Product Descreiption
The Dongfeng Kinrun MK02C Brake Drum is a high-performance braking component engineered for the rear axle of Dongfeng’s medium- and heavy-duty commercial vehicles, including trucks, buses, and specialized transport equipment. Designed to deliver reliable stopping power, exceptional heat dissipation, and extended service life, this brake drum is a critical safety feature for vehicles operating under demanding conditions. Built to Dongfeng’s rigorous OEM standards, the MK02C brake drum combines advanced materials, precision engineering, and optimized thermal management to ensure consistent braking performance, reduced maintenance costs, and enhanced driver safety.
Key Specifications
- Application Compatibility:
- Vehicle Models: Fits Dongfeng’s Kinrun series trucks (e.g., DFL5160, DFH5250), as well as other models like Tianlong, KR, and D7 series (4×2, 6×4, and 8×4 configurations).
- Axle Type: Designed for rear drum brake systems, compatible with 10-ton to 16-ton capacity axles.
- Material & Construction:
- Brake Drum Body: High-grade cast iron (e.g., GG25 or FC250) with optimized graphite structure for improved thermal stability and crack resistance.
- Surface Finish: Precision-machined braking surface with a roughness of ≤ Ra 3.2 μm for consistent friction and reduced brake fade.
- Heat Treatment: Annealed and stress-relieved to prevent warping under high temperatures.
- Dimensions:
- Outer Diameter: ~410–430 mm (16.14–16.93 inches) (varies by vehicle model).
- Inner Diameter (Braking Surface): ~370–390 mm (14.57–15.35 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: ~160–170 mm (6.30–6.69 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 fade during prolonged braking.
- Friction Coefficient: Compatible with standard friction materials (e.g., semi-metallic or low-metallic brake linings).
- Load Rating:
- Static Load Capacity: Up to 16,000 kg (35,274 lbs) per drum (designed for GAWR ≤32,000 kg rear axles).
- Dynamic Load Rating: Meets ISO 26867:2009 and GB/T 5763 standards for commercial vehicle brake drums.
Technical Features
- Enhanced Heat Dissipation:
- Ventilated rib design increases surface area for improved cooling, reducing the risk of brake overheating and fade.
- Optimized wall thickness (25–30 mm) balances weight and thermal performance.
- Durability & Crack Resistance:
- High-carbon cast iron withstands repeated thermal cycling without cracking or spalling.
- 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 MK02C, ensuring hassle-free fitment.
- Modular design allows for quick inspection and replacement without axle disassembly.
