Product Description
AZ9231320273 SINOTRUK HOWO AC16 HC16 STR Inter Wheel Differential Assembly
Differential Assembly

The differential is a mechanism that allows the left and right drive wheels to rotate at different speeds. It ensures smooth turning and prevents tire scrubbing on uneven roads. Our assembly is composed of high-precision half axle gears, planetary gears, and a robust gear carrier.

Working Principles:
1. Power enters through the driven gear and bevel gear to drive the housing.
2. Two half shaft gears distribute power to the wheels.
3. Planetary gears rotate around their shaft and revolve around the axle shaft axis to compensate for speed differences.
