Abstract

Pneumatiques à carcasse radiale métallique. Dans ce pneumatique où le talon comprend un élément de renforcement axialement extérieur composé d'une bande de tissu de câblés s'étendant radialement du niveau de la tringle jusqu'au-delà de l'extrémité retournée des nappes de la carcasse, la tringle est enveloppée dans une gaine en tissu métallique composé de câblés à torsions de meme sens, l'extrémité du pan axialement extérieur de cette gaine s'étendant radialement au-delà de l'extrémité de la partie retournée de la carcasse et de l'extrémité supérieure de l'élément de renforcement. Application notamment aux pneumatiques pour véhicules de transport lourd à carcasse radiale à une seule nappe.Tires with metallic radial carcass. In this tire where the bead comprises an axially outer reinforcing element composed of a strip of cord fabric extending radially from the level of the bead wire to beyond the upturned end of the plies of the carcass, the bead wire is wrapped in a sheath of metallic fabric composed of cords twisted in the same direction, the end of the axially outer side of this sheath extending radially beyond the end of the upturned part of the carcass and the upper end of the reinforcement element. Application in particular to tires for heavy transport vehicles with a single ply radial carcass.
