Non-pneumatic tire based on triangular chiral negative Poisson's ratio structure

The utility model discloses a non-pneumatic tire based on a triangular chiral negative Poisson's ratio structure. The non-pneumatic tire comprises an outer tire surface, a triangular chiral negative Poisson's ratio support body and a rim, the triangular chiral negative Poisson's ratio supporting body is arranged on the outer side of the rim, and the outer tire face is arranged on the outer side of the triangular chiral negative Poisson's ratio supporting body. After the triangular chiral negative Poisson's ratio supporting body is subjected to a vertical load, the flexible beam stretches due to the negative Poisson's ratio effect, so that the effects of bearing, damping and the like are achieved, and the smoothness of vehicle driving is facilitated. Particularly, the triangular chiral negative Poisson's ratio supporting body is uniform in deformation and large in lateral rigidity, and compared with a common non-pneumatic tire, the driving comfort is remarkably improved.
