Chain

A belt-driven conical-pulley transmission with a chain for transmitting torque said transmission comprising:

• two pairs of conical disks about which the chain passes to transmit torque therebetween, and
• a chain including a plurality of plate elements each having at least one through opening that overlaps in a first region with a through opening of a preceding adjacent plate element and in a second region with a through opening of a subsequent adjacent plate element, wherein the at least one through opening of a plate element includes a rolling surface region and a contact surface region,
• a plurality of rocker members that interconnect the plate elements and that each extend into through openings in adjacent plate elements, so that the rocker members contact at least one of a rolling surface region and a contact surface region of each of at least two adjacent plate elements,
• wherein the rocker members are in the form of pins with at least a first pin peripheral region defining a rolling surface and at least a second pin peripheral region defining a contact surface, and wherein pin rolling surfaces contact at least one of a plate element rolling surface region and a plate element contact surface region of a plate element through opening, and wherein pin contact surfaces contact at least one of a plate element rolling surface region and a plate element contact surface region of a plate element through opening,
• wherein at least one of the first region and the second region of the plate elements and at least one of the rolling surface and the contact surface of the pin circumference are centrally asymmetrical relative to each other, and
• wherein an end face contact point of a pin end face is eccentric relative to a central axis through a cross section of the pin that is parallel to a plane perpendicular to a direction of extension of the chain when the chain is in an extended state.
