2. Core Design & Structure

  • Dual Countershaft Main Box: Splits torque evenly between two countershafts, reducing gear load, improving durability, and extending service life.
  • Planetary Auxiliary Box: Provides high/low range shift with synchromesh, ensuring smooth and quick range changes.
  • 5×2 Compound Transmission: 5 main gears × 2 auxiliary ranges = 10 forward gears; no synchronizers in main box (robust for heavy loads), synchromesh only in auxiliary box.
  • Integral Cast Housing: High rigidity, low noise, good vibration resistance; optimized ribbing for heavy-duty conditions.
  • Combined Lubrication: Forced pressure lubrication + splash lubrication; ensures adequate oil supply to gears/bearings under steep slopes or heavy loads
