1. When the clutch of power shift transmission is engaged, the pressure of hydraulic oil overcomes the force of spring to press the friction plate. With the increase of the hydraulic oil pressure, the friction plate contacts with the metal plate and gradually compresses, which makes the clutch transfer the flywheel power to the transmission shaft smoothly. Every time the gear is shifted, the friction plate will rub with the steel plate, and the heat generated will be sent out by the coolant. In order to increase the temperature of the oil in the transmission disc, more heat will be needed to increase the temperature of the oil in the transmission plate, which will increase the friction time of the hydraulic disc
而内泄又从两个方面持续引发热量的增添：高压油经破坏的密封处泄露，使油温持续降低；因为漏油，液压泵必将要保送更多的油液来保障接合聚散器时所需的压力，使聚散器充实地接合，这也要求策念头持续加快，使液压泵发生更大的流量。如斯恶性轮回，必将致使聚散器过热或烧损，直至完整生效。
And the internal leakage continues to cause heat increase from two aspects: high pressure oil leakage through the damaged seal, so that the oil temperature continues to rise; due to oil leakage, the hydraulic pump is necessary to deliver more oil to ensure the pressure required to engage the clutch, so that the clutch is fully engaged, which also requires the engine to continue to accelerate, so that the hydraulic pump produces greater flow. Such a vicious cycle will lead to overheating or burning of the clutch until complete failure.

聚散器活塞密封性的检测装载机行走有力或油温太高时，就须要判定是聚散器活塞密封不严还油压缺乏引发的，但惯例检测手腕偶然很难判定是哪一个缘由引发毛病，特别是在无能源的环境下，查抄组装好的变速器总成的各密封环就更坚苦了。此时，可接纳气压阀停止测试。
2. When the loader cannot walk or the oil temperature is too high, it is necessary to judge whether the clutch piston seal is not tight or the oil pressure is insufficient. However, it is difficult to determine which cause the fault by conventional detection methods, especially in the case of no dynamic force, it is more difficult to check the seal rings of the assembled transmission assembly. At this time, the pneumatic valve can be used for testing.
起首，将主动上料打金鱼
变速器节制阀拆掉（对组装好的变速器应在装节制阀之前），而后顺次给变速器各油孔通人0.6一0.8MPa的气体，若某一个孔通人气体时，听到"嘭"的一声且无漏气声或漏气声很小入口计量泵，则申明与之对应的聚散器活塞与缸筒间的密封杰出；若听不到活塞压紧磨擦片的声音且漏气声较大，则申明聚散器·活塞与缸筒间的密封生效，应改换密封件。
Firstly, remove the transmission control valve of the automatic charging mixer (before installing the control valve for the assembled transmission), and then fill the oil holes of the transmission with 0.6-0.8 MPa gas. If a hole is filled with gas, and there is no air leakage or the leakage sound is very small, it indicates that the corresponding clutch piston and cylinder barrel are well sealed If the sound of the piston pressing the friction plate is not heard and the air leakage is large, the seal between the clutch, piston and cylinder barrel is invalid, and the seal should be replaced.
