Zonxin Heavy-Duty Beam-Type Air Suspension Successfully Passes Qualification Review

On July 28, 2026, Tai’an Aerospace Special Vehicle Co., Ltd. organized a qualification review meeting for Zonxin’s beam-type heavy-duty air suspension system at Zonxin’s facility. Experts in vehicle engineering and representatives from aerospace vehicle manufacturers gathered to conduct a comprehensive evaluation. After detailed verification, technical discussions, and expert assessments, the review committee unanimously confirmed that the product meets all development standards and successfully passed the qualification review.

The Liangshan County Government attached great importance to this review. Sun Yantao, Deputy County Mayor in charge of science and technology, Qin Tao, Director of the County Science and Technology Bureau, and Wang Xinggang, Deputy Director, visited Zonxin in advance to supervise and guide the preparation work for the meeting.

The expert panel consisted of leading professionals in the field, including Professor Chen Xiaokai from the School of Mechanical Engineering and Vehicle Engineering of Beijing Institute of Technology (Deputy Director of the National Engineering Research Center for Electric Vehicles and Secretary-General of the Suspension Technology Branch of the China Society of Automotive Engineers), Researcher Hou Youshan from China North Vehicle Research Institute, Professor-level Senior Engineer Zhang Mico from China Highway Vehicle & Machinery Co., Ltd., and Researcher Yang Xianxue from the 15th Institute of China Aerospace Science and Technology Corporation (CASC First Academy).

During the review, the expert team conducted an in-depth inspection of Zonxin’s manufacturing processes, carefully listened to the project team’s technical report, reviewed the complete set of technical documentation, and carried out extensive discussions focusing on product performance, process reliability, and manufacturing consistency. Following a comprehensive evaluation, the review committee unanimously concluded that the 2900100L/R Beam-Type Heavy-Duty Air Suspension complies with all qualification requirements and officially approved the product’s status qualification.

As a domestic manufacturer specializing in vehicle chassis suspension systems, Zonxin has always regarded independent research and development as the core driver of innovation. The company continues to increase investment in high-end chassis components and has established an integrated development system covering R&D, prototype manufacturing, testing, and mass production.

For many years, key technologies and components of 2900100L/R beam-type heavy-duty air suspension systems have relied heavily on imports, creating challenges for the development and security of the equipment supply chain. Focusing on technological independence and domestic substitution, Zonxin established a dedicated R&D team to overcome technical barriers, insisting on independent design, development, and manufacturing of core components, and accelerating the localization of heavy-duty beam-type air suspension technology.

Through continuous innovation, Zonxin’s engineering team has successfully addressed multiple technical challenges, including suspension load-bearing capacity, fatigue resistance, and adaptability to complex operating conditions. The company has continuously optimized structural design and manufacturing processes to ensure that product performance meets relevant industry standards.

In the future, Zonxin will continue to focus on the development of core vehicle chassis components, strengthen cooperation with aerospace special vehicle manufacturers, universities, and research institutions, and contribute to the advancement of high-end equipment manufacturing.
