Abstract

La présente invention a pour objet un pneumatique, destiné à équiper un véhicule de génie civil, et concerne plus particulièrement son armature de protection. Pour augmenter la résistance aux agressions de son armature de protection, lors d’un roulage sur des pierres tranchantes, les renforts de chaque couche de protection (51) sont des éléments bidimensionnels (511) ayant chacun une section unitaire Se et deux à deux séparés, chaque élément bidimensionnel (511) est inscrit dans un disque minimal ayant un centre O et un diamètre D à la fois au moins égal à 0.1 fois L, exprimé en mm, et à 30 mm, et les centres O des disques minimaux circonscrits aux éléments bidimensionnels (511) sont positionnés aux sommets de polygones réguliers identiques, de telle sorte que les éléments bidimensionnels constituent un pavage régulier. Figure pour l’abrégé : Fig 1The present invention relates to a tire, intended to be fitted to a civil engineering vehicle, and more particularly relates to its protective reinforcement. To increase the resistance to attacks of its protective frame, when driving over sharp stones, the reinforcements of each protective layer (51) are two-dimensional elements (511) each having a unitary section Se and two by two separate , each two-dimensional element (511) is inscribed in a minimum disc having a center O and a diameter D both at least equal to 0.1 times L, expressed in mm, and to 30 mm, and the centers O of the minimum discs circumscribed to Two-dimensional elements (511) are positioned at the vertices of identical regular polygons, such that the two-dimensional elements form a regular tessellation. Figure for the abstract: Fig 1
