ABSTRACT:
In a low-vibration V-belt (2), consisting of at least one load carrier (4; 4a,4b) 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.
