Side-bar chain for infinitely variable cone pulley transmissions

摘要

A side-bar chain for an infinitely variable cone pulley transmission which chain includes links composed of individual side bars and rocker pieces inserted through apertures in the side bars and connecting the links together. The rocker pieces have end faces extending laterally of the length of the chain for transmitting friction forces between associated friction pulley sheaves and the side-bar chain. Each of the side bars presents two end webs spaced apart in the running direction of the chain, extending transverse to the running direction and to the length of the rocker pieces, and each bounding a side-bar aperture. At least one of the end webs has a convex rocker surface projecting into the side-bar aperture. The rocker pieces each have a concave rocker surface extending in the longitudinal direction of the rocker pieces and bearing against the convex rocker surface with radius of curvature of the convex rocker surface of the side bar being smaller than that of the concave rocker surface of the rocker piece.
