What is the Dongfeng Front Wheel Drive Axle ( Middle )

  • Dongfeng Front Wheel Drive Axle (Middle): Robust Power Transfer Core for Demanding 4WD Tractors
    Engineered as the critical pivot point in heavy-duty drivetrains, this center axle assembly delivers reliable torque transfer and precise steering articulation. Its heavy-duty construction withstands extreme loads while maintaining optimal gear alignment for peak agricultural and industrial performance.
  • Precision Geartrain & Differential System
  • High-Strength Gear Housing: The Main Drive Case houses the Bevel Drive Pinion Assembly and Differential Assembly, engineered for efficient power splitting.
  • Calibrated Gear Alignment: Utilizes Shims for Main Drive Case and Shims for Bearing Seat for micron-level gear tooth contact optimization.
  • Dual Differential Configuration: Features a robust Differential Assembly design for balanced torque distribution to both wheels.
  • Heavy-Duty Axle Housings & Support
  • Structural Pedestal System:
  • Front Pedestal & Rear Pedestal provide rigid mounting points, fitted with wear-resistant Front Pedestal Bush and Rear Pedestal Bush.
  • Shims for Front Swing Axle enable precise swing angle calibration.
  • Sealed Axle Terminations:
  • Left Half Shaft Housing and Right Half Shaft Housing incorporate large O-Ring Seals (160×3.55) for contaminant exclusion.
  • End Covers (Front/Rear Pedestal) with End Cover Gaskets and Gasket for End Cover ensure complete enclosure integrity.
  • Critical Sealing & Lubrication Management
  • Multi-Point Sealing: Utilizes specialized O-Ring Seals (65×2.65, 69×3.55, 69×2.65, 48.7×3.55) at all interfaces and Gasket for Upright Shaft Housing to prevent oil leaks.
  • Optimized Lubrication: Features Grease Cup M10×1 for manual bearing servicing and Oil Dipstick for level checks. Oil Drain Plug with Combined Seal Washer enables efficient fluid changes.
  • Pressure Equalization: Vent Plug and Vent Pipe prevent seal damage from thermal pressure buildup.
  • Secure Assembly & Steering Integration
  • Vibration-Resistant Fastening:
  • Critical Hex. Head Bolts (M16×65, M12×1.5×35, M10×35, M8×25, M6×12) with matching Spring Lock Washers (16, 12, 10, 8, 6) and Hex. Nut M16 maintain structural integrity under shock loads.
  • Straight Pins (A10×20, A10×16) provide positive alignment for key components.
  • Steering Compatibility: Power Steering Cylinder Bracket enables direct hydraulic cylinder mounting for responsive directional control.
  • Swing Axle Pivot: The Front Swing Axle facilitates steering articulation while Casing Cap protects internal components.
  • Engineered for Uncompromising Durability
    The Dongfeng Front Wheel Drive Axle (Middle) integrates over 30 precision components – from the Differential Assembly core to the smallest Spring Lock Washer 6 – into a unified power transfer solution. The synergy between its hardened geartrain, shim-adjusted alignment, triple-sealed housings (Main Drive Case, Half Shaft Housings), and industrial-grade fasteners delivers unmatched reliability in muddy fields, construction sites, and steep terrain. Exceeding OEM specifications, it maximizes uptime by preventing lubrication failure, gear misalignment, and structural fatigue.
