Problems solved by technology

[0003] However, since the natural frequency of the wheel for tires lightened in this way is shifted (shifted) to a lower frequency region, it is close to the natural frequency of the pneumatic tire mounted on the wheel, and as a result, resonance of the two natural frequencies occurs Problems such as increased effect and worsened road noise

Abstract

A wheel for a tire where a rim on which a pneumatic tire is mounted is connected to the outer peripheral edge a disk, and the rim is structured by a rim main body connected to the disk and rim flanges connected to both sides in the width direction of the rim main body. The disk is off-centered to the side of one of the rim flanges from the center line in the width direction of the rim. When a portion of the rim main body, from the position where the disk and the rim body is connected to the border position between the rim main body and the other rim flange, is equally divided into three sections along the rotation axis of the wheel, the closer a section of the equally divided sections to the side of the other rim flange, the thinner the average rim thickness of that section becomes.

Description

technical field [0001] The present invention relates to a wheel for a tire, and more specifically, to a wheel for a tire that is lightweight and does not worsen road noise. Background technique [0002] In recent years, along with the weight reduction of vehicles, the weight reduction of wheels for tires has also been promoted. As a method of reducing the weight, there is a method of reducing the thickness of the disc and the rim of the wheel. In the past, weight reduction was achieved by uniformly thinning the wall thickness of the wheel and rim. [0003] However, since the natural frequency of the wheel for tires lightened in this way is shifted (shifted) to a lower frequency region, it is close to the natural frequency of the pneumatic tire mounted on the wheel, and as a result, resonance of the two natural frequencies occurs The effect increases and the road noise worsens. Contents of the invention [0004] An object of the present invention is to provide a wheel fo...
