
A plate-link chain for a conical disk transmission, said plate-link chain comprising: a plurality of links that extend transversely through the plate-link chain, a plurality of rocker pressure member pairs that are arranged one pair after another pair in rows relative to the transverse direction of the plate-link chain, whereby each link is penetrated by two rocker pressure member pairs, one pair following after the other pair in the longitudinal direction of the plate-link chain, each rocker pressure member pair penetrating at least two links of different rows of links offset relative to each other in the longitudinal direction of the plate-link chain, wherein first surfaces of rocker pressure member pairs that face away from each other in the longitudinal direction of the plate-link chain are in contact with oppositely-facing end surfaces of inner openings of links that are offset from one another, wherein second surfaces of the rocker pressure members of a rocker pressure member pair that face each other and form include rolling surfaces upon which contacting rocker pressure members roll against each other when the plate-link chain assumes a curved shape, and lateral end faces of the rocker pressure member pairs are adapted for contact with conical surfaces of conical disk pairs, wherein the rolling surfaces of the rocker pressure members are formed as freeform surfaces having a varying radius of curvature so that changes in a distance between centers of transverse cross sections of rocker pressure members rolling against one another during a mutual tilting of links following one after the other in the longitudinal direction of the plate-link chain are reduced.
