A side-bar chain for an infinitely variable cone-pulley transmission which chain includes chain links composed of individual side-bars and joint pieces connecting the links together, with each joint piece being composed of a pair of rocker pieces pushed into apertures of the side-bars, the rocker pieces having end faces extending laterally of the length of the chain for transmitting friction forces between associated friction pulley sheaves and the side-bar chain, and each rocker piece being connected with its associated side-bars by being interlocked therewith to be secured against movement in the direction of pivoting between adjacent links. Each said side-bar 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. Each rocker piece is configured to bear against a respective end web of each associated side-bar at two abutment regions spaced apart in the direction in which its associated end webs extend. The dimension of each said rocker piece in the direction in which its associated webs extend is substantially equal to the distance between its associated abutment regions. |
