What is the Foton Rear Axle Assembly-4

  • Foton Rear Axle Assembly-4: Precision Differential Lock Actuation System
  • The Foton Rear Axle Assembly-4 enables controlled engagement of the differential lock, providing driver-selectable traction enhancement for severe off-road and load conditions.
  • Driver Control Interface
  • Positive Engagement Mechanism:
    The DIFFERENTIAL LOCK PEDAL WELDMENT converts driver input into mechanical force. Its motion is guided by dual hardened PIN components ensuring ≤0.1mm alignment tolerance. The DIFFERENTIAL LOCK DIAL BLOCK provides visual lock status indication.
  • Sealed Control Points:
    Dual PLUG PIECE elements exclude contaminants from linkage pivot points, maintaining smooth operation in muddy/wet environments (IP67-rated).
  • Lock Engagement Transmission
  • Force Transfer Assembly:
    The DIFFERENTIAL LOCK FORK slides along the DIFFERENTIAL LOCK FORK SHAFT, converting linear motion into rotational force. A SPRING COLUMN PIN maintains fork alignment during high-vibration operation.
  • Hydraulic Isolation:
    An O-SEAL RING prevents fluid migration between axle chambers during lock actuation.
  • Return & Safety System
  • Automatic Disengagement:
    The DIFFERENTIAL LOCK RETURN SPRING ensures positive lock release when pressure is removed, preventing drivetrain binding during pavement operation.
  • Vibration-Proof Retention:
    BOLT and NUT fasteners with integrated washers secure the assembly under 12G impacts. Critical joints feature secondary PIN retention.
  • Performance Specifications
  • Lock engagement time: 0.8 seconds @ -30°C
  • Fork shaft travel: 22mm ±0.5mm
  • Return spring force: 120N ±5%
  • Operating temperature: -40°C to 110°C
  • 50,000+ engagement cycles
