Bearing for the electric car is equivalent to the bone joints in us, in the electric car driving process, the bearing is safe and greatly associated with our safety factor when riding. For electric vehicles, the greater the power of the bearing safety requirements are higher, the process of driving if the accident occurred in the bearing damage or the use of non-standard situation, we must promptly repair, because it relates to our late riding In the life of safety.
Electric car bearings is an important part of electric vehicles. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and to ensure its rotation accuracy.
According to the different friction properties of the moving components, bearings can be divided into two categories of rolling bearings and plain bearings. Rolling bearings have been standardized, serialized, but compared with the sliding bearing its radial size, vibration and noise, the price is higher.
Bearing damage:
1, the quality of their own bearings, steel is not up to standard material used poor!
2, the bearing exposed in the outer seal is not easy to easily into the water, such as the right side of the front wheel bearings; motor without the end of the brake cover bearing) and oil seal damage, the water will be washed under the butter within the bearing, resulting in poor lubrication and rust, Increase the friction to make the bearing wear "broken frame".
3, such as the impact of the wheel hit or shaft hardness is not enough to bend deformation, will make the bearing in the course of running force, will be grinding "inner" and grinding "cylindrical", so that the bearing force uneven damage!
4, bearing hole machining accuracy is not accurate round, slightly deformed bearings, running friction increases, leading to premature wear and tear bearing "war"!
Bearing in the case of excessive damage, the wheel will tilt, and then cause the vehicle in the process of running deviation, this is because the bearing in a direction of the bearing capacity decline, resulting in the direction of the electric car in the process of driving difficult to control The Serious point may occur when the wheel off, if the vehicle is in a high-speed state that the consequences will be disastrous, so the timely replacement of damaged bearings is necessary.
Replacement Note:
1, change the bearing when the end cover to check the oil seal, if the oil seal is not good, please give the replacement!
2, the factory bearing lubricants inside little or no oil, please put the bearing oil seal pry the appropriate addition of lubricants!
3, if the bearing hole loosening this type of failure, the safety considerations, should be replaced by the car ring or motor cover!
4, bearing installation is complete, please turn the wheels, check the wheel running is flexible and smooth, with or without difficulty or stuck phenomenon, if possible, there may be no bearing in place, please re-install! Or will sweep the Church, the operation is not flexible, forced to ride the bearing soon with "paralyzed" the!
5, inform the customer as far as possible not to the water place to ride, so as not to rust into the water.
Electric car bearings after a long grinding to wear, it is easy to damage, turn not smooth, turn abnormal sound, mostly for the pressure bearing trouble, repair as soon as possible to avoid small problems into a big failure.
