Summary: | The bead wire (52) for a tyre is substantially rotationally symmetric around an axis comprising several windings of at least one wire arranged axially beside one another over N layers Ci radially superimposed on top of one another. The bead wire (52) for a tyre comprises a base hexagonal bead wire (56) comprising: - radially external and internal layers (C'sup, C'inf) of N1 windings, - two axially and radially external lateral alignments (F1, F2) of N1 windings, - two axially external and radially internal lateral alignments (F3, F4) of N1 windings. The bead wire (52) for a tyre comprising a winding (E3.1, E4.1) for axial continuation of the radially internal layer (C'inf). The bead (52) for a tyre comprising an additional layer (Ca3) of N2 windings forming the radially external layer of the bead (52) for a tyre (10).
La tringle (52) pour pneumatique est sensiblement de révolution autour d'un axe comprenant plusieurs enroulements d'au moins un fil agencés axialement les uns à côté des autres sur N couches Ci radialement superposées les unes sur les autres. La tringle (52) pour pneumatique comprend une tringle hexagonale de base (56) comprenant: -des couches(C'sup, C'inf) radialement externe et interne de N1 enroulements, - deux alignements latéraux (F1, F2) axialement et radialement externe de N1 enroulements, - deux alignements latéraux (F3, F4) axialement externe et radialement interne de N1 enroulements. La tringle (52) pour pneumatique comprend un enroulement (E3,1, E4,1) de prolongement axial de la couche radialement interne (C'inf). La tringle (52) pour pneumatique comprend une couche additionnelle (Ca3) de N2 d'enroulements formant la couche radialement externe de la tringle (52) pour pneumatique(10). |
