Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a vehicular wheel capable of exerting stably silencing performance.SOLUTION: A vehicular wheel 10 is provided with a tire air chamber that is formed when a tire is mounted on a rim 11 and a plurality of sub air chambers 13 that are communicated with each other through communication holes 14 and function as helmholtz resonators, where each of the sub air chambers is formed by partitioning a hollow space 16 formed inside the rim 11 with partitioning members 17 in a wheel circumference direction X, and one ends of the communication holes 14 are opened toward the wheel circumference direction X on end faces of the partitioning members 17 facing the sub air chambers 13 and the other ends of the communication holes 14 are opened toward the end faces of the partitioning members 17 facing the tire air chamber.
【課題】安定した消音性能を発揮することができる車両用ホイールを提供する。【解決手段】リム11にタイヤを取付けた際に形成されるタイヤ空気室と、連通孔14を介して連通し、ヘルムホルツレゾネータとして機能する副気室13を複数備える車両用ホイール10であって、前記副気室13のそれぞれは、前記リム11の内部に形成された中空状空間16を仕切り部材17によってホイール周方向Xに仕切ることで形成され、前記連通孔14の一端は、前記副気室13に臨む前記仕切り部材17の端面でホイール周方向Xに向いて開口し、前記連通孔14の他端は、前記タイヤ空気室に臨む前記仕切り部材17の端面に開口していることを特徴とする。【選択図】図3 |
