SINOTRUK HOWO Middle Axle Drive Assembly Main Reducer Axle Differential Assembly AZ9231320745
Compatible with HC16/ST16 dual rear axles; primarily used for Sinotruk's traditional 16-ton class dual-stage reduction drive axles.
Internal Core Components and Manufacturing Processes
1. Reinforced Differential: The assembly comes factory-equipped with a reinforced differential. Both the planetary gears and side gears are manufactured using a precision forging process, resulting in an impact load resistance that is over 20% higher than that of standard components.
2. Bearings and Seals: The unit features heavy-duty tapered roller bearings as standard, which offer superior heat and wear resistance. The housing oil seals have been reinforced to effectively block out mud and debris, preventing gear oil leakage-even under the high-temperature conditions typical of heavy-duty or mining operations.
3. Housing Quenching Process: The cast-steel main reducer housing undergoes a quenching process, which imparts exceptional overall rigidity. This prevents minor deformation of the housing when the heavy-duty vehicle encounters rough terrain or muddy conditions, thereby ensuring the precise meshing of the ring and pinion gears.
