TRANSMISSION WITH CONVEX PULLEY SHEAVES AND A DRIVE BELT

摘要

The invention relates to a transverse element (11) of a drive belt 10 for a continuously variable transmission 1 provided with variable pulleys 2,3, the transverse elements (11) being provided with a tilted edge (17) , which extends between lateral sides (16) thereof and forms a transition between a top side 18 of the transverse element (11) of virtually constant thickness and an at least effectively tapering underside 15 thereof . In this transmission, both the conical surface of at least one pulley sheave of the two pulleys and the lateral sides (16) of the drive belt which come into contact therewith are provided, in the radial direction, with a convex curvature, and in this transmission, at the minimum possible radial position of the drive belt between the pulley sheave s of a pulley, a radial position of a contact point (Pl) between a transverse el ement (11) and the curved pulley sheave The invention relates to a transverse el ement (11) of a drive belt for a continuously variable transmission provided wit h variable pulleys, the transverse elements (11) being provided with a tilted ed ge (17) , which extends between lateral sides (16) thereof and forms a transit n between a top side of the transverse element (11) of virtually constant thickn ess and an at least effectively tapering underside thereof .
