(EN) BURST-PROOF SAFETY TYRE OF VEHICLE

Abstract
(EN)
A burst-proof safety tyre (20) of a vehicle is provided. The tyre (20) comprises a tyre casing (21), a split rim (22), an L-shaped sealing ring (25), a combined support loop (23) and a valve core (24). The combined support loop (23) comprises a plurality of layers of support rings (231), which are nested layer by layer and fixed with the rim (22). The size of the support loop (23) can be increased through the combined support loop (23), and thereby the distance between the inner wall of the tyre casing (21) and the outer wall of the combined support loop (23) can be shortened under normal tyre pressure. At the moment of tyre burst, the combined support loop (23) can quickly and effectively support the tyre casing (21), and the change of the operating radius of the tyre (20) is controlled in a range as small as possible, thereby ensuring the originally basic performance of the tyre (20), preventing the accident caused by the sudden uncontrollable running direction of the vehicle and eliminating potential safety hazard. In addition, the split rim (22) is in favor of the layered mounting of the large-size combined support loop (23), and meanwhile greatly facilitates assembly and disassembly processes, so that the maintenance and replacement of the tyre (20) can be performed by common tools.
(FR)
L'invention porte sur un pneumatique de sécurité à épreuve de l'éclatement (20) pour un véhicule. Le pneumatique (20) comprend une enveloppe de pneumatique (21), une jante fendue (22), un anneau de fermeture en forme de L (25), une boucle de support combinée (23) et un noyau de valve (24). La boucle de support combinée (23) comprend une pluralité de couches de couronnes de support (231) qui sont emboîtées couche par couche et fixées à la jante (22). La dimension de la boucle de support (23) peut être augmentée par la boucle de support combinée (23), et, de cette façon, la distance entre la paroi intérieure de l'enveloppe de pneumatique (21) et la paroi extérieure de la boucle de support combinée (23) peut être raccourcie sous la pression normale du pneumatique. Au moment de l'éclatement d'un pneumatique, la boucle de support combinée (23) peut supporter rapidement et efficacement l'enveloppe (21) du pneumatique, et la variation du rayon de fonctionnement du pneumatique (20) est réglée dans un intervalle aussi petit que possible, en assurant ainsi la performance de base initiale du pneumatique (20), en évitant l'accident provoqué par une direction de roulement incontrôlable brusque du véhicule, et éliminant le potentiel de danger de sécurité. En supplément, la jante fendue (22) favorise le montage par couches de la boucle de support combinée de grande dimension (23), et cependant, elle facilite grandement les processus d'assemblage et de démontage, de sorte que l'entretien et le remplacement du pneumatique (20) peuvent être exécutés avec des outils habituels.
