Abstract
A chain-belt that extends between driving and driven members such as the pulleys of a continuous variable transmission wherein the chain-belt is formed of a plurality of interleaved sets of links. The links define a passageway and a plurality of load blocks are positioned in the passageway. Several members for reducing the noise produced by such a chain-belt are disclosed whereby certain of the load blocks in the chain-belt engage the pulleys at a different location to alter and reduce the pattern of noise produced by the chain-belt. The chain-belt also has links with a particular configuration that allows the links to have a short pitch length while still maintaining strength in the links.
