Pneumatic disc brake assembly developed successfully

China's automobile brake components have made great strides in localization

A pneumatic disc brake assembly, which is closely related to the safety of automobile driving but has long been subject to foreign core technology and seriously affects the localization process of China's automobile industry, has been successfully developed by Jiangsu Hengli Brake Manufacturing Co., Ltd. It has been listed as a high-tech product by Jiangsu Province. Recently, this important achievement with many independent intellectual property rights and core technologies has been declared by Jiangsu Province as the key project of the 2006 National Torch Program.

The pneumatic disc brake assembly introduces the international advanced design concept of digestion, and adopts the pneumatic double-pushing disc double-adjusting braking technology to automatically automate the excessive clearance caused by the friction of the friction plate and the brake disc friction component of the automobile brake system. Alarms, automatic adjustments, and automatic compensation are implemented to encourage high-speed vehicles to pass through sensitive, fast, and effective emergency braking, and to respond to various emergencies, greatly reducing and avoiding accidents in the operation of automobiles.

This innovative product has been tested and confirmed by the National Automobile Quality Supervision and Inspection Center. Its various technical indicators and performances have reached or exceeded the domestic similar product standards, and can completely replace imports. At present, many luxury bus manufacturers and heavy truck factories in China have listed this innovative product as a stereotyped accessory product and widely promoted it.

For a long time, most of the various types of automobile brake devices in China have applied conventional drum brake assemblies. Due to the outdated structure, the brake device clearance adjustment system is still manually adjusted according to the driver's feeling, resulting in defects such as partial brakes, heat generation, decay, excessive noise, and frequent maintenance due to brake lag, which brings significant impact to the running vehicle. Hidden accidents.

Jiangsu Hengli Brake Manufacturing Co., Ltd. is one of the national key enterprises engaged in the development of automobile brakes and automobile steering devices. Its leading products all kinds of brake assemblies have formed an annual production capacity of 500,000 sets, and become more than 30 famous automakers such as FAW Group, Dongfeng Group, Jianghuai Group, Beiqi Foton and Ankai, Yutong, Jinlong, Iveco and North Benz. 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, more than 70% of multinational auto parts giants have turned their eyes to the Chinese market with the import tariffs of automobiles increasing year by year. The parts and components industry has experienced unprecedented fierce competition in the past 10 years. In the meantime, the constant force brakes are aimed at the domestic and international automobile market, and quickly adjust the existing product production portfolio; the second is to vigorously carry out the internal product quality and service quality rectification, consolidate and develop the old product application field; the third is to rapidly increase new products and new The development of technology, efforts to develop new complementary products with high technology content and large market capacity. Therefore, the pneumatic disc brakes with domestic leading level and completely replace imported products have been developed in the same year, put on the market in the same year, and formed benefits in the same year.

Xu Qichen believes that the production base of China's auto parts is very weak. More than 90% of domestic parts manufacturing plants have small production scale, low management level, poor development capability and lack of market competitiveness. Improve the industrialization rate of domestic auto parts and gradually form an export advantage. We must implement key research and breakthrough innovations for key components that affect the performance and quality of automobiles. We must explore the core technologies with independent intellectual property rights and develop practical products with international leading level. Sex products can make domestic cars in an invincible position in the fierce market competition.

The internal structural design is vane, Vane Damper is  more suitable for soft close. ABD vane dampers are used to dampen drives, control speed, and many other applications. The damping direction of the vane dampers with continuous rotation can be clockwise, counter clockwise, or in both directions. Vane dampers are widely used in automobile interior decoration, household electric appliances, furniture and bathroom products, etc. Our dampers can make the movement of structures soft, quiet and safe to mitigate the impact, avoid the damage, increase the mechanical life, reduce noise, and improve product quality.
