Sponsored by China Automotive Engineering Society, China Institute of Internal Combustion Engines, Chongqing Association of Science and Technology, Chongqing Automobile Engineering Association, SAIC Iveco Hongyan Commercial Vehicle Co., Ltd. supported the "Second China Commercial Vehicle Development Summit Forum" held in Chongqing. The theme of this forum is "Energy conservation, environmental protection and technology, social responsibility and mission." Experts and scholars from the automotive industry delivered speeches on energy-saving emission reduction and current hot issues.
Play a positive role of foreign capital
Zhang Xiaoji, Chairman of the China Association of Automotive Engineers, said in his speech: “Commercial vehicle companies are facing increasingly severe challenges. With the implementation of the National III emission standards, the continuous rise in raw material prices will inevitably lead to increased production costs for enterprises. The dual pressures of rising prices and overall decline in sales. Discussing the issue of energy-saving and emission reduction for commercial vehicles here shows that commercial vehicle companies have a strong sense of social responsibility and mission.â€
Zhang Xiaoyu cited such a set of data to illustrate the competitive advantages of China's commercial vehicles. He said that in the field of commercial vehicles in China, self-developed enterprises have become the dominant force. Ranked in the top 10 companies in the production and sales charts, the products accounted for 88% of the market share. In China's commercial vehicle market, 80% of trucks, 90% of passenger cars and special vehicles are independent brands. Based on me, integrated innovation has become the main choice for the internationalization of technology for commercial vehicle companies. The introduction of key assembly technologies and independent management of market development have become the dominant form of business development. In 2007, China exported 610,000 cars. Among them, heavy trucks and large and medium-sized passenger vehicles accounted for 55% of total exports. Commercial vehicles have become the main force for China’s auto industry to participate in international competition.
Zhang Xiaolu believes that in the new situation, the use of foreign capital and technology import is still a necessary way for the development of commercial vehicles. Therefore, the active role of foreign capital in promoting independent innovation, industrial upgrading, and regional coordination should be brought into full play. He particularly emphasized that we must clearly understand the difficulties encountered in current production and operations, take active measures to tide over the difficulties, fully implement the 11th Five-Year Plan of industrial policies, and unswervingly achieve the goal of energy-saving and emission reduction, and realize the goal of becoming a manufacturing industry by 2020. Strong country's strategic goals. The development of special vehicles and special vehicles should attract the attention of the whole industry, and it is necessary to deeply understand and grasp the national conditions that frequently occur in natural disasters, and to more effectively improve disaster prevention and reduction capabilities.
Take the initiative to meet market challenges
Xu Changming, director of the Economic Information Center of the State Information Center, explained the necessity of energy conservation and emission reduction for trucks from the relationship between the development of national economy and the upgrading of trucks. He said that the development of commercial vehicles is inseparable from the good environment of the national economy. Before 2020, the demand for commercial vehicles in China will still maintain a growth rate that is roughly equivalent to the growth rate of GDP, and the high-end trend of commercial vehicles will become increasingly apparent. He believes that both the central and local governments have positive policies and will be implemented better. Energy-saving and emission-reduction is a policy that both the central and local governments have enthusiasm for, and implementation will be more thorough. Commercial vehicle companies must strengthen their sense of competition, prepare for industry trends and corporate reality, and actively meet the market challenges brought about by the upgrading of emission standards.
Guo Konghui, an academician of the Chinese Academy of Engineering, gave a speech titled "Automotive Independent Brands Faced with Severe Challenges." He analyzed the status quo of China's auto industry, the problems and causes of the development of auto brands, enumerated different models for auto companies to develop their own brands, and proposed that commercial vehicle companies must face the difficulty of brand building and pay attention to the cultivation of innovative talents. He pointed out that the government should increase policy support and encourage enterprises to carry out independent innovation, continuously enhance the vitality of enterprises, and promote the vigorous development of the automobile industry.
Keep up with the pace of development
Liu Wei, deputy chief engineer of China National Heavy Duty Truck and director of the technical center, focused on the development of EGR technology. He said that in the process of upgrading the emission standards, CNHTC has adopted an unconventional technology route, namely, electronically controlled inline pumps and exhaust gas recirculation technology. When CNHTC adopts this technology, there are two considerations. One is that the development of high pressure common rail technology requires core technology, and to obtain the core technology mastered by the foreign party, it will pay a high price and a long period of time. Can rely on their own strength. Another consideration is the desire to develop talents through independent development. Otherwise, the gap with the world's advanced level will grow. Practice has proved that the independently developed EGR technology works well. When talking about development experience, Liu Wei said that he very much agrees with the opinions of experts attending the meeting on self-development, that is, the first must be done on their own, the second must be done seriously, the third must be persisted, and the fourth must be open and autonomous. Development.
Deputy General Engineer of Shaanxi Heavy Duty Truck and Deputy Director of Automotive Engineering Research Institute Li Tianzhou said that Shaanxi Automobile State III heavy truck assembly uses Weichai engine with high pressure common rail technology. In 2005, it began to be installed on the vehicle to perform matching and reliability tests. Last year, Shaanxi Auto made full preparations for production in accordance with the schedule of implementation of the National III standard in January 2008. After the product was put on the market, better results were achieved. Now we have started the complete vehicle matching test of the National IV emission standard engine. Shaanxi Auto must keep pace with the development of the times in the practice of energy saving and emission reduction.
The steering knuckle can be divided into left and right steering knuckles according to the assembly position. The upper and lower ears of the left steering knuckle have one each
The taper holes are respectively used to install the upper arm and lower arm of the steering knuckle, while the right steering knuckle has only one hole to install the lower arm in the lower ear
Taper hole.
