Abstract:
The invention relates to a drive belt (1) having a main body into which one or more tension strands (3) composed of para-aramid in cord construction are embedded, wherein each tension strand (3) has twisted plies each formed from at least one twisted yarn, and wherein the turning direction of the respective ply (first twist) is the opposite of the turning direction of the cord (final twist).
It is a feature of the invention that the tension strands (3) each have at least four plies, wherein the twist factor TM1 of the plies (first twist) is between 4.5 and 5.4, and the twist factor TM2 of the cord (final twist) is between 2.7 and 3.8, and the ratio of the twist factor of the plies to the twist factor of the cord (TM1/TM2) is between 1.3 and 1.5.
