主题：【原创】中奖-补胎 -- 路人
换个新胎,一旦发生事故责任在生产厂家;由auto shop补胎,出了事他们必须承担一定的责任.北美的auto shop一般是一个机械师应付一辆车,也有带徒弟的,总之人手肯定没国内多.
写这贴不光为了提醒自己注意安全,也因为这件小事让我学到一些轮胎的基本常识.事先我对轮胎几乎一无所知,还停留在儿时记忆的水平,即轮胎分为内胎和外胎,只记得二十年前看邻居补自行车轮胎的片段,然后想当然的认为汽车轮胎也相仿.其实传统轮胎是由内胎+外胎构成,新式轮胎都是Tubeless.找了一段英文解说如下:
Traditional designs of pneumatic tires required a separate inner tube which could fail for a number of reasons, such as: incorrect tire fitment, or friction between the tire wall and inner tube generating excess heat causing a blowout.
Tubeless tire technology does away with the need for an inner tube thereby increasing safety.
In a tubeless tire, the tire, which has an inner lining of impermeable halobutyl, and the rim of the wheel form an airtight seal, with the valve being directly mounted on the rim.
If a tubeless tire gets punctured, air escapes only through the hole, leading to a gentle deflation of the tire. Conversely, an inner tube could potentially burst like a balloon, leading to a rapid deflation of the tire which could result in sudden loss of control of the vehicle. A liquid tire sealant can be added to tubeless tires to prevent deflation.
Also people can use the tubeless tire to put on their wheel barrels to improve both the performance and durability of it.
最初的确有自己把胎补好的想法,看完tubeless的介绍后彻底放弃了这个念头.一则是没有相应的工具把胎剥离rim,二则气密性无法保障.说到底,轮胎是个人命关天的因素,马虎不得.
