    變速箱有異常響聲是怎么回事?

    發布日期: 2024-03-22 來源: http://www.566605.com/ 點擊: 0

    故障情況:異常響聲在維修行業稱為異響。在汽車運轉過程中,常見自動變速器內有異響聲、汽車行駛中自動變速器有異響,停車掛檔后異響消失。

    Fault situation: Abnormal noise is called abnormal noise in the maintenance industry. During the operation of a car, it is common for abnormal noises to occur inside the automatic transmission. The abnormal noises also occur while the car is in motion, and disappear after parking and shifting gears.

    一般來說,原因如下幾個方面:

    Generally speaking, the reasons are as follows:

    油泵因磨損過甚或自動變速器油面高度過低、過高而產生異響

    The oil pump may produce abnormal noise due to excessive wear or even low or high automatic transmission oil level

    液力變矩器因鎖止離合器、導輪單向超越離合器等損壞而產生異響

    The hydraulic torque converter produces abnormal noise due to damage to the lock up clutch, guide wheel one-way overrunning clutch, etc

    行星齒輪機構異響

    Abnormal noise from planetary gear mechanism

    換檔執行元件異響

    Gear shift actuator abnormal noise

    解決方法:

    Solution:

    檢查自動變速器油油面高度。若太高或太低,應調整至正確高度。

    Check the oil level of the automatic transmission. If it is too high or too low, it should be adjusted to the correct height.

    應舉升器將汽車升起,起動發動機,在空檔、前進檔、倒檔等狀態下檢查自動變速器產生異響的部位和時刻。

    Lift the car with a hoist, start the engine, and check the location and timing of the abnormal noise generated by the automatic transmission in neutral, forward, reverse, and other states.

    若在任何檔位下自動變速器前部始終有連續的異響,通常為油泵或液力變矩器異響,對此,應拆檢自動變速器,檢查油泵有無磨損、液力變矩器內有無大量摩擦粉末。如有異常,應更換油泵或液力變矩器。

    If there is continuous abnormal noise at the front of the automatic transmission in any gear, usually from the oil pump or hydraulic torque converter, the automatic transmission should be disassembled and inspected for wear on the oil pump and for a large amount of friction powder inside the hydraulic torque converter. If there is any abnormality, the oil pump or hydraulic torque converter should be replaced.

    若自動變速器只有在行駛中才有異響,空檔時無異響,則為行星齒輪機構異響。對此,應分解自動變速器,檢查行星齒輪機構各個零件有無磨損痕跡、齒輪有無斷裂,單向超越離合器有無磨損、卡滯,軸承或止推墊片有無損壞。如有異常,應予以更換。

    If the automatic transmission only makes abnormal noises while driving and there is no abnormal noise in neutral, it is a planetary gear mechanism abnormal noise. In this regard, the automatic transmission should be disassembled, and the various parts of the planetary gear mechanism should be checked for signs of wear, whether the gears are broken, whether the one-way overrunning clutch is worn or stuck, and whether the bearings or thrust washers are damaged. If there are any abnormalities, they should be replaced.
