The invention discloses a cavity supporting structure of a non-pneumatic tire and a machining method of the cavity supporting structure, and belongs to the technical field of tires. According to the cavity supporting structure of the non-pneumatic tire and the machining method of the cavity supporting structure, the middle mold core components of different structural shapes are adopted to form thebag cavity structure matched with the middle mold core components, and the groove similar to a vertical thread structure is formed in the inner side face of the bag cavity so that the effects of enhancing a tire framework structure and dispersing stress are achieved; the semispherical structures are arranged at the head of the bag cavity so that the effects of increasing the size of the bag cavity, reducing the weight of the tire body, saving materials, optimizing the buffering effect and improving the riding comfort are achieved.

    本发明公开了一种免充气轮胎的腔体支撑结构及其加工方法,属于轮胎技术领域。本发明的一种免充气轮胎的腔体支撑结构及其加工方法,通过采用不同结构形状的中模模芯构件,以形成与之相适配的囊腔结构,通过在囊腔内侧面开设类似竖螺纹结构的凹槽,以起到增强轮胎骨架结构及分散应力作用;通过在囊腔头部设置若干个半球形结构,以起到增大囊腔体积、减轻胎体重量、节省材料、优化缓冲效果、提升骑行舒适性作用。
