开车时车身抖动，是很多人都会碰到的问题；尤其是使用年限较长的车子，更容易出现这种情况。实际上，车身抖动并不是平白无故产生的，它是一种信号，是来告诉车主，汽车要做检查了。下面就和
济南沃尔沃汽车专修人员一起来看看，汽车发生抖动，到底是哪些地方出现了问题。
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、怠速时车身抖动
1、 Body shaking at idle speed
如果汽车在怠速时，车身抖动，可能是下面这些地方出现了问题。
If the car's body shakes while idling, there may be problems in the following areas.
发动机积碳较多；节气门太脏或喷油嘴的积碳过多，是汽车发生抖动可能的原因。在发动汽车时，在积碳上面的燃油会被发动机吸进汽缸之中燃烧，由于发动机的可燃混合气体量一会儿高一会儿低，所以冷启动时就会出现车身抖动的情况。通常只要按时清洁节气门等油路的话，那不会出现这种问题了。
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.
点火系统故障：这也是怠速时车身抖动的重要原因。如果火花塞、高压导线、点火线圈出现问题的话，那启动车子车身也会抖动。这时你可以检查一下火花塞的积碳是不是太多了，必要时也可以换个新的火花塞。
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.
油压不稳；如果油泵供油压力异常后进气压力传感器数值不准确，那也是会发生抖动的。此时可以查看一下油压，需要更换的话，就要及时更换。
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、行驶过程中抖动
2、 Shake during driving
轮胎问题
Tire issues
（1）轮圈失圆；通常如果轮胎受到强烈的撞击，则会导致轮圈失圆。尤其是一些较为扁平的轮胎更容易出现这种问题。轮圈要是失圆，那要想恢复成原状基本是不太可能，为了自己的，还是要重新换个轮毂比较好。
(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）轮胎失衡；有些车主在更换新的轮胎时，没有做轮胎动平衡的习惯，所以汽车在高速运转时，就会出现方向盘发抖的情况。通常只要到去做个轮胎动平衡就可以了。
(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）轮胎变形；你用手抚摸一圈轮胎胎纹的地方，要是感觉到胎纹呈锯齿状，或某条轮胎有个很突出的凸起，那轮胎就是变形了。一般轮胎被尖物扎到，也会出现异响和抖动的情况。
(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）方向机横拉杆球头磨损过度；方向机横拉杆球头是活动的，所以难免会出现磨损的情况；不过要是磨损过度的话，那在高速行驶的情况下，转向会不准确，而且轮胎也会抖动起来。
(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）方向机固定橡胶衬套磨损；通常这种问题基本是不会发生的，但为了以防万一，检查一下还是比较好。这种问题是很容易发现的，只要你稍微观察一下就好了。如果方向机固定橡胶衬套有磨损，那在转动方向盘时，方向盘会有抖动的情况。
(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.
传动轴变形
Transmission shaft deformation
如果车辆出现碰撞，或剐蹭到坚硬的物质时，比如马路牙子、石头等，那传动轴螺丝可能会有松动甚是脱落。如果传动轴发生问题，那汽车在加速的时候，抖动的感觉则会更加明显。
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.lutongqixiu.com consulting service
