Abstract: A transmission belt has a body of a first elastomeric material, a plurality of cords, and a plurality of V-shaped ribs. The V-shaped ribs are arranged side by side and alternate with V-shaped grooves. The V-shaped ribs extend along the transversal axis of the belt. The belt has a first toothing and a second toothing formed by a plurality of teeth that extend obliquely to the transversal axis of the belt, thereby forming therewith respective helix (alpha, beta) angles different from 0°. Power transmission systems that include such a transmission belt are disclosed.
