1.Product Description
The Loader Wheel Drive Axle Assembly is a core component of engineering machinery power transmission, specifically designed for heavy-duty loading, high-frequency impacts, and complex terrain operations. It efficiently transfers power to the drive wheels, ensuring stability and reliability during material handling, slope climbing, steering, and multi-condition switching. Featuring a high-strength anti-torsion structure, dynamic sealing technology, and fatigue-resistant design, it is tailored for extreme working conditions in mining, ports, and construction sites, serving as a critical component for efficient operation and long service life of loaders.
2.Product Features
(1) Ultra-Strong Anti-Torsion Design
Made of high-strength alloy steel through integral forging and surface hardening, with a tensile strength ≥1,200 MPa. Suitable for heavy-duty shoveling and material dumping impacts of 3–10-ton loaders.
(2)Multi-Directional Dynamic Compensation
Cross-type universal joint structure supports ±45° steering deflection, accommodating dynamic displacement caused by uneven ground wheel bouncing and uneven bucket loads.
(3) All-Weather Sealing Protection
Multi-layer redundant sealing system (dust cover + fluororubber lip seal) with IP68/IP69K protection rating, resistant to mud, dust, salt spray, and high-pressure water washing. Long-lasting high-temperature grease (operating temperature: -40°C to 120°C) ensures extended maintenance intervals.
