In our daily life, we sometimes see or hear the word "towing a trailer". What is "towing a trailer"? Specifically, "towing a trailer" generally has two interpretations:

One is a noun, which refers to a freight vehicle. This vehicle has no driving force and its main function is load-bearing. It needs to drive with the help of the traction of the front of the vehicle. It can also be called a trailer, such as the trailer or semi-trailer we often say.

The other is a verb, which refers to the vehicle towing the trailer on the road, such as "the vehicle shall not tow the trailer during the internship period" mentioned in the traffic regulations.

What is towing a trailer? How can the trailer achieve cost reduction and efficiency increase through the axle?

Trailer is a kind of vehicle used more and more in the logistics and transportation industry. Especially with the continuous development of China's transportation industry, trailer is gradually favored by more and more logistics companies because of its large transportation capacity and wide range of goods.

On the other hand, China's road transportation market is huge, but the terrain and climate are diversified, and the road conditions are more complex. In addition, the continuous introduction of relevant standards and regulations put forward higher requirements for the reliable travel, attendance and transportation efficiency of trailers, which also makes more and more trailer parts manufacturers move towards the direction of cost reduction and efficiency efficiency.

As one of the key components of the trailer, can the axle also reduce cost and increase efficiency?

The answer is yes, just like the gb7258-2017 standard for motor vehicle operation safety technical conditions issued last year, which requires the installation and use of disc brakes and air bag suspension for three axle barrier plate and warehouse grid semi-trailer, which is actually a means to reduce cost and increase efficiency.

The axle design is lightweight to achieve multiple loads within the specified range

In the design and production of trailers and tractors, lightweight has always been an important means to reduce costs and increase efficiency. After all, only the dead weight of the vehicle is reduced, more weight space can be left to load goods within the specified range.

According to the relevant data, the axle weight of a three axle trailer is almost more than 20% of the total weight of the trailer. Therefore, for the weight reduction of the trailer, it is very important to realize the lightweight of the axle and axle.

However, compared with the lightweight design of other components, it is more difficult to reduce the weight of the axle, because the axle itself is a load-bearing component. While realizing its own weight reduction, it is also necessary to ensure that its load-bearing performance is not reduced. Otherwise, the gains may outweigh the losses. It will not only save fuel consumption and increase use efficiency, but also lead to reduced load and reduced transportation revenue. This puts forward quite high requirements for the raw materials, production technology and production technology of the axle. Darong axle is a typical representative among the leaders in lightweight design. The weight of 13T axle designed and produced by Darong group is about 15% lower than that of axle of the same specification in peer manufacturers. 20Mn2 high-strength alloy seamless steel pipe is combined with one-piece heat treatment molding technology and powder spraying + electrophoresis process, which not only reduces the weight of axle, but also solves the problems of axle deformation and bending under high-strength load, The strength and toughness are greatly improved.

Protect goods and tires and reduce vehicle use costs

I'm afraid it's the tire that has the highest maintenance frequency among the various accessories of the trailer. After all, the weight borne by the axle from the body should be distributed to all wheels. If the tire fails, it may increase fuel consumption or affect driving, or it may lead to safety accidents, so the tire problem can't be underestimated.

According to relevant statistics, in the operation cost of the logistics fleet, the tire cost directly accounts for 4% - 5%, and the tire participation cost is about 35%. Therefore, protecting the tire and reducing its maintenance frequency is an important way to reduce the cost and increase the efficiency of the trailer. Axle, as an axle assembly, is one of the factors that directly affect the tire.

The axle produced by Darong group fully considers the actual needs in design and adopts the outward 1-degree design. Although it seems to be only a small angle, it can make the tire better fit the road when the vehicle is fully loaded, with more uniform stress, firmer grip and greatly improved traction efficiency.

The air suspension produced by Darong group adopts 3D forging technology, adds special shock absorbers to improve toughness, and has stronger cushioning force, which can better protect goods and increase seismic performance. The types of goods that car owners can transport have been expanded to realize "no picking of goods".

The maintenance operation is convenient to reduce the daily maintenance cost

As a cargo transport vehicle, the daily maintenance of various accessories on the trailer is indispensable, especially the axle system, which is directly related to the safety and benefit of the trailer, and regular maintenance can not be ignored.

However, on another level, if the owner sends the vehicle to a special maintenance network for maintenance, the single time is about 2-3 hours. If it is repaired 5-6 times a year, it will have a great impact on the attendance rate and bring pressure on the cost to the owner.

However, safety is no trivial matter, and daily maintenance and maintenance are absolutely indispensable. In response to this phenomenon, Darong group has developed and produced axles with longer maintenance cycle, which simplifies the maintenance process, effectively reduces users' shutdown time and improves operation efficiency.

Longer service life and higher value of used trailers

The axle is the core component of the trailer. When buying a new car or a second-hand car, it is an object that buyers pay more attention to.

The axle produced by Darong group has outstanding performance in lightweight design, protecting goods, protecting tires and simplifying maintenance procedures. At the same time, it has also made great progress in prolonging service life. It can not only better ensure safety in vehicle use, but also give vehicles higher economic benefits in the process of vehicle rotation.
