Exploring the secrets of Chinese and foreign trailer axles: disc brakes, lightweight and air suspension are the keys
Publish Time: 2024-11-08
In the modern freight transportation industry, trailer axles are key components connecting vehicles and the ground, and their performance directly affects transportation efficiency, safety and operating costs. In recent years, with the continuous advancement of technology and increasingly strict regulations, technologies such as disc brakes, lightweight and air suspension have become the three key words for the development of trailer axles.Disc brakes: the new benchmark in braking performanceDisc brakes, that is, disc brakes, have significant advantages over traditional drum brakes in terms of light weight, fast heat dissipation, sensitive response, and strong resistance to thermal attenuation and water attenuation. These characteristics make disc brakes play an important role in improving vehicle braking performance and ensuring driving safety.First of all, the disc brake eliminates the 360° brake drum, which greatly improves the vehicle's weight. At the same time, there is no need to install a water spray device, which further improves the vehicle's cargo capacity. Secondly, the components of the disc brake braking system are more simplified, the structure is simpler, and the braking response speed is faster. Under emergency braking, ABS (anti-lock braking system) and EBS (electronic braking system) can be fully exerted. Optimal performance. In addition, the open wheel end design of the disc brake allows for high ventilation efficiency, fast heat dissipation, and is not prone to thermal attenuation under frequent and continuous braking. After passing through water, the braking performance can be restored by pressing the brake pedal several times in succession.However, disc brakes also have some limitations. Due to its structural reasons, the braking force is insufficient compared to that of a drum brake bridge, which limits the use of disc brakes to a certain extent. In some situations where the load mass is large or there is overloading or uneven loading, disc brakes may not be suitable for use. In addition, the open wheel end results in exposed brake discs, brake pads and other components, which are easily affected by splashing mud, sand and gravel, and are not as durable as drum brake bridges in harsh environments.Lightweight: the key to improving transportation efficiencyLightweighting is one of the important trends in the current development of trailer axles. With the implementation of the new GB1589 standard and the continuous strengthening of efforts to control overloading of trucks in various places, the demand for lightweight vehicles in the freight transportation industry has gradually increased. Lightweight trailer axles not only help reduce vehicle weight and increase load capacity, but also effectively reduce fuel consumption and improve transportation efficiency.In terms of lightweight design, domestic and foreign companies have adopted advanced materials and technologies. For example, a company has launched a lightweight air suspension axle. By optimizing the axle beam structure, eliminating redundant parts, and adopting new processes, it has effectively reduced the axle's weight while improving its bending and torsion resistance. In addition, the weight of the disc and drum products has also been reduced to 460 kg and 470 kg respectively, which is 100 kg lighter than the same type of products, helping to reduce the overall weight of three-axle trucks by 300 kg.Air suspension: improves ride comfort and cargo protectionAs one of the important configurations of modern commercial vehicles, air suspension has significant advantages such as light weight, low dead weight, excellent shock absorption effect, and good cargo protection effect. Compared with traditional leaf spring suspension, air suspension can better adapt to complex road conditions, improve ride comfort and cargo protection.The height of the air suspension can be adjusted freely, allowing single or multi-bridge lifting to facilitate loading and unloading of cargo. At the same time, air suspension can also reduce tire wear, protect vehicle chassis components, and reduce overall vehicle costs to a certain extent. European air suspension and American air suspension have their own characteristics in structure and performance. The European air suspension guide arm has a strong flexible structure and good vibration filtering performance; the American air suspension has a stable rigid connection structure and good lateral support. Under the background of complex domestic transportation road conditions and heavy loading habits, European-style air suspension has a wider range of applications.Comparison of the development status of trailer bridges between China and foreign countriesIn the development of trailer axle technology, Chinese and foreign companies have their own strengths and weaknesses. Domestic companies have made significant progress in the application of lightweight, disc brake and air suspension technologies. For example, TND Axle is a national high-tech group specializing in the R&D, design and manufacturing of trailers, semi-trailers and other heavy vehicle parts. The company's performance is close to or reaching the international advanced level. At the same time, domestic companies have also applied for a number of patented technologies through independent research and development and innovation, such as anti-explosion brake drums for heavy-duty axles, airbag brackets and guide arm split designs for air suspensions.
Disc brakes, lightweight and air suspension, as the three key words in the current development of trailer axles, not only improve the vehicle's braking performance, transportation efficiency and ride comfort, but also promote the overall development of the cargo transportation industry. Chinese and foreign companies have their own strengths and weaknesses in these technical fields. Through continuous technological innovation and market competition, they have jointly promoted the progress and development of trailer axle technology. In the future, with the continuous advancement of technology and increasingly strict regulations, trailer axle technology will develop in a more efficient, safe and environmentally friendly direction.About TNDTND Axle is a national high-tech group company specializing in the R&D, design and manufacturing of heavy vehicle parts such as trailers and semi-trailers.
