A non-pneumatic tire (100) having an annular beam (200) and an annular support (103) comprising a plurality of thermoplastic elastic spokes formed by a thermoplastic injection molding process. When such a non-pneumatic tire is manufactured using a mold, the radial extension of the mold cavity is defined by the inner radial extension of the annular beam (200). An annular beam (200) of the non-pneumatic tire includes a first elastic body and a circumferential reinforcement extending in a circumferential direction. The annular beam (200) is free of the circumferential reinforcement over a width of at least 8 mm at an axial extension comprising the first elastomer. The plurality of thermoplastic elastic spokes are made of a second elastomer and extend radially inward from the annular beam (200). The invention also relates to a process for forming a non-pneumatic tire (100).

    一种非充气轮胎(100),该非充气轮胎具有环形梁(200)和环形支撑件(103),该环形支撑件包括通过热塑性注塑过程而形成的多个热塑性弹性辐条。当使用模具制造这种非充气轮胎时,模具腔的径向延伸区由环形梁(200)的内径向延伸区限定。该非充气轮胎的环形梁(200)包括第一弹性体和在周向上延伸的周向加强件。环形梁(200)在至少8mm的宽度上在轴向延伸区处无该周向加强件,该轴向延伸区包括该第一弹性体。该多个热塑性弹性辐条由第二弹性体制成并从环形梁(200)沿径向向内延伸。本发明还涉及一种用于形成非充气轮胎(100)的过程。
