自動上料攪拌車的出現和使用，能夠為各類工程施工提供了諸多的便利，這些都是自動上料攪拌車的功勞，在使用的程度上提升了該設備的作業效率。使用人員要想保障自動上料攪拌車的使用性能，其中，一個重要的配件就是變速器換擋機，每一種配件使用時間長了，都會出現一些問題，在它損壞后如何進行維修呢？小編來講解一下。
The appearance and use of the automatic feeding mixer can provide many conveniences for various engineering construction, which are all the contributions of the automatic feeding mixer, and improve the operating efficiency of the equipment to the extent of use. In order to ensure the service performance of the automatic feeding mixer, one of the important parts is the transmission shifter. Every part will have some problems when it is used for a long time. How to repair it after it is damaged? Let's explain.

1、自動上料攪拌車離合器損壞的原因動力換擋變速器離合器接合時，液壓油的壓力克服彈簧力壓緊摩擦片。隨著液壓油壓力的升高，摩擦片與金屬盤接觸并逐漸壓緊，使離合器將飛輪動力平穩地傳遞到變速器輸人軸。每次換擋時，摩擦片都要與鋼片發生摩擦，產生的熱量由冷卻液散發出去。當摩擦片及鋼片變薄時，為了使它們充分接合就需要更多的液壓油，發動機須進一步加速，摩擦片在鋼片上的打滑時間也隨之延長，由此產生的摩擦熱量也會更多，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，變速器就會產生內泄。而內泄又從兩個方面繼續引起熱量的增加：高壓油經損壞的密封處泄漏，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保證接合離合器時所需的壓力，使離合器充分地接合，這也要求發動機繼續加速，使液壓泵產生更大的流量。如此惡性循環，必將導致離合器過熱或燒損，直完全失效。
1. Causes of clutch damage of automatic feeding agitator truck when the clutch of power shift transmission is engaged, the pressure of hydraulic oil overcomes the spring force to compress the friction plate. With the increase of hydraulic oil pressure, the friction plate contacts with the metal plate and is gradually compressed, so that the clutch smoothly transmits the flywheel power to the transmission input shaft. Every time when shifting, the friction plate will rub with the steel plate, and the heat generated will be dissipated by the coolant. 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 have internal leakage. The internal leakage continues to cause the increase of heat from two aspects: the high pressure oil leaks through the damaged seal, making the oil temperature continue to rise; Due to oil leakage, the hydraulic pump must deliver more oil to ensure the pressure required to engage 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 produce greater flow. Such a vicious cycle will inevitably lead to overheating or burning of the clutch until it is completely ineffective.
