Title
(EN) Tyre with improved bead structure
(ZH) 具有改进结构的胎圈的轮胎
Abstract
(EN) The invention concerns a tyre (1) with radial carcass reinforcement (13) comprising, viewed in meridian cross-section, two beads (12) with generatrices sloping outwards, the turn-up (130) of said reinforcement (13) being formed by the lateral (30) and radially internal (32) sides of a profiled section (3) of rubber mixture with high Shore hardness in the form of a wedge, and having located axially outside a straight line P2 perpendicular to the axis of rotation and passing through the centre of gravity of the anchoring element (14) and axially inside and radially outside the straight line P1 passing through said centre of gravity and forming with the axis of rotation an angle ranging between 30 degrees and 60 degrees, at least one of the profiled sections (6, 7) of rubber mixtures, between the carcass reinforcement (13) and its turn-up (130) and radially above the annular element (14) and the wedge-shaped profiled section (3), having a Shore hardness at least equal to the hardness of the rubber mixture forming said profiled section (3), and the ratio e1/e2, of the thickness e1 between the carcass reinforcement turn-up (130) and the annular anchoring element (14) over the thickness e2 between the carcass reinforcement turn-up (130) and the bead outer wall, measured on the straight line P1 verifies the relationship 0.05 <= e1/e2 <= 1.0.
(ZH)

一种具有径向胎体增强件(13)的轮胎(1)。当在子午线截面看时,该轮胎包括二个胎圈(12),其母线向外倾斜。所述增强件(13)的向上翻转(130)由楔形成形件(3)的侧边(30)和径向内边(32)形成。所述成形件(3)由肖氏A硬度高的材料制成。并且其末端第一,位于与回转轴线垂直和通过环形固定件(14)的重心的直线P2的轴向外侧,第二,位于通过所述重心和与回转轴线形成30°-60°的角度的直线P1的径向外侧。在胎体增强件(13)及其向上翻转(130)之间,和在环形件(14)与楔形成形件(3)的径向上面的橡胶混合物制的成形件(6,7)中的至少一个成形件的肖氏A硬度,至少等于构成所述成形件(3)的橡胶混合物的硬度。在直线P1上测量的,胎体增强件向上翻转(130)和环形固定件(14)之间的厚度e1,与胎体增强件向上翻转(130)和胎圈外壁之间的厚度e2之比e1/e2满足下列关系:0.05≤e1/e2≤1.0。
