Comparative Overview: Major Leaf Spring Technical Metrics
Applications & Use Cases
The 5 leaf spring forms the backbone of heavy-duty vehicle suspension for trucks, agricultural equipment, and trailers. Its modular build provides an optimal balance between ride comfort and load-bearing. Meanwhile, advanced solutions such as the 28 leaf spring target extreme-load vehicles (mining trucks, specialty trailers), and the double leaf spring is favored in articulated chassis for superior damping and stability.
- Passenger Vehicles: Improved comfort and durability.
- Commercial Trucks: Supports payloads from 1.2T–5T per axle, handles rugged terrain.
- Trailers & Agricultural Vehicles: Tailored flex profiles to reduce fatigue and extend operational lifespan.
- Specialty Vehicles (e.g., tankers, mining dump trucks): Customizable high-leaf-count assemblies for extreme demands.
Material Science & Technological Innovations
Leaf springs today leverage alloys such as SUP9 and 60Si2Mn, boasting superior fatigue resistance and customized stress distribution. Innovations include:
- Shot Peening: For up to 30% greater fatigue life (Springer Professional)
- Finite Element Analysis (FEA): Reduces design-to-market time and optimizes geometry for weight savings
- Composite Leaf Springs: Provide up to 50% weight reduction vs. steel (MDPI Materials)
- High-Performance Coatings: Phosphate, epoxy, or zinc layers for corrosion protection exceeding 500 hours in salt spray tests
