Abstract

A plate link chain for a motor vehicle drive system. A number of link plates are hingedly connected by pairs of rocker members that extend transversely to the longitudinal direction of the chain. Curved contact surfaces are located on each of the rocker members and link plates, along which contact surfaces the rocker members and link plates contact each other to transmit power. The rocker members also include curved pitch surfaces along which rocker member pairs roll against each other to transmit power. The rocker members are shaped asymmetrically in the height direction and about a cross section plane extending in the longitudinal direction of the chain. Contact surfaces are provided on each of the upper and lower contact surface areas in the height direction of the rocker members.
