Over the years, the user’s high expectation of economic efficiency for transport vehicles has made “overloading†a common phenomenon and a persistent disease. What’s worse is that this trend has been guiding or forcing manufacturers to continuously improve the carrying capacity of vehicles. Adapt to their needs. Trailers (especially semi-trailers) are the main delivery vehicles for road transport. "Overloading" has become its main selling point. Whose car does not have "overload" or "overload" capability is not strong, who has no market for cars, and a series of semi-trailer trains that wriggle on the road like small trains can explain the problem. The product design ideas of many trailer companies are not considering how to improve the technical performance and level of products (such as safety, economics, etc.), but consider how to meet the increasing users of raw materials and components. Overload demand. As a result, the trailer has been continuously strengthened and strengthened: the frame, suspension, axle, etc. The safety factor has reached a fairly high level. For example, some car bottom plates actually use 5 mm thick steel plates. Various means are used to provide a very large space for “overloadâ€. The harm of “overload†is obvious and well-known. It has accelerated the damage to vehicles, reduced the service life of roads and bridges, and caused continuous traffic accidents, causing serious casualties and economic losses. In response to the phenomenon of "overloading", the relevant state departments have also taken many measures. However, because of many reasons such as out-of-government administration and chaotic management, the phenomenon of "overloading" has not been effectively suppressed. Since the second half of 2003, in order to fundamentally eliminate "overload," the state has stepped up efforts to crack down on "overloading," and has gradually moved forward in the right direction in accordance with the law. First, the "Law of the People's Republic of China on Road Traffic Safety", which was implemented on May 1, 2004, explicitly listed "overloading" as an illegal act for the first time, and penalized the "overloaded" behavior more severely than ever before. "Overloading" provides a strong legal basis. Secondly, the mandatory standards “Outline size, axle load and quality limits for road vehicles†(hereinafter referred to as the “Standardsâ€) jointly drafted by the National Development and Reform Commission, the Ministry of Public Security, and the Ministry of Communications will be issued in the second half of 2004. The strict limits on the external dimensions and axle load of the semi-trailer are aimed at regulating the manufacture of transport vehicles and minimizing the possibility of “overload†at the source. This also provides a clear definition for “overloadâ€. Technical Support. Third, the "fuel tax" reforms that are in demand will also play an active role in governing "overloading." These measures will bring about an extremely important chain reaction to purify the market environment and regulate the production of enterprises. In the future, we can no longer "overload". Then what products should we devote to the earning users? This is a question that manufacturers should answer as soon as possible. Through the study of relevant national policies and standards and the analysis of the trailer market, the author believes that trailer manufacturers should adjust product development strategies as soon as possible, and change the development of trailer products from “overloaded†to “specialized†and “efficientâ€. And strive to improve the technical level of the product. The increase in the degree of specialization in the development of transportation vehicles for products to “dedicated†will promote the improvement of transportation efficiency and transportation quality. In the seventies and eighties of the 20th century, in many developed countries, the amount of special vehicles refitted from the chassis of the trucks accounted for about 50% of the total vehicle load. A closer look at the world of cars will reveal that the special car market is indeed a big, tempting cake. In the United States, known as the "car kingdom," the special-purpose vehicle market not only feeds many modified car companies we have not heard of, but their profit margins are so high that car giants are envious of them. The sustained growth of China's special-purpose vehicle market is accompanied by the rapid development of economic construction and the implementation of active fiscal policies. In the next few years, the demand for special vehicles in the Chinese market will be more diversified, and the products will be developed in the direction of heavy-duty, special-purpose functions, and high-tech content. However, the development of dedicated trailers, especially heavy-duty trailers, lags behind. The "Standard" has many strict restrictions on the slat type semi-trailer, but the size of the van, tank, and container type special trailers has been relaxed. The purpose is to encourage the development of special trailers; and some trailer companies have formed flexible production methods. It is also very suitable for the characteristics of special trailers with multiple varieties and small batches: Therefore, all enterprises should seize the opportunity to develop special trailer products on the basis of earnest investigations, find their own market position and market space as soon as possible, and grab the first in the special trailer market. machine. The shift from designing to “efficiency†users to buy a car is to make money. Naturally, the shorter the time it takes to recover costs, the better, and the more profits they earn, the better. In the past, with the "overload" capability of the trailer to increase the transportation volume of the single-lift truck to increase the transportation efficiency, it cannot be "overloaded" (the maximum total mass of the vehicle and the axle load will be limited). The design concept of the trailer should be changed from "overloaded" to "overloaded". Efficiency type "change. In the design, reasonable selection of raw materials shall be adopted to optimize the safety factor of the frame, suspension, axle and other assembly to a reasonable level so as to reduce the consumption of raw materials and the vehicle's service quality, and correspondingly increase the vehicle load quality. It means that the quality utilization factor of the trailer is improved, and the high reliability of the trailer is ensured by increasing the technical strength and manufacturing level of the enterprise and the strict control of the purchased parts, so that the design and manufacturing of the trailer can reach a higher level. In this way, through the refinement of design and manufacturing, the trailer is of stable quality, reliable performance, reduced maintenance times, reduced maintenance costs, and extended service life, enabling the vehicle to maintain a highly efficient working condition at all times, thereby creating continuous wealth for the user. Even if it is not "overloaded", users will be able to obtain a reasonable return with the vehicle's high efficiency and even earn more than "overload." Technological progress is an eternal theme. Increasing the technical content of trailer products is also an important aspect of trailer product development strategies. Since the reform and opening up, the technical level of cars and trucks in China has been significantly improved, but there have been no major technological advances in addition to the application of various valves in the brake system. With the rapid growth of China's economy, road transport is playing an increasingly important role. The modern logistics industry is increasingly demanding transportation tools. The transportation companies only have good quality vehicles (such as imported tractors. More and more, in order to gain the favor of the shippers in the competition, and contract to high-demand, high-profit, high-end market businesses, the trailer manufacturers must work hard to improve the technical level of the products. 1. ABS GB “Structure, Performance and Test Method of Automotive Braking System†issued on October 1, 1999 stipulates: Since January 1st, 2003, O4 trailers must be equipped with anti-lock braking devices ( ABS). The role of ABS is to avoid wheel lock during braking, effectively shorten the braking distance, and improve the handling of braking, which can effectively reduce traffic accidents. According to relevant experts, although the mandatory regulations have already been implemented, so far, heavy-duty trucks are rarely equipped with ABS, and almost no trailers have been installed. Enterprises are still on the waiting list, and they are not even technically sound. Preparation. The new products that now apply for the "Announcement" must carry ABS. This may also be one of the reasons why the new product trailers declared in recent batches are much less than before. Products that have been on the "Announcement" may not be installed for the time being, but after the one-year delay period (that is, on October 1, 2004), O. Trailers must be equipped with ABS, so trailer manufacturers should be prepared as soon as possible. When the time comes, the government will really be more serious than the real ones. 2. Air Suspension Air Suspension is based on the compressibility of air. The air enclosed in the airbag is used as an elastic element. Different system pressures are used to balance different loads so that the vehicle maintains its height regardless of whether it is empty or full. Can meet the higher requirements for vehicle handling stability, smoothness, safety and other aspects. In foreign countries, air suspension systems have been widely used in both passenger cars and trucks; air suspension has only been applied in recent years in China, and it is currently only applied to luxury passenger cars. As for the trailer industry, it is just starting. (Home-made tractors use it to be late), but applying air suspension to trailers that transport hazardous chemicals, precision instruments, household appliances, and other goods that require a high level of transport conditions will become a trend, and this also means that The future technological development trend of China's transport vehicles. The soon-to-be-promulgated "Standard" will increase the axle load quality limit for vehicles equipped with an air suspension system by more than 15% compared to the axle load quality limit for vehicles equipped with a leaf spring suspension system, enabling a better economy for vehicle operations. The benefits also indicate that the government encourages technological progress. The box-mounted semi-trailer mounted on the air suspension produced by the Zhangjiakou Trailer General Plant has gained a certain advantage in the competition of the high-end cargo transportation market with its excellent performance. In addition, in the design of trailers, we must actively follow many other advanced technologies from abroad, such as vigorously adopting new materials and new technologies such as high-strength steels, aluminum alloys, and glass and steel, improving the functions of special devices, and continuously improving the dynamic and economical performance of vehicles. And reliability, to create greater benefits for users. In short, in the historical period when the current policy environment and market environment are undergoing major changes, the trailer manufacturers must assess the situation and adjust the product development strategy as soon as possible so that enterprises can survive and continue to grow in the fierce market competition.
