Abstract: A plate-link chain for a motor vehicle drive system including conical pulleys. The chain includes a number of link plates hingedly connected with each other by rocker members. The rocker members extend transversely to the longitudinal direction of the plate-link chain and are situated in openings in the link plates. The rocker members have end faces for frictional contact with conical surfaces of disks of a belt-driven conical-pulley transmission, and the rocker member end faces are configured so that contact between the rocker member end faces and the conical surfaces of the disks takes place in the upper region of the end faces, relative to the height direction of the rocker members.

Abstract: A continuously variable power-branched transmission for a motor vehicle, including an input shaft, a variable speed drive unit having pairs of conical disks and a continuously variable transmission ratio, a gear system, and an output shaft. Two control clutches connect the variable speed drive unit and the gear system so that when going through the entire transmission ratio range of the power-branched transmission the adjustment range of the variable speed drive unit is passed through a plurality of times. The transmission also includes rotational speed sensors and a controller that determines whether a change in rotational speed is triggered by a change in the transmission ratio, and when it is not triggered by a change in the transmission ratio, the controller adjusts the variable speed drive unit so that the change in rotational speed not triggered by a change in the transmission ratio is compensated.
