The utility model discloses a multi tube air release tyre, which comprises a wheel hub and an outer tube. There is an annular gas pipe, a rubber inner tube and a first gas check valve between the wheel hub and the outer tube. The rubber inner tube is symmetrically arranged with respect to the annular gas pipe, and the rubber inner tube is evenly arranged along the circumference of the wheel hub. The rubber inner tube is connected with the annular gas pipe through the first gas check valve, and the annular gas pipe is connected Through the second gas check valve, it is connected with the external environment. The annular gas pipe is a high temperature resistant rubber pipe. The multi tube tire is used for air release and protection. The shape and quantity of the inner tube are changed to achieve the explosion-proof characteristics. The hub and outer tube can still adopt the standardized structure, which has strong interchangeability and low cost compared with the existing air release and protection tire. Through the pre pressure of each inner tube during inflation, it can reach a certain or certain number of tires When the inner tube is damaged, it can still maintain the overall filling and usability of the tire through the filling function of the undamaged inner tube, so that the car can drive more safely.

技术介绍
随着道路交通的迅速发展,特别是高等级公路里程的增加,汽车轮胎高速行驶量及消耗量大幅提高,因轮胎爆裂而导致的交通事故频发,据统计,2002年我国发生道路交通事故77万起,死亡10.9万人,受伤56.2万人,直接经济损失人民币33.2亿元,其中46%的高等级公路交通事故与轮胎有关,而爆胎占轮胎事故总量的70%;目前,国际上主要有法国米其林公司专利技术的PAX系统,其特征在于一方面具有低气压报警功能,另一方面轮胎内拥有柔性支撑环,在发生爆胎时,可凭借柔性支撑环作用行驶一段距离,日本普利斯通轮胎公司专利技术的SSR系统对轮胎侧面进行加固,当发生爆胎时,可靠侧面加固部分继续行驶,德国大陆轮胎公司开发的CSR系统是在普通轮胎中安装一个钢制的支撑环,保证汽车爆胎时用支撑环辅助汽车前进;固特异公司专利技术的改进型EMT系统利用较软的胶料插入件插在胎侧,以保证爆胎情况下正常行驶,而法国哈钦森公司专利技术的Rodgard和CRF泄气保用轮胎则分别采用滚轮-轮轨与支撑环实现爆胎情况下安全行驶;以上各种防爆轮胎技术多采用在轮毂上或胎侧增加柔性或刚性支撑结构,若直接在轮毂上增加支撑结构,则轮胎的易换性将大打折扣,从而大幅增加防爆轮胎成本,若进行胎侧加固,则一方面爆胎时汽车的行驶稳定性将有一定程度影响,另一方面则会因为加固,使得在更换轮胎时,轮外胎与内胎需一同更换,从而增加轮胎成本;由于上述问题的存在,本专利技术人对现有的泄 ...
