開車時車身抖動，是很多人都會碰到的問題；尤其是使用年限較長的車子，更容易出現(xiàn)這種情況。實際上，車身抖動并不是平白無故產(chǎn)生的，它是一種信號，是來告訴車主，汽車要做檢查了。下面就和
濟南沃爾沃汽車專修人員一起來看看，汽車發(fā)生抖動，到底是哪些地方出現(xiàn)了問題。
The shaking of the car body during driving is a problem that many people encounter; Especially for cars with longer service life, this situation is more likely to occur. In fact, the shaking of the car body is not caused for no reason, it is a signal to inform the owner that the car needs to be inspected. Let's take a look with the repair personnel of Jinan Volvo Cars to see where the car shakes and where the problem is.
一、怠速時車身抖動
1、 Body shaking at idle speed
如果汽車在怠速時，車身抖動，可能是下面這些地方出現(xiàn)了問題。
If the car's body shakes while idling, there may be problems in the following areas.
發(fā)動機積碳較多；節(jié)氣門太臟或噴油嘴的積碳過多，是汽車發(fā)生抖動可能的原因。在發(fā)動汽車時，在積碳上面的燃油會被發(fā)動機吸進汽缸之中燃燒，由于發(fā)動機的可燃混合氣體量一會兒高一會兒低，所以冷啟動時就會出現(xiàn)車身抖動的情況。通常只要按時清潔節(jié)氣門等油路的話，那不會出現(xiàn)這種問題了。
The engine accumulates a lot of carbon; Dirty throttle or excessive carbon accumulation in the fuel injector are possible reasons for car shaking. When starting a car, the fuel on the carbon deposits will be sucked into the cylinder by the engine for combustion. Due to the varying levels of combustible gas mixture in the engine, there may be shaking of the body during cold start. Usually, as long as the throttle valve and other oil circuits are cleaned on time, this problem will not occur.
點火系統(tǒng)故障：這也是怠速時車身抖動的重要原因。如果火花塞、高壓導線、點火線圈出現(xiàn)問題的話，那啟動車子車身也會抖動。這時你可以檢查一下火花塞的積碳是不是太多了，必要時也可以換個新的火花塞。
Ignition system malfunction: This is also an important reason for body shaking during idle speed. If there is a problem with the spark plug, high-voltage wire, or ignition coil, the car body will also shake when starting. At this point, you can check if there is too much carbon accumulation in the spark plug, and if necessary, you can also replace it with a new spark plug.
油壓不穩(wěn)；如果油泵供油壓力異常后進氣壓力傳感器數(shù)值不準確，那也是會發(fā)生抖動的。此時可以查看一下油壓，需要更換的話，就要及時更換。
Unstable oil pressure; If the oil pump supply pressure is abnormal and the intake pressure sensor value is not accurate, it will also cause shaking. At this point, you can check the oil pressure and replace it in a timely manner if necessary.
二、行駛過程中抖動
2、 Shake during driving
輪胎問題
Tire issues
（1）輪圈失圓；通常如果輪胎受到強烈的撞擊，則會導致輪圈失圓。尤其是一些較為扁平的輪胎更容易出現(xiàn)這種問題。輪圈要是失圓，那要想恢復成原狀基本是不太可能，為了自己的安全，還是要重新?lián)Q個輪轂比較好。
(1) The wheel rim is out of circle; Usually, if a tire is strongly impacted, it can cause the wheels to become out of circle. Especially some flat tires are more prone to this problem. If the wheel rim is out of round, it is almost impossible to restore it to its original state. For personal safety, it is better to replace the wheel hub.
（2）輪胎失衡；有些車主在更換新的輪胎時，沒有做輪胎動平衡的習慣，所以汽車在高速運轉(zhuǎn)時，就會出現(xiàn)方向盤發(fā)抖的情況。通常只要到去做個輪胎動平衡就可以了。
(2) Tire imbalance; Some car owners do not have the habit of doing tire dynamic balancing when replacing new tires, so the steering wheel may shake when the car is running at high speed. Usually, just go and do a tire dynamic balance.
（3）輪胎變形；你用手撫摸一圈輪胎胎紋的地方，要是感覺到胎紋呈鋸齒狀，或某條輪胎有個很突出的凸起，那輪胎就是變形了。一般輪胎被尖物扎到，也會出現(xiàn)異響和抖動的情況。
(3) Tire deformation; If you touch the tread area of a tire with your hand and feel that the tread is serrated, or if a tire has a prominent protrusion, then the tire is deformed. Generally, if a tire is punctured by a pointed object, abnormal noise and shaking may also occur.
（4）方向機橫拉桿球頭磨損過度；方向機橫拉桿球頭是活動的，所以難免會出現(xiàn)磨損的情況；不過要是磨損過度的話，那在高速行駛的情況下，轉(zhuǎn)向會不準確，而且輪胎也會抖動起來。
(4) Excessive wear of the steering wheel tie rod ball joint; The ball joint of the steering wheel tie rod is movable, so it is inevitable to experience wear and tear; However, if there is excessive wear and tear, the steering will be inaccurate and the tires will also shake when driving at high speeds.
（5）方向機固定橡膠襯套磨損；通常這種問題基本是不會發(fā)生的，但為了以防萬一，檢查一下還是比較好。這種問題是很容易發(fā)現(xiàn)的，只要你稍微觀察一下就好了。如果方向機固定橡膠襯套有磨損，那在轉(zhuǎn)動方向盤時，方向盤會有抖動的情況。
(5) The fixed rubber bushing of the steering gear is worn; Usually, this kind of problem doesn't happen, but it's better to check it out just in case. This type of problem is easy to detect, as long as you observe it a little. If the fixed rubber bushing of the steering wheel is worn, there will be shaking of the steering wheel when turning it.
傳動軸變形
Transmission shaft deformation
如果車輛出現(xiàn)碰撞，或剮蹭到堅硬的物質(zhì)時，比如馬路牙子、石頭等，那傳動軸螺絲可能會有松動甚至是脫落。如果傳動軸發(fā)生問題，那汽車在加速的時候，抖動的感覺則會更加明顯。
If the vehicle collides or rubs against hard materials such as road teeth, stones, etc., the transmission shaft screws may become loose or even fall off. If there is a problem with the transmission shaft, the feeling of shaking will be more pronounced when the car accelerates.
That's all for explaining the reasons for body shaking during idling and driving. I hope it can be helpful to you. For more information, please visit our website http://www.zhongzaojixie.com consulting service
