    Abstract: A center cord-line V-belt with a radially centered cord line of helically wound tensile cord embedded in a very high-modulus adhesion gum, an overcord layer, and an undercord layer. The adhesion gum has a substantially isotropic modulus, while the overcord and undercord layers have anisotropy in with-grain and cross-grain moduli. The overcord and undercord cross-grain moduli are less than the adhesion gum modulus. The anisotropic moduli are the result of oriented short fibers and the with-grain modulus is oriented axially in the belt. The adhesion gum preferably has no short fiber. The belt preferably has no reinforcing fabric layer and no fabric wrap. The adhesion gum, overcord layer and undercord layer are preferably based on an ethylene-alpha-olefin elastomer, with peroxide cure, reinforcing filler, and metal salt of an α−β-unsaturated organic acid. The belt may have notches on one or both of the inner and outer radial surfaces for additional flexibility.

    Abstract: An endless rubber power transmission belt such as a CVT belt having a main belt body with a compression portion, tension portion, an adhesion portion, and a tensile cord in contact with the adhesion portion and embedded between the compression portion and the tension portion, angled sides, and a width to thickness ratio on the order of 2 to 3. At least one of the compression portion, the tension portion and the adhesion portion has an elastomer composition that includes a saturated ethylene-alpha-olefin elastomer, a staple fiber, and a pulp fiber, or an elastomer, a high-modulus staple fiber, and a high-modulus pulp fiber. The pulp fiber constitutes less than 40% of the total high-modulus fiber amount.
