What is the FAW Intermediate Axle Assembly-Casting Brake

  • 1. FAW Intermediate Axle Assembly: Robust Braking Foundation
    The Casting Brake integrated within the FAW Intermediate Axle Assembly provides the critical foundation for the heavy-duty S-cam drum brake system. This robust Brake Bottom Plate Assy, primarily comprising the Brake Bottom Plate casting, serves as the rigid, heat-dissipating anchor point for all brake components, ensuring reliable stopping power for FAW commercial vehicles under severe loads.
  • 2. Core Structure & Mounting
    The Brake Bottom Plate is a high-strength casting featuring precisely machined mounting points. Secured via high-tensile Hexagon Head Bolt & Spring Washer Assy combinations, it forms the rigid backbone of the system. Critical alignment and retention are ensured by hardened PINs, Spring Straight Pins, and Hanging Spring Pins, which locate and secure various linkages and levers relative to the plate.
  • 3. Brake Shoe & Friction Assembly
    Central to braking force are the Brake Shoe Assemblies. These leverage-mounted components hold the Friction Plate linings, pressed against the brake drum during operation. Each shoe assembly incorporates Rivets for secure lining attachment and interfaces with Rollers that ride on the S-cam profile. Retraction Springs (specified twice, likely for primary and secondary shoes) are crucial, actively pulling the shoes away from the drum when braking pressure is released, preventing drag and overheating.
  • 4. Camshaft & Actuator Interface
    The S-camshaft, responsible for expanding the brake shoes, rotates within the assembly. Key components here include the Circlip for Shaft, which axially locates the camshaft, and the Spring Collar for Hole, likely a wave spring or Belleville washer providing necessary end play control and preload within the camshaft bushings or bearings. The Bearing supports the camshaft end for smooth rotation.
  • 5. Sealing & Contaminant Protection
    Protecting internal mechanisms is paramount. The Brake Base Oil Seal prevents lubricant leakage from the axle ends into the brake mechanism. The Oil Seal Sleeve provides a wear surface for dynamic seals. The Dust Brake Disc acts as a primary shield against road debris and splash. Further protection comes from the Shield and Harness Shield Sleeve, guarding critical components like air lines or wiring from abrasion and impact. The Splint and Harness Fixed Piece secure brake chamber pushrods or pneumatic lines.
  • 6. Maintenance & Sensing Components
    Facilitating service and monitoring are essential smaller parts. The Embellish Nipple (grease fitting) allows periodic lubrication of critical pivot points like slack adjusters. The Plug seals unused ports within the casting. Modern systems often integrate a wear Sensor, monitoring friction plate thickness and signaling when brake maintenance is required.
