What is the Foton Final Transmission Assembly -1

  • Foton Final Transmission Assembly-1: Planetary Reduction Hub for Extreme Torque Applications
  • The Foton Final Transmission Assembly-1 integrates precision planetary gearing and robust sealing technology to deliver maximum torque multiplication at the wheel end, engineered for mining, construction, and heavy-haul operations.
  • Planetary Gear Reduction Core
  • Torque Multiplication System:
    Three PLANET GEAR units rotate on hardened PLANET GEAR SHAFT pins within the PLANET CARRIER. These mesh with the stationary GEAR RING and the splined LEFT HALF SHAFT, achieving 4:1 reduction ratios.
  • Needle Bearing Efficiency:
    NEEDLE rollers run between NEEDLE OUTER SPACER RING and NEEDLE INNER SPACER RING components, reducing friction by 45% versus bushings. BALL BEARING units handle axial loads at the carrier ends.
  • Precision Adjustment & Retention
  • Micron-Level Calibration:
    Quadruple ADJUSTING WASHER shims (0.10–0.35mm thickness range) set bearing preload within ±3% tolerance. A SPACER BUSH maintains gear alignment under 12,000 N·m torque.
  • Positive Shaft Locking:
    The DRIVING SHAFT is secured by a DRIVING SHAFT LOCK BOLT acting on a DRIVING SHAFT LOCK PIECE, backed by a RETAINER BLOCK against rotational forces.
  • Sealed Housing Architecture
  • Triple-Containment Sealing:
  • O-SEAL RING at housing joints
  • O RING dynamic shaft seals
  • OIL SEAL CAGE reinforced lip seals
  • Structural Enclosure:
    The LEFT DRIVING SHAFT HOUSING incorporates dual PIN dowels for perfect alignment. Sealed by HEXAGON NUT, TYPE-2 with WASHER at the hub interface.
  • Durable Fastening System
  • High-Shear Connections:
    REAR HUB BOLT (LEFT) and BOLT fasteners (ISO 10.9) secure components with 320 N·m torque. Flanged WASHER elements distribute load at stressed joints.
  • Performance Advantages
  • 98.5% mechanical efficiency at peak load
  • Oil retention: 0% leakage after 2,000 hrs @ 110°C
  • Bearing L10 life: 15,000+ hours
  • -30°C cold-start capability
