The maintenance-free, long-life heavy-duty truck universal joint has pioneered a systematic set of technologies—including dual-profile compensation seals and vibration-absorbing mechanisms—that enable the joint to operate throughout its entire service life without maintenance or replacement, achieving exceptionally long mileage. This product has been recognized as the first domestically produced (set) of its kind. The lightweight, high-strength, and highly efficient commercial vehicle universal joint has broken through key technological barriers in structural matching design, sealing, low-friction vibration absorption, and other areas; its technical level is internationally advanced, and it has received Zhejiang Province’s first recognition for such a product. The intermediate telescopic light-duty truck aluminum alloy drive shaft features an all-aluminum, ultra-lightweight design, incorporating a novel aluminum-material intermediate sliding and telescoping sub-structure, and has been awarded Zhejiang Province’s Outstanding Industrial Product designation.

The development of constant-velocity drive shafts featuring low vibration, large angular displacement, and high efficiency has incorporated technologies such as an integrated ball-ring needle roller bearing angular-contact sliding joint, a large-angular-displacement fixed joint, and press-fit force management. This breakthrough has broken the foreign monopoly, placing the overall technology level domestically leading and internationally advanced, and has earned the province of Zhejiang’s first-of-its-kind equipment certification. The end-face-driven low-torque hub bearing unit boasts domestically leading overall technology, while its end-face spline tooth profile error measurement and evaluation technology is internationally advanced, also earning Zhejiang Province’s first-of-its-kind equipment certification. The key technology research project on new-energy vehicle chassis suspension assemblies has achieved lightweight design, platformization, and versatility through optimizing product structure and adopting technologies such as hydraulic forming. The resulting products feature internationally advanced technology and have been awarded the First Prize for Science and Technology in Mechanical Industry by Zhejiang Province.
