Belt for continuously variable transmission

Abstract

A belt for a continuously variable transmission includes a metal element 32 having a rocking edge 40 between a main surface 38 and a slope 41 on the front side of the metal element in the advancing direction and a ring slot 35, into which a metal ring assembly 31 is fitted, between an element body 34 and an ear portion 36. The position of the center of gravity G of the metal element 32 is regulated to the outside of the rocking edge 40 and to the inside of a radially outer end 351 of the ring slot 35. Therefore, a relation Vr<Vg<Vs is established when a speed of the rocking edge 40 at an instant when the metal element 32 leaves a driven pulley is represented by Vr, a speed of the center of gravity G of the metal element 32 is by Vg, and a speed of the ring slot 35 at the radially outer end 351 is by Vs, whereby the proper range of the center of gravity G of the metal element 32 of the belt for the continuously variable transmission can be specified correctly so that the metal element 32 located at a chord portion between the driven pulley 11 and a drive pulley 6 of a metal belt 15 is prevented from being tilted and thus can be meshed smoothly with the drive pulley 6.
