Introduction to Truck Brake Shoes with Semi-Metallic Mixture
Semi-Metallic brake shoes mixture is a high-performance brake shoes friction material designed for heavy-duty trucks, combining metallic fibers (steel, copper-free alloys) with organic binders and ceramic additives. This brake shoes formula delivers superior braking efficiency, durability, and environmental compliance, making it a preferred choice for modern commercial vehicles. Below is a technical overview, advantages, and storage guidelines for this advanced friction material.
Technical Parameters of semi-metallic brake shoes mixes
| Parameter | Specification |
|---|---|
| Friction Coefficient (μ) | 0.40–0.55 (stable at 0–800°C) |
| Operating Temperature | -30°C to 800°C |
| Density | 3.0–3.5 g/cm³ |
| Thickness | 10–25 mm (customizable) |
| Shear Strength | ≥4.2 MPa |
| Noise Level | ≤75 dB (optimized damping) |
Note: Parameters vary based on formulations for specific applications, such as Hino 200 or Volvo trucks .
Advantages of semi-metallic brake shoes mixture
- High Thermal Stability
- The brake shoes friction materials maintain consistent friction performance even under extreme temperatures (up to 800°C), reducing brake fade during prolonged downhill braking .
- Extended Lifespan
- Reinforced metallic fibers enhance wear resistance, reducing replacement frequency by 20–30% compared to organic mixtures .
- Environmental Compliance
- Free from asbestos and heavy metals (e.g., copper), complying with global regulations like REACH and RoHS .
- Cost-Effectiveness
- Optimized brake shoes mixes balance performance and cost, ideal for high-load applications like cargo trailers and mining trucks .
- Low Dust Generation
- Ceramic additives minimize brake dust, protecting wheel components and reducing environmental contamination .
Packaging and Storage Guidelines
- Packaging:
- Sealed moisture-proof bags + reinforced cartons for bulk shipping, ensuring protection against humidity and physical damage .
- Labels include part numbers (e.g., WVA 29087, 29115) and certifications (IATF16949, E-mark) .
- Storage:
- Temperature: 10–30°C; Humidity: ≤60% .
- Avoid exposure to direct sunlight or corrosive environments to prevent material degradation .
Applications
The brake shoes formula is widely used in:
- Heavy-duty trucks (e.g., Hino 200, Volvo FH, MAN TGX) .
- Trailers and buses requiring high shear strength and thermal resistance .
- Off-road vehicles operating in harsh conditions (e.g., mining, construction) .
For OEM customization or technical specifications, refer to supplier catalogs .
This Semi-Metallic mixture combines robustness, environmental safety, and adaptability, making it a cornerstone of reliable truck braking systems.
