  • Patent number: 4998908
    Abstract: A transmission chain for a continuously variable conical pulley drive, comprising a plurality of interleaved sets of link-plates for each link, and an associated transverse-plate for each set. Each link-plate has at least two cams (43) per longitudinal side, defining between them a groove (44) with preferably V-shaped sides opening towards the cam-tops. Each associated transverse-plate has a rectangular closed window (54) and longsides (58) shaped correspondingly to the grooves (44). In service, when running through the sheaves of the pulleys, the transverse-plates locate themselves free-of-play in the grooves of the link-plates reducing wear and noise and any tendency for the chain to run out of square. At the straight trajects, play between the transverse-plates and the link-plates is restored again, permitting lube oil to enter.
