Product Descreiption
The Dongfeng Truck 400 Half Shaft is a critical drivetrain component designed for medium- and heavy-duty commercial trucks, including the Dongfeng EQ140, EQ145, EQ153, and similar 4×2 or 6×4 truck models. Engineered to transmit torque from the differential to the wheels with precision and reliability, this half shaft ensures smooth power delivery, durability under heavy loads, and long service life in demanding operating conditions.
Key Applications
- Dongfeng Truck Models:
- EQ140, EQ145, EQ153, EQ1141, EQ1168, and other 4–6-ton payload trucks.
- Dump trucks, cargo carriers, tankers, and municipal service vehicles.
- Industrial Use:
- Construction logistics, mining fleets, agricultural machinery conversions, and military transport vehicles.
Technical Specifications
- Material & Construction:
- Primary Material: High-strength alloy steel (40CrNiMoA or equivalent) with a tensile strength of ≥980 MPa (142,000 psi).
- Surface Treatment:
- Induction hardening for a case depth of 3–5 mm (0.12–0.20 inches) and a surface hardness of HRC 52–58.
- Phosphating and anti-rust coating for corrosion resistance in harsh environments.
- Splines: Precision-machined splines (28–32 teeth) with a modulus of 2.5–3.0 for secure torque transmission.
- Key Dimensions (Example: Dongfeng 400 Series Half Shaft):
- Total Length: ~1,200–1,500 mm (47.2–59.1 inches) (varies by truck model).
- Outer Diameter (Shaft Body): ~50–65 mm (1.97–2.56 inches).
- Flange Diameter (Wheel End): ~160–180 mm (6.30–7.09 inches) with 6–8 bolt holes (M14–M16).
- Weight: ~20–25 kg (44.1–55.1 lbs).
- Design Features:
- One-Piece Forged Design: Eliminates welded joints for enhanced strength and fatigue resistance.
- Constant Velocity (CV) Joint Compatibility:
- Tripod-type CV joint at the differential end for smooth power transfer at high angles.
- Plunge-type CV joint at the wheel end for axial movement compensation.
- Grease-Lubricated Boots: High-temperature-resistant rubber boots with steel clamps to protect CV joints from contaminants.
- Performance Ratings:
- Maximum Torque Capacity: ~2,500–3,000 N·m (1,844–2,213 lb·ft) (depending on truck configuration).
- Operating Speed: Up to 3,000 RPM (continuous) and 4,000 RPM (peak).
- Temperature Range: -40°C to +120°C (-40°F to +248°F).
- Fatigue Life: >1,000,000 cycles under full load (tested per ISO 16750-3 standards).
Key Features
- High Durability & Load Capacity:
- Forged alloy steel construction withstands heavy towing, off-road impacts, and frequent starts/stops.
- Induction-hardened splines resist wear and deformation under high torque.
- Smooth Power Transmission:
- CV joints compensate for steering angles and suspension movement, ensuring vibration-free driving.
- Low-friction grease and sealed boots reduce maintenance needs.
- Corrosion & Wear Resistance:
- Phosphating and anti-rust coatings protect against salt, mud, and chemical exposure.
- High-temperature grease extends CV joint lifespan.
- Easy Installation & Compatibility:
- Direct OEM replacement for part numbers DF-400-HS-XXXX (refer to vehicle manuals for exact references).
- Modular design allows quick replacement without disassembling the entire drivetrain.
- Cost-Effective Performance:
- Reduces downtime due to drivetrain failures.
- Long service life lowers total cost of ownership (TCO).
