Product Descreiption
The Dongfeng T2500 Brake Drum is a high-performance braking component designed for the rear axle systems of Dongfeng’s medium- and heavy-duty commercial trucks, including cargo vehicles, construction trucks, and distribution fleets. Engineered to deliver exceptional stopping power, thermal stability, and long-term durability, the T2500 brake drum meets Dongfeng’s rigorous OEM standards for safety, reliability, and cost-efficiency. Built with advanced materials and precision manufacturing, this brake drum ensures consistent braking performance under heavy loads and extreme operating conditions.
Key Specifications
- Application Compatibility:
- Vehicle Models: Fits Dongfeng’s T2500 series trucks, including the DFL5160, DFL5250, Tianlong KL, and KR models (4×2, 6×4, and 8×4 configurations).
- Axle Type: Designed for rear drum brake systems on 10-ton to 13-ton capacity axles, compatible with Dongfeng’s standard rear axle assemblies.
- Material & Construction:
- Brake Drum Body: High-grade cast iron (e.g., GG25 or FC250) with optimized graphite structure for enhanced thermal conductivity and crack resistance.
- Surface Finish: Precision-machined braking surface with a roughness of ≤ Ra 3.2 μm, ensuring uniform friction and reduced brake fade.
- Heat Treatment: Annealed and stress-relieved to prevent warping during high-temperature braking cycles.
- Dimensions:
- Outer Diameter: ~400–420 mm (15.75–16.54 inches) (varies by vehicle model).
- Inner Diameter (Braking Surface): ~360–380 mm (14.17–14.96 inches).
- Width: ~130–150 mm (5.12–5.91 inches).
- Bolt Circle Diameter (PCD): 10 x 285 mm (10-bolt pattern, 285 mm pitch circle diameter) or 8 x 275 mm (customizable for specific axles).
- Center Bore: ~165–175 mm (6.50–6.89 inches).
- Weight: ~40–50 kg (88.2–110.2 lbs) (depending on size and material).
- Braking Performance:
- Maximum Operating Temperature: Up to 650°C (1,202°F) without deformation.
- Thermal Conductivity: High iron content ensures rapid heat dissipation, minimizing brake overheating.
- Friction Coefficient: Compatible with standard semi-metallic or low-metallic brake linings.
- Load Rating:
- Static Load Capacity: Up to 13,000 kg (28,660 lbs) per drum (designed for GAWR ≤26,000 kg rear axles).
- Dynamic Load Rating: Meets ISO 26867:2009 and GB/T 5763 standards for commercial vehicle brake drums.
Technical Features
- Optimized Heat Management:
- Reinforced rib design increases surface area for improved cooling, reducing the risk of brake fade during prolonged use.
- Uniform wall thickness (24–30 mm) balances weight and thermal performance.
- Durability & Longevity:
- High-carbon cast iron resists cracking and spalling under repeated thermal stress.
- Corrosion-resistant coatings (e.g., black oxide or zinc phosphate) protect against rust in harsh environments.
- Precision Engineering:
- Tight dimensional tolerances (≤0.1 mm runout) ensure even brake lining wear and smooth operation.
- Compatible with automatic slack adjusters for reduced maintenance.
- Easy Installation & Maintenance:
- Direct OEM replacement for part number T2500, ensuring seamless fitment.
- Modular design allows for quick inspection and replacement without axle disassembly.
