What is the FAW Rear Axle Assembly-Casting Brake

  • This integrated assembly provides reliable, heavy-duty stopping power for FAW commercial vehicles, utilizing a durable cast brake base foundation.
  • Rear Axle Assembly: The core structure housing the entire drivetrain and braking system. This heavy-duty casting integrates the differential, axle shafts, wheel ends, and the critical Casting Brake components, designed for maximum strength and load-bearing capacity.
  • Casting Brake Base: The primary, high-strength cast iron housing that forms the foundation of the brake system. It provides mounting surfaces and anchor points for all other brake components, ensuring rigidity and heat dissipation during braking. Houses the Brake Bottom Plate Assy and critical Bearing.
  • Brake Bottom Plate Assy: This assembly, mounted securely to the Casting Brake Base, serves as the central anchor point for the brake actuation mechanism. It incorporates the Brake Bottom Plate, Oil Seal Sleeve (protecting the camshaft bearing area), Spring Collar For Hole (likely a bushing or spacer), Bearing (supporting the S-camshaft), and the Brake Base Oil Seal (preventing lubricant leaks and contamination ingress).
  • Brake Shoe Assembly: The core friction-generating unit. It consists of the Brake Bottom Plate (acting as the shoe table/platform), Friction Plates (riveted or bonded brake linings), Rivets (securing the friction material), and often integral Shields (heat dissipation fins). This assembly is forced outward against the rotating Dust Brake Disc (the brake drum) to create stopping force.
  • Retraction Mechanism: Ensures the brake shoes disengage cleanly after braking. Key elements include:
  • Retraction Springs: Powerful coil springs that pull the brake shoes back away from the drum.
  • Hanging Spring Pin / Spring Straight Pin / PIN: Various pins used to anchor and connect the retraction springs to the brake shoes and anchor points.
  • Circlip for Shaft: Secures components like pins or spacers on shafts within the assembly.
  • Roller: Typically found on the ends of the brake shoes, these roll against the S-cam profile for smooth, low-friction actuation.
  • Actuation & Hardware:
  • Hexagon Head Bolt & Spring Washer Assy: High-tensile bolts with integrated locking washers, used extensively to secure major components like the Brake Bottom Plate Assy to the Casting Brake Base and the Dust Brake Disc to the wheel hub.
  • Plug: Seals access ports (e.g., for adjusting brake clearance) in the Dust Brake Disc or backing plate.
  • Splint / Harness Fixed Piece: Secures brake chamber pushrods or air lines/harnesses, preventing vibration-induced damage or disconnection.
  • Seals & Shields:
  • Oil Seal Sleeve / Brake Base Oil Seal: Critical seals preventing lubricant leakage from the camshaft bearing area and contamination ingress.
  • Shield: Often refers to heat dissipation fins integrated into the Brake Shoe Assembly or backing plate.
  • Harness Shield Sleeve: Protective conduit or sleeving guarding brake air lines or electrical sensor wiring from abrasion, heat, and road debris.
  • Lubrication & Sensor:
  • Embellish Nipple (Grease Fitting): Standard grease nipple (Zerk fitting) mounted on the Casting Brake Base or Brake Bottom Plate Assy, allowing periodic lubrication of the S-camshaft bushings/bearings.
  • Sensor: Often an automatic brake adjuster stroke sensor or a wheel speed sensor (ABS) integrated into the brake assembly, providing vital data to the vehicle’s control systems.
  • Dust Brake Disc: The large, cast iron rotating drum attached to the wheel hub. The Brake Shoe Assembly presses against its internal friction surface to generate stopping power. Features a Plug for adjustment access and mounting holes for Hexagon Head Bolt & Spring Washer Assy.
  • The FAW Casting Brake system within the Rear Axle Assembly exemplifies heavy-duty engineering. From the foundational Casting Brake Base and anchored Brake Bottom Plate Assy, through the friction-generating Brake Shoe Assembly and Dust Brake Disc, to the critical Retraction Springs, Seals, Bearings, and Sensors, each component – including the numerous Pins, Rivets, Splints, and Bolts – is designed for reliability, durability, and effective braking performance under the most demanding conditions.
