With the continuous development of society, Electric Sedan Car are appearing more and more in our lives. Friends who have driven Electric Sedan Car will find that Electric Sedan Car start much faster than fuel vehicles. Many times friends around me will ask what kind of lubricant is used in the motor of Electric Sedan Car? Today our Electric Car manufacturer is here to introduce it to you.
1. Electric Sedan Car do not have an engine, so they do not need oil or filters. The bearings at both ends of the motor itself are filled with high-temperature grease. There is no running-in concept for the bearings and no metal particles are produced. The sealing of the motor is very good, and external pollutants will not enter the motor. Generally, there is no need to replace the grease, but it still needs to be inspected regularly. If there is any damage to the seal, it needs to be repaired in time.
2. Good lubrication of the motor should be ensured during operation. When a general electric motor runs for about 5,000 hours, the grease should be replenished or replaced. If the bearing is found to be overheated or the lubrication deteriorates during operation, the hydraulic grease should be replaced in time. When replacing the grease, the old lubricating oil should be removed, and the oil grooves of the bearing and bearing cap should be cleaned with gasoline, and then ZL-3 lithium-based grease should be filled into 1/2 of the cavity between the inner and outer rings of the bearing (for 2 poles) and 2/3 (for 4, 6, and 8 poles).
3. Commonly used greases for Electric Car motor circulation cooling system bearings include calcium-based grease, sodium-based grease, calcium-sodium-based grease, lithium-based grease, aluminum-based grease and molybdenum disulfide grease, etc., of the same type The properties of grease also vary greatly depending on the brand, so please pay attention when selecting. In principle, greases of different brands cannot be mixed. Mixing greases containing different types of thickeners will destroy the grease structure.
The emergence of Electric Sedan Car has provided great help to our lives. It has also made a great contribution to our environmental protection. The main maintenance items that need to be replaced include brake oil and coolant and the grease of the four wheel hub axles. , of course, if it is hydraulic power assist, there is also steering oil.
