Title (EN) TIRE WITH REVERSED CARCASS PLY TURNUP CONFIGURATION
(FR) PNEU A STRUCTURE DE RETOURNEMENT DE PLI DE CARCASSE INVERSEE
Abstract:
(EN) An improved track belt tire is constructed of a removable tread belt assembly mounted to the outer circumferential surface of a multi-layered tire carcass with an embedded carcass ply having ply turnup ends looped around and extending axially inwards from the bead wires. The outermost ends of the first and second turnup ends being located radially outward at a distance equal to between about 2 and 3 times the diameters of the bead wires so that the ends of the turnup ends are supported by the flange ends of the tire rim when a tire carcass mounted to the tire rim is deflected. The turnup ends are also supported by first, second, third, and fourth apex elements disposed about each of the bead wires. The ply line of the first carcass ply layer can also follow the natural ply line.
(FR) L'invention concerne un pneu à bande de roulement améliorée, constitué d'un ensemble bande de roulement-ceintures amovible, monté sur la surface périphérique extérieure d'une carcasse de pneu multinappes, dont un pli de carcasse noyé présente des extrémités de retournement entourant les tringles et s'étendant axialement vers l'intérieur à partir desdites tringles. Les extrémités les plus à l'extérieur des premières et deuxièmes extrémités de retournement sont situées radialement vers l'extérieur à une distance représentant environ 2 à 3 fois le diamètre des tringles, de sorte que ces extrémités sont supportées par les extrémités du rebord de la jante lorsqu'une carcasse de pneu montée sur la jante subit une déflexion. Les extrémités de retournement sont donc supportées par des premier, deuxième, troisième et quatrième éléments de bourrage sur tringle disposés autour de chacune des tringles. La ligne de pli de la première nappe de plis de carcasse peut également suivre la ligne de pli naturelle.
