Title (EN) ELECTRICALLY CONDUCTIVE CROWN ARCHITECTURE FOR A TYRE OF A HEAVY DUTY CIVIL ENGINEERING VEHICLE
(FR) ARCHITECTURE DE SOMMET ELECTRO-CONDUCTRICE D'UN PNEUMATIQUE POUR VEHICULE LOURD DE TYPE GENIE CIVIL
Abstract:
(EN) The present invention concerns a radial tyre (10) and, more particularly, the sidewalls (20) of same, and the tread (30) of same, with a view to minimising the temperature of the tyre while ensuring the electrical conductivity of same. The tread (30) comprises two wings (311, 312) and a central portion (32). These components rest on a base layer (33) radially inside the tread (30). The base layer (33) contains a lateral portion (331, 332) partly in contact with a tread wing (311, 312). According to the invention, this tyre crown structure, in contact with the carcass reinforcement, helps constitute a preferential conductive path for electric charges between the rim and the ground when the tyre is mounted on the rim of same and flattened against the ground.
(FR) La présente invention concerne un pneumatique radial (10) et plus particulièrement, ses flancs (20), et sa bande de roulement (30) en vue de minimiser la température du pneumatique tout en garantissant sa conductivité électrique. La bande de roulement (30) comprend deux ailes (311, 312) et une portion centrale (32). Ces composantes reposent sur une couche de base (33) radialement intérieur à la bande de roulement (30). La couche de base (33) contient une portion latérale (331, 332) en partie en contact avec une aile de bande de roulement (311, 312). Selon l'invention, cette structure du sommet du pneumatique, en contact avec l'armature de carcasse permet de constituer un chemin conducteur préférentiel des charges électriques entre la jante et le sol lorsque le pneumatique est monté sur sa jante et écrasé sur le sol.
