The steering knuckle is a core safety casting in the vehicle chassis and steering system, undertaking three key functions: oad-bearing, force transmission, and steering. It directly determines vehicle handling precision, driving stability, and operational safety. Our factory specializes in the R&D and large-scale production of mechanial castings. Utilizing mature casting processes and precision machining, we provide high-strength, high-reliability, and long-life steering knuckle castings for commercial vehicles, construction maery, and new energy vehicles.
I. Core Functions of the Product
Bear the body weight and road impact loads, suitable for heavy-duty, bumpy, and continuous operation conditions Transering torque to ensure precise steering, zero play, and stable self-centering Connect the wheel, suspension, brake, and steering mechanism to achieve stable steering and safe braking
1. High-quality Material Selection, Reliable Strength Adopts ductile iron / alloy cast irn (QT450-10, QT500-7, QT600-3, etc.), featuring high tensile strength, good toughness, fatigue resistance, and impact resistance, meeting the requts for heavy-duty and complex operating conditions. 2. Mature Casting Process, Dense Internal Structure Resin sand / green sand molding ensures dimensional stability and minimal deformation
Rational pouring andon treatment ensure no shrinkage cavities, porosity, or cracks Full-process quality control ensures metallurgical structure and mechanical properties meet standards 3. Precision Machining,ree Assembly High-precision machining of key holes, shaft necks, and mounting surfaces
Strict control of geometric tolerances ensures tight fit and uniform clearance during assembly Supportd structures such as ABS/sensor mounting positions and brake bracket mounting surfaces 4. Stable Durability, Safety Assurance Verified through fatigue testing, bench testing, and road testingnds millions of load cycles without cracking or deformation, providing fundamental support for vehicle safety.
III. Application Scenarios
Commercial vehicles: Heavy-duty trucks, light-duty trucks, busConstruction machinery: Loaders, excavators, road rollers, mining vehicles New energy vehicles: New energy heavy-duty trucks, electric buses, special purpose vehicles Export models OEM supply, and aftermarket
