What is the FAW Frame Logic Assembly

  • 1. FAW Frame Logic Assembly: The Chassis Backbone
    The FAW Frame Logic Assembly forms the primary structural foundation for heavy-duty FAW trucks. This meticulously engineered ladder frame system, comprising interconnected Longitudinal Member Assemblies and strategically placed cross-members, distributes immense payload and dynamic stresses, ensuring chassis rigidity, stability, and longevity under extreme operating conditions.
  • 2. Longitudinal Beam Structure: Core Load Paths
  • Left/Right Longitudinal Member Assy: The main load-bearing rails, featuring the Left Rail and Right Rail as primary extrusions.
  • Reinforcement: Enhanced by Inner Reinforcing Plate Of Left Longitudinal Beam and Inner Reinforcing Plate Of Right Longitudinal Beam, significantly boosting bending and torsional resistance.
  • Front Extensions: Frame Left Front Add Long Beam and Frame Right Front Add Long Beam extend the frame rails forward for specific configurations, secured with Hexagon Flange Bolt Thick Rod (Standard Type) and SPL Small Hexagon Flange Lock Nut.
  • 3. Cross-Member Network: Transverse Stability & Component Mounting
  • Front Section: The Front Cross Member Assy provides crucial front-end rigidity. Right Front Spring Front Bracket Cross Member Welding Assembly, Left Front Bracket-Front Leaf Spring, and Right Front Bracket-Front Leaf Spring integrate spring hangers. Mounting uses Hexagon Flange Bolt Thick Rod (Standard Type) and SPL Small Hexagon Flange Lock Nut.
  • Center Section: Middle 1# Cross-Member Riveting Assembly and Middle Cross Member bridge the frame center. Connection involves Middle Cross Member Left/Right Upper/Lower Connecting Boards and Round Head Rivets for permanent, high-shear strength joints.
  • Rear Section: The Rear Cross Member handles rear axle loads. It interfaces via Rear Cross Member LH/RH Upper Connection Plates and Rear Cross Member Left/Right Lower Connecting Plates, utilizing Hexagon Flange Lock Nuts, Hexagon Flange Bolt Thick Rod (Standard Type), and Round Head Rivets.
  • 4. Balance Suspension Integration: Multi-Axle Load Distribution
  • Core Component: The Balance Suspension Cross Beam Assy, centered around the Balance Suspension Cross Beam.
  • Connection: Linked to the frame via Upper Connecting Board-Balance Suspension Cross Beam Assy, Lower Connecting Plate, Left Connecting Plate-Balance Suspension Cross Beam Assy, Left/Right Brackets, and Reinforced Plates.
  • Fastening: Employs Hexagon Flange Bolt Thick Rod (Standard Type), SPL Small Hexagon Flange Lock Nut, Hexagon Flange Lock Nut, and Round Head Rivets for robust, vibration-resistant connections critical for load sharing between axles.
  • 5. Critical Brackets & Saddles: Subsystem Anchoring Points
  • General Brackets: Left Bracket, Right Bracket, Upper Bracket, and Bracket Assembly-Hanging Balance Cushion provide mounting points for suspensions, cab mounts, or other subsystems. Secured with combinations of Hexagon Flange Bolt Thick Rod (Standard Type), Hexagon Flange Bolt, SPL Small Hexagon Flange Lock Nut, and Washers.
  • Saddle Mounts: Left saddle bottom plate connection plate and Right saddle bottom plate connection plate interface with fifth wheel or other saddle assemblies, using Hexagon Flange Bolt Thick Rod (Standard Type).
  • 6. A-Beam Connection System: Reinforced Joints
  • Structural Interface: The A Beam Left/Right Upper Connecting Plates and A Beam Left/Right Lower Connecting Plates create reinforced junctions, likely for cab or powertrain support.
  • Fastening: Utilizes Hexagon Flange Bolt Thick Rod (Standard Type) and Round Head Rivets for high-integrity connections.
  • 7. Fastening Philosophy: Vibration Resistance & Integrity
  • High-Strength Bolting: Repeated use of Hexagon Flange Bolt Thick Rod (Standard Type) ensures exceptional shear strength. Paired with SPL Small Hexagon Flange Lock Nut or Hexagon Flange Lock Nut and often Washers, these create vibration-proof, fail-safe connections.
  • Permanent Riveting: Round Head Rivets provide superior, permanent shear strength at critical, high-stress joints like cross-member connections, ensuring long-term dimensional stability.
