Abstract

Pneumatique radial pour véhicule lourd de type poids lourd ou génie civil comprenant deux couches de travail (51, 52) comprenant des éléments de renforcement métalliques formant, avec la direction circonférentielle (XX’), un angle au moins égal à 15° et au plus égal à 45°, au moins une couche de frettage (41, 42). Chaque couche de frettage comprend des éléments de renforcement métalliques (411) formant, avec la direction circonférentielle (XX’) un angle A variable selon la position axiale. Les angles Ae1, Ae2 aux deux extrémités axiales (412, 413) de la couche de frettage (41, 42) sont de même orientation et de valeurs absolues au plus égales à 10°. L’angle A a une valeur absolue maximale Am à une distance axiale du plan médian (M) au plus égale à 15% de la largeur axiale de ladite couche de frettage, Am étant au moins égal à la moyenne des valeurs absolues des angles Ae1, Ae2 plus 10°. Figure d’abrégé : figure 1Radial tire for heavy vehicle of heavy goods vehicle or civil engineering type comprising two working layers (51, 52) comprising metallic reinforcing elements forming, with the circumferential direction (XX'), an angle at least equal to 15° and at most equal to 45°, at least one layer of hooping (41, 42). Each hooping layer comprises metal reinforcing elements (411) forming, with the circumferential direction (XX’), an angle A which varies depending on the axial position. The angles Ae1, Ae2 at the two axial ends (412, 413) of the hooping layer (41, 42) have the same orientation and absolute values at most equal to 10°. The angle A has a maximum absolute value Am at an axial distance from the median plane (M) at most equal to 15% of the axial width of said hooping layer, Am being at least equal to the average of the absolute values of the angles Ae1 , Ae2 plus 10°.
