變速箱是汽車中進行機械動力轉換的機械或液壓設備。這里，我們把自動變速箱的維修過程分三步：拆卸前、拆卸時、后期解體與裝合。下面濟南自動變速箱維修廠家為您分析：

Gearbox is a mechanical or hydraulic equipment for mechanical power conversion in automobiles. Here, we divide the maintenance process of automatic transmission into three steps: before disassembly, during disassembly, and after disassembly and assembly. Jinan automatic transmission maintenance manufacturer will analyze for you:

自動變速箱拆卸前

Before removal of automatic transmission

在拆卸自動變速箱之前一定要查找庫存是否有對應的自動變速箱型號，在不能保證起碼的易損件和必換件都充沛的情況下，不建議立即拆卸解體。可先放干變速箱機油，卸下優盤，檢車殘油品種的雜質部分，在正常情況下，含有深褐色或褐色粉末為離合器片磨損，亮白色金屬粉末為油泵、單向離合器、齒輪機構磨損，從而進一步判斷車子的故障。

Before disassembling the automatic transmission, it is necessary to check whether there is a corresponding automatic transmission model in the inventory. In the case that the minimum number of vulnerable parts and necessary parts cannot be guaranteed, it is not recommended to disassemble it immediately. The transmission oil can be drained first, and the USB flash disk can be removed to check the impurity part of the residual oil. Under normal conditions, the dark brown or brown powder is the wear of the clutch plate, and the bright white metal powder is the wear of the oil pump, one-way clutch and gear mechanism, so as to further judge the fault of the vehicle.

自動變速箱拆卸時

When removing the automatic transmission

因車身底板形狀個位置的限制，直接從發動機后部拆下變速箱往往顯得空間不夠，可靠的辦法是連同發動機一同從車上吊下。把自動變速箱拉離發動機時，應該沿著軸向拉動，克伴以繞軸線的順和反方向轉動，但不得上下左右擺動，以免損壞自動變速箱輸入軸與液力耦合器或變矩器連接比分的表面狀況與配合。

Due to the limitation of the shape and position of the underbody, it is often not enough space to remove the gearbox directly from the rear of the engine. The reliable way is to lift it together with the engine from the vehicle. When the automatic transmission is pulled away from the engine, it should be pulled along the axial direction, and it should rotate in the clockwise and reverse directions around the axis, but it should not swing up, down, left and right, so as not to damage the surface condition and fit of the automatic transmission input shaft and the hydraulic coupler or the torque converter connection ratio.

后期解體與裝合

Later disassembly and assembly

先準備好工具及盛放各類零件的小盒子，在干凈平整的操作臺上進行解體，從前部油泵開始，從前至后，由外向里逐步進行，并做好記錄。

First prepare tools and small boxes containing various parts, and disassemble them on a clean and flat operating platform. Start from the front oil pump, from front to back, from outside to inside, and make records.

在拆卸的時候，一定要記住不能用撬棍和鐵器直接敲打，因自動變速箱殼體大多數用鋁合金鑄成，在拆卸液控閥體是防止上下閥體分離時滾珠、卡環等掉地，要準確記住正確位置，拆卸單向離合器要注意正確配裝方向，裝合時不能顛倒，零件拆卸后應用汽油洗凈，確保各元件的清潔。

When disassembling, remember not to knock directly with crowbars and irons, because most of the automatic transmission housing is made of aluminum alloy. When disassembling the hydraulic control valve body, it is necessary to prevent the ball, snap ring, etc. from falling off the ground when the upper and lower valve bodies are separated. Remember the correct position accurately. When disassembling the one-way clutch, pay attention to the correct assembly direction, and do not reverse it during assembly. After disassembling the parts, clean them with gasoline to ensure the cleanness of all components.

如更換新離合器片、制動片應在變速箱油中浸泡，待吸足油后才能裝合，另外一定要注意，裝合時嚴格按照規定力矩擰緊螺釘。

If a new clutch disc or brake disc is replaced, it should be soaked in the transmission oil and can be assembled only after sufficient oil is absorbed. In addition, it must be noted that the screws should be tightened strictly according to the specified torque during assembly.
