自動變速箱維修不能避免拆卸和組裝變速箱。自動變速器的核心是實現(xiàn)自動換擋，所謂自動換擋，是指駕駛員在汽車行駛時根據(jù)行駛過程的需要操縱油門踏板（加速踏板），自動變速器可以根據(jù)發(fā)動機(jī)負(fù)荷和汽車的檔位自動換擋，運行條件。變速箱的保養(yǎng)開始，空轉(zhuǎn)停止，低速或高速行駛，加速，減速，爬升和倒車等，這需要在很大范圍內(nèi)改變汽車的驅(qū)動力和速度，并且目前已廣泛使用 活塞發(fā)動機(jī)輸出扭矩和變速范圍很小。為了適應(yīng)頻繁變化的駕駛條件并使發(fā)動機(jī)在有利的工作條件（更高的功率和更低的燃油消耗）下工作，在變速器系統(tǒng)中安裝了一個變速器。在自動變速器維護(hù)的情況下，次要問題并不表示在嚴(yán)重?fù)p壞自動變速器的情況下，為了從根本上解決問題，需要拆卸和修理自動變速器。當(dāng)然，有時還需要消除一些小問題以進(jìn)行檢查和維護(hù)。因此，變速箱的拆卸和組裝至關(guān)重要。如果不注意，在拆卸過程中可能會損壞變速箱。這樣，變速箱拆卸和組裝的整個過程總結(jié)如下：

Automatic transmission maintenance cannot avoid disassembling and assembling the transmission. The core of an automatic transmission is to achieve automatic shifting. The so-called automatic shifting refers to the driver manipulating the accelerator pedal (accelerator pedal) according to the needs of the driving process while the car is in motion. The automatic transmission can automatically shift gears according to the engine load and the gear position of the car, depending on the operating conditions. The maintenance of the gearbox begins, including idle stop, low-speed or high-speed driving, acceleration, deceleration, climbing, and reversing, which require a wide range of changes in the driving force and speed of the car. Currently, piston engines are widely used with small output torque and transmission range. In order to adapt to frequently changing driving conditions and operate the engine under favorable working conditions (higher power and lower fuel consumption), a transmission is installed in the transmission system. In the case of automatic transmission maintenance, minor issues do not necessarily mean that in order to fundamentally solve the problem of severe damage to the automatic transmission, it is necessary to disassemble and repair the automatic transmission. Of course, sometimes it is necessary to eliminate some minor issues for inspection and maintenance. Therefore, the disassembly and assembly of the gearbox are crucial. If not careful, the gearbox may be damaged during the disassembly process. In this way, the entire process of disassembling and assembling the gearbox is summarized as follows:

自動變速箱維修

Automatic transmission maintenance

1.各種準(zhǔn)備拆卸過程所需的工具小盒零件，然后在干凈平坦的工作臺上拆卸變速箱。

1. Prepare various tools and small box parts required for the disassembly process, and then disassemble the gearbox on a clean and flat workbench.

2.拆卸應(yīng)從前油泵開始，從前到后，從外到內(nèi)開始，并隨時進(jìn)行記錄。

2. Disassembly should start from the front oil pump, from front to back, and from outside to inside, and be recorded at any time.

3.大多數(shù)自動變速箱均由鋁合金制成。拆卸時，禁止使用撬棍和鐵工具直接撞擊。

Most automatic transmissions are made of aluminum alloy. When disassembling, it is forbidden to use pry bars and iron tools to directly impact.

4.拆卸液壓控制閥體時要小心。分離上閥體和下閥體時，請防止球和止動環(huán)掉落在地面上，并準(zhǔn)確記住各部分的正確位置。

4. Be careful when disassembling the hydraulic control valve body. When separating the upper and lower valve bodies, please prevent the ball and stop ring from falling onto the ground and accurately remember the correct positions of each part.

5.拆卸單向離合器時，建議注意正確的安裝方向。 安裝時，不得反轉(zhuǎn)。

When disassembling the one-way clutch, it is necessary to pay attention to the correct installation direction. During installation, do not reverse.

6.拆卸零件后，用煤油清洗零件，并用空氣壓縮機(jī)或其他低壓壓縮空氣設(shè)備干燥。請勿使用棉紗或其他容易去除纖維的擦拭閥零件。

After disassembling the parts, clean them with kerosene and dry them with an air compressor or other low-pressure compressed air equipment. Do not use cotton yarn or other easily removable fiber wiping valve parts.

7.原則上，拆卸后應(yīng)更換底板上的O形圈等易碎部件，并且不應(yīng)再使用諸如老化，變形和磨損之類的易碎部件。

7. In principle, fragile parts such as O-rings on the bottom plate should be replaced after disassembly, and fragile parts such as aging, deformation, and wear should not be used again.

8.應(yīng)將新的離合器盤和制動盤浸入變速箱油中2小時，直到可以注滿足夠的油為止。

8. The new clutch and brake discs should be immersed in transmission oil for 2 hours until sufficient oil can be filled.

9.組裝閥芯，活塞，密封件等時，應(yīng)涂上變速箱油。

When assembling valve cores, pistons, seals, etc., transmission oil should be applied.

10.組裝時，請嚴(yán)格按照規(guī)定的扭矩擰緊每個組件的螺釘。

10. When assembling, please tighten the screws of each component strictly according to the specified torque.
