The invention discloses a non-pneumatic tire with a chiral mixed negative Poisson's ratio structure. In order to solve the technical problem, the invention provides the following technical scheme: the radial plate comprises a radial plate inner ring; the tire crown is arranged on the outer side of the radial plate inner ring; the supporting mechanism comprises at least one concave honeycomb chiral structure layer which is arranged between the radial plate inner ring and the tire crown, and the concave honeycomb chiral structure layer is composed of a plurality of combined units; the Poisson ratio of the supporting mechanism is negative through the combination effect of the combination units. The combination unit at least comprises two connecting beams. Compared with the prior art, the novel concave honeycomb chiral structure layer is arranged, so that the maximum stress borne by the tire can be effectively reduced under the condition of the same load, and the problems of fatigue and damage of the material of the tire due to high load are effectively avoided.

    本发明公开了一种手性混杂负泊松比结构的非充气轮胎。为解决上述技术问题,本发明提供如下技术方案:包括,辐板内圈;胎冠,其设于所述辐板内圈的外侧;以及,支撑机构,包括至少一层设于所述辐板内圈和胎冠之间的内凹蜂窝有手性结构层,所述内凹蜂窝有手性结构层由多个组合单元构成;所述组合单元的组合作用使支撑机构的泊松比为负;所述组合单元至少包括两个连接梁。通过设置新型的内凹蜂窝有手性结构层,相对现有技术,其在同等载荷的情况下,能够有效的减少轮胎自身所受的最大应力,从而有效避免轮胎自身材料因为高载荷在此的疲劳和损坏问题。
