自動(dòng)攪拌車(chē)的出現和使用，能夠為各類(lèi)工程施工提供了諸多的便利，這些都是自動(dòng)上料攪拌車(chē)的功勞，那么你知道導致自動(dòng)攪拌車(chē)離合器過(guò)熱或燒損的原因嗎？下面簡(jiǎn)單來(lái)講講。

The appearance and use of the automatic mixer can provide a lot of convenience for various engineering construction, which is the result of the automatic feeding mixer. Do you know the cause of overheating or burning of the clutch of the automatic mixer? Let's talk about it briefly.

動(dòng)力換擋變速器離合器接合時(shí)，液壓油的壓力克服彈簧力壓緊摩擦片，隨著(zhù)液壓油壓力的升高，摩擦片與金屬盤(pán)接觸并逐漸壓緊，使離合器將飛輪動(dòng)力平穩地傳遞到變速器輸人軸，每次換擋時(shí)，摩擦片都要與鋼片發(fā)生摩擦，產(chǎn)生的熱量由冷卻液散發(fā)出去。

When the clutch of the power shift transmission is engaged, the pressure of the hydraulic oil overcomes the spring force to compress the friction plate. With the increase of the hydraulic oil pressure, the friction plate contacts the metal plate and gradually compresses, so that the clutch smoothly transmits the flywheel power to the transmission input shaft. Each shift, the friction plate will rub with the steel plate, and the heat generated will be dissipated by the coolant.

當摩擦片及鋼片變薄時(shí)，為了使它們充分接合就需要更多的液壓油，發(fā)動(dòng)機須進(jìn)一步加速，摩擦片在鋼片上的打滑時(shí)間也隨之延長(cháng)，由此產(chǎn)生的摩擦熱量也會(huì )更多，促使液壓油的溫度增加，當達到足以改變變速器中密封件性能的溫度時(shí)，變速器就會(huì )產(chǎn)生內泄，而內泄又從兩個(gè)方面繼續引起熱量的增加：

When the friction plate and steel plate become thinner, more hydraulic oil is required to make them fully engaged. The engine must further accelerate, and the sliding time of the friction plate on the steel plate will also be extended. The resulting friction heat will also be more, which will increase the temperature of the hydraulic oil. When the temperature is enough to change the performance of the seals in the transmission, the transmission will produce internal leakage, which will continue to cause the increase of heat from two aspects:

高壓油經(jīng)損壞的密封處泄漏，使油溫繼續升高;由于漏油，液壓泵勢必要輸送更多的油液來(lái)保證接合離合器時(shí)所需的壓力，使離合器充分地接合，這也要求發(fā)動(dòng)機繼續加速，使液壓泵產(chǎn)生更大的流量，如此惡性循環(huán)，必將導致離合器過(guò)熱或燒損，直完全失效。

The high pressure oil leaks through the damaged seal, causing the oil temperature to continue to rise; Due to oil leakage, the hydraulic pump must deliver more oil to ensure the pressure required for engaging the clutch, so that the clutch can be fully engaged. This also requires the engine to continue to accelerate, so that the hydraulic pump can generate greater flow. Such a vicious cycle will inevitably lead to overheating or burning of the clutch until it is completely ineffective.
