    • PROBLEM TO BE SOLVED: To provide a tire assembly incorporating an air maintenance feature that maintains air pressure within a tire.SOLUTION: The tire assembly 10 includes a tire 12 having a pneumatic cavity 40, first and second side walls 30 and 32, a sidewall groove, an air passageway 42, and a pressure regulator mounted to an inner surface of the pneumatic cavity. The pressure regulator controls air pressure within the pneumatic cavity. The first and second sidewalls extend respectively from first and second tire bead regions 34 and 36 to a tire tread region 38. The first sidewall has at least one bending region operatively bending when the tire rolls. The sidewall groove is defined by groove side walls positioned within the bending region of the first sidewall. The groove and the air passage way deform segment by segment between a non-deformed state and a deformed-constricted state in response to the bending of the first sidewall bending region while the tire rolls.
    • 要解决的问题:提供一种包含维持轮胎内的空气压力的空气维护特征的轮胎组件。解决方案:轮胎组件10包括具有气动腔40,第一和第二侧壁30和32的轮胎12,侧壁 凹槽,空气通道42和安装到气动腔的内表面的压力调节器。 压力调节器控制气动腔内的气压。 第一和第二侧壁分别从第一和第二轮胎胎圈区域34和36延伸到轮胎胎面区域38.当轮胎滚动时,第一侧壁具有至少一个弯曲区域可操作地弯曲。 侧壁槽由位于第一侧壁的弯曲区域内的槽侧壁限定。 当轮胎滚动时,槽和空气通道在不变形状态和变形收缩状态之间逐段变形,以响应于第一侧壁弯曲区域的弯曲。
