Product Descreiption
The Dongfeng TL380 Rear Wheel Hub is a heavy-duty, high-precision component engineered for the rear axle systems of Dongfeng’s medium- and heavy-duty commercial trucks, including freight carriers, construction vehicles, and specialized transport fleets. Designed to meet rigorous demands for load capacity, durability, and safety, the TL380 wheel hub combines advanced materials, precision manufacturing, and optimized engineering to deliver exceptional performance under extreme operating conditions. Built to Dongfeng’s strict OEM standards, this wheel hub ensures reliable power transmission, reduced maintenance costs, and extended service life.
Key Specifications
- Application Compatibility:
- Vehicle Models: Ideal for Dongfeng Tianlong KL, KR, D7, and DFL5250 series trucks (6×4, 8×4 configurations) and other models with rear drum brake systems.
- Axle Type: Compatible with 13-ton to 16-ton capacity rear axles, including Dongfeng’s standard and heavy-duty axle assemblies.
- Material & Construction:
- Hub Body: High-strength nodular cast iron (e.g., QT500-7 or FCD500) for superior tensile strength, impact resistance, and fatigue durability.
- Bearings: Double-row tapered roller bearings (e.g., 32220 or equivalent) pre-loaded for optimal load distribution and reduced friction.
- Sealing: Triple-lip oil seals and dust caps to prevent contamination and retain lubricant.
- Surface Treatment: Anti-corrosion coating (e.g., electro-deposition paint or zinc-nickel plating) for rust resistance in harsh environments.
- Dimensions:
- Outer Diameter: ~420–440 mm (16.54–17.32 inches) (hub flange diameter).
- 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: ~170–180 mm (6.69–7.09 inches) (matches axle spindle diameter).
- Width (Hub Face to Flange): ~200–220 mm (7.87–8.66 inches).
- Weight: ~35–45 kg (77.2–99.2 lbs) (depending on configuration).
- Load & Torque Ratings:
- Static Load Capacity: Up to 16,000 kg (35,274 lbs) per hub (designed for GVWR ≤32,000 kg rear axles).
- Dynamic Load Rating: Meets ISO 8643:2011 and GB/T 12230 standards for heavy-duty commercial vehicle wheel hubs.
- Maximum Torque: 15,000–18,000 N·m (11,060–13,276 lb·ft) (depending on axle ratio and gearing).
Technical Features
- Enhanced Durability:
- Nodular cast iron construction resists cracking, deformation, and wear under heavy loads and off-road conditions.
- Heat-treated bearing races and rollers ensure long-term reliability under high-speed rotation.
- Precision Engineering:
- Tight tolerances (≤0.05 mm runout) ensure smooth wheel rotation, reduced vibration, and even tire wear.
- Pre-assembled bearings with optimal preload settings minimize maintenance requirements.
- Sealing & Lubrication:
- Triple-lip seals retain high-viscosity gear oil (e.g., GL-5 85W-140) for extended bearing life.
- Drain and fill plugs for easy lubricant maintenance.
- Easy Installation & Maintenance:
- Direct OEM replacement for part number TL380, ensuring seamless fitment.
- Modular design allows for quick bearing replacement without disassembling the entire hub.
