What do car owners often refer to as "semi-trailer axles"?
Publish Time: 2025-01-02
Semi-trailers are a common type of vehicle in long-distance cargo transportation. They have no driving force of their own and need to be connected to the tractor through a towing pin to use the driving force of the tractor to achieve driving. Semi-trailers have large transportation volume and can transport a wide variety of goods. Compared with "mono-type" vehicles, they can better improve the comprehensive economic benefits of road transportation.Semi-trailer axles refer to axle assemblies specifically used on semi-trailers. They are a key component of the vehicle chassis. They usually include accessories such as axles, brakes and suspensions. They are connected to the trailer body through suspensions. Wheels are installed at both ends of the axles. Their main function is to carry the weight of the trailer and maintain the normal driving of the vehicle.
The axle is directly related to the load-bearing, braking and driving of the semi-trailer. In order to fully guarantee the attendance rate, safety performance and economic benefits of the semi-trailer during long journeys, it is very important to choose a high-quality axle. Especially in southwest China and other places, there are many mountain roads in long-distance transportation, the terrain is rugged, long and curved ramps are common, and the vehicle driving conditions are severe, which puts higher requirements on the quality and performance of trailer axles.So, what aspects do car owners pay more attention to when purchasing axles? According to the results of relevant market research, the editor has made the following summary:Pursue lightweight design of axles to reduce deadweight and load more goodsEspecially after the implementation of China's new national standard GB1589, the deadweight of vehicles has become a sensitive issue for car owners. The new national standard GB1589 gives clear standards for the weight limit of trailers with different axle numbers, which has also become the basis for traffic management departments to control overloading. How to achieve the weight reduction of the vehicle itself while meeting the load requirements has become a more concerned issue in the industry.Related data show that the weight of the axle of a three-axle trailer accounts for more than 20% of the total weight of the trailer. Therefore, the weight reduction of the axle is a crucial factor in achieving the weight reduction of the trailer. However, compared with other components, the weight reduction of the axle is more difficult, because one of the main functions of the axle is to bear weight. If the pursuit of weight reduction of the axle affects the load-bearing performance, it will not be worth the loss. How to achieve lightweight design of axles while ensuring that the axle load remains unchanged or even has a stronger load-bearing capacity has become the focus of domestic and foreign axle companies.In this regard, TND axle has achieved good results. Starting from the design and development stage, it focuses on the goal of strong performance + lightweight, and has innovated and improved on the basis of military technology, creating a new era of seamless steel pipe hot extrusion one-piece thickened axles. This advanced technology can greatly improve the strength, stiffness and fatigue life of the axle beam and reduce the risk of fatigue fracture of the axle.Extend maintenance cycle and improve operational efficiencyIn recent years, the logistics and transportation industry has continued to develop, and the mileage of vehicles has continued to increase. According to relevant survey data, the annual mileage of semi-trailers for long-distance transportation is generally around 200,000-300,000 kilometers, and the mileage of vehicles of some logistics companies with sufficient cargo sources is even higher. Under such high-intensity transportation pressure, vehicle maintenance and care cannot be ignored.However, axles are different from other accessories. The maintenance workload is relatively large and requires certain relevant knowledge and technology. Even if they are sent to special outlets, the average maintenance takes about 2-3 hours, which has a great impact on the daily use of car owners.On this basis, extending the maintenance cycle and reducing the difficulty of operation has gradually become an industry trend.In response to this phenomenon, TND axle launched our own patented thermoforming machine and other advanced equipment, including: fatigue testing machine, ultrasonic flaw detector, Brinell hardness tester, thickness gauge, spectrometer, metallographic analyzer, coordinate measuring machine, etc., and has been supported by professional engineers and strict quality control teams in our R&D department. Axles with longer maintenance cycles effectively reduce the downtime of car owners. At the same time, they simplify the maintenance process, make the operation steps simpler, and improve operational efficiency.
Reliable quality + fair price and good user reputationNowadays, there are more and more axle manufacturers, and the axle products on the market are also dazzling, from high-end to affordable, to small workshop products without three products, countless.With more products, many car owners' purchasing concepts have also changed, from the original single demand, such as quality and price, to more emphasis on the comprehensive quality of the product comparison, not only high quality, but also reasonable price, good service and high product guarantee. This puts higher requirements on axle companies.TND Axle is a national high-tech group company that has been engaged in the research and development, design and manufacturing of heavy-duty vehicle parts such as trailers and semi-trailers for more than 16 years, integrating research and development, design, production, sales and service. As a popular product in the market, TND Axle is sturdy and durable, has a long service life, and has excellent strength and toughness performance. It has obtained IATF 16949:2016 and other international quality standard certifications. Compared with other brands of the same quality, TND Axle has a more reasonable price and higher cost performance, which has won wide praise from users.The axle is a key component of the semi-trailer, which is related to economic benefits and vehicle safety. Whether it is lightweight design, quality reliability, cost performance or maintenance cycle, TND Axle has achieved good results. In the future, TND Axle will continue to spare no effort to develop, produce and improve products to meet more needs of car owners.
