What is the FAW Air Horn Logic Assembly

  • The FAW Air Horn Logic Assembly is the intelligent electronic control unit governing the powerful pneumatic horn system on FAW commercial trucks. This sophisticated assembly processes driver inputs and manages the electrical signals activating the air solenoid valves. Its “logic” ensures reliable, immediate horn response, protects the electrical system, and may enable features like diagnostic feedback or multi-tone patterns. Precise operation of the Air Horn Logic Assembly is critical for delivering the loud, attention-commanding audible warnings essential for heavy-duty vehicle safety.
  • The physical sound generation is handled by the Air Horn Assembly, a robust pneumatic device producing the characteristic loud blast. Often, this Air Horn Assembly incorporates an Air Horn Assembly With Pipe Connector, featuring integrated fittings for the compressed air supply line. Mounting this horn securely requires a sturdy Air Horn Bracket Assembly, designed to withstand significant vibration and provide optimal sound projection while isolating the horn from the chassis.
  • Securing the entire system demands heavy-duty, vibration-resistant hardware:
  • Hexagon Flange Bolt (Thick Rod – Standard Type): Used for primary structural attachment of the Air Horn Bracket Assembly to the truck frame. The thick rod provides extra shear strength, while the integrated flange acts as a washer, distributing load and resisting loosening.
  • Hexagon Flange Nut: Paired with bolts (potentially another Hexagon Flange Bolt) to clamp the Air Horn Assembly firmly onto the Air Horn Bracket Assembly. The flange again enhances vibration resistance at the horn mounting point.
  • Special Shaped Seal Ring (Φ 6.5): Ensures an airtight seal at critical pneumatic connections within the horn assembly or at pipe fittings, preventing air leaks that would reduce sound volume or cause failure.
  • Circlip (Φ 6): Provides secure, removable retention for internal components like diaphragms or valve stems within the Air Horn Assembly, allowing for serviceability.
  • Threaded Sleeve (M10) With Seal Ring Assy: Creates a sealed, threaded port connection point for the compressed air line to attach securely to the Air Horn Assembly With Pipe Connector, combining mechanical strength with leak prevention.
  • M6 Cable Ties Assy: Used for neat and secure routing and bundling of the electrical wiring harness connecting the Air Horn Logic Assembly to the solenoid valves and power supply, preventing chafing and damage.
