Abstract (en)
[origin: WO2020020491A1] The invention relates to a transverse element (32) component of a drive belt (3) for use in a continuously variable transmission, which drive belt (3) comprises a number of such transverse elements (32) that are slideably included therein relative to the circumference of an endless tensile element (31) thereof. The transverse element (32) is made from carbon steel including between 0.60 and 1.2% by weight carbon and between 0.30 and 0.60 % by weight chromium. According to the invention the carbon steel further includes a relatively small amount of between 0.05 and 0.15 % by weight vanadium for remarkably and favourably enhancing the fatigue strength of the transverse element (32).
