Product Description
High Precision Forged Inter-wheel Differential Flange Hub HD91129320044 | Heavy Truck Drive Axle Differential Core Component
Product Description
This HD91129320044 inter-wheel differential housing is the core power distribution part of heavy truck drive axle. Manufactured via integral precision forging from high-strength alloy steel, inner bore adopts precision broached internal spline structure, outer flange pre-drilled with evenly distributed standard mounting holes per OEM blueprint. Each finished piece undergoes metallurgical hardness inspection and dimensional precision testing to ensure stable torque split between left and right drive wheels under full-load climbing & cornering conditions.
Technical specifications
| Feature | Specification | Benefit |
|---|---|---|
| Raw Material | High strength alloy steel integral forging | Anti-impact & anti-fatigue for heavy haul harsh working |
| Inner Structure | Precision broached internal involute spline | Close meshing with half shaft, stable power transmission |
| Flange Layout | Evenly spaced OEM standard mounting holes | Uniform fastening force to prevent housing distortion |
| Machining Craft | Fine finish turning & broaching | Stable size accuracy against long-time alternating load |
Key Features | Core Advantages
- High-grade alloy steel forging greatly improves impact resistance and anti-fatigue performance under heavy cargo load.
- Precision machined inner involute spline realizes tight meshing with half shaft spline, avoiding power skidding and abnormal noise.
- Uniformly distributed flange mounting holes ensure even bolt fastening stress, preventing housing deformation during long-term operation.
- Strict finish machining eliminates internal residual stress to keep stable dimensional accuracy under alternating axle load.
- OEM consistent spline tooth count, hole circle diameter and overall dimension support direct aftermarket replacement.
