When the screw is tightened, the tire will fly off when the vehicle is running.
The vehicle on the road suddenly flew off the tire, and its impact force hit the passerby more, endangering public safety. Li Yaopei, president of the Hong Kong Automobile Industry Association, estimates that the minibus wheel passes through the tool commonly known as the "wind gun". The force is too large when screwing the screw, and the shock caused by the driving, so that the screw shaft is damaged and the crack is also driving. The more the shock, the more it breaks and eventually breaks and causes the wheels to fly off. He suggested that the authorities should enforce the licensing system and the licensing system for car dealerships to strengthen supervision.
Li Yaopei, President of the Hong Kong Automobile Industry AssociationThere are several reasons for the vehicle to fly off, except that the metal fatigue or unstable installation caused by the aging of the tire screws is also related to the excessive force when using the screws on the tool. Li Yaopei explained that the five screws on the axle connecting the fly-off tires were all broken at the same time. It is estimated that the force during installation of the screws was too large, causing cracks inside the screws.
Experts refer to the five-port screw of the wheel, suspected to be broken due to metal fatigue
Metal silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive for non-ferrous alloys. Metal silicon is produced from quartz and coke smelted in an electric furnace. The content of main component silicon is about 98% (In recent years, 99.99% of Si is contained in metallic silicon), and the remaining impurities are iron and aluminum. , calcium and so on.
