裝載機某一檔位行走無力或不行走的原因

在使用裝載機施工時，人員須持證上崗，嚴禁非專門的技術人員操作，在作業時要注意安全，嚴格按操作流程來。此外要提前知道一些相關問題，避免意外出現，下面濟南裝載機租賃廠家為您講一個問題--裝載機某一檔位行走無力或不行走，而其余檔位正常是怎么回事呢？

When using the loader for construction, the personnel must take the post with certificates. It is strictly prohibited for non professional personnel to operate. Pay attention to safety during operation and strictly follow the operation process. In addition, it is necessary to know some relevant problems in advance to avoid accidents. The following is a question for you from Jinan loader rental manufacturer: what is the problem that a certain gear of the loader is unable to move or cannot move, while the other gears are normal?

判斷要點：

Judgment points:

不行走或行走緩慢時，主傳動軸旋轉快速有力，提升發動機轉速時，主傳動軸轉速的提升與前后傳動軸明顯不成比例。

When it is unable to walk or moves slowly, the main drive shaft rotates rapidly and forcefully. When the engine speed is increased, the speed of the main drive shaft is obviously out of proportion with the front and rear drive shafts.

空檔及其余檔位變速油壓正常，掛該擋后壓力明顯下降。

The transmission oil pressure of neutral gear and other gears is normal, and the pressure drops significantly after the gear is engaged.

故障原因：

Fault cause:

1)軸承蓋或尼龍環嚴重磨損。

1) The bearing cover or nylon ring is severely worn.

2)如軸承蓋或尼龍環良好或磨損輕微，則確認該檔離合器內外封環密封不良。

2) If the bearing cover or nylon ring is in good condition or slightly worn, confirm that the inner and outer sealing rings of the clutch are not well sealed.

排除方法：

Exclusion method:

更換相應損壞零件即軸承蓋或尼龍環、內外封封環，重新調整軸套與軸承蓋間隙。

Replace corresponding damaged parts, i.e. bearing cover or nylon ring, inner and outer sealing ring, and readjust the clearance between shaft sleeve and bearing cover.

故障分析：

Fault analysis:

某一檔位行走無力或不行走，可排除變矩器、行走泵、減壓閥等各檔公用油路和部件的問題，故障發生的部位只能在變速控制閥之后到該檔離合器活塞之間的油路上。

If a certain gear is unable to move or cannot move, the problem of common oil paths and components of various gears such as torque converter, travel pump and pressure reducing valve can be eliminated. The fault can only occur in the oil path between the transmission control valve and the clutch piston of the gear.

軸承蓋、尼龍環、內外封封環等薄弱部件磨損后，供往離合器活塞腔的油液從磨損部位大量泄漏，從而造成油壓降低。掛空擋或其余檔位由于油液不流經磨損部位，因而油壓顯示正常。

After the weak parts such as bearing cover, nylon ring and inner and outer seal rings are worn, the oil supplied to the clutch piston cavity leaks from the worn parts in a large amount, thus causing the oil pressure to decrease. In neutral gear or other gears, the oil pressure display is normal because the oil does not flow through the worn parts.
