Lightweight, High-Strength, and High-Efficiency Commercial Vehicle Universal Joint

Recently, the Zhejiang Provincial Department of Economy and Information Technology released the list of Zhejiang Province’s first-of-its-kind (set) equipment for 2023, and Wanxiang Qianchao’s “Lightweight, High-Strength, High-Efficiency Commercial Vehicle Universal Joint” project was included on the list. This marks Wanxiang’s third independently developed first-of-its-kind (set) product to receive such recognition, following its “Low-Vibration, Large-Angle, High-Efficiency Constant Velocity Drive Shaft Product” in 2020 and its “1 Million Kilometers Maintenance-Free, Long-Life Heavy-Duty Truck Universal Joint” in 2021.

“First-of-its-kind equipment” is an abbreviation for “first-of-its-kind major technical equipment.” It refers to the first or initial batch of equipment products that have been innovatively developed, featuring significant breakthroughs in variety, specifications, or technical parameters, and possessing intellectual property rights. Such equipment exhibits outstanding characteristics, including breakthroughs in high technology, the ability to drive industrial development, and substantial market potential. It serves as an important indicator for measuring a company’s core competitiveness and reflecting the high-quality development level of the manufacturing sector.

Wanxiang Qianchao is dedicated to the research and development and manufacturing of automotive components, and provides systematic and collaborative solutions for the modularization of automotive parts. The company boasts independent R&D capabilities, core manufacturing technologies, and comprehensive testing and inspection facilities. Its universal joints and wheel hub units are globally leading and rank first in China's industry; its products such as drive shafts, constant-velocity joints, and bearings are also domestically leading. Wanxiang Qianchao is a national demonstration enterprise for intellectual property rights, as well as a provincial-level smart factory and green factory.

Lightweight, High-Strength, and High-Efficiency Commercial Vehicle Universal Joint

The universal joint cross-shaft assembly is a key core component for commercial vehicles. With the rapid development of modern logistics and the global demand for energy conservation and environmental protection, universal joint drive shaft assemblies for commercial vehicles are rapidly evolving toward technologies such as lightweight design, high load capacity, high efficiency, green practices, and extended service life. Wanxiang Qianchao boasts a complete industrial chain for universal joint drive shaft systems and is both a demonstration enterprise championing single-item excellence in automotive universal joint assemblies and a demonstration enterprise championing single-item excellence in drive shaft products. Guided by the strategic goals of “lightweight, compact, minimal, and long-lasting” as well as “extremization, ultimate refinement, and sophistication,” Wanxiang Qianchao has achieved systematic innovation and breakthroughs in universal joints, enabling it to enter mainstream global markets. Its technology for “high-strength, lightweight, and highly efficient commercial vehicle universal joints” significantly surpasses that of domestic peers, filling a technological gap in the field of lightweight, high-strength, and high-efficiency commercial vehicles. This technology is leading the development of the domestic industry, achieving import substitution and driving the universal joint drive shaft assemblies toward lightweight designs and higher transmission efficiency. It plays a crucial role in promoting the development of China’s automotive industry and also lays a foundational basis for commercial vehicles to achieve intelligent advancements—such as ultra-long mileage and autonomous driving—on the basis of green practices and high efficiency.

1 Million Kilometers Maintenance-Free, Long-Life Heavy-Duty Truck Universal Joint

The maintenance-free, long-life technology for heavy-duty universal joints has always been the core of heavy-duty drive shaft assemblies. The R&D team at Wanxiang Qianchao has achieved self-innovation in technology, independently developing highly reliable sealing structures—particularly in the lightweighting of cross shafts—and making breakthroughs in technologies such as bearing lubrication systems and new material development. This has filled a domestic technological gap in maintenance-free, long-life universal joints for heavy-duty trucks, resolving the critical "bottleneck" issue surrounding key core components for heavy commercial vehicles. The product’s overall performance has reached international advanced levels, enabling import substitution and significantly enhancing the international competitiveness of domestic brands. The product is now being mass-applied to high-end flagship models of leading domestic automakers and will gradually be promoted to European and American markets in the future. The application of this product greatly reduces resource consumption, energy use, and waste emissions, allowing end customers to achieve maintenance- and replacement-free operation throughout the entire lifecycle of the drivetrain—a quintessential example of green component manufacturing under the “dual-carbon strategy.” Recently, the Provincial Department of Economy and Information Technology announced the list of 2023 Zhejiang Province’s first-of-its-kind equipment application incentive projects, and Wanxiang Qianchao’s “1-million-kilometer maintenance-free, long-life heavy-duty truck universal joint” project was selected.

Low-vibration, large-angle swing, high-efficiency constant-velocity drive shaft products

With the advancement of modern automotive technologies, especially the promotion of the “New Four Modernizations” (electrification, intelligence, connectivity, and sharing), traditional constant-velocity drive shafts are increasingly unable to meet the new demands of automotive development. There is an urgent need for a shift toward lower vibration (improved NVH performance), lightweight design, miniaturization, higher torque capacity, and greater efficiency. Wanxiang Qianchao’s constant-velocity drive shaft plant regards low-vibration, large-angle-rotation, and high-efficiency constant-velocity drive shaft products as top priorities for development. These products can effectively enhance the vehicle’s fuel economy and provide drivers with a superior driving experience.
