Heavy truck cab becomes the last barrier to passive safety

The safety of the medium and heavy truck cabs is of utmost importance. As the last barrier to passive safety, a sturdy and safe cab can often save drivers and drivers from danger. From the perspective of safety, the safety of medium and heavy trucks is divided into active safety and passive safety. The safety of the cab is an important part of passive safety. Illegal operation and bad weather are the main causes of accidents, but the basic causes of major casualties are related to the level of automobile manufacturing in China.

Some analysts believe that there are outstanding problems in the structure of cars produced in China, and the gap in safety performance between Europe and the United States is still very large. The existence of this problem makes the cab unable to withstand strong impact. Once a violent collision occurs, it is difficult for the driver to escape in time. The lesson of blood has given Chinese car manufacturers a wake-up call. Europe has very strict standards for car safety certification. The heavy-duty cab has a widely used keel structure with high safety performance, which is worth learning in China. Some experts called for the reference to European standards to quickly formulate China's heavy truck safety regulations.

High standard achievement safety cab

Europe is the most developed area in the automotive industry, and its requirements for vehicle safety performance are also very high. In Europe, a strict vehicle safety certification system is implemented. Only cars that pass safety certification and comply with automobile safety regulations are allowed to be produced, sold, imported, and used. At present, among the 99 laws and regulations of the European general-purpose ECE regulations and standards system, there are 81 security regulations and standards, of which 55 are active security and 26 are passive security. Through multi-level vehicles, the safety performance is hard to pick and the safety of occupants is extremely good. ECE regulations emphasize the harmonization, applicability and operability of regulations and standards and are adopted by more and more countries.

It seems that in establishing a system of automobile safety regulations and standards, China should learn from Europe. Insiders point out this point: If China completely accepts the European automobile safety system, whether it is the manufacturer’s cost of production or the user’s unacceptable consumer affordability, the national conditions still do not allow this, but we can Learn from people's advanced concepts, combined with their own reality, starting with some aspects. For example, European heavy-duty trucks generally adopt a keel type cab structure, which has low cost and light weight, high strength, and safety performance that meets and exceeds ECE R29. This is a realistic and feasible model worthy of China's heavy-duty learning. The situation shows that the keel-type cab has become the standard for domestic heavy-duty trucks.

In addition, experts call on the country to quickly formulate relevant laws and regulations, especially safety regulations, to establish standards for the sustainable development of the truck manufacturing industry. Establishing safety standards can draw lessons from the experience of establishing emission standards, drawing on European automotive safety standards, and formulating relevant laws and regulations in light of national conditions. This is a matter of course. The key is that the state should pay attention to it and effectively implement China's truck safety regulations as soon as possible to regulate the truck industry and provide guidelines for its healthy development. This is in line with the fundamental interests of the people, because the truck industry is an indispensable part of the automobile industry.

Domestic safer cab

In the early days, domestic flat-truck cab technology came from Mitsubishi and Nissan Diesel, as well as Steyr. The safety performance of these cabs was slightly inferior. At present, several flat-head cabs with a high domestic safety factor are: Beiben V3, Auman H4 from Mercedes-Benz body technology, Dongfeng Liuzhou Bolong 507 and Renlong 609 from Renault technology, new from Iveco technology Hongyanjieshi, from China National Heavy Duty Truck HOWO and other truck cabs from Volvo cab. The body of these cabs adopts a keel type structure, which has better rigidity and hardness, and is less deformed when impacted by external forces, giving the occupants a space to survive. Therefore, although the cost is higher, for the sake of safety, these European flat cabs will also be popularized in the future.

At the same time, Liuzhou's Longka, the Liberated J5R, and Dongfeng's Longhead Dragon Head and other American-style long head heavy trucks also provide relatively good passive safety, which may also be a development direction. Truck drivers live on the car all year round. The cab is not only their living space, but also their safe protection cabin. While improving the performance of domestic heavy-duty trucks, safety should not be overlooked. It should be synchronized with engine power, transmission gear, and rear axle torque capacity. Lightweight, high-efficiency, economical, and safe should be associated, and they must not be unilaterally pursuing speed and efficiency. Because there is no security, everything cannot be discussed; safe transportation is the cornerstone of everything in the logistics industry.
