Are the axles and the axle the same part? How to choose the trailer axle?

In daily life, we often see the term "axle" and "axle assembly" in some news or advertisements, and sometimes we will listen to some owners mention it. We know that these components are the necessities of the vehicle, it seems to be installed on the chassis of the vehicle, the role seems to be very different, but it is not clear if you go into detail.

In fact, the "axle" and "axle assembly" look only one word difference, it sounds like the same item, and even some encyclopedia platforms will confuse it. But in fact, the two are not the same thing. Next, we will tell you a brief popularization.

Generally speaking, the components of commercial vehicles can be divided into four categories, namely: engine, electrical equipment, body and chassis. The most complex is the chassis, which is divided into four systems: transmission, driving, steering and braking.

Among them, the driveline is a power transmission system, that is, the power of the engine is transmitted to the wheels to drive the vehicle; The driving system is a weight-bearing system that enables the vehicle to carry heavy loads. The steering system and the brake system are the systems that control the vehicle, and the driver can operate the vehicle through these two systems. What we call "axle assembly", "axle", "suspension" and "frame" basically belong to the driving system.

The axle, in general, refers to the half-shaft, which is an shaft between the main reducer and the drive wheel, mainly used for force transmission, and is the main part of the axle assembly.

Axle assembly, the main role is to carry the load, through the suspension and the frame is connected, both ends can be installed wheels, it can also be understood as the axle assembly, that is, including axle, brake, suspension.

After the vehicle is loaded with goods, the direct force component is the frame, commonly known as "girder", the frame through the suspension, the pressure is transmitted to the axle assembly, and finally dispersed to the wheels.

Axle assembly is the key component of the vehicle chassis, which is related to the safety and benefit of the vehicle. In the selection of axle assembly, in addition to the vehicle tonnage, vehicle model and other hard factors, what other aspects need to pay special attention to?

Raw materials. The driving conditions of commercial vehicles are harsh and changeable, and the axle assembly must bear the load changes such as loading, uphill and downhill, but also bear the impact brought by potholes and water. Only the quality of raw materials passes, the finished products of the axle assembly produced can fully meet the standards in strength.

Production process and technology. The production of axle assembly is not a simple processing and manufacturing, from the beginning of raw materials to the final product assembly to go through at least a dozen production processes, the more advanced the process, the more the accuracy, stability, corrosion resistance, and safety of the axle assembly can be guaranteed.

In terms of weight. On the one hand, the load-bearing capacity of the axle assembly, and on the other hand, the weight of the axle assembly itself. Load-bearing is not much to say, as the main load-bearing parts of the vehicle, good bearing capacity is the necessary performance of the axle assembly. However, how to reduce the weight of the axle assembly itself while achieving super bearing capacity requires technology. After the axle assembly weight reduction, not only can give the user more transportation space, but also reduce fuel, energy saving and efficiency.

Darong Machinery Co., Ltd. is the representative of the old trailer axle in China, and also the leader in the northern trailer axle market. It is the first high-tech enterprise to enter the special automobile industry base in China.

In terms of raw materials, Darong trailer axle adopts 20Mn2 high-strength alloy seamless steel pipe, which enhances bending and torsional resistance; The workshop is equipped with the industry's leading automated intelligent production line and the latest international quality testing instruments. The process of one-piece heat treatment molding, integral axle casting, powder spraying + electrophoresis, 3D forging molding and other mature processes produce trailer axles with higher precision, stronger stability, more durable and longer maintenance cycle; The advantages of self-weight are obvious, compared with traditional products to reduce 10%-20%, surface rust resistance and corrosion resistance to increase 90% to improve transportation efficiency and reduce operating costs.
