Inter-Axle Differential Ass DZ9114320706 Shacman

Product Introduction

This precision-engineered differential assembly is the central component of a tandem drive axle system, designed to distribute torque between the primary and secondary drive axles while accommodating speed differences between them during turns or uneven terrain.

Structure & Material

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

• Design: A compact planetary gearset housed in a forged steel carrier, featuring a splined input shaft and a locking mechanism for improved traction. The assembly includes a high-strength mounting nut for secure installation.

Performance

Automatically distributes torque between the two drive axles, ensuring optimal traction and power delivery in varying road conditions.

Accommodates speed differences between axles to prevent tire scrubbing and drivetrain wind-up, especially during cornering.

The robust design handles the high torque loads typical of heavy-duty truck applications, providing reliable performance under extreme conditions.

Durability

The heat-treated alloy steel construction withstands high torque, shock loads, and the constant vibration 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.

Compatibility

• Direct OE replacement, fully matching the dimensional, gear ratio, and mounting specifications of the original inter-axle differential.

Core Function

1. Torque Distribution: Splits engine torque between the front and rear drive axles for maximum traction.

2. Differential Action: Allows the two drive axles to rotate at different speeds, preventing drivetrain wind-up and tire wear.

3. Traction Optimization: Works with the vehicle’s traction control system to direct power to the axle with the most grip.
