新型汽车轮胎防爆内胎的研制

针对目前防爆轮胎存在防爆效果不佳、价格昂贵、适用范围小等问题,研制了由弹性环套、压力开关、充气装置、安全锁组成的新型防爆内胎,具有结构简单、成本低、安装便捷、起效迅速等特点。选择某型轿车轮胎作为改造和实验对象,进行了动平衡试验和轮胎抗刺扎试验、轮胎脱圈试验等多项道路试验。试验结果表明,新型防爆内胎轮胎动平衡测试结果良好,在汽车高速行驶中爆胎失压后起效迅速,能有效防止车辆侧滑、跑偏,保障汽车安全行驶或停车,具有较好的应用前景。

The Development of New Type Explosion-proof Inner Tube

In view of the problem of current explosion-proof tire,such as ineffective explosion-proof,expensive,small application range,and etc,a new type explosion-proof inner tube consisting of elastic ring set,pressure switch,inflatable device and safety lock was developed.The new type explosion-proof inner tube has the advantages of simple structure,low cost,convenient assembling and quick effect etc.With a tire of one type sedan as an example for reforming and testing,road test such as dynamic balancing test,puncture resistance test and bead unseating test were carried out,which results show that the new explosion-proof inner tube can effectively prevent vehicles from sideslipping and running deviation with its better dynamic balance and rapid effect when the tire pressure loss in high-speed because of tire burst,and ensure safe driving or parking,therefore a good application prospect is foreseen.
