What is the FAW Rear Axle Assembly-Axle Housing Assy

  • FAW Rear Axle Assembly-Axle Housing Assy: The Heavy-Duty Foundation
  • The FAW Rear Axle Assembly-Axle Housing Assy forms the robust structural core and functional powerhouse of the drivetrain in FAW trucks and heavy-duty commercial vehicles. This integrated system houses critical components responsible for final gear reduction, torque multiplication, wheel driving, and foundation braking, engineered for maximum load-bearing capacity and durability under extreme operating conditions.
  • Structural Foundation & Power Transfer
  • Axle Housing Assy: This heavy-duty, ductile iron or fabricated steel housing provides the rigid backbone. It encloses the differential, supports the wheel ends, and withstands immense chassis loads and driveline torque.
  • Rear Reducer Assy: The heart of the axle, containing the ring and pinion gears for final drive reduction and the differential assembly distributing power to the Half Shafts.
  • Upper Reacting Rod Bracket: A crucial mounting point connecting the axle housing to the vehicle’s suspension reacting rods, managing braking and driving forces transmitted to the chassis.
  • Wheel Hub Assy: Precision-machined assemblies incorporating bearings, seals, and mounting flanges for the wheels and Brake Drums. They rotate on the axle spindles, driven by the Half Shafts splined into the Sun Wheel of the Wheel Reduction Gear Assy (where applicable).
  • Essential Sealing & Lubrication
  • Oil Seal Seat Ring: Provides the precise mounting surface for critical axle shaft oil seals, preventing gear oil leakage from the housing ends.
  • Baffle: Often installed inside the housing to optimize oil flow and ensure proper lubrication splash to gears and bearings.
  • Oil Filler Plug & Gasket: Allows for filling the axle housing with lubricant; the Oil Filler Plug Gasket ensures a leak-proof seal.
  • Oil Drain Plug: Located at the housing bottom for efficient lubricant changes.
  • Square-Sloted Tapered Magnetic Plug: Screws into the housing (often the drain or inspection port) to collect ferrous wear debris from the gear oil, providing vital maintenance insight.
  • Hexagon Tapered Plug: Used to seal auxiliary ports or inspection holes.
  • Braking System Integration
  • Brake Chamber Assembly (x2): Pneumatic actuators mounted directly to the Camshaft Bracket Assy on each side. They convert air pressure into mechanical force to actuate the S-cam brake mechanism.
  • LC300 Brake Subassembly (Left & Right): Complete assemblies for each wheel end, including shoes, rollers, anchors, and hardware, designed to interface with the Brake Drum.
  • Brake Drum: The rotating friction surface against which the brake shoes press.
  • Adjusting Arm (x2): Manual or automatic components attached to the Camshaft used to take up slack in the brake shoes as the linings wear.
  • Camshaft Bracket Assy (x2): Sturdy brackets mounted to the axle housing that support the Camshaft and provide the mounting point for the Brake Chamber Assembly.
  • Camshaft (x2): Rotating shafts driven by the brake chamber pushrod. Their rotation forces the S-shaped profile to expand the brake shoes against the Brake Drum.
  • Hex Head Bolt-Camshaft Bracket (x2): High-strength bolts specifically designed to secure the Camshaft Bracket Assy firmly to the axle housing flange.
  • Spring Sliding Plate: Facilitates smooth movement of brake shoe return springs.
  • Cross Head Screw: Often used to secure brake drum components or inspection covers.
  • Drivetrain & Gear Components
  • Half Shaft (x2): Solid or semi-floating shafts transmitting torque from the differential side gears to the Sun Wheel of the Wheel Reduction Gear Assy.
  • Wheel Reduction Gear Assy: (If equipped) A planetary gear set mounted at each wheel end, driven by the Half Shaft via the Sun Wheel, providing additional torque multiplication and reducing load on the axle shafts and differential.
  • Sun Wheel: The input gear of the planetary reduction set, splined to the Half Shaft.
  • Sun Wheel Gasket: Seals the interface between the reduction gear housing and the axle housing end.
  • Adjusting Gasket: Shims used for precise setting of bearing preload or gear backlash in the reduction gear assembly.
  • Gear Ring And Bracket Assy: Houses the ring gear for the planetary reduction set and mounts it to the axle housing/wheel hub.
  • Circlip For Shaft 35, Hole Circlip: Retaining rings securing gears, bearings, or shafts within the reduction assembly or differential.
  • Lock Nut: Secures critical rotating components like bearing cones or the reduction gear carrier.
  • Screw, Twelve Point Cap: High-torque fastener often used on ring gear carriers or differential covers.
  • End Cover: Seals the outer end of the wheel reduction gear assembly.
  • ABS & Sensor Integration
  • LB300 Gear Ring-ABS: The toothed impulse ring mounted on the wheel hub or axle shaft, rotating past the ABS sensor.
  • LB300 Sensor Bracket: Holds the ABS sensor at the precise air gap distance from the LB300 Gear Ring-ABS.
  • LB300 Switch, Pressure: Monitors air pressure within the brake system, potentially for ABS/TCS control or warning systems.
  • Sensor Bale Of Wire: The wiring harness connecting the ABS wheel speed sensors to the vehicle’s electronic control unit (ECU).
  • 457 Bush Of Sensor: Likely a mounting bushing or spacer ensuring correct sensor positioning.
  • Securing & Fastening
  • Bolt, Tightening Bolt (x4), Locking Nut: Generic terms representing the myriad of high-strength Bolts, specialized Tightening Bolts (often for hub bearings), and Locking Nuts used throughout the assembly. Wire Spring may refer to a specific locking wire application.
  • Hex Head Bolt: Versatile fastener used for various covers and brackets.
  • This meticulously engineered FAW Rear Axle Assembly-Axle Housing Assy, integrating every specified component from the Upper Reacting Rod Bracket to the 457 Bush Of Sensor, delivers unmatched strength, reliable power transfer, and critical braking performance, forming the bedrock of FAW’s heavy-duty drivetrain solutions.
