The invention provides a non-pneumatic tire. The non-pneumatic tire includes an annular inner ring, an annular outer ring, and a support structure extending from the annular inner ring to the annular outer ring. The support structure includes a multi-layer structure. The multilayer structure includes a skim layer, a plurality of cords embedded in the skim layer, and an outer protective layer covering at least a portion of a surface of the skim layer. And the outer protective layer has higher ozone exposure resistance than the skim layer. The present invention also provides a method of manufacturing a non-pneumatic tire, the method comprising forming a multi-layer structure by applying an outer protective layer onto at least a portion of a surface of a skim layer having a plurality of cords embedded in the skim layer.

    本发明提供了一种非充气轮胎,该非充气轮胎包括环形内圈、环形外圈以及从环形内圈延伸到环形外圈的支撑结构。支撑结构包括多层结构。多层结构包括胶清层、嵌入胶清层中的多根帘线和覆盖胶清层的表面的至少一部分的外保护层。外保护层比胶清层具有更强的抗臭氧暴露性。本发明还提供了制造非充气轮胎的方法,该方法包括通过将外保护层施加到胶清层的表面的至少一部分上来形成多层结构,该胶清层具有嵌入该胶清层中的多根帘线。
