The invention relates to a hybrid V-belt (2) that comprises at least one tension support (26 or 26a,...) and a plurality of support elements (4) having a substantially trapezoid cross-section disposed on said tension support. The support elements enclose the at least one tension support (26;...). At least one (6a,...) of the two opposite lateral surfaces (6a, 6b) of the support elements (4) is provided with a slot (24a,...) in the direction of the center area, said slot receiving at least one tension support (26a,...). The aim of the invention is to improve the radial alignment of the support elements (4) of the hybrid V-belt and the dynamic behavior at average resistance to bending change. The support element (4) that is not necessarily symmetrical is designed in such a way that the center of gravity (S) of the element (4) is located outside the area formed by the tensile cords (28) of the at least one tension support (26 or 26a,...). Preferably, the center of gravity (S) is off-set from the center of rotation when seen in the radial direction. The area in which the center of gravity (S) is off-set in the radial direction is preferably limited to 1 to 2.5 times the radius of the tensile cord. The V-belt according to the invention is useful for the positive transmission of force, especially in the automotive sector. |
