Why are car owners reluctant to use center axle road trains?

The central axle trailer is a rising star among freight vehicles. GB1589 relaxes the outline size of the central axle trailer compared with the semi-trailer, and introduces the central axle road train at the same time.

Central axle road train is a kind of car train, which is composed of automobiles and central axle trailers. It can be mainly divided into heavy truck + central axle carriage, light truck + central axle carriage, passenger car + central axle carriage, and central axle Several types of vehicles, transport vehicles, etc.

The center-axle road train has one more carriage than the ordinary trailer, and it is said that the maximum transportation volume can reach about 120 square meters, which is equivalent to the compliance loading capacity of two traditional 9.6-meter trucks; secondly, the center-axle road train has a lower center of gravity, Under the same turning radius, the center-axle train can be made longer; in addition, it can also be used as a single vehicle, which can be used alone as the main vehicle or towed to the carriage. The tow is flexible and is very suitable for The advantages of express delivery, less-than-truckload and light dump cargo transportation, especially in special line transportation, are more obvious.

Looking at the freight market in recent years, the center-axle road train has been unknown in other fields except that it has emerged in the field of sedan transportation. Since it can load more cargo and be registered on the road in compliance with regulations, why has it not been popularized? ? The main reasons are as follows:

1. Switching in a short period of time requires more investment

At present, the vehicles running on the road are mainly traditional semi-trailers, and the illegal use of large-deck vehicles has not been cured. In terms of transportation, although the central axle road trains will be slightly better than semi-trailers, but in the face of There is no advantage when the board is large. Besides, replacing vehicles with central axle road trains in a short period of time needs to invest a lot of money, which is not advantageous from the perspective of users.

2. Road conditions and station design are not suitable for center axle road trains

At present, many domestic logistics companies, parking lots, and roads are designed according to semi-trailer and other models. The center-axle road train appeared late and failed to catch up with the Red Sea in the initial logistics development. Its model features are obvious. The design requirements for road conditions and stations are also relatively high. Therefore, the central axle road train may only be used as a vehicle in a small number of scenarios.

3. The technology of central axle road trains in China is not mature

Many car owners have reported that the center axle road trains have poor stability when driving on wet and slippery roads, and are prone to tail flicking when the road is slippery in rainy days. In addition, in some road sections with large drop, center-axle road trains tend to tail up when going uphill, and the driving wheels are prone to slipping, which makes the vehicle unable to move forward. Besides, when the center axle is running, the body is easy to swing up and down or left and right, and the movement of the rear trailer is more flexible. If the speed is too fast, it is easy to cause tail flicking. In severe cases, it may even cause the vehicle to lose control and roll.

4. Other models with mature technology have virtually suppressed the development of center-axle road trains

At present, the domestic medium and long-distance transportation market is still dominated by semi-trailers. No matter in terms of loading capacity, carrying capacity, and applicable working conditions, semi-trailers can meet the transportation needs of most goods. The most important thing is that the semi-trailer market is relatively mature, and the types are relatively rich, and its status in the world may not be shaken in a short time.

Although this is still the case at present, we must also see that center-axle trains have long been popular and mature products abroad. The modularization and standardization of international and domestic transportation markets are a major development trend. With the continuous development of vehicle technology, center-axle Vehicles may be used by group companies more in the future, and their market coverage may also be improved to a certain extent.

No matter what kind of transport model, it also needs to be equipped with high-quality trailer axles in order to play a better role in the transport field. DARO Group is one of the first companies in China to mass-produce "one-piece" trailer axles. It has been focusing on the research and development and manufacturing of trailer axles for 20 years. Axles, RV axles, agricultural trailer axles, special trailer axles, etc., can provide customized services according to customer requirements, helping car owners reduce comprehensive vehicle costs and achieve energy saving and emission reduction.
