車異響往往反映了汽車的一些故障或者毛病,如果能及時(shí)發(fā)現(xiàn)排除能避免故障擴(kuò)大,保證行車安全。相反,會(huì)帶來很大的安全隱患。說到行車危險(xiǎn),除了剎車故障,油門故障。車輪上的故障那是非常危險(xiǎn)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?
The abnormal sound of the car often reflects some faults or faults of the car. If it can be found and eliminated in time, it can avoid the expansion of the fault and ensure the driving safety. On the contrary, it will bring great security risks. 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、啪嗒響——輪胎扎了釘子或者碎石
1. Rattling - a nail or gravel in the tire
其響聲是輪胎轉(zhuǎn)一圈響一下,就像有個(gè)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(shí)如輪胎氣壓還可以,可直接把車開到維修店補(bǔ)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、“刺啦”的金屬摩擦聲——剎車片太薄
2. The sound of metal friction: the brake pads are too thin
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(jī)械的報(bào)警片。當(dāng)剎車盤磨太薄時(shí),就會(huì)發(fā)出“刺啦”“刺啦”的金屬摩擦聲。不踩剎車時(shí)很輕微,踩剎車時(shí)聲音會(huì)加重,很刺耳。這時(shí)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.
3、嗝嚕——胎面不平
3. Hiccup - 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)這些情況更好更換輪胎(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, it's better to change the tire (or rim) and never drive with diseases.
4、車輪軸承異響——嗡嗡
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(gè)軸承響,可以頂起車輪,按下面的圖片說明檢查。如確實(shí)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、胎壓過高異響——胎噪變大
5. Abnormal noise caused by high tire pressure
一般的轎車胎壓空載時(shí)前后應(yīng)均為2.4bar左右,滿載時(shí)前為2.6bar左右,后為2.7bar左右。每個(gè)車也有差異的,具體準(zhǔn)確數(shù)值請(qǐng)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。
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.
