    • The invention is directed to a shoulder construction of the tread area of pneumatic tires which provides increased stability and reduced wear. The shoulder construction comprises a decoupling rib having an outer surface arranged circumferentially about the tire on an outer edge of the tread portion. A shoulder rib, which also has an outer surface, is arranged inwardly of an adjacent the decoupling rib. A groove, which is defined by the inner and outer side faces of the decoupling rib and the shoulder rib, extends from its base radially beneath the outer surface of the decoupling rib first diagonally toward and then away from the central radial axis of the shoulder rib. The groove configures the inner and outer side faces of the decoupling and shoulder ribs in conforming image and forms an unsupported outer surface area on the shoulder rib. This construction, under nominal pressure and load at the foot portion, provides radial stress which is substantially equalized from an outer edge over a major portion of the outer surface of the shoulder rib and provides for a portion of the inner side surface of the decoupling rib and a portion of the outer side surface of the shoulder rib to move into mutual contact providing reduced wear and increased lateral stability of the shoulder rib.
    • 本发明涉及充气轮胎的胎面区域的肩部结构,其提供增加的稳定性和减少的磨损。 肩部结构包括在胎面部分的外边缘上具有围绕轮胎周向布置的外表面的去耦肋。 还具有外表面的肩肋布置在邻近解耦肋的内侧。 由解耦肋和肩肋的内侧面和外侧面限定的凹槽从其底部在解耦肋的外表面径向向下延伸,首先对角地朝向并随后远离肩肋的中心径向轴 。 凹槽构成了去耦合和肩肋的内侧面和外侧面的形状,并在肩肋上形成无支撑的外表面区域。 这种在脚部的公称压力和负载下的结构提供了径向应力,该应力基本上与肩肋的外表面的大部分上的外边缘相等,并且提供了解耦肋的内侧表面的一部分 并且所述肩肋的外侧表面的一部分移动成相互接触,从而降低所述肩肋的磨损和增加的横向稳定性。
