BELT FOR NON-STAGE TRANSMISSIONS

摘要

A belt for non-stage transmissions, wherein a first line at the lower end of the element main body of a metal element is determined and a second line which linearly connects the lower end of a V-surface to which load is applied from the V-groove in a pulley and the inner end of the saddle surface is determined, in such a manner that when a downward load is applied from a metal ring assembly to the outer end of a saddle surface, the transverse rupture strength of the element main body is latitudinally constant. The position of a recess is set adjacent a point of intersection between the first and second lines, and inside the recess the lower edge of the element main body is defined by the first line and outside the recess the lower edge of the element main body is defined by the second line. Thus, an innovative design of a shape for the lower edge of the element main body of the metal element makes it possible to enhance the durability of the metal element.
