一、奧迪CVT自動(dòng)變速器故障有些來自輸入軸離合器,CVT自動(dòng)變速箱維修故障這些離合器摩擦片結(jié)合不好的原因。摩擦副組合不好的原因是摩擦片本身的磨損,還受到液壓系統(tǒng)壓力的影響。液壓來自機(jī)油泵,通過閥體調(diào)節(jié)分配給離合器,并由電子控制單元控制。
1、 Some of the faults of Audi CVT automatic transmission come from the input shaft clutch. The maintenance faults of CVT automatic transmission are the reasons for the poor combination of clutch friction plates. The poor combination of friction pairs is due to the wear of the friction plate itself and the pressure of the hydraulic system. The hydraulic pressure comes from the oil pump, is distributed to the clutch through the valve body adjustment, and is controlled by the electronic control unit.
不規(guī)則形狀是閥體,齒輪是油泵。油泵一般不易損壞,閥體容易損壞。自動(dòng)變速器油流經(jīng)閥體,閥體中的閥芯來回移動(dòng),控制油路,實(shí)現(xiàn)對(duì)壓力的控制。
The irregular shape is the valve body and the gear is the oil pump. Generally, the oil pump is not easy to be damaged, and the valve body is easy to be damaged. The automatic transmission oil flows through the valve body, and the valve core in the valve body moves back and forth to control the oil circuit and realize the control of pressure.
隨著使用時(shí)間的增加和自動(dòng)變速器油的老化,會(huì)使閥板和閥芯磨損,壓力不平衡,導(dǎo)致輸入軸離合器失效。
With the increase of service time and the aging of automatic transmission oil, the valve plate and valve core will be worn and the pressure will be unbalanced, resulting in the failure of input shaft clutch.
二、變速箱異響
2、 Abnormal noise of transmission
異常噪音來自振動(dòng)。雖然奧迪CVT變速箱的運(yùn)動(dòng)部件很多,但從維修經(jīng)驗(yàn)來看,差速器軸承發(fā)生故障的可能性較大。這是主減速器和差速器總成,上面安裝了兩個(gè)圓錐滾子軸承。
Abnormal noise comes from vibration. Audi has a lot of experience in the maintenance of the differential, but the possibility of CVT bearing failure is high. This is the main reducer and differential assembly, on which two tapered roller bearings are installed.
圓錐滾子軸承磨損時(shí),會(huì)引起總成轉(zhuǎn)動(dòng)中的偏移和擺動(dòng),從而產(chǎn)生振動(dòng),產(chǎn)生異響。
When the tapered roller bearing is worn, it will cause the deviation and swing in the rotation of the assembly, resulting in vibration and abnormal sound.
三、車輛打滑,加速碰撞
3、 Vehicle skidding, accelerating collision
奧迪CVT變速箱的滑動(dòng)部分主要是傳動(dòng)部分,即變速箱中的壓力缸與鏈條之間缺少壓緊力。
The sliding part of Audi CVT transmission is mainly the transmission part, that is, there is a lack of pressing force between the pressure cylinder and the chain in the transmission.
指示鏈條和鏈輪之間的相對(duì)位置。需要注意的是,鏈條與壓力缸的接觸位置是面積較小的一側(cè),而不是面積較大的正面。
Indicates the relative position between the chain and sprocket. It should be noted that the contact position between the chain and the pressure cylinder is the smaller side, not the larger front.
當(dāng)車輛打滑時(shí),CVT自動(dòng)變速箱維修時(shí)拆卸變速箱,可以看到鏈條和壓力缸表面有劃痕。具體原因有兩個(gè):一是鏈輪鏈接觸面磨損;二是液壓系統(tǒng)工作不暢,鏈條與鏈輪之間的壓緊力由液壓系統(tǒng)控制。
When the vehicle skids and the CVT automatic transmission is disassembled during maintenance, scratches can be seen on the surface of the chain and pressure cylinder. There are two specific reasons: first, the contact surface of sprocket link is worn; Second, the hydraulic system is not working smoothly, and the pressing force between the chain and sprocket is controlled by the hydraulic system.
液壓系統(tǒng)控制壓力缸和兩條帶之間的壓力,液壓系統(tǒng)的工作壓力由電子控制單元控制。
The hydraulic system controls the pressure between the pressure cylinder and the two belts, and the working pressure of the hydraulic system is controlled by the electronic control unit.
如果有滑倒。
If you slip.
1、檢查壓力缸表面是否磨損。如果有磨損,修理表面。如果不是,請(qǐng)換。
1. Check the pressure cylinder surface for wear. If there is wear, repair the surface. If not, please change it.
2、需要清理液壓控制系統(tǒng)、電腦板故障的情況下,無論這兩種異常不能解決故障。
2. When it is necessary to clean up the faults of hydraulic control system and computer board, these two abnormalities can not solve the fault.
四、儀表板紅屏
4、 Instrument panel red screen
當(dāng)奧迪使用CVT變速器時(shí),當(dāng)儀表板上出現(xiàn)紅色屏幕時(shí),可以確認(rèn)是變速器電腦板的故障。
When Audi uses CVT transmission, when the red screen appears on the instrument panel, it can be confirmed that it is the fault of the transmission computer panel.
綜上所述,奧迪CVT變速器存在四種故障。
To sum up, there are four faults in Audi CVT transmission.
1、車輛行駛時(shí),故障部位為輸入軸離合器;
1. When the vehicle is running, the fault part is the input shaft clutch;
2、變速箱異響,故障部位為差速器軸承。
2. The gearbox makes abnormal noise, and the fault part is the differential bearing.
3、車輛打滑,故障部位為鏈條打滑;
3. The vehicle slips, and the fault part is chain slip;
4、儀表板紅屏,故障部位為電腦板故障。
4. The instrument panel is red, and the fault part is the computer panel fault.
