The hottest energy saving and emission reduction p

Energy conservation and emission reduction have led to the application of new materials in trucks

in recent years ③ high gloss black effect. With the acceleration of highway networking and the development of logistics and transportation industry in China, the market demand for heavy trucks has increased. In 2011, there were 5million heavy trucks in China. In view of the prominent problems of heavy truck overload, fuel consumption, pollution and so on, the state has raised the weight charging and fuel standards of freight vehicles, and increased the research and development of new lightweight materials for heavy truck bodies.

the application of composite materials in heavy trucks

in the late 1980s, due to the continuous improvement of the awareness of automobile energy conservation and environmental protection in various countries, the requirements for automobiles have increased. They should have the characteristics of low energy consumption, safety and reliability, strong mobility and high speed. Heavy truck is an important tool of modern transportation. Because composite materials have the characteristics of light weight, low manufacturing cost and high integration of parts, they are applied in the field of heavy truck and have great potential

composites have the properties of light weight, high strength, convenient processing and molding, excellent elasticity, chemical corrosion resistance and weather resistance, which can improve the use function of materials, and have been widely used in all kinds of trucks. With the continuous improvement of people's awareness of environmental protection and the introduction of environmental protection laws and regulations in various countries, how to make trucks meet the requirements of environmental protection has attracted more and more attention. As one of the main development directions of truck materials in the future, composites will play a very important role. For example, the high-tech composite materials jointly developed by Baotou Deyi, Beijing Bluestar and Sinoma science and technology have been successfully applied in the domestic truck carriage for the first time. The lightweight of the carriage has been reduced by 40%. The manufacturing cost of carbon fiber pultrusion profile is low, the strength is high, and the quality is stable. It is a typical application of composite materials in the field of automobile lightweight in China

application of aluminum alloy in trucks

due to the 40% increase in the price of aluminum alloy glass, it has a series of excellent characteristics, such as low density, light weight, high strength, good elasticity, good impact resistance, corrosion resistance, easy surface coloring, good processing formability and high recycling and regeneration. A large number of aluminum alloys are used in automobile manufacturing to reduce the total mass of automobiles, thereby reducing fuel consumption and reducing exhaust emissions. An all aluminum semi-trailer can reduce the weight by 3.4 tons, save 45000 liters of fuel and reduce 110 tons of carbon dioxide emissions within its life cycle

relying on the group's complete industrial chain and national technology research and development platform from raw aluminum and aluminum deep processing to aluminum end products, Shengtong automobile company has achieved 93% Aluminization rate of semi-trailer body without reducing the stiffness of the whole vehicle by using large-scale aluminum alloy complex cross-section sections and combining the optimization design means of CAE calculation and analysis. The light opening of the whole vehicle announced many products comparable to foreign models Some experiments have been protected by national appearance patents, and the quantification has reached the international advanced level, realizing 34% light weight of the car body, with outstanding energy-saving effect. Through the research of fuel-saving technology to reduce wind resistance, the fuel consumption per 100 kilometers has been reduced by 2.15l

as customers have higher and higher requirements for energy conservation, emission reduction and vehicle safety, automobile manufacturers have to seek stronger and lighter vehicle building materials. Through the transformation of automobile structure and the optimization of manufacturing materials, the application of new materials in trucks will be more full and practical
