The invention discloses a inflation-free tire. The inflation-free tire comprises a hub; an annular belt located on the periphery of the hub; a plurality of spokes, and the plurality of spokes are arranged between the annular belt and the hub in the circumferential direction; wherein each spoke is in a V shape and comprises two inclined plates arranged at an angle and an arc-shaped vertex angle region formed in the connecting position of the two inclined plates. an resistance part used for limiting the deformation of the vertex angle region to reach the deformation corresponding to the yield strength. According to the inflation-free tire, plastic permanent deformation of the spoke can be effectively avoided by additionally arranging the resistance part, so that the service life of the inflation-free tire can be prolonged.

    本发明公开了一种非充气轮胎,包括:轮毂;环状带,位于所述轮毂的外围;轮辐,其包括多个,多个所述轮辐周向布置在所述环状带与所述轮毂之间;每个所述轮辐均呈V形,所述轮辐包括呈角度设置的两个斜板以及形成于两个所述斜板的连接处的弧形状的顶角区域;抗力部件,其用于限制所述顶角区域的变形量达到屈服强度所对应的变形量。本发明通过增设抗力部件能够有效避免轮辐发生塑性的永久性变形,进而能够提高非充气轮胎的使用寿命。
