The invention discloses a non-pneumatic tire with variable cornering stiffness. The non-pneumatic tire comprises a hub, a rim, a plurality of spokes, three tire bodies and three tire treads, wherein aplurality of groups of through holes penetrating through the end surfaces of the two sides of the three tire bodies are uniformly formed in the three tire bodies, and each group of through holes areuniformly distributed in the circumferential direction; the three tire bodies are sequentially arranged in parallel, the inner walls of the tire bodies are fixedly connected with the outer wall of therim, and the outer walls of the tire bodies are fixedly connected with the inner walls of the three tire treads in a one-to-one correspondence mode. The adjacent tire bodies are fixedly connected andare provided with rigid wire meshes; emergency risk avoiding units are arranged in a group of through holes in the outermost sides of the two tire bodies on the outer sides; the emergency risk avoiding unit comprises a sealing cover, a spring, a mass block and a pressure triggering type air bag. When extreme conditions such as out-of-control trend and even rollover occur due to overlarge lateralacceleration degree caused by sharp turning or emergency avoidance of the vehicle, the cornering rigidity of the wheels can be rapidly increased, so that the wheels generate large resilience force inthe corneringdirection and on the road surface, the out-of-control trend of the vehicle is controlled, and the driving safety is guaranteed.
本发明公开了一种侧偏刚度可变的非充气轮胎,包含轮毂、轮辋、若干轮辐、三个胎体和三个胎面;三个胎体上都均匀设有若干组贯穿其两侧端面的通孔,且每组通孔都在周向上均匀分布;三个胎体依次平行设置,内壁均和轮辋的外壁固连,外壁分别和三个胎面的内壁一一对应固连;相邻胎体之间固连且设有刚性铁丝网;位于外侧的两个胎体的最外侧的一组通孔中均设有紧急避险单元;紧急避险单元包含封盖、弹簧、质量块和压力触发式气囊。在车辆因急剧转弯或紧急避让导致侧向加速度过大进而出现失控趋势甚至侧翻等极端情况时,本发明能够快速增大车轮的侧偏刚度,使车轮在侧偏方向和路面产生较大的回弹力,从而控制车辆的失控趋势,保证行车安全。
