浅析轮胎应急支撑装置

Analysis of tire emergency support device

车辆现如今已经融入到人们的日常生活之中,无论是轿车、货车还是其他的专用运输车辆,都与我们的生活息息相关。相应的车辆安全装置也随之进入大众的视野,安全带、ABS防抱死系统以及安全气囊是多年来车辆行业关注并普遍应用的三代安全应急装置。但对于爆胎来说,尤其是高速公路上爆胎引发的恶性事故,这三代安全装置基本上心有余而力不足,很难保障爆胎后的车辆人员安全。据统计,中国每年因爆胎事故伤亡超过40000人,高速上更是有50%以上的死亡事故与爆胎有关,您可能会疑惑爆胎为什么有这么大的威慑力,如果把车辆比作人,那轮胎就像咱们跑步中穿的气垫鞋,地面的温度过高,气垫穿的太久磨损痕迹过重,气垫的气压不正常100160,跑步的时候踩到了坚硬的小石子、小铁钉都会导致气垫漏气甚至爆炸,让我们摔上一跤或者吓上一跳,同理,轮胎的胎压过低、温度过高、磨损的过于严重,还有路面上的障碍物也会导致轮胎爆胎,但轮胎爆胎的后果就要严重的多了。轻者需要更换备胎,修补撞损零件,重者可能就是多车撞毁、多人伤亡了。下图就是一辆特种罐车在高速公路上发生爆胎最终导致整个车辆失控、隔离栏撞毁的可怕过程。

vehicles are integrated into people's daily life. Whether it is cars, trucks or other special transportation vehicles, they are closely related to our lives. The corresponding vehicle safety devices have also entered the public's vision. Seat belts, ABS anti-lock systems, and airbags are three generations of safety emergency devices that have been concerned and commonly used by the vehicle industry for many years. However, for flat tires, especially vicious accidents caused by flat tires on highways, these three generations of safety devices are basically exhausted and insufficient, and it is difficult to ensure the safety of vehicle personnel after flat tires. According to statistics, more than 40,000 people are killed or injured in blowout accidents each year in China, and more than 50 % of deaths are related to blowout accidents at high speeds. You may wonder why blowout tires have such a great deterrent power. If you compare vehicles with people, The tires are like the hovershoes we wear when we run. The temperature on the ground is too high, the hoverpads are too long and the wear marks are heavy. The pressure of the hoverers is not normal 100160. When you step on a hard Pebble and a small iron nail when you run, you can cause the hoverpads to leak or even explode. Let us fall or jump. Similarly, the tire pressure of the tire is too low, the temperature is too high, the wear is too serious, and the obstacles on the road can also cause the tire to burst, but the consequences of the tire puncture are much more serious. The light one needs to replace the spare tire and repair the damaged parts. The heavy one may be a multi-car crash and multiple casualties. The following figure shows the terrible process in which a special tanker exploded on the highway and eventually caused the entire vehicle to lose control and the isolation bar to crash.
