What is the development trend of lightweight commercial vehicles?

1. Lightweight is to reduce the weight of each component as much as possible under the premise of ensuring the comprehensive performance indexes of the whole vehicle, such as strength, safety and reliability, and comprehensively considering the triangular factors of "quality, performance and price". By reducing the self-weight of commercial vehicles, fuel consumption can be reduced, thus reducing the emission of harmful substances, saving weighing costs, improving the utilization coefficient of load quality and increasing transportation profits. At present, the domestic demand for truck transportation is mainly logistics transportation and engineering construction: the demand for heavy trucks mainly based on infrastructure construction is gradually decreasing; The demand for commercial vehicles based on logistics and transportation is increasing; At the same time, with the continuous improvement of "Dora Run" by local regulatory authorities and the strengthening of highway law enforcement, the advantages of light commercial vehicles have gradually become prominent.

2. From the customer's point of view, lightweight has become the general trend. Customers demand higher and higher freight efficiency, and the demand for compliant light commercial vehicles is also increasing. Lightweight enables commercial vehicles to load more goods in compliance. While ensuring road traffic safety, it can not only greatly improve the fuel economy, but also improve the transportation efficiency of the logistics industry. Practitioners' pursuit of lightweight is gradually moving from blindness to rationality. Therefore, vehicle manufacturers need to develop new lightweight commercial vehicles on the basis of meeting the original market demand.

3. To realize the lightweight of commercial vehicles, materials, technologies and structures are indispensable. The key is how to solve the durability problem after lightweight. Clearly understand the performance of various materials, and carry out targeted lightweight design for materials with different strengths under different working conditions. The lighter the weight, the better. For example, express logistics vehicles are usually standard, with large volume, light weight and relatively single goods. Highway-based road conditions are better. This market segment model is more suitable for lightweight design.

4. For a long time, overloading phenomena such as "Dora overload" are common on domestic roads. Long-term overload will seriously affect vehicle safety, reduce normal braking performance, increase braking distance, and lead to an increase in traffic accident rate. Since 20 16, local regulatory authorities have concentrated on overload control, reducing the original load limit of freight cars with more than 6 axles from 55 tons to 49 tons. Traffic accidents were reduced in that year, and safety hazards were also reduced to a certain extent. On the basis of satisfying the whole vehicle design, increase the bearing space of commercial vehicles as much as possible to improve the market competitiveness of vehicles. In terms of carrying space, commercial vehicles are mainly used for cargo transportation. As long as the appearance conforms to the relevant specifications, the larger the bearing space, the stronger the performance.

5. In short, the lightweight of commercial vehicles is further expanded and upgraded from the aspects of design, manufacturing technology and application of new materials, so as to realize the integration of lightweight technology. As a kind of automobile, commercial vehicle is closely related to people's daily life. Lightweight will help to build a low-carbon and environmentally-friendly life.
