In a low-vibration V-belt ( 2 ), consisting of at least one load carrier ( 4; 4 a, 4 b) and a plurality of support elements ( 6 ) located thereon, the damping effect is improved. The formation of the damping elements ( 34 ) in a radial direction above the central section and in the direction of the width of the belt substantially symmetrical to the axis of symmetry of the support element ( 6 ) allows both possible transversal vibrations to be simultaneously damped. The damping elements ( 34 ), which consist preferably of elastomer and have high inherent damping properties, can be seated in recesses or bores ( 36 ) of the support elements ( 6 ). The rear faces of the support elements ( 6 ) can have cylindrical counterforms ( 38 ), which correspond in shape and position to the convex damping elements ( 34 ) located on the respective front faces. The edges of the convex parts ( 34 ) have radii or chamfers which permit the corresponding counterparts ( 34, 38 ) to engage without force or impact. The V-belt can be used for the continuously variable speed and torque conversion in automotive applications.
