我想大多車主都會遇到過車輪異響這個問題，有時候覺得是小問題就沒有太在意，但汽車異響往往反映了汽車的一些故障或者毛病，如果不能及時發(fā)現(xiàn)排除故障擴大會帶來很大的安 全隱患。說到行車危險，除了剎車故障，油門故障。車輪上的故障那是非常危險的。那如何從車輪上的異響，判斷車輪上可能存在的故障和隱患的？
I think most car owners have encountered the problem of abnormal wheel noise. Sometimes they think it's a small problem and they don't pay much attention to it. However, the abnormal car noise often reflects some faults or faults of the car. If it can't be found and eliminated in time, it will bring great potential safety hazard. When it comes to driving danger, in addition to brake failure, throttle failure. The trouble on the wheels is very dangerous. How to judge the possible faults and hidden dangers from the abnormal noise on the wheel?
1、輪胎扎了釘子、碎石
1. The tire was punctured with nails and gravel
其響聲是輪胎轉(zhuǎn)一圈響一下，就像有個東西“啪嗒”“啪嗒”地敲打地面，隨著車速的提高節(jié)奏加 快。若是石塊撬掉就行，若是釘子，在市內(nèi)時如輪胎氣壓還可以，可直接把車開到維修店補胎。
The noise is that the tire makes a circle, just like something "PATA" and "PATA" knocking on the ground. With the increase of the speed, the rhythm speeds up. If it's a stone, just pry it off. If it's a nail, if the tire pressure is OK in the city, you can drive the car directly to the repair shop to repair the tire.
2、金屬摩擦聲——剎車片過薄
2. Metal friction sound: too thin brake pad
汽車的前輪剎車片一般都有電子的裝置，后輪則沒有，但大都有機 械的報 警片。當剎車盤磨太薄時，就會發(fā)出“刺啦”“刺啦”的金屬摩擦聲。不踩剎車時很輕微，踩剎車時聲音會加重，很刺耳。這時您必 須慢行去換剎車片了。
The front wheel brake pad of a car generally has an electronic device, while the rear wheel does not, but most of them have a mechanical alarm pad. When the brake disc is too thin, it will make a metal friction sound of "pricking" and "pricking". When you don't step on the brake, it's very slight. When you step on the brake, the sound will increase and it's very harsh. Now you have to go slowly to change the brake pads.
一般的車輪從輪輞的空隙中就可以觀察剎車片的厚度，當觀察估算厚度小于3毫米時就一定更換了。更換剎車片要到正規(guī)維修廠換，這是行車安 全的關(guān)鍵零部件，不能馬虎。
Generally, the thickness of the brake pad can be observed from the gap of the wheel rim. When the estimated thickness is less than 3mm, it must be replaced. To replace the brake pads, you need to go to a regular repair shop. It's a key part for driving safety, and you can't be careless.
3、胎面不平
3. Uneven tread
這種異響給人的感覺是輪胎好像一直碾壓著什么東西似的“嗝嚕”“嗝嚕””的聲音，并且常伴有方向盤擺震，忽左忽右的現(xiàn)象。出現(xiàn)這些情況更換輪胎（或輪輞），千萬不要帶病行車。
This kind of abnormal noise gives people the feeling that the tire seems to be rolling something all the time, and it is often accompanied by steering wheel shimmy, left and right. In these cases, replace the tire (or rim), do not drive with disease.
4、車輪軸承異響
4. Abnormal noise of wheel bearing
其聲音是一種“嗡嗡”的響聲，隨車速的增高聲音也逐漸變大。懷疑那個軸承響，可以頂起車輪，按下面的圖片說明檢查。如確實是輪胎軸承響，建議盡快到維修廠檢查更換，以免損壞車軸車體。
Its sound is a kind of "buzzing" sound, and the sound gradually increases with the increase of vehicle speed. If you suspect that the bearing is noisy, you can jack up the wheel and check it according to the picture below. If it is the tire bearing, it is recommended to check and replace it at the maintenance plant as soon as possible to avoid damaging the axle body.
5、胎壓過高，太早變大
5. The tire pressure is too high, too early to increase
一般的轎車胎壓空載時前后應(yīng)均為2.4bar左右，滿載時前為2.6bar左右，后為2.7bar左右。每個車也有差異的，具體準確數(shù)值請看自己車的使用說明書。胎壓太高，跑起來不光能聽到胎噪很大，而且感覺好像懸架變硬了，顛地厲害，并且方向變輕發(fā)飄。遇到這種情況把氣放一些，氣壓調(diào)到標準值就行了。對于帶胎壓監(jiān)控的汽車來說，這樣的情況發(fā)生的很少，因為充高了當時就能看出來。
Generally, the tire pressure of a car should be about 2.4 bar before and after no-load, about 2.6 bar before and about 2.7 bar after full load. There are also differences for each car. Please refer to the user manual of your car for the exact value. The tire pressure is too high. You can not only hear the tire noise when you run, but also feel as if the suspension has hardened, bumped heavily, and the direction has become lighter. In this case, let down the gas and adjust the pressure to the standard value. For a car with tire pressure monitoring, such a situation rarely occurs, because it can be seen when the tire is inflated high.
6、螺栓沒擰緊
6. The bolt is not tightened
聲音是車輛一走一停的瞬間有“咣當”“咣當”的聲音，加減速轉(zhuǎn)向也有明顯的響聲。松的很了，還能感到行駛時車身扭擺，難以駕馭。解決的辦法是重新緊固螺栓，但建議盡快去維修廠檢查一下，螺栓或輪輞上的螺栓孔是否損壞，如損壞更換。
The sound is the sound of "bang" and "bang" at the moment when the vehicle stops and goes, and the obvious sound of acceleration and deceleration steering. It's very loose. I can also feel the body twisting when I'm driving. It's hard to control. The solution is to re tighten the bolts, but it is recommended to go to the repair shop as soon as possible to check whether the bolts or the bolt holes on the wheel rim are damaged, and replace them if they are damaged.
