我想大多车主都会遇到过车轮异响这个问题，有时候觉得是小问题就没有太在意，但汽车异响往往反映了汽车的一些故障或者毛病，如果不能及时发现排除故障扩大会带来很大的隐患。说到行车危险，除了刹车故障，油门故障。车轮上的故障那是非常危险的。那如何从车轮上的异响，判断车轮上可能存在的故障和隐患的？
I think most car owners have encountered the problem of abnormal wheel noise. Sometimes they don't care much if they think it's a small problem, but the abnormal noise often reflects some faults or problems of the car. If they can't find and eliminate the faults in time, it will bring great hidden dangers. Speaking of driving danger, in addition to brake failure, accelerator failure. The fault on the wheel is very dangerous. How to judge the possible faults and hidden dangers on the wheel from the abnormal noise on the wheel?
1、轮胎扎了钉子、碎石
1. The tyre was punctured with nails and gravel
其响声是轮胎转一圈响一下，就像有个东西“啪嗒”“啪嗒”地敲打地面，随着车速的提高节奏快。若是石块撬掉就行，若是钉子，在市内时如轮胎气压还可以，可直接把车开到维修店补胎。
The sound is the sound of the tire turning around. It's like something knocking on the ground. With the increase of the speed, the rhythm is fast. 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、金属摩擦声——刹车片过薄
2. Metal friction sound - brake pads too thin
汽车的前轮刹车片一般都有电子的装置，后轮则没有，但大都用机械的报警片。当刹车盘磨太薄时，就会发出“刺啦”“刺啦”的金属摩擦声。不踩刹车时很轻微，踩刹车时声音会加重，很刺耳。这时您需要慢行去换刹车片了。
The front brake pads of cars generally have electronic devices, while the rear wheels do not, but most of them use mechanical alarm pads. When the brake disc is worn too thin, it will make a metal friction sound of "pricking" and "pricking". It's very slight when you don't step on the brake, and the sound will increase when you step on the brake, which is very harsh. At this time, you need to change the brake pads slowly.
一般的车轮从轮辋的空隙中就可以观察刹车片的厚度，当观察估算厚度小于3毫米时就需要更换了。更换刹车片要到正规维修厂换，这是关键零部件，一定不能马虎。
Generally, the thickness of the brake pad can be observed from the gap of the wheel rim. When the observed estimated thickness is less than 3mm, it needs to be replaced. To replace the brake pads, go to a regular repair shop. This is a key part. We must not be careless.
3、胎面不平
3. Uneven tread
这种异响给人的感觉是轮胎好像一直碾压着什么东西似的“嗝噜”“嗝噜””的声音，并且常伴有方向盘摆震，忽左忽右的现象。出现这些情况就要更换轮胎（或轮辋），千万不要带病行车。
This kind of abnormal noise gives the impression that the tire seems to be rolling on something all the time, and it is often accompanied by the phenomenon of steering wheel shaking and turning left and right. In these cases, replace the tire (or rim) and never drive with disease.
4、车轮轴承异响
4. Abnormal noise of wheel bearing
其声音是一种“嗡嗡”的响声，随车速的提高声音也逐渐变大。怀疑那个轴承响，可以顶起车轮，按下面的图片说明检查。如确实是轮胎轴承响，建议尽快到维修厂检查更换，以免损坏车轴车体。
The sound is a kind of "buzzing" sound, which 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 the tire bearing rings, it is recommended to go to the maintenance factory for inspection and replacement as soon as possible to avoid damaging the axle body.
5、胎压过高，太早变大
5. The tire pressure is too high and gets bigger too early
一般的轿车胎压空载时前后应均为2.4bar左右，满载时前为2.6bar左右，后为2.7bar左右。每个车也有差异的，具体准确数值请看自己车的使用说明书。胎压太高，跑起来不光能听到胎噪很大，而且感觉好像悬架变硬了，颠地厉害，并且方向变轻发飘。遇到这种情况把气放一些，气压调到标准值就行了。对于带胎压监控的汽车来说，这样的情况发生的很少，因为充高了当时就能看出来。
Generally, the tire pressure of passenger cars should be about 2.4 bar before and after no-load, about 2.6 bar before and about 2.7 bar after full load. Each car is also different. Please refer to the user manual of your car for specific and accurate values. The tire pressure is too high. When running, you can not only hear a loud tire noise, but also feel as if the suspension has hardened, bumped heavily, and the direction has become light and floating. In this case, release the air and adjust the air pressure to the standard value. For vehicles with tire pressure monitoring, such a situation rarely occurs, because it can be seen at that time after charging.
6、螺栓没拧紧
6. The bolts are not tightened
声音是车辆一走一停的瞬间有“咣当”“咣当”的声音，加减速转向也有明显的响声。松的很了，还能感到行驶时车身扭摆，难以驾驭。解决的办法是重新紧固螺栓，但建议尽快去维修厂检查一下，螺栓或轮辋上的螺栓孔是否损坏，如损坏就应该尽快更换。
The sound is the sound of "bang" and "bang" at the moment when the vehicle moves and stops, and there is also an obvious sound during acceleration, deceleration and steering. It's very loose. I can still feel the body twisting and swinging when driving, which is difficult to control. The solution is to retighten the bolts, but it is recommended to go to the maintenance factory as soon as possible to check whether the bolt holes on the bolts or rims are damaged. If damaged, they should be replaced as soon as possible.
