变速箱是汽车中进行机械动力转换的机械或液压设备。这里，我们把自动变速箱的维修过程分三步：拆卸前、拆卸时、后期解体与装合。下面
济南自动变速箱维修厂家为您分析：
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:
自动变速箱拆卸前
Before removal of automatic transmission
在拆卸自动变速箱之前一定要查找库存是否有对应的自动变速箱型号，在不能保证起码的易损件和必换件都充沛的情况下，不建议立即拆卸解体。可先放干变速箱机油，卸下优盘，检车残油品种的杂质部分，在正常情况下，含有深褐色或褐色粉末为离合器片磨损，亮白色金属粉末为油泵、单向离合器、齿轮机构磨损，从而进一步判断车子的故障。
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.
自动变速箱拆卸时
When removing the automatic transmission
因车身底板形状个位置的限制，直接从发动机后部拆下变速箱往往显得空间不够，可靠的办法是连同发动机一同从车上吊下。把自动变速箱拉离发动机时，应该沿着轴向拉动，克伴以绕轴线的顺和反方向转动，但不得上下左右摆动，以免损坏自动变速箱输入轴与液力耦合器或变矩器连接比分的表面状况与配合。
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.
后期解体与装合
Later disassembly and assembly
先准备好工具及盛放各类零件的小盒子，在干净平整的操作台上进行解体，从前部油泵开始，从前后，由外向里逐步进行，并做好记录。
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.
在拆卸的时候，一定要记住不能用撬棍和铁器直接敲打，因自动变速箱壳体大多数用铝合金铸成，在拆卸液控阀体是防止上下阀体分离时滚珠、卡环等掉地，要准确记住正确位置，拆卸单向离合器要注意正确配装方向，装合时不能颠倒，零件拆卸后应用汽油洗净，确保各元件的清洁。
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.
如更换新离合器片、制动片应在变速箱油中浸泡，待吸足油后才能装合，另外一定要注意，装合时严格按照规定力矩拧紧螺钉。
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.
In order to ensure the driving safety of the majority of car owners, you must use the vehicle correctly in normal driving. If there is a problem with the vehicle, you must send it to the company for inspection and repair in time to avoid serious damage!
