Function, Specifications, Materials, and Key Parameters of
DZ90149320000 Differential Assembly
1. Function
The DZ90149320000 differential assembly is a critical component in
the vehicle's drivetrain system, designed to distribute torque
between the two half-shafts (axle shafts) while allowing them to
rotate at different speeds. This enables the vehicle's wheels to
maintain traction and roll smoothly, especially during turns, by
reducing tire wear and friction with the ground.
2. Specifications
• Part Number: DZ90149320000
• Brand: Hande Axle
• Model: Specifically designed for use in medium and heavy-duty
commercial vehicles, such as the Shaanxi Automobile Delong series
(e.g., M3000, X3000)
• Type: Inter-axle differential assembly for the central drive axle
• Configuration: Often includes a twelve-claw design , which refers
to the number of teeth or claws on the differential gears
3. Materials
• Gear Housing: Constructed from high-strength alloy steel to
withstand high torque and impact loads
• Gears: Made from high-quality alloy steel with precision
machining to ensure smooth operation and durability
• Bearings: Use high-precision ball bearings or tapered roller
bearings to support the rotating components and reduce friction
• Seals: Made from rubber or polyurethane to prevent lubricant
leakage and contamination
4. Key Parameters
• Rated Torque: Designed to handle specific torque levels based on
the vehicle's powertrain requirements (specific value not provided,
but typically ranges from 10,000 Nm to 30,000 Nm for commercial
vehicle applications)
• Gear Ratio: The ratio between the input and output speeds of the
differential, which determines the torque distribution and
vehicle's driving characteristics (specific value not provided, but
optimized for the vehicle's performance)
• Weight: The weight of the differential assembly may vary based on
materials and design, but it is typically heavy-duty to ensure
reliability (specific value not provided, but generally designed to
be robust)
• Operating Temperature Range: Designed to operate effectively in
various environmental conditions (specific value not provided, but
typically designed to operate between -40°C and +120°C)
• Lubrication: Requires specific lubricants to ensure smooth
operation and longevity (type and viscosity not provided, but
typically industrial gear oils are used)
• Mounting Type: Designed for easy mounting on the vehicle's drive
axle, with specific mounting holes and brackets for secure
attachment
• Compatibility: Designed to be compatible with specific vehicle
models and powertrain configurations (e.g., compatible with Hande
axles and Shaanxi Automobile Delong series trucks)
