The invention discloses an inflation-free hollow tire and a preparation method thereof. The inflation-free hollow tire sequentially comprises an inner ring layer, a middle ring layer, a hollow layer and an outer ring layer from inside to outside; the inner ring layer sequentially comprises a bridle layer and a bead layer from inside to outside, and the middle ring layer sequentially comprises a tire shoulder layer and a middle inner ring layer from inside to outside; the outermost side of the outer ring layer is a tread, the tread is in contact with a road surface, the bridle layer is mounted on a rim of a vehicle, the hollowed-out layer is provided with a plurality of groups of damping units in an annular array, and each group of damping units comprises a first damping hole, a second damping hole, a third damping hole and a fourth damping hole; the corners of the first damping hole, the second damping hole, the third damping hole and the fourth damping hole are in arc transition. The hollowed-out tire structure is a reasonable structure obtained by calculation and optimization through a finite element method, the designed through holes are reasonably distributed in the supporting body in the radial direction and the annular direction, the damping effect is achieved, the weight of the tire can be effectively reduced, and heat convection with the outside is improved, heat generated by rubber due to repeated deformation in the running process of the tire is quickly dissipated, the wear resistance of the tire is improved, and the service life of the tire is prolonged.
本发明公开了一种免充气镂空轮胎及其制备方法,从内到外依次为内环层、中环层、镂空层和外环层,其中内环层由内到外依次为束带层和胎唇层,中环层由内到外依次为胎肩层和中间内环层;外环层的最外边为胎面,胎面与路面接触,束带层安装到车辆的轮辋上,镂空层沿环向阵列排布多组减震单元,每组减震单元包括第一减震孔、第二减震孔、第三减震孔和第四减震孔,第一减震孔、第二减震孔、第三减震孔和第四减震孔的边角处圆弧过渡。本发明中的镂空轮胎结构是利用有限元方法进行计算并优化得到的合理结构,设计的通孔在支撑体中沿径向和环向合理分布,不仅起到减震作用,还能有效降低轮胎的重量,并有利于提高与外部的对流换热、快速散失轮胎行驶过程中因反复变形导致橡胶产生的热量,提高轮胎的耐磨性和使用寿命。
