The invention provides a non-pneumatic tire and a wheel, wherein at least two springback grooves are formed in the inner tire surface, and the distance between the bottom walls of the springback grooves and the outer tire surface is controlled to be kept, that is, the springback grooves do not penetrate through the outer tire surface, so that the springback grooves are of blind groove structures,and the structural integrity of the outer tire surface is guaranteed. Meanwhile, a supporting part is formed between every two adjacent springback grooves, and when the tire body is subjected to impact force, the impact force is mainly transmitted to the supporting parts from the outer tire surface; and then the signals are transmitted to the hub through the supporting part. Due to the fact that the springback grooves are formed in the two sides of the supporting part, the elastic function of the tire body structure is effectively improved, before the impact force is completely transmitted tothe hub, the supporting part is pressed to arch towards the interiors of the springback grooves in the two sides to generate elastic deformation, the two sides of the supporting part bear springback internal stress generated by deformation of the structure, and part of the impact force is counteracted; therefore, impact energy acting on the tire body is effectively absorbed, it is guaranteed thatthe non-pneumatic tire has good buffering performance, and the riding or driving comfort of a vehicle is effectively improved.

    本发明涉及一种免充气轮胎及车轮,在内胎面上开设至少两个回弹槽,并控制回弹槽的底壁与外胎面保持间距,即,回弹槽不贯穿外胎面,使得回弹槽为盲槽结构,保证外胎面结构完整。同时,在相邻两个回弹槽之间形成支撑部,当胎体受到冲击力时,冲击力主要由外胎面传递至支撑部上;再由支撑部传递至轮毂上。由于支撑部两侧均设有回弹槽,因此,有效改善胎体结构的弹性功能,在冲击力完全传递至轮毂之前,支撑部受压会向两侧的回弹槽内拱起发生弹性变形,使得支撑部的两侧受到结构本身因变形而产生的回弹内应力,抵消部分冲击力,使得作用在胎体上的冲击能量得到有效吸收,保证免充气轮胎具有良好的缓冲性能,有效提升车辆骑行或者驾驶的舒适度。
