Causes and prevention of abnormal noise of EQ1108G automobile transmission bearing


Setup and call of the driver seat and exterior mirror memory function of the Passat 6 sedan â–¡ Zhang Jugan 1 memory The position of the driver's seat and the exterior mirror when driving normally 17, 55 red button is pressed; adjust the driver's seat and From the outside mirror to the most suitable position, press the memory button on the left side of the driver. It is recommended to start and hold from the first button until the call is heard. Repeat this step to set the other two buttons. 4 Driver When the memory button on the seat is set, immediately turn off the ignition switch and pull out the ignition key. Press and hold the open button on the key in 53 until the sound is heard, and the key memory setting is completed.
Repeat steps 3 and 4 to set the key without remote control and you cannot set it.
2Setting and memorizing the pre-adjusted rear view mirror position 1 After the memory button setting on the driver's seat is completed, switch the exterior mirror adjustment knob to the right outer mirror adjustment position, and shift the gear. The rod is hung in the reverse position, and the right outer mirror position is adjusted so that the driver can see the rear side of the vehicle and the ground 3 from the inside of the vehicle when the vehicle is reversed, and press a memory button on the left side of the driver's seat and hold it until listening. The tweet is clearly set and the set position is memorized by the corresponding memory button.
When the position of the exterior mirror is reversed, the exterior mirror adjustment knob should be switched to the right exterior mirror adjustment position.
2. Call the preset memory position. When the driver's door is not closed, press the set memory button on the driver's seat. The driver's seat and the exterior mirror will automatically run to the preset. Position; when the driver's door is closed, press and hold the set memory button on the driver's seat until the driver's seat and the exterior mirror are automatically adjusted to the preset position; When the driver's door is closed, press the remote control's open button to open the driver's door, and the driver's seat will automatically adjust to the position remembered by the key. The two master keys can remember two positions.
Note that the pre-set memory position can only be recalled when the ignition switch is off, red, 6, 31, and the switch is depressed. Port, 08 type car assembler type 130 6-speed transmission, synchronizer shifting. The gears and the sixth gear are shifted by the inertial gear-toothed synchronizer, and the reverse gear is shifted by the sliding gear sleeve. The needle bearing on the shaft cooperates with the shaft.
The transmission bearing works under high-speed and heavy-duty conditions for a long time, especially the bearings that are mounted on the upper part of the housing by the splash-lubricated bearing. When the gear oil is deficient in insufficient oil or used improperly, the lubrication condition is deteriorated, which is prone to ablation fatigue. Damage such as flaking and cracking, so that the axial radial clearance of the bearing is too large, and abnormal noise is generated during operation. In order to ensure the normal operation of the transmission, it is necessary to take targeted and effective preventive measures on the basis of mastering the cause of the abnormal noise of the bearing.
1. Causes of abnormal noise in the bearing 1 Gear oil deteriorates. The gear oil has a long service life and deteriorates. It is difficult to form a good lubricating oil film, which causes the bearing wear to be intensified, the gap is increased, and an abnormal noise is generated during operation.
The gear oil is not enough. The gear oil quantity is insufficient, the lubrication cooling strength is not enough, the bearing and the matching journal or gear temperature increase rapidly, the expansion deformation occurs, the metal directly contacts, causing the bearing to ablate and peel off, the gap increases, and the noise is abnormal during operation. .
Improper use. In order to save fuel, some drivers often turn off the ignition switch to idle, or when the car fails to pull a long distance, the faulty vehicle is coasted. At this time, the engine is not working, and the power is reversely transmitted. The route is the drive wheel half shaft differential reducer drive shaft transmission shaft hub hub synchronizer. Since the shaft and the gears of the various gears are assembled by needle bearings, the shaft rotates, but the gears of the gears do not rotate, so the gear oil cannot be stirred, the bearings are not lubricated, and the bearings are abnormally worn. Big, abnormal noise when working.
2. Measures to prevent abnormal noise of bearings Add gear oil according to the specified grade and capacity. Check the quality of the gear oil and the height of the liquid level frequently. It is found that the deterioration should be replaced in time. When the liquid level does not meet the standard degree, it should be replenished in time.
It is strictly forbidden to slide in the air after the flameout.
When it is necessary to tow a long distance, after each distance of the driving section, the corresponding gear position should be hung according to the vehicle speed, the transmission intermediate shaft is operated, the gear oil is agitated, the components are fully lubricated, and the transmission shaft or the half shaft can be removed and pulled. The six reverse gears are always meshing gears, all of which are rolled by 9 turns, 匪, □ Ma Wei
