Planetary Carrier Assembly 81.35114.6113 Shacman

Product Introduction

This precision-engineered planetary carrier assembly is the structural hub of the rear axle differential, designed to support the planetary gears and facilitate smooth torque transfer between the axle shafts.

• Structure & Material:

• Material: The main housing is made of high-strength ductile iron, with precision-machined steel pins for the planetary gears.

• Design: An integrated, bowl-shaped carrier with a central mounting flange and internal pockets to hold the planetary gear pins. The assembly features a corrosion-resistant galvanized finish for the outer flange.

• Finish: The carrier housing is painted black for durability, while the mounting flange is galvanized for superior rust resistance. All mating surfaces are precision-machined for accurate gear alignment.

  • Performance:

• Provides a rigid and stable platform for the planetary gears, ensuring precise meshing with the sun gear and side gears for efficient torque distribution.

• Enables differential action, allowing the rear wheels to rotate at different speeds during turns while maintaining constant torque transfer.

  • Durability: The heavy-duty ductile iron construction withstands high torque loads, shock impacts, and the harsh environment of heavy truck operation, ensuring long service life.

  • Compatibility: Direct OE replacement, fully matching the dimensional, mounting, and gear alignment specifications of the original planetary carrier assembly.

Core Function

1. Gear Support: Holds the differential’s planetary gears in precise alignment with the sun gear and side gears.

2. Torque Distribution: Transmits torque from the ring gear to the axle shafts, enabling differential action during turns.

3. Structural Foundation: Acts as the main structural component of the differential, providing mounting points for the ring gear and axle bearings.
