What is the Foton Rear Axle Assembly-2

  • Foton Rear Axle Assembly-2: Precision Gear Engagement & Reverse Power Transfer
  • The Foton Rear Axle Assembly-2 integrates specialized reverse gearing and torque distribution systems, engineered for reliable backup operation and optimized power delivery in commercial drivetrains.
  • Core Gear Shaft Systems
  • Hypoid Input Stage:
    The SMALL TAPER GEAR SHAFT drives the ring gear at precise angles, adjusted via triple TAPER GEAR SHAFT ADJUSTING GASKET shims (0.05-0.25mm thickness range) for optimal tooth contact. Supported by a BEARING SEAT and secured with a ROUND NUT and THRUST RING, this assembly maintains ≤0.08mm axial play under 900 N·m torque.
  • Output Power Transfer:
    The FRONT DRIVE OUTPUT GEAR transmits torque through NEEDLE BEARINGS and SPACER BUSH components, reducing friction losses by 18% vs. conventional bushings.
  • Reverse Gear Mechanism
  • Idler Gear Engagement:
    The REVERSE IDLER GEAR rotates on the REVERSE IDLER GEAR SHAFT, guided by a REVERSE IDLER GEAR SHAFT SPACER SLEEVE. BLOCKING RING – HOLE synchronizers enable clash-free reverse shifts.
  • Driven Component Assembly:
    The REVERSE DRIVEN GEAR interfaces with the MESHING SEAT, actuated by the GEARSHIFT SHIFT COLLAR. The REVERSE MIDDLE SHAFT ASSEMBLY (housing REVERSE MIDDLE GEAR SHAFT) provides intermediate power transfer.
  • Bearing & Retention Systems
  • Precision Support Structure:
    Triple BEARING assemblies handle combined radial/thrust loads. The BEARING PRESSURE PLATE distributes clamping force evenly, while ADJUSTING WASHER shims control preload within ±5% tolerance.
  • Positive Locking:
    Multiple SNAP RING, RETAINER RING, and PIN components (3x hardened dowels) secure rotating elements against 10G shock loads.
  • Fastening & Sealing
  • Vibration-Resistant Hardware:
    M12 BOLT fasteners with conical WASHER elements maintain joint integrity under 15Hz resonant vibrations. SLEEVE spacers ensure proper gasket compression at critical interfaces.
  • Performance Validation
  • Reverse engagement time: ≤1.2 seconds at -25°C
  • 97.8% power efficiency at PTO speeds
  • 500,000 reverse shift cycles (ISO 14269-3)
  • Oil retention: 0% leakage after 1,000hrs @ 120°C
