Belt for suppressing skipping in personal sports and industrial applications

An endless belt, e.g., for use in electric bicycles and other personal sports systems, such as standard bicycles, wheelchairs, scooters (including electric scooters), and other systems that utilize belts to transfer power to move the systems. The belt is particularly suited for suppressing "skipping" during use, having a curvature coefficient of no greater than 0.01%, in some embodiments of less than 0.005%, and having a compressibility coefficient of no greater than 0.00075. The belt may use reinforcing cords, such as carbon cords, some of which, when incorporated into the final belt, have an open porosity of 10% by volume or less, in some embodiments of 5% by volume or less. 环形皮带，例如用于电动自行车和其它个人运动系统，如标准自行车、轮椅、滑板车(包括电动滑板车)以及其它利用皮带来传递动力以使得系统运动的系统。该皮带特别适合用于在使用过程中抑制"跳齿"，具有不大于0.01％的曲率系数，在某些实施例中小于0.005％，并有不大于0.00075的压缩系数。皮带可以使用增强帘线，例如碳帘线，当包含至最终皮带中时，一些帘线具有10体积％或更低的开口孔隙率，在一些实施例中为5体积％或更低。
