Abstract

A plate-link chain for a motor vehicle drive system. The chain includes a number of link plates hingedly connected with each other by rocker members that extend transversely to the longitudinal direction of the plate-link chain and are positioned in openings of the link plates. Curved-shaped contact surfaces are located on each of the rocker members and link plates, along which contact surfaces the rocker members and link plates are in contact with each other to transmit power. The rocker members are shaped asymmetrically in the height direction of the rocker members, relative to a cross section extending in the longitudinal direction of the plate-link chain. The link plate openings include at least one region that is curved in an inward direction, to prevent incorrect orientation of the rocker members during assembly of the chain.
