Axle Hub Reduction 81.35114.0110 Shacman

Product Introduction

This precision-engineered planetary gear assembly is the core of the wheel-end reduction system, designed to provide an additional gear reduction at the rear wheel hub to maximize torque and traction for heavy loads.

Structure & Material

• Material: High-strength alloy steel for the gears and carrier, precision-machined and heat-treated for exceptional hardness, wear resistance, and fatigue strength.

• Design: A compact planetary gearset housed in a robust carrier, with a splined input shaft connecting to the axle and an output flange for the wheel hub. The assembly is secured with high-strength bolts for reliability.

Performance

• Provides a final gear reduction at the wheel, significantly multiplying torque to handle heavy payloads and challenging terrain.

• The planetary design distributes load evenly across multiple gear teeth, ensuring smooth power delivery and reducing stress on individual components.

• It allows for a higher overall axle ratio, improving low-speed pulling power without compromising highway cruising efficiency.

Durability

• The heat-treated alloy steel construction withstands extreme torque loads, shock impacts, and the harsh environment of heavy truck operation.

• Precision-ground gears and a robust carrier ensure minimal wear and a long service life, even in demanding off-road or long-haul applications.

Core Function

1. Torque Multiplication: Provides the final gear reduction to maximize torque at the wheel for heavy loads.

2. Load Distribution: The planetary design spreads torque across multiple gears, reducing stress and increasing durability.

3. Traction Enhancement: Increases low-speed pulling power for improved performance on steep grades or rough terrain.
