What kind of axle is suitable for common eight transportation conditions?

The axle is one of the very important parts on the semi-trailer, which belongs to the core of the vehicle driving mechanism. It is not only directly related to the strength of the load bearing performance of the vehicle, but also plays a role in alleviating the impact of the road surface, ensuring the braking effect and maintaining the vehicle running.

With the continuous development of the automobile market, there are more and more trailer axle brands on the market. So, how much does a brand new trailer axle cost?

This problem needs to be analyzed in detail. Like other goods, trailer axles also have differences in brand, technology, process and so on. Taking 13t drum axle as an example, most of its current prices are concentrated between 3000-4500 yuan, and high-end products can float to about 6000-8000 yuan, of course, there are some little-known small factories whose prices can be reduced to about 2000-2500 yuan. In addition, the model, configuration, quantity and other factors selected by the owner will also have more or less an impact on the final transaction price.

It is worth noting that price is not the only factor in the purchase of trailer axles. Take the production process as an example, although the trailer axle for the production technology and technical level of the requirements are very high, but all this can not be identified by the naked eye from the appearance, even if the manufacturer cut corners to shoddy, the owner is still difficult to distinguish before use. Therefore, it is necessary to take into account the brand, qualifications, reputation, etc., if conditions permit, you can also visit the factory site.

In addition, it is also necessary to consider their own transportation conditions. Common transportation conditions can be divided into the following eight types:

1, regional bulk grocery delivery (short distance, light load, standard load)

2, port transport (short distance, fast, shake off)

3, logistics express transportation (long-distance, efficient, punctual)

4, green transportation (long distance, efficient, on time)

5, cold chain transportation (long distance, efficient, on time)

6, sand and gravel transportation (composite section, full load)

7. Transportation of hazardous chemicals (composite section)

8, Yunguichuan area special delivery (composite section)

Next, let's simply analyze what kinds of configurations are suitable for these working conditions:

1. Regional bulk grocery delivery:

Short-distance transportation standards are the same day or the next day, basically in the province or the city, most of the goods are loaded, will not exceed the legal limit. Distribution road conditions are mainly national and provincial roads, supplemented by high speed. Under this condition, as long as the car is not legally forced to use the disc brake, the choice of axle is still relatively free.

2. Port transportation:

Port transport has high timeliness requirements, and often a tractor can play the work efficiency of two or even three tractors. This kind of transportation condition has higher requirements for vehicle attendance and longer requirements for axle maintenance interval, which is suitable for choosing maintenance-free axle. In addition, the German axle has low fuel consumption, small tire damage, light weight and long maintenance cycle, which can also be considered.

3, logistics express transport/green transport/cold chain transport:

These three working conditions have certain similarities, such as long-distance, efficient, punctual, requiring the goods to reach the destination within the specified distance and time, and the requirements for cargo damage are more strict. The owner can choose a maintenance-free axle or a German axle with good stability and a long maintenance period, or a disc axle with a more stable brake output (medium and heavy semi-suspension requires the installation of liquid slow auxiliary braking), and the use of air suspension.

4. Transportation of sand and stone:

There are many composite sections in this kind of transportation conditions, and the bearing capacity of the axle is required to be higher. In contrast, the requirements for shock absorption and cargo loss rate are small. You can choose the American drum axle, "one-piece" axle beam resistance to heavy load is stronger, with ordinary steel suspension can be.

5. Transportation of hazardous chemicals:

The transportation of hazardous chemicals has not high timeliness requirements, but the safety of the car itself and the operating skills of the driver are extremely high, which can be said to be contained in the mouth and held in the hand. In such conditions, it is recommended to choose a disc axle to reduce the accident caused by the uneven distribution of braking force and slow heat dissipation of the brake as much as possible. With liquid to relieve air suspension, improve safety performance.

6, Yunguichuan region special delivery:

The road conditions in the Yunguichuan area are also very typical, which used to be basically the golden partner of drum axle + shower cooling, and now you can continue to choose this combination.

However, with the development of vehicle technology, the combination of disc axle + hydraulic retarder is becoming more and more common, the vehicle weight is lighter, and the safety is higher, which can not only make the vehicle stop smoothly within a shorter distance, but also extend the service life of the friction plate, reduce tire loss, fully save energy and consumption, and save the comprehensive cost of the vehicle.
