Abstract

La présente invention concerne un pneu de sécurité anti-explosion à chambres multiples et un dispositif de gonflage spécial. Ces chambres sont séparées à l’intérieur du pneu interne par une paroi en caoutchouc, uniformément dans des directions circonférentielle et axiale. Chaque chambre est chargée pour être gonflée indépendamment par une valve de non-retour à pointeau. Puisqu’une seule chambre à air est divisée en chambres multiples, le danger de l’explosion de la totalité du pneu est éliminé en conséquence d’un éclatement partiel du pneu provoqué par une concentration de contraintes ou une distorsion. De plus, un dispositif de gonflage spécial peut gonfler toutes les chambres à air simultanément, et donc le procédé de gonflage est simple et efficace.
