The invention relates to a tyre insert (1) for a vehicle wheel (2), comprising an annular element (10) integrally made of a polymer material. The tyre insert (1) is characterized in that the annular element (10) comprises a base portion (11) adapted to be accommodated in a rim seat (51) of a wheel rim (5) and an enlarged portion (12) having a larger cross-section than the base portion (11). In particular, when the tire is inflated to a predetermined standard working pressure of the tire, the enlarged portion (12) is shaped to have a shape and dimensions that are always spaced from the inside (41) of the tire. On the other hand, when the tire is deflated, the enlarged portion (12) is in contact with the tire to support the tire when the wheel is in operation. The invention also relates to a vehicle wheel (2) comprising a tyre (4), a rim (5) to which the tyre (4) is mounted, and a tyre insert (1).

    本发明涉及一种用于车辆车轮(2)的轮胎插入件(1),该轮胎插入件包括由聚合物材料一体制成的环形元件(10)。轮胎插入件(1)的特征在于,所述环形元件(10)包括适于容纳在车轮轮辋(5)的轮辋座(51)中的基部部分(11)和截面大于基部部分(11)的扩大部分(12)。特别地,当轮胎充气至轮胎的预定标准工作压力时,扩大部分(12)成形为具有总是与轮胎内侧(41)间隔开的形状和尺寸。另一方面,当轮胎放气时,扩大部分(12)在车轮运行时与轮胎接触以支撑该轮胎。本发明还涉及一种车辆车轮(2),其包括轮胎(4)、轮辋(5)和轮胎插入件(1),所述轮胎(4)安装到所述轮辋上。
