DRIVE BELT, IN PARTICULAR A V-RIBBED BELT, HAVING IMPROVED TENSILE STRENGTH

摘要

The invention relates to a drive belt (1) having a main body made of a polymer material having elastic properties, comprising a top layer (2) as belt backing and a substructure (4) having a force transmission zone (7), wherein furthermore at least one tension strand made of aramid (3) in a cord design is embedded in the drive belt, wherein three tension strand variants are presented in more detail in said respect and wherein the tension strand made of aramid (3) has two or three strands having a ratio of the thread factor of the yarn to the thread factor of the strands between 0.7 and 2.5.
