Oil, also known as engine oil, is an indispensable oil on the vehicle, its role in addition to the well-known lubrication and wear reduction, but also can play an auxiliary cooling, sealing leakage, rust, corrosion, shock buffering and other functions, if not it, the engine is easy to appear gas, rust, melting and even direct scrap.Like other oil on the vehicle, the oil also has an oil change cycle, and it is not a one-time addition that can be completely replaced, because the oil will also be oxidized, acidified, dissolved sludge, etc., during the use of the oil, which will not only make the

Oil seal is a common name for general seals. Simply put, it is the sealing of lubricating oil. Its main function is to seal oil, isolate the parts that need lubrication in the transmission parts and the output parts, so as not to let lubricating oil leak. When the oil seal is working normally, there is usually an oil slick between the lip and the shaft, which plays the role of sealing and lubrication.On the semi-trailer, there are many types of oil seals.

Hub bearing is one of the key components on the trailer, the main role is to carry weight, to provide accurate guidance for the rotation of the wheel end, not only to bear the axial load, but also bear the radial load.Hub bearings require regular maintenance, and the maintenance cycle of different brands also has certain differences. Under normal circumstances, the maintenance cycle of non-maintenance-free hub bearings is 1W km-5W km, and the maintenance cycle of maintenance-free bearings is longer, generally in 10W km-50W km.

With the continuous development of vehicle technology, the application of oil lubrication on the wheel end of the rear axle of the semi-trailer is becoming more and more extensive. Compared with ordinary grease lubricated hubs, the biggest advantage of oil lubrication is that it can achieve long maintenance and prolong the service life of wheel end accessories. Relevant data show that about 95% of trailer axles in the North American market use liquid gear oil lubrication technology.Lubricating oil and grease are two commonly used lubricants on vehicles.

Hydraulic retarder is an auxiliary braking device, also called hydraulic buffer, hydraulic retarder, engine retarder, etc., mainly composed of rotor, stator, working chamber, oil storage tank, heat exchanger, etc. Component composition.When the hydraulic retarder is working, it can lead the high-temperature working oil to the cooler for cooling, and then replenish the cooled oil through the oil pump, so that the vehicle can achieve constant speed or deceleration.According to different media, hydraulic retarders can be divided into two types: oil medium and water medium.

When it comes to brake failure, what problems will you think of first?

Brake failure is a very terrible problem, especially in the process of driving, once the brake failure consequences will be unimaginable. When it comes to the causes of trailer brake failure, the owners may first think of air road failure, brake pad/brake drum abnormal wear, valve body damage, brake overheating, serious overload and so on. In fact, there are many reasons for brake failure, some of which are even unexpected, such as lubricating grease.Lubricating oil is a necessity on the wheel end. Ordinary trailer axle generally uses grease.

Maintenance-free trailer axles appear more frequently on some high-end freight models, and the purpose of its application is to extend the maintenance cycle of the wheel end, reduce the frequency of maintenance, improve the efficiency of vehicle operation, and reduce the downtime caused by maintenance.The so-called maintenance-free axle is to replace grease lubrication with oil lubrication, fill the gear oil in the hub unit, the hub and the oil seal form a storage space for the gear oil, and soak the bearing in the gear oil to ensure its full lubrication capacity to achieve longer maintenance

Hydraulic retarder is an auxiliary braking device, also known as hydraulic buffer, hydraulic reducer, engine retarder, etc. It is mainly composed of several large components such as rotor, stator, working chamber, oil storage tank, heat exchanger, etc.When the hydraulic retarder is working, the high-temperature working oil can be directed to the cooler for cooling, and then the cooled oil can be replenished by the oil pump.
