How to choose the old driver semi trailer axle?

Semi-trailer is a common type of vehicle in long-distance cargo transportation. It has no driving force of its own, so it needs to be connected with the tractor through the traction pin and realize driving by the driving force of the tractor. Semi-trailer transport volume, transport a variety of goods, compared with the "monomer type" car can better improve the comprehensive economic benefits of highway transport.

Trailer axle refers to the axle assembly specially used in the semi-trailer, is a key part of the vehicle chassis, usually contains the axle, brake and suspension accessories, connected with the trailer body through the suspension, the axle is installed at both ends of the wheel, its main role is to bear the load of the trailer, maintain the normal driving of the vehicle.

The trailer axle is directly related to the load-bearing, braking and driving of the trailer axle. In order to fully guarantee the attendance rate, safety performance and economic benefits of the semi-trailer in the long journey, it is very important to choose a high-quality axle. Especially in the southwest of our country, the long-distance transportation of mountain road more, rugged terrain, long, curved slopes are common, vehicle driving conditions are more serious, this puts forward higher requirements for the quality and performance of trailer axles.

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

Pursue lightweight axle design to reduce dead weight and load more

Especially GB1589 after the implementation of the new national standard, the weight of the vehicle has become a sensitive issue for the owners. GB1589 new national standard for different number of trailer weight limit gives a clear standard, which has become the basis for traffic management departments to deal with overload. How to achieve the weight reduction of vehicles 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 axle of the three-axle trailer almost accounts for more than 20% of the total weight of the trailer, so the axle weight reduction is a crucial factor to achieve the weight reduction of the trailer. However, compared with other components, it is more difficult to reduce the importance of the axle, because one of the main functions of the axle is to bear weight. If the pursuit of the reduction of the weight of the axle affects the bearing performance, it is not worth the loss. How to realize the lightweight design of the axle while ensuring the bearing capacity of the axle remains unchanged or even stronger has become the key target of domestic and foreign axle enterprises.

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

Extend the maintenance cycle to improve operational efficiency

In recent years, the logistics transportation industry has been developing, and the mileage of vehicles has been increasing. According to relevant research data, the annual mileage of semi-trailer for long-distance transportation is generally about 200,000-300,000 kilometers, and the mileage of some logistics enterprises with sufficient supply of goods is even more. In such a high intensity transport pressure, vehicle maintenance and maintenance is not negligible.

However, the axle is different from other parts, the maintenance workload is relatively large, but also needs a certain amount of relevant knowledge and technology, even if it is sent to the 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, DARO introduced a longer maintenance cycle for axles, which effectively reduces downtime for car owners, simplifies maintenance processes, and improves operational efficiency.

Reliable quality + fair price good reputation of users

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

More products, many owners of the concept of purchase has changed, from the original single demand, such as quality, price, to pay more attention to the comprehensive quality of the product comparison, not only to high quality, but also to the right price, but also good service, high product assurance. This puts forward higher requirements for axle enterprises.

DARO Group, as the representative of senior axle enterprises in China, has more than 20 years of experience in axle research and development and manufacturing, integrating research and development, design, production, sales and service. As a popular product in the market, DARO axles are strong and durable, long service life, excellent strength and toughness performance, and have successfully passed ISO9001:2008 quality management system certification. Compared with other brands of the same quality, DARO axle price is more reasonable, cost-effective, has won widespread praise from users.

Axle is a key part of semi trailer, which is related to economic benefit and safety of vehicle. In terms of lightweight design, quality reliability, cost performance and maintenance cycle, DARO axles have achieved great 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.
