摘要:
A pneumatic tire having an equatorial plane and a maximum section width is provided. The tire includes a tread portion having outer tread edges that define a tread arc therebetween, a pair of sidewall portions, a pair of bead portions each of which has a bead core, at least one carcass ply extending circumferentially about the tire from one bead portion to the other and wound outwardly about the bead cores to form a pair of turn-up portions that each terminate at a turn-up, and at least one belt provided between the tread portion and the at least one carcass ply. When the tire is inflated to its specified inflated pressure, the tread portion has a profile that includes a central arc, a pair of intermediate arcs each of which intersects opposite edges of the central arc at a first intersection point, and a pair of outer arcs each of which intersects a respective intermediate arc at a second intersection point. The arc length measured from the equatorial plane of the tire to at least one of the first intersection points is between about 20% and about 60% of one half of the tread arc of the tire, while the arc length measured from the equatorial plane of the tire to at least one of the second intersection points is between about 40% and about 80% of one half of the tread arc of the tire.
摘要(中):
提供具有赤道面和最大截面宽度的充气轮胎。 轮胎包括胎面部分,胎面部分具有限定其间的胎面弧的外胎面边缘,一对侧壁部分,一对胎圈部分,每个胎圈部分具有胎圈芯,至少一个胎体帘布层,其围绕轮胎从一个胎圈部分 并且围绕胎圈芯向外缠绕,以形成一对折叠部分,每个折叠部分以折叠方式终止,以及设置在胎面部分和至少一个胎体帘布层之间的至少一个带。 当轮胎充气到其指定的膨胀压力时,胎面部分具有包括中心弧的轮廓,一对中间弧,每个中间弧在第一交点处与中心弧的相对边缘相交,并且一对外弧 每个在第二交点处与相应的中间弧相交。 从轮胎的赤道平面到至少一个第一交点测量的弧长在轮胎的胎面弧的一半的约20%至约60%之间,而从赤道平面测量的弧长 轮胎至少至少一个第二交点位于轮胎胎面弧的一半的大约40%至大约80%之间。
