DZ90149320005 Differential Carrier Assembly
1. Function
• Power Distribution and Speed Differential: The differential carrier assembly is installed in the drive axle to distribute power from the drive shaft to the left and right half-shafts while allowing them to rotate at different speeds. This enables the wheels on both sides to roll at different speeds when the vehicle is turning, reducing tire wear and ensuring smooth turning.
• Reducing Tire Friction: By allowing the left and right wheels to rotate at different speeds, the differential minimizes the sliding friction between the tires and the ground, improving driving stability and comfort.
• Torque Transfer: In four-wheel drive vehicles, the differential lock can quickly engage when one drive axle slips, transferring torque to the non-slipping drive axle to enhance traction and help the vehicle escape from difficult terrain.
2. Specifications
• Part Number: DZ90149320005
• Application: Specifically designed for the intermediate axle of SHACMAN Delong trucks (e.g., HDZ300 model).
• Brand: Shaanxi Hande Axle
• Type: Middle axle differential carrier
• Installation Position: Intermediate axle
• Compatible Models: SHACMAN Delong series trucks
3. Material
• Differential Carrier Housing: Typically made of cast iron or aluminum alloy. Cast iron, especially nodular cast iron (e.g., QT420-10), is widely used due to its good strength, plasticity, toughness, and cost-effectiveness. Aluminum alloy is also an option, offering lower density, comparable strength to gray cast iron, higher toughness, and better casting performance, which helps reduce weight and improve heat dissipation.
• Internal Components: Gears, shafts, and bearings are usually made of high-strength alloy steel to withstand high torque and friction.
4. Key Parameters
• Gear Ratio: The differential carrier may have a specific gear ratio (e.g., 4.769), which affects the vehicle's torque output and speed.
• Maximum Torque: The differential must be able to withstand the maximum torque output of the engine to ensure reliable power transmission.
• Bearing Capacity: The differential carrier should have sufficient bearing capacity to support the weight of the vehicle and the forces generated during driving.
• Weight: The weight of the differential carrier assembly varies depending on the material and design, typically ranging from a few tens to over a hundred kilograms.
• Dimensional Accuracy: Precise dimensions are critical to ensure proper fitment with other drive axle components, such as the half-shafts and drive shaft.
• Operating Temperature Range: The differential must operate reliably within a specified temperature range to accommodate different environmental conditions and heat generated during operation.
