Abstract

L'invention concerne un pneu de sécurité, présentant une structure relativement simple, qui peut utiliser la jante classique et qui peut assurer la fonction de maintien de pression interne d'une cloison de séparation de manière suffisante tout en améliorant la durabilité davantage que l'art antérieur. Le pneu de sécurité (1) comprend une cloison de séparation annulaire (7) s'étendant entre deux parties de talon (3) afin de séparer l'espace défini entre le pneu (1) et la jante (8), en une chambre interne (9) et une chambre séparée externe (10), tandis que la pression interne du pneu est normale, de telle sorte qu'elle soit élargie radialement lorsque la pression interne du pneu chute, de manière à supporter la charge à la place du pneu. Sur la face externe d'au moins la partie de sommet (7a) de la cloison de séparation (7), on trouve un moyen de blocage de contact (12), qui est interposé entre la cloison de séparation (7) et la face interne du pneu, lorsque la cloison de séparation (7) est élargie radialement, de manière à bloquer au moins partiellement leur contact direct. La cloison de séparation (7) est équipée d'une partie de communication permettant d'établir la communication entre la chambre interne (9) et la chambre séparée externe (10) tout en limitant la vitesse d'écoulement.
