1.Product Description
The motor grader wheel drive axle assembly is a core transmission component for road construction and land leveling equipment. Designed to efficiently transfer power to the drive wheels, it ensures stable traction and precise control during asphalt paving, gravel leveling, and operations on complex terrain. Featuring a high-torsion-resistant structure, dynamic sealing technology, and multi-angle power transmission capability, it is engineered for high-frequency steering, heavy-duty scraping, and continuous vibration conditions, making it a critical component for efficient operation and long service life.
2. Product Features
(1) Heavy-Duty Torsion Resistance
Made from high-strength alloy steel through integral forging, surface hardening, and precision grinding processes.
Tensile strength ≥1,200 MPa, suitable for extreme blade loads and lateral forces in 12–30-ton motor graders.
(2)Dynamic Multi-Angle Power Transmission
Cross-type universal joint structure supports ±45° steering deflection.
Adapts to body posture adjustments during blade operation and dynamic wheel compensation on uneven terrain.
(3)Fully Sealed Contamination Protection
Multi-layer protection system (dust cover + fluororubber lip seal) with IP69K rating.
Resists asphalt adhesion, gravel splashing, and mud intrusion.
High-temperature grease (operating range: -40°C to 120°C) ensures extended maintenance intervals.
(4)Vibration Resistance & Lightweight Design
Optimized high-strength alloy material and structural design with surface hardening.
Fatigue life increased by 25%, suitable for continuous high-frequency vibration conditions.
