Title
(EN) NOISE REDUCTION APPARATUS AND PNEUMATIC TIRE PROVIDED WITH SAME
(FR) APPAREIL DE RÉDUCTION DE BRUIT ET PNEU LE COMPORTANT
(JA) 騒音低減装置及びそれを備えた空気入りタイヤ
Abstract
(EN)
Provided are a noise reduction apparatus making it possible to save weight without reducing the function of securing a sound-absorbing material to an inner surface of a tire, and a pneumatic tire provided with the same. The noise reduction apparatus (10) comprises: a band member (11) comprising a thermoplastic resin formed annularly along a tire inner surface (5), and a sound-absorbing material (12) comprising a porous material bonded to the band member (11), wherein the sound-absorbing material (12) is mounted on the inner surface of the tire (5) on the basis of the elastic restoring force of the band member (11). In the noise reduction apparatus (10), at least one rib (14) extending in the circumferential direction of the band member (11) is provided on at least one surface in the thickness direction of the band member (11), wherein the rib (14) is disposed so as to be present along the entire circumference of the band member (11).

La présente invention concerne un appareil de réduction de bruit permettant d'économiser du poids sans réduire la fonction de fixation d'un matériau absorbant le son sur une surface interne d'un pneu et un pneumatique le comportant. L'appareil de réduction de bruit (10) comprend : un élément de bande (11) comprenant une résine thermoplastique formée de manière annulaire le long d'une surface interne du pneu (5) et un matériau absorbant le son (12) comprenant un matériau poreux collé sur l'élément de bande (11), le matériau absorbant le son (12) étant monté sur la surface interne du pneu (5) sur la base de la force de rappel élastique de l'élément de bande (11). Dans l'appareil de réduction de bruit (10), au moins une nervure (14) s'étendant dans la direction circonférentielle de l'élément de bande (11) est située sur au moins une surface dans le sens de l'épaisseur de l'élément de bande (11), la nervure (14) étant disposée de manière à être présente le long de toute la circonférence de l'élément de bande (11).
