The wheel comprises a rim and an outer tire, and further comprises a plurality of air bags which are fixedly installed in a tire cavity along the circumference of the inner side face of the rim, and the air bags form an annular body capable of expanding or contracting in the radial direction; any air bag is internally provided with an independent first inflation cavity, and the annular body has a pre-inflation state and an expansion state. In the pre-inflation state, a gap is formed between the peripheral surface of the annular body and the inner wall surface of the outer tire, so that a second inflation cavity is defined between the inner wall surface of the outer tire and the annular body, and the sum of the air pressure of all the first inflation cavities is consistent with the air pressure of the second inflation cavity; and in the expansion state, the air pressure of the second inflation cavity is reduced, and all the air bags expand in the radial direction till the outer circumferential face of the annular body is attached to the inner wall face of the outer tire so as to fill the second inflation cavity. After the outer tire is punctured or the tire is leaked by shooting, enough air pressure is still provided for supporting the weight of the vehicle to continue running, the running performance is not reduced, and traffic accidents caused by the punctured tire are effectively avoided.

    本发明公开一种内嵌多气囊式爆胎续行车轮及车辆,车轮包括轮辋和外胎,还包括沿轮辋的内侧面一周安装固定在轮胎腔内的多个气囊,多个气囊形成一个可径向扩张或收缩的环形体,任一气囊内具有一个独立的第一充气腔且环形体具有预充状态和扩充状态;在预充状态时,环形体的外周面与外胎的内壁面之间具有间隔,以使外胎的内壁面与环形体之间限定出第二充气腔,所有第一充气腔的气压之和与第二充气腔的气压一致;在扩充状态时,第二充气腔的气压减小,所有气囊沿径向扩张至环形体的外周面与外胎的内壁面贴合以填充第二充气腔。在外胎爆胎或遭遇枪击泄气后仍有足够气压支撑车辆重量继续行驶,且行驶性能不降低,有效避免由爆胎引起的交通事故。
