The most attractive place for the biennial IAA is the trend of the exhibition to lead the development of global commercial vehicles. The 62nd IAA, which ended on 2 October, brought this feature to the extreme. Efficient, energy-saving and simple become the main theme of this exhibition.
Compared with previous exhibitions, the products exhibited in this exhibition have taken a big step forward in terms of quantity, innovation, industrialization speed, and leading the future development trend. Wisman, chairman of the German Automobile Industry Association, commented: "This show shows that global commercial vehicles are moving in the direction of energy saving, high technology and high efficiency."
New concept and new technology support
The reporters felt the deepest of this year's show is the electronic, hydraulic, electrical integration technology used in a large number of commercial vehicles. The application of these product technologies brings the most significant changes to the vehicle. It is more efficient, energy-efficient and simple.
Wang Xinyu, deputy head of the body department of FAW Technology Center, told reporters that the truck body exhibited at this exhibition did not change much, mainly due to the lower floor of the cab, which resulted in a larger cab space and more spacious personnel. In contrast, the biggest change is in the application of electronic technology on the cab, making operation easier.
The reporter saw that the hydraulic system has been widely used in the special vehicles exhibited at this exhibition. At the exhibition, many light commercial vehicles equipped with automatic loading and unloading of goods, such as hydraulic tailgates, small forklifts (Figure 1), the core of these systems is the hydraulic system. Some vans have their tails simply removed from the cargo platform (Figures 2 and 3). The hydraulic system can be used to automatically lift and unload containers. The car is equipped with slides and hoisting systems that also allow the loading and unloading of cargo. More convenient. These ingenious designs around the hydraulic system, the greatest effect is to reduce the loading and unloading links, so that the operation of cargo handling is simple and efficient.
Jost is the largest manufacturer of hydraulic legs and traction seats in Europe. At this exhibition, the KKS system introduced by the company enables the driver to complete all the operations such as hanging, unhooking, and supporting the legs in the cab. The fully automatic safety pedestal launched by this company not only saves more than ten minutes of manual operation, but also makes the operation process more secure.
BW, the largest manufacturer of axles in Europe, has launched a brand new axle system (ECOEDISE) at this exhibition. This system integrates axles, suspensions and EBS to reduce weight and make maintenance easier and more convenient.
Accelerate the pace of marketization of innovation results
The product technology exhibited by IAA is mainly divided into two parts, namely the more advanced technology and the technology needed in the current market. The former has a larger proportion, while the latter only accounts for a small part of the exhibition. To the surprise of the reporter, many new products and technologies that were exhibited in the last exhibition have become mainstream products on the market two years later.
At the last exhibition, the Phoenix series box-type semi-trailer launched by Cogell was often seen on European highways. The Phoenix series of box-type semi-trailers exhibited at this year's show has been further improved in terms of light weight, such as the materials of the front and gooseneck parts of the carriage, which have been changed from the previous steel plate and aluminum plate to carbon fiber. . The thickness of the gooseneck part was reduced from 90mm to 50mm, and two new technologies reduced the body weight by about 1 ton.
Smith Company, Europe's largest manufacturer of box-type semi-trailers, has exhibited the scalable container technology for shipping containers during the previous exhibition. This year, it has been applied in the market. This technology enables the vehicles to flexibly load containers of different sizes and weights through the telescoping skeleton, reflecting the multi-functional trend.
In addition to the beam used for welding, the semi-trailer frame that was made by riveting was used in other parts of the exhibition. The debut of the semi-trailer at the previous exhibition caused a stir. Today, the degree of marketization of this technology is already quite high. In addition, the carbon steel dump trucks, which were more commonly seen in the last exhibition, were replaced by aluminum alloys and white steel. Tank trucks made of stainless steel and aluminum alloy, as well as the tailgate that can double as the back door of the carriage, have also become the mainstream products in this exhibition.
Chinese companies benefit
The European commercial vehicles that have been “accumulated†with a large number of new technologies, high-grade materials and advanced manufacturing processes are far from the commercial vehicle market in China. “For the US and Japan markets, many of the products here are expensive.†An expert from a specialist car industry in China evaluated the exhibits at the show.
Even so, many insiders in the industry still reflect the benefits. At this exhibition, the multimodal transport system representing the future development of logistics and transport was concerned by Dr. Xie Liangfu, director of the CIMC Technology Center. He has studied this for many years. He believes that it is of great significance to promote multimodal transport systems in China.
In this exhibition, some of the world's top parts and components companies, such as Yost, BPW, WABCO, and other companies, have introduced systematic integrated products, representing the direction of the development of special vehicle components. In fact, domestic companies have encountered similar problems in the development process.
A component company that supports vans has very low added value. For many years, it can only be sold to the European market at a slightly higher price than raw materials. Recently, in the course of exploring the domestic market, there were more than 20 types of parts and components related to their products. By visiting this exhibition, the sales staff of this company realized that only by integrating these 20 kinds of parts together can they more easily knock on the door of van companies.
The riveted frame is very common at this exhibition, which is a small revolution for the trailer company. The frame can be riveted, meaning that the frame can be assembled and the production area can be changed from centralized production to decentralized production. Smith has already begun to shift the frames produced by its German factories to Eastern European countries, where it produces low-cost parts and then assembles them in various markets, which greatly reduces the cost. Smith's approach allows the production of transport vehicles to approach the production of trucks. This is a project that CIMC focuses on. If such a production method can be implemented at home, it will greatly reduce production costs and the impact on the market will be profound.
