Abstract
A hybrid V-belt (4) has at least one tension carrier (2) and a plurality of blocks (6). The blocks function as support elements and are mounted on the tension carrier. The at least one tension carrier (2) comprises elastomeric material and is reinforced with a cord insert (12). The surfaces of the tension carrier (2) are transversely ribbed or undulated and are provided with cover layers (14, 16). To increase the fatigue strength of such hybrid V-belts, the cord insert (12) is, according to the invention, arranged directly on the lower radially inner cover (14). A direct contact between the cord ply (12) and the radially inner cover layer (14) results in the region of the zeniths (6a, . . . ) of the lower block slot flanks.
