Non-pneumatic tire outer wheel, non-pneumatic tire and preparation method

The invention discloses a non-pneumatic tire outer wheel, a non-pneumatic tire and a preparation method, and belongs to the technical field of non-pneumatic tires. The non-pneumatic tire outer wheel comprises a metal outer wheel body, a brass layer is arranged on the surface, making contact with a tread, of the metal outer wheel body, and air holes are formed in the metal outer wheel body; and the mass fraction of Cu in the brass layer is 63.5 +/-2.5%. The outer wheel of the non-pneumatic tire is applied to the aspect of the non-pneumatic tire, solves the problem of connection between the metal outer wheel and the tread of the existing non-pneumatic tire, can realize firm connection between the tread and the metal outer wheel, and is particularly suitable for vehicles with higher vehicle speeds. 本发明公开了一种免充气轮胎外轮、免充气轮胎及制备方法，属于免充气轮胎技术领域。该免充气轮胎外轮包括金属外轮，金属外轮与胎面接触的表面设有黄铜层，金属外轮上开设有气孔；黄铜层中Cu的质量分数为63.5±2.5％。本发明应用于免充气轮胎方面，解决现有免充气轮胎存在的金属外轮与胎面的连接问题，本发明的免充气轮胎外轮能够实现胎面与金属外轮的牢固连接，尤其适合较高车速的车辆使用。
