The invention relates to the technical field of automobile tires, and discloses a multi-air-chamber automobile safety tire which comprises a hub, a tire body and a separation layer, a cavity is formed in the tire body, the cavity is arranged in the circumferential direction of the tire body in a surrounding mode, the separation layer is arranged in the cavity, the cavity is divided into two independent sub air chambers through the separation layer in the circumferential direction of the tire body, and the two sub air chambers are sequentially arranged in the radial direction of the tire body; the tire body is provided with a grounding wall in contact with the ground, and the two sub air chambers comprise an outer air chamber and an inner air chamber; the outer air chamber comprises a plurality of mutually independent branch air chambers, and the branch air chambers are sequentially arranged in a surrounding mode in the circumferential direction of the tire body; and therefore, when the automobile runs, if the grounding wall is punctured by foreign matters accidentally and one of the branch air chambers leaks air, the air pressure of the whole tire is not influenced and the normal running of the automobile is not influenced because one branch air chamber occupies a very small space volume of the outer air chamber, so that the occurrence rate of traffic accidents is greatly reduced, and the safety is improved.
本发明涉及汽车轮胎的技术领域,公开了多气室汽车安全轮胎,包括轮毂、胎体和分隔层,胎体内具有空腔,空腔沿着胎体的圆周方向环绕布置,分隔层置于空腔内,沿着胎体的圆周方向,分隔层将空腔分成两个相互独立的子气室,两个子气室沿着胎体的径向依序布置;胎体具有与地面接触的接地壁,两个子气室包括外气室和内气室;外气室包括多个相互独立的分气室,沿着胎体的圆周方向,多个分气室依序环绕布置;这样,当汽车在行驶的时候,如果接地壁不小心被异物扎破,导致其中一个分气室漏气,由于一个分气室占据的外气室的空间体积很小,所以并不会因此影响整个轮胎的气压,不影响汽车的正常行驶,极大地降低了交通事故的发生率,提高了安全性。
