Abstract: A drive belt for continuously variable transmission for motor vehicles is provided with two pulleys, each including two substantially conical pulley sheaves, between which the drive belt can be held at a variable radial position, which drive belt is provided with transverse elements (32), which on both lateral sides are provided with a flank (40) that is intended for frictional contact with the pulleys, and which, at least in its height direction, i.e. radially relative to the pulleys (1, 2), is provided with a convex curvature, in which flank (40) one or more grooves (41) are provided.

Abstract: A composite driving belt provided with a carrier and a plurality of transverse elements assembled slidably thereon, the carrier including one or more bands, preferably composed of a plurality of endless metal bands disposed radially around each other, each element being provided with a radially outward directed carrier contact plane for contacting a radial inner contact plane of the carrier while in operation, wherein the contacting plane of the transverse element is shaped by an substantially flat surface, while the inner contacting face of the carrier contacting the contact plane the element has a profiled surface, the combined roughness Ra? of both surfaces being more than 0.6 ?m, preferably over 0.75 ?m. In particular the roughness and shape of the relevant contacting faces of a belt are adapted to achieve a boundary lubricating condition, while the lubricating oil is defined to meet the requirements of prohibiting the occurrence of scratch, at least reducing the urging thereof considerably.
