The next five development trends of the trailer

As the main force of domestic cargo transport, semi-trailer is the most familiar model of car owners, and the future development trend of semi-trailer directly affects the efficiency of road transport. In the future, what will be the development trend of the semi-trailer?

● Trend 1: lightweight, more cargo loading

With the development of the country's vehicle overloading activities, the current long-distance semi-trailer basically belongs to the standard load transport. Under the premise that the total limit value is unchanged, how to reduce the weight of the vehicle has become the most concerned problem. The lightweight of semi-trailer is once again valued by everyone.

Semi-trailer weight reduction, the car factory is also trying to do a variety of ways, such as many trailer plants use lighter weight aluminum alloy materials to manufacture semi-trailers. Traditional steel semitrailers use stronger steel to trailer axle further reduce the weight of the vehicle by making special-shaped holes in the girder.

In order to reduce self-weight, the use of large single tires with aluminum alloy wheels is also a big development trend. Compared with the traditional twin, it can reduce a certain weight, load more goods, and improve the vehicle operation income. At the same time, the large single tire has a smaller contact area with the ground than the twin tire, low resistance, and can also have better fuel economy.

● Trend two: Intelligent, semi-trailer will be more and more intelligent

Intelligence is now mentioned more words, before the high technology in the tractor is now also applied to the semi-trailer. For example, the tire pressure monitoring technology can realize the automatic monitoring of the tire pressure of the semi-trailer, find that there is an abnormal tire pressure, and the system can timely notify the driver of the vehicle, repair the semi-trailer tires, ensure transportation safety and improve transportation efficiency.

In addition, now the domestic semi-trailer began to be equipped with automatic charging and deflating system, to the pressure of the tire timely charging and deflating, so that the tire pressure is always at the normal pressure value, reduce the chance of blowout, increase the service life of the tire.

It is understood that in the semi-trailer disc brakes, some German companies have designed a brake with brake disc wear alarm sensor, when the brake disc wear to the warning position, the sensor can timely feedback the information to the driver, thereby improving driving safety.

● Trend three: compliance, disc brake air bags will be popular

The strict implementation of the regulation of car transport and over-limit transport management regulations, the future of semi-trailer transport will be more standardized, those ultra-long and ultra-wide semi-trailers will become history in the near future, and the future semi-trailer will be more compliant.

In addition to the profile size of the semi-trailer, the load is more compliant, and the chassis configuration is also more standardized. According to the new regulation GB7258, since January 1, 2020, the three-axis fence plate and warehouse grid semi-trailer must be equipped with disc brakes, and the dangerous goods transport vehicle will use the disc brake one year in advance. The new regulations give car companies and truck drivers two years as a buffer, it can be seen that the trailer chassis accessories will be more compliant in the future.

In addition, GB7258 also stipulates that air bag suspension will be used in future models such as three-axis fence plate and warehouse grid semi-trailer. The use of air bag suspension on the semi-trailer can make the shock absorption effect of the vehicle better, and the vehicle can improve the trailer axle when the vehicle is unloaded, reduce the friction between the tire and the ground, reduce the vehicle fuel consumption, and improve the fuel economy.

● Trend four: High efficiency, longer maintenance mileage of semi-trailer

Nowadays, China's logistics has been rapid development, whether logistics companies or individual retail investors, the annual mileage of trucks are increasing, it is normal to run 150,000 kilometers a year, for some of the vehicles of the trunk logistics company, the mileage is often longer to reach more than 300,000 kilometers.

At present, most of the ordinary axle maintenance 100,000 kilometers once, like the special line logistics runs 300,000 kilometers a year, and the axle head is maintained 3 times a year, which not only delays the operation efficiency of the vehicle, but also distracts the energy of the user. The use of long maintenance axle allows more attention to be paid to the operation of the vehicle. For example, the BPW 400K axle can achieve 400,000 km long maintenance of the axle head, and such a long maintenance axle can better improve the operational efficiency of the semi-trailer. In the future, the semi-trailer will become more efficient, and the improvement of axle maintenance mileage will become the focus.

It is worth mentioning that the high efficiency of the semi-trailer in the future is not limited to the long maintenance of the axle. For example, the hub power generation axle developed by BPW, after the axle is equipped with a hub power generation system, it can output electrical energy during driving and braking, and its electricity can supply the use of refrigerated semi-trailer transport vehicles. For example, the trailer axle solar panel on the semi-trailer to generate electricity, the use of these technologies will also make the semi-trailer more efficient and energy-saving.

● Trend five: Specialization, semi-trailer special car will be inevitable

In the past quite a long period of time, many semi-trailers pulled with their own operating conditions do not want to match the goods on the road for transport, which not only disrupted the market order, but also there are greater security risks. For example, ordinary plate trailers pull some liquid goods transported by tank trucks, and some fence semi-trailers buy quilts to pull frozen goods, which is likely to cause the thawing of goods and affect the quality of goods.

With the stricter national regulations and the improvement of people's awareness of production safety, more and more attention is paid to semi-trailer special vehicles. For example, box-type semi-trailers pull light dumping and express delivery, while refrigerated trucks transport frozen products and vegetables. Special car is more conducive to the healthy development of the logistics industry, so the future development trailer axle of semi-trailer will be specialized.

The restrictions of regulations and the needs of the market determine the future development direction of the semi-trailer. In the future, the semi-trailer will develop in the direction of lightweight, intelligent, compliant, efficient and professional. This is related to reducing the cost of use of users, related to the vital interests of users, the semi-trailer factory is also sparing no effort to research and development and improvement in these directions, in order to produce better products to meet the needs of users, and promote the efficient development of domestic materials.
