摘要： Transverse element (63) for a drive belt for a continuously variable transmission, which element is provided with a recess (64) with a nominal height Hn for at least partially accommodating a set of rings (61) of the drive belt and with a tilting region (70), which forms a transition between a top part of the transverse element (63) with a substantially constant, nominal thickness Dn of the transverse element (63) and a bottom part thereof, the thickness of which decreases in the radially inward direction to a smallest thickness Dm of the transverse element (63), for which purpose a first main plane of the transverse element (63) is oriented at an acute angle ϑ with respect to a second main plane. The nominal thickness Dn, the smallest thickness Dm, the nominal height Hn and said angle ϑ are matched to one another in such a way as to prevent two or more of the transverse elements (63) becoming jammed together during the drive belt manufacturing process.

摘要： Drive belt (3) for power transmission between two adjustable pulleys (1, 2) of a continuously variable transmission comprising a number of relatively thin metal transverse elements (32) slideably provided on two endless carriers (31; 31a, 31b) that each comprise a laminated set of mutually nested flat and thin metal rings (30), which transverse elements (32) comprise a top part (33) and a bottom part (35) mutually connected by a pillar part (34) of the transverse element (32), with a laterally open slot (36) being defined on either axial side of the pillar part (34) for respectively receiving one of the endless carriers (31; 31a, 31b), and which transverse elements (32) are provided with longitudinally protruding stud (38) and with a complementary hole (39). The drive belt is provided with urging means for providing at least one of the endless carriers (31; 31a, 31b) with at least a tendency to move in axial direction towards the pillar part (34) of the transverse element (32) during rotation of the belt (3) in the transmission.
