Bevel Gear & Ring Gear Assembly 81.35199.6458 Foton

Product Introduction

This precision-machined gear set is the final stage of the vehicle’s drivetrain, designed to transfer torque from the longitudinal driveshaft to the rear axle’s transverse wheels while allowing for speed differentiation during turns.

• Structure & Material:

• Material: High-strength hypoid steel, precision-forged and heat-treated to achieve a hardened tooth surface and a tough, impact-resistant core.

• Design: A hypoid gear set consisting of a spiral bevel pinion (drive gear) and a large ring gear (driven gear), optimized for smooth meshing and high torque capacity.

• Finish: The gear teeth are precision-ground for optimal contact patterns, reduced noise, and minimal wear.

  • Performance:

• Transmits high torque loads efficiently, with the hypoid design enabling a lower driveshaft position for improved vehicle ground clearance.

• The spiral tooth design reduces noise, vibration, and harshness (NVH) while distributing load evenly across the gear teeth for increased durability.

  • Durability: The hardened steel construction withstands the high torque, shock loads, and continuous operation typical of heavy-duty vehicle use, ensuring long service life.

Core Function

1. Torque Transfer & Redirection: Transfers torque from the driveshaft to the rear axle, changing the direction of power flow by 90 degrees.

2. Differential Action: Allows the rear wheels to rotate at different speeds during turns, preventing tire scrubbing and improving handling.

3. Gear Reduction: Provides a final gear reduction to multiply torque for heavy load hauling and low-speed traction.
