An air-pressure disc brake assembly that is closely related to the safety of motor vehicles but has long been subject to foreign core technologies and has seriously affected the domestic production process of the automobile industry in China has recently been successfully developed by Jiangsu Hengli Brake Manufacturing Co., Ltd. And was listed as high-tech products in Jiangsu Province. Recently, this important achievement with a number of independent intellectual property rights and core technologies was declared by Jiangsu Province as a key project of the 2006 National Torch Plan.
Pneumatic disc brake assembly introduces internationally advanced design concept. It adopts pneumatic dual push-plate double-adjustment braking technology to automatically perform excessive clearance caused by abrasion of the friction component and brake disc friction component of the automobile brake system. Alarms, automatic adjustments, and automatic compensation are implemented to prompt high-speed vehicles to pass through sensitive, fast, and effective emergency braking, to respond to various emergencies, and to greatly reduce and avoid potential accidents in automotive operations. This innovative product has been tested and verified by the National Automobile Quality Supervision and Inspection Center. Many of its technical indicators and performances meet or exceed the standards of similar domestic products and can completely replace imports. At present, many domestic luxury passenger car plants and heavy truck plants have listed this innovative product as a stereotyped accessory product and widely promoted and applied it.
For a long time, most types of automobile brake devices in our country have applied the traditional drum brake assembly. Due to the obsolete structure, the brake system clearance adjustment system still depends on the driver's feeling and manual adjustment, resulting in brake lag due to brakes, fever, recession, excessive noise, frequent maintenance and other defects, to the running of the vehicle Hidden accident.
Jiangsu Hengli Brake Manufacturing Co., Ltd. is one of the key state-owned enterprises engaged in the development of automotive brakes and automobile steering devices. Its leading products of various types of brake assemblies have an annual capacity of 500,000 sets, and have become more than 30 famous ones such as FAW Group, Dongfeng Group, Jiangzhun Group, Beiqi Foton, and Ankai, Zitong, Jinlong, Iveco and North Benz. Depot supplier.
Xu Qichen, chairman and general manager of Hengli Brake Manufacturing Co., told reporters that over the past five years since China's accession to the WTO, as auto import tariffs have been reduced year by year, more than 70% of transnational auto parts giants have turned their sights to the Chinese market, leading to the 2005 automobile industry in China. The spare parts industry has witnessed an unprecedented fierce competition in the past 10 years. During this period, Hengli Brake aims at the foreign automobile market and rapidly modulates the existing production mix. Second, it vigorously carries out internal product quality and service quality rectification, consolidates and develops old product application areas; third, it rapidly increases new products and new products. With the development of technology, efforts are made to develop new types of complementary products with high technological content and large market capacity. Therefore, the air-pressure disc brakes that have the leading domestic level and can completely replace imported products have achieved development in the current year, put on the market in the current year, and formed profits in the year.
Xu Qilu believes that the production base of China's auto parts is very weak. More than 90% of domestic parts and components manufacturers have small production scale, low management level, poor development capability and lack of market competitiveness. To increase the industrialization rate of domestic auto parts and gradually form an export advantage, we must carry out key research and breakthrough innovations for key components that affect the performance and quality of automobiles, and must dare to explore core technologies with independent intellectual property rights and develop practically internationally advanced technologies. Sex products can make domestic cars stand invincible in the fierce market competition.
In the 1980s, the matching rate of air-pressure disc brakes in the luxury passenger car market in Europe reached over 90%, and the matching rate in the field of trucks and large trailers reached more than 70%. Due to the international blockade, the braking devices of all types of passenger cars and trucks in China still use the traditional drum structure. A few automakers have to import foreign patented disc brake devices to increase their reputation.
In order to quickly adapt the braking system of domestically-made vehicles to international standards, Hengli Brake has introduced talents from science and technology and implemented technical cooperation with well-known domestic and foreign companies such as the School of Automobile and Traffic Engineering of Jiangsu University and Nanjing Iveco Axle Factory to introduce the foundation of German technology concept. At the same time, extensive technological innovations were carried out. They carried out joint research on the technology and materials of brake discs, clutches, adjusting screws and other key components of the automatic brake control and automatic adjustment mechanism, developed multi-screw axial positioning devices, built-in angle sensing intelligent devices, and brake linings. The innovative results such as the automatic wear and tear of brake discs, automatic alarms for brake discs, automatic adjustment devices, and effective suppression of the noise caused by friction pairs and the emission of pollutants. Its key technologies such as self-adjusting mechanism for braking gap, double-disc double-regulating device, caliper pneumatic device and other key technologies applied for 6 invention patents and new technology patents, making this new type of braking device a leading level in domestic leading-edge technologies.
The expert test and practical application show that the device has large braking torque, good heat dissipation performance, and small effect of thermal recession. The braking performance is about 25% higher than the domestic similar products, and the product cost is only two-thirds that of similar imported products. According to the calculation of the national automobile authority, this year, the country’s domestic demand for this product is about 200,000 sets. If we increase investment and rapidly increase the production capacity of this product, the annual sales of this new type of brake device can reach RMB 1 billion. Save foreign exchange up to 2 billion yuan.
