ABSTRACT:
In a thrust piece forming a component of a chain for use in a friction pulley transmission in which the chain extends around, and circulates between, pairs of pulleys mounted on associated shafts, with one pulley of each pair being a cone pulley having a conical friction face and the other pulley of each pair being a friction pulley having a friction face which is flatter than that of the associated cone pulley, the thrust piece extending substantially transversely of the length of the chain and presenting opposed end faces via which the thrust piece bears against the friction faces of a pulley pair to effect friction force transmission between the pulley pair and the chain, one end face of the thrust piece, which contacts the friction pulley of a pulley pair, is formed to present an area of contact with the friction pulley which is reduced in relation to the area of contact between the other end face of the thrust piece and the cone pulley of the pulley pair.
