| Component Name | Rear Multi-Leaf Spring Assembly (Heavy-Duty Mining Grade) |
| Axle Position | Rear Suspension – Load Support & Articulation |
| Vehicle Type | Off-Highway Mine Dump Trucks / Wide-Body Articulated Haulers |
| Typical Models | Tonly TL875, TL855; LGMG MT86, MT95; XCMG XGA Series |
| Number of Leaves | 14 or 15 pieces (high-strength variable cross-section design) |
| Leaf Thickness | 25 mm – 30 mm |
| Leaf Width | 100 mm – 120 mm |
| Main Material | 60Si2Mn or 50CrV High-Performance Spring Steel |
| Heat Treatment | Quenched and Tempered (Q&T) for enhanced strength and fatigue life |
| Weight (per unit) | 380 kg – 450 kg (ultra-heavy-duty class) |
| Function | Supports rear axle load, absorbs road shocks, maintains alignment under full load |
| Parameter | Value / Detail |
|---|---|
| Yield Strength | ≥ 1,200 MPa |
| Tensile Strength | 1,400 – 1,600 MPa |
| Fatigue Life (Simulated Duty Cycle) | >150,000 cycles under dynamic loading (mining profile) |
| Elastic Modulus | ~206 GPa |
| Spring Rate (Approx.) | 500–700 N/mm (depending on stack configuration) |
| Deflection at Rated Load | 180–240 mm |
| Operating Temperature Range | -40°C to +120°C |
| Inter-Leaf Protection | Equipped with wear-resistant shims or solid lubricant coating (e.g., PTFE-based) |
| Corrosion Resistance | Surface-coated for protection; recommend periodic cleaning and grease application |
