Trailer axle lightweight and high bearing which is important?

With the continuous improvement of the development level of logistics and transportation industry and the continuous improvement of relevant regulations, owners of trailer axle production technology is increasingly high requirements, many brands are committed to their own axle to create a unique selling point, such as lightweight, maintenance-free, high bearing labels are endless.

Today, we will focus on the analysis of the main lightweight trailer axle, and the main high bearing axle, which is more practical.

1. Lightweight axle: lighter dead weight.

Lightweight, is a term emerging in recent years, or can also be said to be a development trend in the trailer industry. To some extent, reducing axle weight can help save fuel, reduce vehicle costs and improve operation efficiency.

For example, disc trailer axle, with exposed brake disc instead of 360° wrapped brake drum, naturally lighter weight, if with lightweight materials and accessories, optimize the internal structure design and manufacturing process, its weight advantage is more obvious.

German axle, for example, is also a representative type of lightweight axle, especially the special structural design of the shaft head and the "three-piece" welding treatment of the shaft beam, so that it is generally superior to other axles in saving fuel and reducing tire damage.

It is worth noting that the axle lightweight must be built on the basis of safety. In order to pursue product lightweight, some bad manufacturers blindly reduce the thickness and strength of raw materials, or change the product design and structure at will, which is not desirable. Owners need to polish their eyes when buying.

2, high bearing: more robust and resistant.

Although many lightweight axles on the market can take into account load-bearing while realizing lightweight, many owners, especially those who often transport heavy cargo owners, are still more inclined to those who use enough material and more solid axles when consulting.

For example, the most widely covered type of axle in the domestic market - American trailer axle, its most prominent feature is good heavy load performance, which is its "one-piece" shaft casting technology, and higher thickness, shape rule of the shaft head design.

Another example is low flat axle, as a typical heavy-duty vehicle special axle, its shaft beam in wall thickness is much larger than other axle types, high strength bearing is not easy to crack or deformation.

Another example of heavy distribution special axle - three - line six axle axle, its maximum bearing capacity can reach 80t or so, which requires the shaft beam and even accessories must be made of special materials with higher thickness and strength.

But correspondingly, these trailer axles are less dominant in the lightweight field.

As for the question of which is more practical, the "honey of one and arsenic of the other" depends on whether it meets their own needs.

Different types of trailer axles suitable for transport vehicles:

1. Disc axle

(1) Three-axle fence plate/warehouse grid vehicle: according to GB7258-2017 standard, three-axle fence plate and warehouse grid type semi-trailer belongs to the model with mandatory disc axle installation, compliance with which will affect its registration or driving on the road.

(2) Precision instruments/valuables transportation: due to the particularity of the transportation of goods, the transportation requirements are also relatively strict. Disc axle brake sensitive and more stable, can avoid the transport of goods in the process of bump or large vibration.

(3) Transportation of dangerous goods: hazardous chemical transport vehicles have higher risk factor than ordinary cargo vehicles. The use of disc axle can reduce and avoid accidents caused by uneven distribution of braking force and slow heat dissipation of brake as much as possible.

2. American axle

(1) general goods transportation: American axle selling price is relatively low, accessories industry common, simple design, replacement and maintenance is more convenient, can be widely used in all kinds of general goods transportation.

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

3. German trailer axle

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

(2) Cold chain transportation/express and express cargo transportation: This kind of cargo has higher requirements for timeliness of transportation and higher requirements for stability and reliability of the car. German axle generally has a long maintenance cycle and better stability and reliability.

4. Three-line six-axle axle

Bulky transport/jumbo transport: three-line six-axle axle is specially customized for bulky transport vehicles, with a large number of tires, reducing the average pressure of contact surface and reducing damage to tires and road surface.

5. Low flat axle

(1) Low plate trailer transport: low plate axle is specially designed for low plate trailer, which is shorter in height, convenient for loading and unloading of goods, and convenient for vehicles to pass through the height limit section, with higher transport stability.

(2) Vehicle transport semi-trailer: vehicle transport semi-trailer generally has the characteristics of smooth lifting, safe and convenient operation, smooth running and so on. Low flat axle center of gravity is lower, strong stability, good bearing capacity, can meet the transportation needs of vehicle transport semi-trailer.
