Abstract:
A driving belt for use in a continuously variable transmission comprising two V-shaped pulleys (2, 3), which driving belt (1) comprises:a carrier consisting of two endless band packages (5, 6) lying side by side, on which transverse elements (4) are disposed, wherein each transverse element (4) includes two recesses (7, 8) positioned opposite each other for receiving the band packages (5, 6), so that a first part (11) of the transverse element (4) extends under said band packages (5, 6), a second part (12) of the transverse element (4) is positioned between said band packages (5, 6), and a third part (13) of the transverse element (4) extends above said band packages (5, 6), wherein each recess includes an inside surface (21, 22, 23) facing towards the band package (5,6), a first portion (22) of the inside surface that is formed by said second part (12) of the transverse element (4) includes an acute angle (a), near the underside of the band packages (5, 6), with the plane in which the band packages (5, 6) lie, and the first portion (22) merges, through a convex portion, with a second portion (21) of the inside surface that is formed by said first part (11), the acute angle (a) being located apart from the convex portion and being defined by an intersection of a first horizontal line drawn contacting an uppermost surface of the second portion and a second line drawn tangential to the first portion at the point the first line intersects the first portion.
