Product Introduction
The Front Axle Assembly is a core chassis component for Shaanxi Heavy-Duty Trucks (e.g., DeLong L3000 series), engineered to deliver exceptional braking performance, durability, and maintenance efficiency. It integrates a disc brake system and low-maintenance design, specifically optimized for heavy-load transport in mining, construction, and logistics applications.
Highlight Advantages
500,000 km Maintenance-Free Operation
⦿ Utilizes German-made FAG bearing units and sealed lubrication systems, eliminating routine greasing or adjustments for 500,000 km-reducing downtime and lifecycle costs by ≥30%.
Extreme Braking Performance
⦿ Max Braking Torque of 28,000 N·m-highest in its class-ensures rapid deceleration even under full loads.
⦿ Ventilated Disc Brakes dissipate heat 15% faster than drum alternatives, preventing thermal fade during prolonged braking in mountainous terrain.
Robust Structural Design
⦿ Forged I-Beam Axle (e.g., HDM 7.5T model) with CAE-optimized geometry balances strength and weight, supporting loads up to 4.8 tons while resisting deformation.
⦿ Integrated Steering Knuckle-Transition Plate reduces parts count and failure points, enhancing reliability.
Precision Steering & Maneuverability
⦿ Large-Bore Steering Cylinder (100 mm diameter) and 46° steering angle enable tight turning radii (e.g., urban alleys, construction sites).
⦿ Modular Compatibility with Shaanxi's *AC26/MCY13* chassis systems, enabling plug-and-play installation.
Corrosion & Wear Resistance
⦿ Zinc-Manganese Phosphating + Epoxy Coating protects against rust and chemical exposure in harsh environments (e.g., coastal routes, de-icing roads).
Target Customers
Long-Haul Logistics Fleets
⦿ Operators prioritizing low TCO; 500,000-km maintenance intervals cut servicing frequency and costs.
Mining & Construction Companies
⦿ Demanding applications (e.g., Tongli 855 dump trucks) benefit from high torque braking and overload resilience.
Urban Delivery & Regional Transport
⦿ Fleet managers needing agile maneuverability for tight spaces (46° steering) and fuel-efficient disc brakes.
Aftermarket Service Providers
⦿ Workshops seeking OEM-compatible axles (e.g., part nos. HDM7.5T, HDZ9.5T) with simplified installation and traceable QR codes.
Competitive Edge: Combines industry-leading braking torque, unmatched maintenance intervals, and agile handling-ideal for operators maximizing uptime in demanding transport sectors. For OEM specifications, refer to models like DeLong L3000 or patents (e.g., integrated knuckle design)
