Nowadays, the hub bearings of small passenger cars are mostly closed and integrated. The bearings of this structure have already added enough grease in the manufacturing process, so there is no need to add grease during use, because it is closed. Structure, such a car bearing does not require maintenance, even if we want to add grease is very troublesome.
In fact, our bearing damage is largely due to the lack of grease, but because the bearing material does not have the rolling surface of the fiber, which causes the bearing to generate noise during the rotation process. If there is no problem with the bearing itself, the bearing design of this structure The service life can reach more than 200,000 kilometers, so the bearing of this structure is not to be maintained. If it is broken, it can be replaced.
In fact, for the auto parts bearing, our current family car, auto parts bearings are not maintenance, because for our family car, its bearing load is not very large, and due to the advancement of bearing design technology, we The family car bearing can be designed as a maintenance-free bearing.
This is the rear wheel bearing that we have replaced from the family car. This type of bearing is not to be maintained!
But we also have bearings for auto parts that need to be maintained, such as our pickup trucks, a small part of heavy-duty off-road vehicles, the type they use is the bearings that need maintenance.
This kind of bearing is a bearing that needs to be repaired and oiled. He is usually installed on our heavy-duty vehicle and can bear a greater load! But in order to guarantee its service life, it needs maintenance every tens of thousands of kilometers, generally It is disassembled and cleaned, and then re-applied with grease to ensure bearing lubrication and heat dissipation under high load.
Then as a friend, why do some bearings need no maintenance?
In fact, because of this type of bearing, its design concept is different. His design goal was to design as a maintenance-free auto parts bearing. Moreover, the load of our family car is not very large, so the normal family car used, between 100,000 and 200,000 kilometers, may replace the car parts bearing.
The last oil seal will also be used on our auto parts bearings.
Our maintenance-free auto parts bearing it is equivalent to composing an assembly. It contains lubricating oil and bearing parts with exceptional strength. Seal our oil in the entire bearing body with our oil seal. When we drive, these lubricants will lubricate our bearing body. When we use it for a long time, the temperature of the bearing will become higher. Thinning, through our oil seal, seal these lubricants inside our bearing body, not letting it flow out
After we parked, these lubricants will slowly cool down and the viscosity will become higher. This will repeatedly lubricate our bearings. Such designed bearings can often use more than 100,000 kilometers.
And our kind of bearing, its design is very precise, because in order to prevent the inside of the lubricating oil from flowing out, if you want to maintain it, it will be very difficult, and it will affect the sealing of our entire bearing body!
Therefore, our bearings here do not need to be maintained, can be directly replaced with about 100,000 kilometers, and the price is not expensive! tens of dollars to two or three hundred yuan!
Now auto parts bearings generally do not require maintenance. Because the bearing is made of steel and processed through the quenching process, the outer metal film is very hard and wear-resistant.
There are many bearings used in auto parts, which are conical, cylindrical and beaded. It is too complicated to use the numbers 1, 2, 3, 4, etc., which is very complicated. If it is a professional, it is very simple. Therefore, I can only tell you that the bearing has an oil seal on both sides, an oil seal on one side, and a spring groove.
Auto parts bearings are mainly lubricated by oil (such as crankshaft bearings), grease lubricated (front wheel bearings), and gear oil (gearbox and rear axle inner bearings). The rear wheels are lubricated with butter and are also gear oil lubricated.
After the bearings are lubricated, the friction will be reduced and the temperature will be lowered. Under normal circumstances, it is no problem to drive 200,000 kilometers. Therefore, the general vehicle does not need to maintain the bearing.
However, there are several parts to note that the engine belt is tight, and the front and rear wheel bearings are particularly damaged by environmental factors due to long-term high-speed operation.
In fact, no maintenance does not mean that it will not be bad. Any metal is fatigued. In particular, when the quality of the lubricating oil is reduced or reduced, the bearing surface is ablated and damaged.
Nowadays, the inner and outer oil seals of most of the vehicle bearings are protected by iron sheets. Generally, oil leakage is not easy. Once damaged, the bearing components are replaced.
All in all, when driving, pay attention to some abnormal conditions of the vehicle, such as wheel shake, squeak, etc., you should pay attention to the bearing.
