What does a semi-trailer axle refer to? How to choose semi-trailer axle?

Semi-trailer is a common type of vehicle in long-distance cargo transportation, which has no driving force of its own, and needs to be connected with the tractor through the traction pin, using the driving force of the tractor to achieve driving. The semi-trailer transport volume is large, the transport of many kinds of goods, compared with the "single type" car can better improve the comprehensive economic benefits of road transport.

Semi-trailer axle refers to the axle assembly specially used in the semi-trailer, which is a key part of the vehicle chassis, usually including axle, brake and suspension and other accessory accessories, connected to the trailer body through the suspension, the wheels are installed at both ends of the axle, and its main role is to carry the load 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, safety performance and economic benefits of the semi-trailer during the long journey, it is very important to choose a high-quality trailer axle. Especially in the southwest of China and other places, long-distance transportation more Zhongshan road, rugged terrain, long, curved ramps are common, vehicle driving conditions are more severe, which puts forward higher requirements for the quality and performance of the trailer axle.

So, what aspects do owners pay more attention to when purchasing trailer axles? According to the relevant market research results, Xiaobian has made the following summary:

The pursuit of lightweight trailer axle design reduces self-weight and loads more

Especially after the implementation of the GB1589 new national standard, the weight of vehicles has become a sensitive issue for owners. The GB1589 new national standard gives a clear standard for the weight limit of trailers with different coaxial numbers, which has also become the basis for traffic management departments to control overload. How to achieve the weight reduction of the vehicle itself under the premise of meeting the load demand has become a more concerned issue in the industry.

Relevant data show that the weight of the three-axle trailer axle accounts for almost 20% of the total weight of the trailer, so the weight reduction of the trailer axle is a crucial factor in achieving the weight reduction of the trailer. However, compared with other components, it is more difficult to reduce the importance of the trailer axle, because one of the main functions of the trailer axle is load-bearing, if the pursuit of the reduction of the weight of the trailer axle affects the load-bearing performance, it is not worth the loss. How to realize the lightweight design of the trailer axle while ensuring that the load-bearing capacity of the trailer axle is unchanged or even stronger has become the key object of the trailer axle enterprises at home and abroad.

In this regard, DARO trailer axle has achieved good results, starting from the design and development process, focusing on the strong performance + lightweight goal, the raw material selection of 20Mn2 high-strength alloy seamless steel pipe, the use of one-piece heat treatment molding technology and powder + electrophoresis process, after repeated testing and testing, Successfully reduced the weight of the 13T trailer axle, which is in high demand on the market, by 15%-25%. While reducing its own weight, the high-strength load-bearing performance remains unchanged, eliminating problems such as bending and deformation.

Extend maintenance cycles to improve operational efficiency

In recent years, the logistics and transportation industry has continued to develop, and the mileage of vehicles has also been increasing. According to relevant research data, the annual mileage of long-distance transport semi-trailer is generally about 200,000-300,000 kilometers, and some logistics companies with sufficient supply of goods have even more vehicle mileage. Under such a high intensity transportation pressure, the maintenance and maintenance of the vehicle can not be ignored.

However, the trailer axle is different from other accessories, the workload of maintenance is relatively large, but also requires a certain amount of relevant knowledge and technology, even if it is sent to a special network, the average maintenance will take about 2-3 hours, which has a greater impact on the daily use of the owner.

On this basis, extending the maintenance cycle and reducing the difficulty of operation has gradually become an industry trend.

In response to this phenomenon, DARO Group introduced a longer maintenance cycle for the trailer axle, effectively reducing the owner's downtime, at the same time, simplifying the maintenance process, simpler operation steps, and improving operational efficiency.

Reliable quality + fair price Good reputation of users

Nowadays, there are more and more trailer axle manufacturers, and the trailer axle products on the market are also dazzling, from high-end to affordable, and then to the three small workshop products, countless.

More products, many owners of the concept of purchase has also changed, from the original single demand, such as quality, price, etc., to pay more attention to the comparison of the comprehensive quality of the product, both high quality, but also to the right price, but also good service, high product assurance. This puts forward higher requirements for trailer axle enterprises.

DARO Group, as the earliest trailer axle enterprise in China, has more than 20 years of experience in research and development and manufacturing of trailer axles, integrating research and development, design, production, sales and service. As a popular product in the market, DARO trailer axles are durable, long service life, excellent strength and toughness performance, and have successfully passed the ISO9001 quality management system certification. Compared with other brands of the same quality, DARO trailer axles are more reasonable and cost-effective, and have won widespread praise from users.

Trailer axle is a key part of semi-trailer, related to economic benefits, but also related to the safety of the vehicle. Whether it is lightweight design, quality reliability, cost performance or maintenance cycle, DARO trailer axles have achieved good results. In the future, DARO Group will continue to spare no effort to develop, produce and improve products to meet the needs of the majority of car owners.
