Air suspension has many benefits but is too delicate. If you don't know how to maintain it, it will only be scrapped in advance.

With the prevalence of the trend of light quantification in recent years, air suspension has appeared more and more frequently on freight vehicles. Especially with the promotion and support of relevant regulations, air suspension has become a major selling point for many car companies. At the same time, compared with traditional leaf springs, air suspension does have incomparable advantages in many aspects. Although there are some flaws in strength and durability, it is still popular.Air suspension is mainly composed of elastic elements, shock absorbers, and guide mechanisms. This is similar to the traditional suspension system. The biggest difference is the upgrade of its elastic elements. Air springs are used as elastic elements. At the same time, electronic control functions and air pumps and other components are added, so that the suspension has active adjustment capabilities.The advantages of air suspension are mainly the following:1. Excellent shock absorption effectAir suspension uses compressible air as elastic medium, and its shock isolation effect is better than leaf spring. It can greatly absorb bumps and impacts from the road, which can not only improve driving comfort, but also enhance the protection of goods. Especially when transporting hazardous chemicals or fragile and high-value-added goods, it can ensure the constant height of the cargo compartment as much as possible, reducing or avoiding cargo damage caused by bumps.2. Lighter weightLightweight is the most obvious advantage of air suspension, especially compared with traditional leaf spring suspension. In the current situation where traffic control departments strictly control vehicle load, lighter weight means that more goods can be loaded, and it can also improve fuel economy and reduce comprehensive vehicle costs.3. Height can be freely adjustedAir suspension can realize the lifting and lowering of a single bridge or the whole vehicle. When the vehicle returns empty, the single bridge can be lifted, which further reduces tire wear and saves fuel. On the other hand, freight vehicles often need to stop in front of the cargo platform to load and unload goods. The height of the cargo platform in different cargo yards may not be uniform. The air suspension can adjust the height of the vehicle body to match different cargo platforms, which is more convenient for loading and unloading goods.
4. Reduce tire wearThe connection between the air suspension and the wheel and frame is a soft connection. When the vehicle encounters poor road conditions, the fit between the tire and the road is softer, unlike the hard collision of leaf spring suspension, so it is more conducive to reducing tire wear and saving tire replacement costs. Conversely, while protecting the tire, the air suspension can also play a certain protective role on the road.5. Protect chassis componentsThis is also due to the excellent shock absorption effect of the air suspension. The impact and bumps from the road are reduced, the loosening of fasteners on the vehicle chassis is greatly reduced, and the wear of chassis components can be improved to a certain extent, extending its service life.How should the air suspension be maintained during use?1. Strictly control the working pressureUnder normal circumstances, the design pressure of the airbag is about one-third of the burst pressure. It is worth noting that whether the working pressure is too high or too low, it will cause premature damage to the airbag, so it needs to be controlled within a strict range during use.2. Do not exceed the use rangeIn order to ensure the service life of the air suspension, remember not to exceed the use range clearly indicated in its performance parameter table during use.3. Pay attention to the use environmentTry to use the air suspension in a dry, cool and ventilated environment, avoid exposure to the sun and contact with acids, alkalis, oils, organic lubricants, etc., do a good job of daily cleaning, and reduce damage to the surface of the airbag. When facing complex road conditions, try to slow down and drive slowly to avoid splashing sand and gravel from damaging the airbag or the precision parts inside the suspension.4. Pay attention to parking the vehicleWhen parking a vehicle with air suspension, make sure that the vehicle is stopped before pulling up the handbrake to avoid the airbag from rebounding. In addition, try to park the car on a stable road, and do not park the car on the curb or on uneven places in front, back, left, and right, otherwise the airbag will be unevenly stressed and easily damaged in the long run.5. Daily inspection and regular maintenanceIt is recommended to regularly check whether there are faults and hidden dangers in the air pump, distribution valve, and pipeline interface. If there are no hidden dangers but the fault code prompt appears, a dedicated computer should be used for comprehensive inspection, and the airbag should also be checked for abnormalities. If found, a professional maintenance point should be contacted for repair or replacement.Air suspension is easy to use, but it must also correspond to the use conditions. If the owner usually pulls a large amount of goods and often runs on bumpy mountain roads or downhill roads, then don't follow the trend to choose air suspension. Even if it is barely used, subsequent damage and maintenance frequency are inevitable. In addition, it is not good for safety. The traditional leaf spring suspension is the first choice. However, for green passes, flowers, glass ceramics, electronic instruments, hazardous chemicals, or standard load transportation that often runs on highways and national highways, it is more appropriate to choose air suspension. At this time, it is particularly important to choose a regular brand, and don't be greedy for small profits, because the quality of the air suspension is up to standard, which can bring more safety and benefits.Among the many air suspension brands, TND Axle is undoubtedly a trustworthy choice. TND Axle is a national high-tech group company specializing in the research and development, design and manufacturing of heavy-duty vehicle parts such as trailers and semi-trailers. It has obtained multiple international quality standard certifications such as IATF 16949:2016. Its main products include American axles, German axles, air suspensions, bogie suspensions, mechanical suspensions and other trailer parts, with an annual output of about 100,000 sets of axle series and 20,000 sets of suspension series. TND Axle has innovated and improved on the basis of military technology, creating a new era of seamless steel tube hot extrusion one-piece thickened axles. This technology not only improves the strength, stiffness and fatigue life of the axle beam, but also reduces the risk of fatigue fracture of the axle.In order to ensure the excellent quality of its products, TND Axle also has its own patented thermoforming machines and other advanced equipment, such as fatigue testing machines, ultrasonic flaw detectors, Brinell hardness testers, thickness gauges, spectrometers, metallographic analyzers, coordinate measuring machines, etc. These equipment are supported by professional engineers and strict quality control teams in the R&D department of TND Axle to ensure that each set of air suspension is strictly inspected and tested to achieve the best use effect.Therefore, when you are considering choosing an air suspension, you might as well choose a regular brand like TND Axle to ensure your transportation safety and efficiency. TND Axle's industry experience has won the trust and welcome of the majority of users. We will continue to provide high-quality trailers, semi-trailers and other heavy-duty vehicle parts and good after-sales service to new and old customers for common development!
