At the 16th Shanghai International Auto Show , the products exhibited by major commercial vehicle companies have become more and more mature. From the overall consideration of fuel economy, reliability, and comfort, to the appearance of lights and shrouds Other design layouts, internal engine selections, gearboxes and other major components have been continuously improved and optimized. Xiao Bian thinks that as the large-scale layout gradually matures, the attention to details will be promoted will become a major direction for future design and development. On this occasion, the Auman GTL Super Edition , FAW Jiefang J6 and Baihe Jiazhi are exhibited. The maintenance-free hub used by the long Dongfeng Liuqi New Lifelong H7 is actually a small change that will bring great convenience to users.

The bearing of the wheel hub directly affects the driving power of the vehicle and the safety of the user. The domestic non-maintenance-free hub tapered roller bearings need to be regularly replaced with the high-temperature grease applied on the top, which is what the user says is wiped butter. It plays a role in reducing the friction and wear of the bearing, ensuring the smooth running of the bearing, and it also needs to be maintained and observed from time to time. The maintenance-free tapered roller bearing of the hub is sealed in the gear oil by the Oil Seal. Compared to butter, gear oils have obvious advantages. They have better wear and load resistance, and have a long maintenance cycle. As long as there are no accidents, they can continue to be used even if they are used for one year or more than 100,000 kilometers. There is no need to disassemble the hub; it improves the user's ease of use, while also reducing the cost of use.

The technology of maintenance-free hubs is not a new technology. It has been widely used in foreign markets, especially in Europe and North America. The usage rate has reached more than 90%, but it is still rare in the domestic market. Only three were found on Xiao Bian. In fact, domestic trucks pay more attention to economy and practicality. Considering more of the user’s affordability and domestic market conditions, the price is definitely superior to imported trucks. This is why imported trucks cannot be used at home in the same way as imported passenger vehicles. The main reason for the market to occupy a large share. There are still big differences between domestic and foreign markets, but China’s economy is continuously improving. It can be clearly seen that domestic trucks are making progress, and our annual export volume is increasing year by year. The exhibition of the Dragon H7 by the gas station is also a vane of the domestic market, and many of the heavy trucks on display have reached world-class levels, indicating that domestic trucks are constantly making progress in the high-end market, and Chinese trucks are gradually moving towards the world, but from In terms of details, domestic trucks have many places that need to draw lessons from foreign countries in terms of harness layout and material selection. After all, the details determine success or failure, and small parts can actually determine the big market.

Oil seal is a mechanical components that used to seal oil (oil is the most common transmission system liquid material), It`s isolated the lubricated components with other components, not let the lubricate oil leakage. 

Oil Seal is generally divided into single-type and assembly type, assembly type is the skeleton and lip material can be free combination, generally used for special oil seals.

Oil seal can have different names, customary general rotary axis lip seal called oil seal, the static seal and dynamic seal (general reciprocating motion) was called seal parts.

The representative form of oil seal is TC type, is a double lips oil seal with a fully rubber coated and garter spring, generally speaking oil seal refers to TC skeleton oil seal, skeleton oil seal diagram see Figure:
