ABSTRACT:
An endless driving belt of the kind adapted for entrainment between at least two pulleys in a V-belt continuously variable transmission, has a plurality of links; means for connecting each link to a next link to enable articulated movement of the links; a plurality of primary blocks engaging the links and positioned one each between adjacent pins; a plurality of secondary blocks disposed one each between adjacent primary blocks and radially supported by one of the pins to provide a clearance preventing engagement with the links, the primary and secondary blocks being engageable with one another; and, the secondary blocks having side surfaces for engaging the entrained pulleys and the primary blocks having side surfaces adapted to avoid engagement with the entrained pulleys, radially and outwardly directed driving forces being transmitted from a driving pulley to the secondary blocks and from the secondary blocks to the pins, the links being driven only by nonradially directed forces, whereby the radially and outwardly directed forces transmitted by the driving pulley are transmitted to the pins and not to the links, enhancing durability of the links.
