The invention discloses a non-pneumatic hollow tire with a reuleaux triangular structure, and belongs to the technical field of non-pneumatic tires. According to the inflation-free hollow tire with the reuleaux triangular structure, a tire belly groove is formed in the tire belly of a tire blank strip extruded by a screw extruder in the circumferential direction of the tire belly, the tire belly groove is formed along the inner side face of the tire belly in a communicating mode, and a communicating inner cavity supporting part is formed in the tire blank strip along the tire belly groove; theinner cavity supporting part is an inner cavity I with the longitudinal section being in a reuleaux triangle shape, the edges of the inner cavity I of the reuleaux triangle are arranged to be in a corrugated shape, so that an inner cavity II is formed, and the stress area of an inner cavity of the tire is increased. Reuleaux triangular holes I are formed in the tire side portion in the circumferential direction of the tire side portion at equal intervals, reuleaux triangular holes II are formed between the adjacent reuleaux triangular holes I in pairs, and therefore riding comfort and stability are both considered.
本发明公开了一种具有莱洛三角形结构的免充气空心轮胎,属于免充气轮胎技术领域。本发明的一种具有莱洛三角形结构的免充气空心轮胎,经过螺杆挤出机挤出的轮胎胚条的胎腹上沿其周向开设有胎腹凹槽,所述胎腹凹槽联通式沿着胎腹内侧面设置,所述轮胎胚条内部沿着所述胎腹凹槽开设有联通的内腔支撑部,所述内腔支撑部为纵截面形状为莱洛三角形的内腔I,所述莱洛三角形的内腔I的边部均设置为波纹型,从而形成内腔II,从而增大轮胎内腔的受力面积;所述胎侧部沿其周向等间距设置有莱洛三角形孔洞I,相邻所述莱洛三角形孔洞I之间成对设置有莱洛三角形孔洞II,进而兼顾骑行的舒适性和稳定性。
