    揭晓车辆抖动的原因
    2021-10-27 15:05:19

    加速时发生抖动的原因

    Causes of jitter during acceleration

    汽车加速抖动会造成车辆前头发生左右方向上的摆动,所以,在加速时发生抖动首先要检查左右半轴是否弯曲,拆检左右内球笼内壁有无磨损并产生凹坑,大多数是由内球笼损坏引起的。

    The acceleration jitter of the vehicle will cause the front of the vehicle to swing in the left and right directions. Therefore, in case of jitter during acceleration, first check whether the left and right half shafts are bent, dismantle and check whether the inner walls of the left and right inner cages are worn and have pits, most of which are caused by the damage of the inner cages.

    冷启动时发生抖动的原因

    Causes of jitter during cold start

    一般天气较冷,冷车时没怠速,震动是正常的。等水温上来后,恢复到正常转速后,如果抖动比较严重,建议看看是否是节气门脏了,应对油路、节气门、空滤等进行保养和清洗。

    The weather is generally cold. The car doesn't idle when it's cold. The vibration is normal. After the water temperature rises and returns to the normal speed, if the jitter is serious, it is recommended to see if the throttle is dirty, and the oil circuit, throttle and air filter should be maintained and cleaned.

    换挡时发生抖动的原因

    Causes of jitter during gear shifting

    东莞奔驰配件厂表示,换挡时发生抖动,除了油离配合的问题,还有可能是汽车本身出了问题,离合器片、压盘、导向轴承或一轴轴承老化等,所以要检查下是不是这些方面出了问题。如果真是,还可能会加剧传动机构零配件的磨损,缩短其使用寿命,增加油耗等。

    Dongguan Benz parts factory said that in addition to the problem of oil separation coordination, there may be a problem with the car itself, such as the aging of clutch plate, pressure plate, guide bearing or one shaft bearing, so we should check whether there are problems in these aspects. If it is true, it may also aggravate the wear of transmission mechanism parts, shorten their service life and increase fuel consumption.

    怠速时车身抖动的原因

    Causes of body shaking at idle speed

    、发动机积炭严重。车子在行驶一段公里数后,节气门因为过脏会导致关闭不严或怠电动机卡滞,造成发动机怠速过高,在此过程中产生的积炭导致车辆抖动,特别是在启动车辆时,发动机会比正常情况抖动得更厉害一些,要及时清理积碳。

    . the engine has serious carbon deposition. After the car has been driven for a period of kilometers, the throttle valve will not be closed tightly or the idle motor will be stuck because it is too dirty, resulting in too high idle speed of the engine. The carbon deposit generated in this process will cause the vehicle to shake. Especially when starting the vehicle, the engine will shake more severely than normal. The carbon deposit should be cleaned up in time.

    、点火系统问题。在冷车启动时,发动机需要较浓的混合气,混合气就需要较高的点火能量,如果火花塞的间隙太大,点火线圈、高压线圈老化都能导致点火能量下降,使车身发抖。应检查火花塞和分缸线,如不符合需进行调整或更换。

    . ignition system problems. During cold start, the engine needs thicker mixture, and the mixture needs higher ignition energy. If the gap of spark plug is too large, the aging of ignition coil and high-voltage coil can lead to the decrease of ignition energy and make the body tremble. Check the spark plug and cylinder dividing line, and adjust or replace it if it does not meet the requirements.

    、油压不稳。油泵供油压力不正常或进气压力传感器数值错误,都会引发车身抖动。车主要记得检查油压,必要时更换部件。

    . unstable oil pressure. Abnormal fuel supply pressure of oil pump or wrong value of intake pressure sensor will cause body shaking. Remember to check the oil pressure and replace the parts if necessary.

    、避震系统。引擎脚其实是发动机的避震系统,如果引擎脚出现问题,这些震动就会传到方向盘、驾驶室内,造成怠速时发生抖动。

    . shock absorber system. The engine foot is actually the shock absorber system of the engine. If there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, resulting in jitter at idle speed.
