本发明公开一种免充气式轮胎,其包括胎面和内环及多组鼓包,该多组鼓包呈放射状分布于胎面和内环之间,且每组鼓包内部中空,相邻组鼓包之间一体相连形成环形腔体;相邻组鼓包之连接位置形成凹陷部,该凹陷部对应环形腔体内壁形成收紧内檐,每组鼓包内壁顶部轮廓对应形成环形腔体之扩展外檐,每组鼓包之包壁形成一体连接于收紧内檐和扩展外檐之间的弧形延展面;环形腔体之收紧内檐与鼓包外壁顶部之间形成连接于胎面和内环之间的胎壁。因此,通过于胎面和内环之间设置多组鼓包,增加了轮胎胎壁宽度,并形成了多个相互紧密连接且相互有力支撑的弹性承载单元,从而提高了轮胎的整体承载能力、抗冲击性和行驶舒适性。

    A non-pneumatic tire, including a tread (10), an inner ring (20) and a plurality of groups of bulges (30). The plurality of groups of bulges (30) are radially distributed between the tread (10) and the inner ring (20), each group of bulges (30) is hollowed out inside, and adjacent groups of bulges (30) are integrally connected to form an annular cavity (40); a depression (50) is formed at a connection position of the adjacent groups of bulges (30), the depressions (50) form a tightening inner brim (41) corresponding to an inner wall of the annular cavity (40), a top contour of an inner wall of each group of bulges (30) correspondingly forms an expanding outer brim (42) of the annular cavity (40), and a bulge wall of each group of bulges (30) forms an arc-shaped extension surface (43) integrally connected between the tightening inner brim (41) and the expanding outer brim (42); and a tire wall (60) connected between the tread (10) and the inner ring (20) is formed between the tightening inner brims (41) of the annular cavities (40) and the tops of the outer walls of the bulges (30).
