CONTINUOUSLY VARIABLE TRANSMISSION EQUIPPED WITH VARIABELE PULLEYS AND A DRIVE BELT HAVING MUTUALLY CONTACTING TRANSVERSE SEGMENTS

摘要

A continuously variable transmission is provided with two variable pulleys (1, 2), each pulley (1, 2) defining a range of possible running radii (Rr) for a drive belt (3) of the transmission that rotationally connects these pulleys (1, 2), wherein the smallest possible running radius (Rr-min1) at one pulley (1) is smaller than that at the other one pulley (2). The drive belt (3) includes transverse segments (5) that can tilt relative to one another while remaining in mutual contact through a convexly curved tilting edge thereof. The radius of convex curvature of such tilting edge in a part thereof that provides such contact in a range of running radii (Rr) provided by the other one pulley (2) is substantially smaller than in a part thereof that provides the said contact in a running radius (Rr) in-between the said smallest possible running radii (Rr-min1).
