What is the FAW Intermediate Axle Assembly-Wheel Hub Assy

  • 1. FAW Intermediate Axle Assembly: Final Drive Interface
    The Wheel Hub Assy is the critical load-bearing endpoint of the FAW Intermediate Axle Assembly. It directly transfers multiplied torque from the reduction gears to the vehicle’s wheels while supporting the entire vehicle weight. This robust assembly ensures reliable power delivery and handling stability for FAW trucks under demanding payloads and road conditions.
  • 2. Wheel Hub: Core Load Carrier
    The forged Wheel Hub forms the central structural component. Engineered for extreme radial and axial loads, it features precision-machined surfaces for mounting the wheel assembly and provides the inner raceway for the bearings. Its design integrates seamlessly with the axle shaft and brake components, forming the final rotating link to the road.
  • 3. Dual Bearing Support System
    High-capacity tapered roller bearings provide critical support:
  • The Inner Bearing handles primary radial loads closest to the axle centerline and manages inward axial forces.
  • The Outer Bearing absorbs significant radial loads near the wheel mounting flange and controls outward axial thrust during cornering and acceleration.
    This dual-bearing configuration ensures smooth rotation, precise wheel alignment, and extended service life under heavy stress.
  • 4. Bearing Shield: Contaminant First Defense
    Positioned adjacent to the bearings, the Bearing Shield acts as the primary physical barrier against large contaminants like dirt, gravel, and road debris. This rigid shield deflects particles away from the critical seal and bearing areas, significantly enhancing the longevity of the internal components within the harsh wheel-end environment.
  • 5. Hub Oil Seal Assembly: Critical Fluid Retention
    The Hub Oil Seal Assembly is paramount for preventing lubricant leakage and contaminant ingress. This multi-lip, spring-loaded seal creates a dynamic barrier between the rotating Wheel Hub and the stationary axle spindle or housing. It maintains vital gear oil within the hub cavity, ensuring continuous lubrication of the bearings and protecting against premature wear and corrosion.
  • 6. O-ring: Static Sealing Assurance
    Complementing the dynamic seal, a high-temperature resistant O-ring provides reliable static sealing. Typically seated between non-rotating housing components (like the brake backing plate and the axle tube flange), this elastomeric ring prevents moisture, dirt, and splash water from entering the assembly from the exterior, safeguarding internal lubricants and components.
  • 7. Wheel Bolt: Secure Wheel Retention
    Critical for safety, the hardened Wheel Bolts (or studs) are pressed or threaded directly into the Wheel Hub flange. These high-tensile fasteners provide the clamping force necessary to securely attach the vehicle’s wheel assembly. Their precision ensures proper wheel centering and withstands immense shear and vibrational forces encountered during operation.
