变速箱作为汽车上的“三大件”之一，其好坏直接关系到车辆的操控性和安全性，一旦出现故障，易引发交通事故。变速箱异响一般分为三种异响，轴承异响、差速器异响、油泵异响。下面济南自动变速箱维修人员就来我们网站咨询吧！

As one of the "three major parts" of the automobile, the quality of the gearbox is directly related to the handling and safety of the vehicle. Once it breaks down, it is easy to cause traffic accidents. The abnormal noise of gearbox is generally divided into three types: bearing abnormal noise, differential abnormal noise and oil pump abnormal noise. Next, Jinan automatic transmission maintenance personnel will come to our website for consultation!

轴承异响，一般轴承的异响同转速关系密切，转速越高越有尖叫声。

Abnormal noise of bearing. Generally, the abnormal noise of bearing is closely related to the rotating speed. The higher the rotating speed, the higher the squeal.

差速器异响，差速器连接的是半轴/车轮，这种异响随着车速的变化而变化，它并不受发动机转速和档位的影响，仅仅受到车速的影响。另外，安装问题也会造成主减速器异响、差速器异响。

The differential makes abnormal noise. The differential is connected to the axle/wheel. This abnormal noise changes with the change of the vehicle speed. It is not affected by the engine speed and gear, but only by the vehicle speed. In addition, installation problems will also cause abnormal noise of the main reducer and differential.

油泵异响随着压力的变化而变化。这时把自动变速箱所在的档位全部挂完，并相应改变其发动机转速，如果异响一直存在的话，可以排除传动机构上的元件产生异响。

The abnormal sound of the oil pump changes with the pressure. At this time, put all the gears of the automatic transmission into gear, and change its engine speed accordingly. If the abnormal noise persists, it can be ruled out that the components on the transmission mechanism produce abnormal noise.

在检查油泵之前，可以通过一些测试来判断，调节主油压，如果异响随着主油压变化而变化，那时说明油泵有故障。油泵的异响也可能是由于油格堵塞造成的，可以用油压表来盘点这种类型的问题，如果是油格堵塞而造成的油泵异响，挡负荷增加引起油压增加时，油压表的指针将会波动很大，起伏不定。

Before checking the oil pump, you can judge and adjust the main oil pressure through some tests. If the abnormal noise changes with the main oil pressure, then the oil pump is faulty. The abnormal noise of the oil pump may also be caused by the clogging of the oil grid. You can use the oil pressure gauge to check this type of problem. If the abnormal noise of the oil pump is caused by the clogging of the oil grid, and the increase of the oil pressure caused by the increase of the block load, the pointer of the oil pressure gauge will fluctuate greatly and fluctuate.

车辆行驶中如果出现无节奏的沉闷响声，且在握住变速杆时，响声消失，则可能是该档齿轮拨叉凹槽磨损或变速杆下端工作面磨损造成的，应将变速箱拆下进行检修或更换。

If there is a dull noise without rhythm during driving and the noise disappears when holding the shift lever, it may be caused by the wear of the shift fork groove of the gear or the wear of the working surface at the lower end of the shift lever. The transmission should be removed for maintenance or replacement.

对于一位经验丰富驾驶员来说，车辆常见的一些故障是必需要了解其原因和维修方法的，因为平时开车，少不了要外出，一旦车辆出现故障，而附近又没有修理厂时，自己能掌握一些修车常识，无疑会减少很多麻烦。同时，还可以及时了解车辆状况，避免发生突发事故。更多相关内容就来我们网站http://www.jnbsx.com咨询吧！

For an experienced driver, it is necessary to understand the causes and maintenance methods of some common faults of the vehicle, because it is necessary to go out when driving normally. Once the vehicle breaks down and there is no repair shop nearby, you can master some common knowledge of vehicle repair, which will undoubtedly reduce a lot of trouble. At the same time, it can also know the vehicle condition in time to avoid accidents. Come to our website for more relevant content http://www.jnbsx.com Ask!
