Plate-link chain for a motor vehicle drive system

A plate-link chain for a motor vehicle drive system, said chain comprising:

• a plurality of link plates hingedly connected with each other by rocker members, wherein the rocker members extend transversely to the longitudinal direction of the plate-link chain and are positioned in openings in the link plates, curved contact surfaces located on the rocker members and on the link plates and along which the rocker members and link plates are in contact with each other to transmit power, curved rolling surfaces located on the rocker members and along which the rocker members roll against each other to transmit power, wherein the rocker members are shaped asymmetrically in cross section in a height direction of the rocker members that is perpendicular to the longitudinal direction of the plate-link chain, wherein the contact surfaces between the rocker members and the link plates each have upper and lower contact surface regions in the height direction of the rocker members, and wherein the rocker members include at least two contact regions having different curvatures in the regions of their rolling surfaces.
