Steering knuckle is the key part of vehicle steering system, and its mechanical properties and surface qualities are very strict. The current production technologies of branch-like steering knuckle are obsolete, which become the restriction of increasing productivity and improving the quality. Aiming at Jetta steering knuckle, the technology of two forging steps in one heat is presented. This technology is mainly composed of a closed die extrusion with the extrusion belt and open finish-forging. Experimental researches and numerical analysis show that the new technology is feasible and the mechanical property of the forging piece can be improved.
