Differential Of Middle Axle AZ9231320745 Sinotruk

Product Introduction

This middle axle differential assembly is a heavy-duty, fully integrated unit, specifically engineered for multi-axle heavy-duty truck applications. It is constructed from high-strength cast iron and alloy steel, featuring a robust housing, precision-forged spiral bevel gears, and a complete inter-axle differential mechanism. The assembly includes the main reduction gear set, differential case, side gears, pinion gears, and an integrated differential lock mechanism, all pre-assembled and pre-adjusted to OE specifications. The gear teeth are precision-cut and carburized for exceptional wear resistance, while the housing is designed to withstand the high torque loads and dynamic stresses of multi-axle operation. Precision-machined mounting surfaces, oil passages, and a differential lock actuator ensure proper lubrication, alignment, and on-demand locking functionality, making it suitable for the demanding conditions of long-haul and heavy-load transportation.

Core Function

• Reduces the high-speed, low-torque input from the transmission to the low-speed, high-torque output required for driving the wheels.

• Distributes torque between the middle and rear axles, allowing them to rotate at different speeds to compensate for differences in tire wear and road conditions, preventing drivetrain binding.

• The integrated differential lock mechanism can be engaged to lock the middle and rear axles together, providing maximum traction in low-friction or off-road conditions.
