The invention belongs to the technical field of tires. Aiming at the problems of poor shock absorption performance and high noise of the existing non-pneumatic tire, the invention provides a bionic non-pneumatic tire which sequentially comprises a tread, a connecting layer, a bionic buffer structure and a mounting body from outside to inside, the bionic buffer structure comprises a Z-shaped buffer plate imitating the hind limb of a feline, a honeycomb-shaped elastic body, a first outer ring and a first inner ring; the area among the Z-shaped buffer plate, the first outer ring and the first inner ring is filled with the honeycomb-shaped elastic body, and holes of the honeycomb-shaped elastic body is gradually enlarged from the first inner ring to the first outer ring. By means of the Z-shaped buffer structure and the rhombic honeycomb structure, the tire can effectively buffer large vibration and small vibration, the wind noise frequency is broken through, the wind noise of the inflation-free tire is reduced, and the problem that permanent deformation occurs due to insufficient strength of a single structure is solved.
本发明属于轮胎技术领域。针对现有的免充气轮胎存在的减震性能差、噪声大的问题,本发明提供一种仿生免充气轮胎,由外到内依次包括胎面、连接层、仿生缓冲结构及安装体,仿生缓冲结构包括仿猫科动物的后肢的Z形缓冲板、蜂窝状弹性体、第一外圈和第一内圈,Z形缓冲板、第一外圈和第一内圈之间的区域填充蜂窝状弹性体,自第一内圈至第一外圈蜂窝状弹性体的孔由小逐渐变大。通过Z形缓冲结构和菱形蜂窝结构,使轮胎既能够对大振动进行有效缓冲,又能够对小振动进行有效缓冲,打破风噪频率降低免充气轮胎风噪,避免单一结构自身由于强度不足导致发生永久形变的问题。
