The invention relates to a two-unit centrosymmetric structure spoke for a non-pneumatic tire and the tire. The spoke comprises a glass fiber reinforced structure, and a first supporting angle structure, a first argument unit, a second argument unit and a second supporting angle structure which are sequentially connected through the glass fiber reinforced structure; the first supporting angle structure and the second supporting angle structure are symmetrically distributed relative to the center of the first center point, and the first argument unit and the second argument unit are symmetrically distributed relative to the center of the second center point. According to the spoke, the two supporting angle structures are distributed in the central symmetry mode, and the two spoke angle units are distributed in the central symmetry mode, so that the spoke is coupled in the mode that the two units are distributed in the central symmetry mode to achieve the bearing effect, and the sum torque of all internal force on the bonding fixing face is zero during vertical compression; the non-uniform stress distribution of the bonding surface is avoided, the one-way tearing force is greatly reduced, the fatigue strength of the bonding surface is enhanced, and meanwhile, the bending resistance and the stability of the spoke are enhanced.

    本发明涉及一种用于非充气轮胎的二单元中心对称结构轮辐及轮胎,轮辐包括玻纤增强结构以及通过所述玻纤增强结构依次连接的第一支角结构、第一辐角单元、第二辐角单元以及第二支角结构;所述第一支角结构和第二支角结构相对于第一中心点中心对称分布,所述第一辐角单元、第二辐角单元对于第二中心点中心对称分布。本发明的轮辐通过将两个支角结构设置为中心对称分布,将两个辐角单元设置为中心对称分布,从而使得该轮辐实现以二单元中心对称的排布形式耦合达到承载效果,在竖向压缩时各内力在粘接固定面的和力矩为零,避免了胶接面应力分布不均匀、大幅度减小了单向撕拉力,增强了粘接面的疲劳强度,同时增强了轮辐的抗弯扭能力和稳定性。
