装载机某一档位行走无力或不行走的原因
来源：/ 日期：2022-08-30
在使用装载机施工时，人员须持证上岗，严禁非专门的技术人员操作，在作业时要注意，严格按操作流程来。此外要提前知道一些相关问题，避免意外出现，下面济南装载机租赁厂家为您讲一个问题--装载机某一档位行走无力或不行走，而其余档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?
判断要点：
Judgment points:
不行走或行走缓慢时，主传动轴旋转快速有力，提升发动机转速时，主传动轴转速的提升与前后传动轴明显不成比例。
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.
空档及其余档位变速油压正常，挂该挡后压力明显下降。
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)轴承盖或尼龙环严重磨损。
1) The bearing cover or nylon ring is severely worn.
2)如轴承盖或尼龙环良好或磨损轻微，则确认该档离合器内外封环密封不良。
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:
更换相应损坏零件即轴承盖或尼龙环、内外封封环，重新调整轴套与轴承盖间隙。
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:
某一档位行走无力或不行走，可排除变矩器、行走泵、减压阀等各档公用油路和部件的问题，故障发生的部位只能在变速控制阀之后到该档离合器活塞之间的油路上。
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.
轴承盖、尼龙环、内外封封环等薄弱部件磨损后，供往离合器活塞腔的油液从磨损部位大量泄漏，从而造成油压降低。挂空挡或其余档位由于油液不流经磨损部位，因而油压显示正常。
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.
The reason why the loader is unable to move or does not move at a certain gear and the analysis content have been solved for you. You can use it as reference information. Of course, you can come to the website at any time when you need it Contact us.
