Abstract:
Link chain for continuously variable transmission cone pulley gearbox whose articulation pieces which connect together the individual chain links which are formed as sets of plates are constructed as pairs of rocker members inserted in apertures in the plates and having rocker faces supported against each other, wherein the rocker members are connected to the plates which make up the chain at least partially through a positive locking anti-rotation lock, the end faces of the rocker members facing the relevant cone pulley transfer friction forces between the cone pulleys and the link chain and the rocker members are secured at least in part by at least one retaining element against moving sideways out from the plate apertures, characterised in that a retaining plate is associated with at least the outer plates of the chain which determine the chain width, relative to the chain link associated with same at least on one chain side, that the retaining plate is held on the outside of the outer chain plate, that the retaining plate is fixed on the rocker members associated with the chain link with a clamping seat which leaves the rocker faces free, and that the relevant structural unit formed from at least one retaining plate and the associated rocker member has a design which allows the spacing of these rocker members to be changed in the longitudinal direction of the chain.
