The transfer case chain of four-wheel drive vehicles requires characteristics such as reliability, quietness, high speed, and lightweight. Only a few chain companies in the world can provide this type of chain.

In the past few years, Evergrande has closely cooperated with well-known domestic automobile manufacturers to successfully develop a series of high torque, long center distance, high-speed, and lightweight transfer case chains, and has multiple technical patents.

The off-road vehicle transfer case chains of Evergrande Group are made of high-grade high-quality alloy steel materials, and the chain plates are formed by precision extrusion technology and treated by isothermal quenching technology to obtain high hardness, strength, and impact toughness. The surface of the pin shaft is treated with ultra-high hardening, which has good wear resistance. According to the theory of chain meshing, the formed chain plate teeth and sprocket achieve perfect meshing, which not only demonstrates durability and reliability, but also adapts to long-term high-speed operation, and performs excellently in product lightweighting and low noise.

In addition, for working conditions that require extremely high wear performance, Evergreen Group can provide a dual pin (2-Pin) structure toothed chain, which is an innovative chain product. The relative rotation between chain links is changed from sliding friction between the pin and the chain plate to rolling friction between the pin, and its wear resistance is several times that of traditional single pin structure toothed chains.
