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.

Abstract: A drive belt having a main body formed of an elastomeric material, preferably a v-belt or v-ribbed belt, the drive belt including a top layer as belt backing, a power transmission zone having two or more tensile strands as strength members, and also a substructure optionally provided with some profiling preferably having a v-shape or a v-rib profile. The strength members are formed of cords made of mutually twisted plies (final twist), the plies being in turn twisted out of individual yarns (first twist). The cords consist essentially of polyethylene terephthalate (PET) and of two plies, the number of turns introduced into the plies twisted into a cord (final twist) and the number of turns introduced into the yarns twisted into a ply (first twist) differing by not more than 10 turns per meter (t/m).

Abstract: Disclosed is a V-ribbed belt comprising a profiled driving side that has a PK profile and is designed to transmit force to mating pulleys, and a substantially smooth rear side opposite the driving side; the coating of the V-ribbed belt has a thickness of more than 1.5 mm, and the elastomer mixtures of the base (1) and the coating (2) contain EPM and/or EPDM and the coating is essentially formed without fibres.
