A plate-link chain for infinitely adjustable cone pulley drives, the link pivot elements of which, joining the individual chain links embodied by plate packets, are embodied as thrust members is disclosed. The thrust members are inserted into recesses of the plate-links, and with their end faces they serve to transfer frictional force between friction wheels and the plate-link chain. The embodiment is such that the length of the thrust members of individual links, defined crosswise to the direction of travel of the plate-link chain varies in a non-periodic sequence over the length of the chain.

A plate link chain for radially variable width pulley drives having

To reduce the noise level of chains connecting cone pulleys in variable ratio transmissions, in which chain links (1, 15, 43) are joined by rocker elements (3, 16, 44), frame bodies or frames elements (7, 8, 21, 22, 23, 30, 31, 32, 33, 46, 51, 64, 65) are positioned between adjacent hinge joints formed by the rocker elements, located transversely to the chain, the frame bodies having lateral engagement surfaces (11, 24, 25, 26, 55, 56, 57, 66, 67) located laterally adjacent to the sides of the outermost chain link elements for resilient frictional engagement with the facing surfaces of the cone pulleys (12, 40, 41) of the transmission, so that the transmission will be engaged by the engaging surfaces (45) of the rocker elements as well as the engagement surfaces of the frame bodies. The frame bodies are retained on the chain by force engagement with the chain link elements and/or the rocker elements.
