Product Description: Factory Direct High-Strength Parabolic Leaf Spring for SHACMAN Heavy Duty Trucks
Product Overview
This high-strength parabolic leaf spring is engineered specifically for SHACMAN (Shaanxi Heavy Duty Truck) series, including X3000, F3000, and M3000 models. As a factory-direct supplier, we provide OEM-standard suspension components designed for extreme load-bearing capacity and durability in mining, construction, and long-haul logistics applications. The parabolic leaf design offers a superior balance between weight reduction and fatigue resistance, ensuring optimal performance under maximum payload conditions.
Technical Specifications & Design Features
-
Structural Design: Utilizes a tapered parabolic leaf configuration (typically 2-4 leaves) with variable cross-sections. This design reduces inter-leaf friction by up to 70% compared to traditional multi-leaf springs, resulting in smoother ride quality and extended service life.
-
Material Composition: Manufactured from high-grade alloy steel (60Si2Mn , 55CrMnA), which undergoes precise quenching and tempering heat treatment. This process achieves a hardness of HRC 42-50 and a tensile strength exceeding 1300 MPa, ensuring resistance to permanent set and sagging.
-
Surface Protection: Features a multi-stage anti-corrosion system including shot peening (to induce compressive stress and enhance fatigue life) followed by electrophoretic epoxy coating (E-coating). This provides over 500 hours of salt spray resistance, critical for harsh operating environments.
-
Load Capacity: Engineered to support axle loads from 8 to 16 tons, with specific configurations available for tipper trucks, tractors, and mixer chassis. The parabolic geometry allows for progressive spring rates, maintaining stability under both laden and unladen conditions.
Manufacturing & Quality Assurance
Our production facility operates under IATF 16949 quality standards with full vertical integration from steel sourcing to final assembly. Each batch undergoes rigorous testing including:
-
Fatigue Testing: Minimum 1 million cycles under dynamic load simulation.
-
Static Load Verification: Deflection and load capacity testing to ensure compliance with SHACMAN OEM specifications.
-
Dimensional Inspection: Precise verification of camber, eye diameter, and center bolt alignment for direct bolt-on replacement.
Commercial Advantages
-
Factory Direct Pricing: Eliminating intermediary margins allows for highly competitive pricing, with further discounts available for container quantity orders.
-
Customization Support: We offer flexible OEM/ODM services, including custom arching, bushing material selection (rubber or polyurethane), and packaging (bulk or retail).
