What is the FAW Traction Saddle Seat Plate Module

  • 1. FAW Traction Saddle Seat Plate Module: The Pivot Point for Heavy Hauling
    The FAW Traction Saddle Seat Plate Module forms the critical interface between a FAW tractor unit and its semi-trailer. This robust assembly anchors the fifth wheel mechanism, enabling secure articulation, efficient load transfer, and stable towing for demanding freight applications. Engineered for extreme durability, it withstands immense vertical, horizontal, and torsional forces encountered during transport.
  • 2. Core Assembly: Traction Seat & Seat Plate Integration
    The heart of the module is the Traction Seat & Seat Plate Assembly. This precision-machined unit integrates the load-bearing Saddle Type Traction Seat (the upper receiver surface) with the reinforced Saddle Bottom Plate (the primary mounting base). This welded or forged assembly creates a unified, high-strength platform that distributes trailer weight evenly across the tractor’s frame rails.
  • 3. Saddle Type Traction Seat: Precision Coupling Surface
    The Saddle Type Traction Seat features a specifically contoured, hardened surface designed to mate seamlessly with the semi-trailer’s kingpin. Its geometry ensures smooth coupling/uncoupling, minimizes wear, and provides consistent, secure locking engagement during operation, even on uneven terrain or under dynamic loads.
  • 4. Structural Mounting: High-Strength Fastening System
    Securing the entire module to the tractor chassis with uncompromising integrity relies on a heavy-duty fastening system:
  • Primary & Reinforcement Bolts: Multiple Hexagon Flange Bolt Thick Rod (Standard Type) fasteners are strategically employed. Their Thick Rod design provides exceptional shear strength and resistance to bending stresses. The integrated Hexagon Flange acts as a built-in washer, distributing clamping force widely on the Saddle Bottom Plate and chassis mounting points.
  • Complementary Hardware: Each bolt interfaces with a Washer (further enhancing load distribution and surface protection) and is secured by an SPL Small Hexagon Flange Lock Nut. This specialized lock nut features a serrated flange that bites into the mating surface, creating a prevailing torque lock that resists vibration-induced loosening critical for safety. The repetition of bolt listings signifies their essential use at primary mounting, secondary reinforcement, and potentially pivot point locations within the assembly.
  • 5. Saddle Bottom Plate: Foundation & Force Distribution
    The Saddle Bottom Plate is the massive structural baseplate of the assembly. Fabricated from high-grade steel, it provides the extensive mounting surface area necessary to bolt the module firmly to the tractor frame. Its primary function is to absorb and distribute the massive compressive, tensile, and shear forces generated by the trailer load across the strongest sections of the chassis, preventing localized stress concentrations.
