用于减小气动阻力的轮胎胎边部标记
摘要：
用于装备客车的轮胎(1)，所述轮胎包括冠状部(2)，在所述冠状部的外面设置有当轮胎滚动时意于与道路表面接触的胎面，此冠状部(2)通过胎边部(3，3′)侧向地延展，所述胎边部终结于与安装着所述轮胎的边缘部分(J)接触的胎唇(4，4′)中，每个胎边部包括与给所述轮胎充气的气体接触的内壁和与外部空气接触的外壁，所述胎边部中的至少一个胎边部包括多个第一扇形区(311)和第二扇形区(312)，这些第一和第二扇形区被形成在第一胎边部部分(31)的外壁上，所述第一胎边部部分被定位于冠状部(2)与作为当所述轮胎被安装在所述安装边缘上并且被充气到其使用压力时的轴向最外点的那些点(F)之间，所述轮胎的特征在于第一扇形区(311)完全没有凸起标记，即，没有高度大于0.2mm的凸起标记，而第二扇形区(312)被提供有凸起标记(3120)，这些凸起标记具有等于至少0.2mm的高度，并且特征在于没有标记的第一扇形区(311)分别形成≥20°的角度，并且特征还在于所述第一扇形区的角度的和≥120°。
摘要（英）：

A tyre (1) for a passenger vehicle comprises a crown portion (2) externally provided with a tread intended to be in contact with a road surface when the tyre rolls. The crown portion (2) broadwise extends through sidewalls (3, 3'). The sidewalls ends in the beads (4, 4') in contact with a rim (J) on which the tyre is mounted. Each sidewall includes an inner wall in contact with air for tyre inflation and an outer wall in contact with external air. At least one sidewall of the sidewalls includes a plurality of first sectors (311) and seconds sectors (312) formed on the outer wall of a first sidewall portion (31). The first sidewall is partially located between the crown portion (2) and the points (F) axially furthest to the outside when the tyre is mounted on the rim and is inflated to a working pressure. The tyre is characterized by the first sectors (311) are completely without raised markings of a height greater than 0.2 mm, whereas the second sectors (312) are provided with raised markings (3120) having a height at least equal to 0.2 mm, and the first sectors (311) each forms an angle more than 20 degrees, the sum of the angles of said first sectors are more than 120 degrees.
