With the continuous improvement of the development level of logistics and transportation industry and the continuous improvement of relevant laws and regulations, car owners have higher and higher requirements for the production technology of trailer bridges. Many brands are committed to building their own axles into unique selling points, such as lightweight, maintenance free, high load-bearing and other labels emerge in endlessly.

Today, let's focus on the analysis of which is more practical, the axle that focuses on lightweight and the axle that focuses on high load-bearing.

1. Lightweight axle: lighter weight.

Lightweight is a term rising in recent years, or it can be said that it is a development trend of trailer industry. Reducing the axle weight can help save fuel, reduce vehicle costs and improve operation efficiency to a certain extent.

For example, for the disc axle, the exposed brake disc replaces the 360 ° wrapped brake drum, which is naturally lighter in weight. If it is matched with lightweight materials and accessories, and the internal structure design and manufacturing process are optimized, its self weight advantage is more obvious.

For another example, German axle is also a representative type of lightweight axle, especially its special structural design of axle head and "three-piece" welding treatment of axle beam, which makes it generally superior to other axles in saving fuel and reducing tire damage.

It is worth noting that the lightweight of the axle must be based on safety. In order to pursue the lightweight of products, some bad manufacturers blindly reduce the thickness and strength of raw materials, or arbitrarily change the product design and structure, which is not desirable. Car owners also need to polish their eyes when selecting and purchasing.

2. High load bearing: stronger and more resistant to construction.

Although many lightweight axles in the market can give consideration to load-bearing while realizing lightweight, many car owners, especially those who often transport heavy goods, prefer those with sufficient materials and more compact axles when consulting the axles.

For example, the most prominent feature of American axle, which has the widest coverage in the domestic market, is its good heavy load performance, which is inseparable from its "one-piece" axle body casting technology and the design of axle head with higher thickness and regular shape.

Another example is the low flat axle. As a typical special axle for heavy-duty vehicles, its axle beam is much thicker than other axle types, and it is not easy to crack or deform under high-strength load-bearing.

Another example is the special axle for heavy cargo distribution - three line six axle axle axle, whose maximum bearing capacity can reach about 80t, which requires that its axle beam and even accessories must adopt special materials with higher thickness and strength.

But correspondingly, these axles are not very dominant in the field of lightweight.

As for which kind of lightweight axle or high load-bearing axle is more practical, "honey of a and arsenic of B", we still need to see whether it meets our own use needs.

Transport vehicles suitable for different types of axles:

1. Disc axle

(1) Three axle fence / bin grid car: according to gb7258-2017 standard, three axle fence and bin grid semi-trailer are models with mandatory disc axle, which will affect their license plate or road driving.

(2) Transportation of precision instruments / valuables: due to the particularity of transported goods, the requirements for transportation are also relatively strict. Disc axle braking is sensitive and more stable, which can avoid collision or large amplitude vibration of goods during transportation.

(3) Transportation of dangerous goods: compared with ordinary goods vehicles, dangerous goods vehicles have a higher risk factor. The use of disc axle can reduce accidents caused by uneven distribution of vehicle braking force, slow heat dissipation of brake and other factors as much as possible.

(4) Mountain transportation: disc axle with hydraulic retarder and ABS / EBS system can not only make the vehicle achieve the best braking effect in a shorter distance, but also prolong the service life of friction plate, reduce tire loss, reduce vehicle weight, and fully save energy and reduce consumption.

2. American axle

(1) Transportation of ordinary goods: the price of American axle is relatively low, the accessories are common in the industry, the design is relatively simple, and the replacement and maintenance are relatively convenient. It can be widely used for the transportation of all kinds of ordinary goods.

(2) Transportation of heavy goods: the American axle usually adopts the "one-piece" casting process. The design of the shape of the shaft head is regular, and the thickness of the bearing connection is higher, which is more suitable for the transportation of heavy goods.

3. German axle

(1) Long distance cargo transportation: long distance cargo transportation, long turnover time, good heat dissipation of German axle, more high temperature resistance, low fuel consumption, small tire damage, lighter weight than American axle and longer maintenance cycle. It is suitable for long-distance transportation.

(2) Cold chain transportation / express and express cargo transportation: this kind of goods have higher requirements for transportation timeliness and higher requirements for vehicle stability and reliability. German axle generally has long maintenance cycle and better stability and reliability.

4. Three wire six axle axle

Large cargo transportation / large cargo transportation: the three-line six axle axle axle is specially customized for large cargo transportation vehicles, with a large number of tires, reducing the average pressure on the contact surface and reducing the damage to tires and roads.

5. Low flat axle

(1) Transportation of low flat Trailer: the low flat axle is specially designed for low flat trailer, with lower height, which is convenient for goods to get on and off, and for vehicles to pass through the height limited road section, with higher transportation stability.

(2) Vehicle transport semi-trailer: vehicle transport semi-trailer generally has the characteristics of stable lifting, safe and convenient operation, smooth driving, etc. The low flat axle has lower center of gravity, strong stability and good bearing capacity, which can meet the transportation needs of vehicle transportation semi-trailer.
