Drive belt for a continuously variable transmission, continuous band thereof and method of producing such a continuous band

摘要

A drive belt for a transmission realizing a continuously adjustable transmission ratio comprising at least one continuous band having a part, which, when in a longitudinally stretched state, shows a curvature in a direction transverse to the longitudinal direction of the drive belt (1), said curvature being of a generally arc-like shape having a stretched band radius RSB, associated with a number of cross elements, each having a contact face for interacting with a principal face of the continuous band and provided with a transverse convex curvature of a generally arc-like shape having a face radius RS. The inverse value of the face radius RS minus the inverse value (1/RSB) of the stretched band radius RSB is notionally larger than -5 m-1, preferably larger than -3.5 m-1.
