What is the Dongfeng Front Wheel Drive Axle ( Right side-Slowdown )

  • Dongfeng Front Wheel Drive Axle (Right Side-Slowdown): Precision Torque Control for Balanced 4WD Performance
    Engineered as the mirrored counterpart to the left-side system, this right-side axle integrates a geared slowdown mechanism for symmetrical traction management. It delivers optimized power distribution during high-load operations while maintaining steering integrity across challenging terrain like slopes, plowed fields, and construction sites.
  • Final Drive Reduction & Power Transfer
  • Geared Speed Reduction: Features the Driving Bevel Gear of Final Drive meshing with the Driven Bevel Gear of Final Drive within the Right Final Drive Housing for controlled torque multiplication.
  • Precision Gear Alignment: Adjusting Shims for Final Drive enable micron-level backlash control and contact pattern optimization.
  • Bearing Load Management: Combines Ball Bearing 207, Ball Bearing 209, and Thrust Ball Bearing 8106 to handle radial forces and axial thrust during aggressive deceleration.
  • Primary Gear Stage & Upright Shaft Assembly
  • First Reduction Phase: The Driving Bevel Gear of the First Drive transfers power through the Upright Shaft to the Driven Bevel Gear of the First Drive.
  • Bearing Preload Calibration: Utilizes Adjusting Shims for the First Drive with Ball Bearings 305, 111, and 208 for vibration-free rotation under maximum load.
  • Axial Security: Blocking Ring of Upright Shaft and Lock Washer prevent shaft migration, while Straight Pin A10×20 maintains gear alignment.
  • Drive Shaft System & Sealing
  • Torque Transmission Core: The Drive Shaft connects via Drive Shaft Sleeve, secured by Fixing Ring of Drive Shaft and supported by Final Drive Housing Bushing.
  • Dual Lip Protection: Oil-Seal W50×72×7 and Oil-Seal PD50×72×12 create redundant barriers against lubricant leakage and contaminant ingress.
  • Shielded Access: Drive Shaft Cover with Gasket safeguards internal components from debris impact.
  • Steering Linkage Integration
  • Right-Side Control Points:
  • Right Linking Arm provides steering input through Steering Arm Bushing.
  • Right Steering Trapezoid Arm transmits directional control forces.
  • Secure Mounting: Fastened with Hex. Head Bolts (M12×35, M10×25) and Spring Lock Washers 12.
  • Sealed Lubrication & Service Design
  • Multi-Point Sealing: Utilizes O-Rings (56×2.65, 34.5×2.65, 85×2.65) at critical interfaces with Felt Washer supplementary protection.
  • Maintenance Access: Features Grease Cup M10×1 for manual lubrication and Oil Drain Plug with Combined Seal Washer for efficient fluid service.
  • Bearing Protection: Upper Bearing Cover and Lower Bearing Cover enclose precision components.
  • Robust Fastening & Structure
  • Vibration-Proof Hardware: Critical connections use Hex. Head Bolts (M18×1.5×35, M10×30) with Spring Lock Washers (18, 10) and Hex. Nut M18×1.5.
  • Reinforced Joints: Double Screw Bolt enhances high-stress point integrity.
  • Precision Spacing: Spacer elements maintain optimal gear clearances.
  • Engineered for Symmetrical Durability
    As the power-balanced counterpart to the left-side system, this axle integrates 38 specialized components – from the torque-output Half Shaft to the alignment-critical Straight Pin A10×28. The synergy between its dual-gear reduction stages (First Drive & Final Drive Bevel Gears), triple-bearing supported Upright Shaft, and sealed Right Final Drive Housing ensures matched torque management during heavy draft work. Exceeding OEM specifications, it delivers three critical advantages for right-wheel dynamics:
  • Balanced Traction Control: Synchronized slowdown with left axle
  • Reduced Torque Steer: Neutral handling during asymmetric loads
  • Extended Component Life: Optimized gear mesh prevents premature wear
