V-BELT, ELEMENT FOR V-BELT, AND PULLEY FOR V-BELT

摘要

PPROBLEM TO BE SOLVED: To provide a V-belt, an element for the V-belt, and a pulley for the V-belt constituting a compact belt type continuously variable transmission capable of corresponding to high torque and reducing its weight. PSOLUTION: Each top part 24 of each projecting part 22 in a friction part 13 on both sides in the direction of width is eccentric on a shaft axis side of the pulley. Consequently, friction force between the friction part 13 and a sheave face when the element moves onto the shaft axis side of the pulley for the pulley is larger than friction force between the friction part 13 and the sheave face when the element moves onto an outer peripheral side of the pulley for the pulley. As a result, it is sufficient with small nipping force by a pair of sheaves, and it is unnecessary to increase rigidity of the pulley even when corresponding to high torque to constitute the compact belt type continuously variable transmission being light in weight.
