Product Descreiption
The Dongfeng Truck Cross Axle, also known as the Drive Shaft Cross Assembly or Universal Joint Cross, is a critical component in the vehicle’s driveline system, enabling smooth power transmission between the transmission and the drive wheels while accommodating angular misalignment and vibrations. Engineered to Dongfeng’s OEM standards, this cross axle ensures durability, reliability, and efficient torque delivery in medium- and heavy-duty commercial trucks.
Key Applications
- Compatible Dongfeng Truck Models:
- EQ140, EQ145, EQ153, EQ1168, EQ1250, EQ2102, and other 6×4, 8×4, or 4×2 cargo trucks, dump trucks, buses, and military/special-purpose vehicles.
- Ideal for applications requiring robust driveline components to handle high torque, heavy loads, and off-road conditions.
- Industrial Use:
- Mining trucks, agricultural machinery conversions, and construction equipment.
Technical Specifications
- Material & Construction:
- Primary Material:
- Alloy steel (20CrMnTi or equivalent) for the cross journal and bearing caps (case-hardened for wear resistance).
- Carbon steel (45# steel) for the spider (center body) with induction hardening.
- Bearing Type:
- Needle roller bearings with high-load capacity and low friction.
- Sealed-for-life grease (e.g., lithium-based EP2 grease) for long-term lubrication.
- Surface Treatment:
- Zinc plating or black oxide coating for corrosion resistance.
- Phosphate finish on bearing surfaces to improve grease retention.
- Primary Material:
