Abstract

Official abstract text for this publication.

A continuously variable transmission belt includes rings each superimposing annular component pieces on each other's inner and outer peripheries, and plural elements attached to the rings side by side in a circumferential direction. Each element includes a neck portion. The rings are disposed on opposite sides of the neck portion. The elements contact a driving pulley and a driven pulley. A lubrication oil discharge mechanism discharges out a lubrication oil in at least one of a gap between the component pieces, and a gap between each ring and the elements. A function of discharging the lubrication oil present in a region remote from the neck portion is higher than a function of discharging the lubrication oil present in a region near the neck portion. Thereby, the rings to which the elements are attached or the component pieces of the rings restrain decline in the centering characteristic in the width direction.

First claim

Opening claim text (preview).

The invention claimed is: 1. A continuously variable transmission belt, comprising: a ring including superimposed annular component pieces; a plurality of elements that are stacked in a circumferential direction of the ring and attached to the ring, each of the plurality of elements including a base portion extending in a width direction of the ring, a neck portion extending from the base portion in a radius direction of the ring, and a ring-receiving portion that receives…
