- Typical heavy‑duty suspension, suitable for trucks, buses, construction machinery and trailers.
- Uniform stress distribution, excellent resistance to impact, vibration and lateral forces.
- Maintains stable support even under overloading or heavy‑load conditions.
3. Low Cost & High Cost‑performance
- Raw material, manufacturing and assembly costs are much lower than air suspension and coil springs.
- Low initial investment and low maintenance cost.
- Ideal for economic, engineering and commercial vehicles.
4. Easy Maintenance & Replacement
- Simple and intuitive structure for easy repair.
- Fast replacement without special sites or equipment.
- High versatility of parts with sufficient market supply.
5. Integrated Guiding Function, No Extra Guide Mechanism Required
- Leaf spring acts as both elastic component and guiding mechanism.
- Withstands longitudinal and lateral forces, simplifying the chassis structure.
- Reduces components such as tie rods and swing arms, making the whole vehicle more compact.
6. Adaptable to Harsh Environments
- Resistant to dust, mud, sand, high temperature and severe cold.
- Performs excellently in mines, construction sites, rural roads and unpaved surfaces.
- Unlike air suspension, it is not vulnerable to puncture, freezing or blockage.
7. Long Service Life
- Mature materials with high fatigue strength.
- Can achieve hundreds of thousands of kilometers without major overhaul under normal use.
8. Wide Range of Applicable Vehicles
- Heavy trucks, light trucks, mini trucks, buses, trailers, construction machinery, agricultural vehicles and RVs.
- Mature solutions available from light‑duty to super heavy‑duty applications.
