Abstract

A plate link chain for a continuously variable cone pulley transmission is disclosed. The plate link chain includes a first chain link, a second chain link, and a third chain link having plates and being connected to one another by joints having rocker pins. The rocker pins have end faces configured to transmit friction forces between the plate link chain and cone pulleys, wherein at least one of the plates has at least one overlapping tip. The first, second, and third chain links form a triplet and have different plate assemblies comprised of a first plate unit or a second plate unit, each of the chain links having at least one plate positioned transversely to a running direction of the plate link chain and are repeated in the running direction of the plate link chain.
