The performance of the transmission oil is very important to the transmission. Like the oil of the truck engine, it needs to be replaced regularly, but why it should be replaced, you may not necessarily understand, because the gear inspections are engaged with each other, and the gear ratio will be changed after changing the gear ratio.
The performance of the transmission oil is very important to the transmission. Like the oil of the truck engine, it needs to be replaced regularly, but why it should be replaced, you may not necessarily understand, because the gear inspections are engaged with each other, and the gear ratio will be changed after changing the gear ratio. The output power of the engine is transmitted, and huge torque needs to be transmitted between the various gears, so gear oil is needed to lubricate and cool the gears. And our trucks, especially those for long-distance transportation, have many gears, complex structure, high rotational speed, and high contact pressure between the gears and the occlusal contact surface between the gears. More attention should be paid to the inspection and replacement of the transmission oil.
Secondly, the gearbox should be overhauled regularly and in a timely manner.
After driving for a certain number of kilometers or returning from a long-distance drive, check whether the gearbox has oil leakage. Once the gearbox is found to have oil leakage and oil leakage, you should immediately find out the cause and check and repair it in time. Because the oil in the gearbox is engaged with each other through the gears, the oil at the bottom of the gearbox is splashed onto the surface of each gear, so the oil can adhere to the surface of the gears to form a protective oil film to ensure the oil between the gears. Good lubrication. If the oil in the gearbox is lower than the normal range, the oil cannot be splashed on the surface of each gear through the rotation of the gear. Due to the loss of oil film protection, the gear rotates at a high speed. At this time, the metal surface generates huge heat, and it is easy to damage the surface of the gear. If it is worn out, it will also ablate the surface of the gear in severe cases, making the gear unable to rotate.
In addition, the lubricating oil in the gearbox should be changed regularly.
Although the gearbox uses oil, there are also problems such as oxidation and deterioration. Since the temperature in the gearbox is higher than normal temperature, the lubricating oil will be oxidized. When the temperature is high, the viscosity of the lubricating oil will decrease and become very thin. Its adsorption capacity will also decrease, especially for some older vehicles, regular replacement is crucial.
Friendly reminder: Pay attention to the maintenance of the gearbox in daily use to extend its service life. If the truck gearbox fails, please go to the service station for maintenance in time. It is recommended to use special tools for gearbox maintenance to ensure the normal operation of the gearbox.
