1.Product Description
The bulldozer wheel-end drive axle assembly is a core transmission component for earthmoving equipment, specifically designed for bulldozers operating in harsh terrains, heavy-duty pushing, and continuous impact conditions. It efficiently transmits power to the drive wheel group, ensuring traction and stability during excavation, land leveling, and complex terrain operations. Featuring an ultra-high-strength torsion-resistant structure, dynamic sealing technology, and impact-resistant optimization, it is tailored for extreme applications such as mining stripping, road construction, and disaster relief. This assembly is a critical component for ensuring bulldozer efficiency and long service life.
2. Product Features
(1) Ultra-Strong Torsion & Impact Resistance
Forged from special alloy steel with surface hardening treatment, tensile strength ≥1,200 MPa, suitable for high-impact operations like heavy-duty pushing and hard rock stripping in 20~50-ton bulldozers.
(2) Multi-Directional Dynamic Compensation Structure
Cross-shaft quasi-constant velocity universal joint design allows ±45° steering deflection, adapting to wheel group bouncing and chassis posture adjustments on rough terrain, eliminating power transmission gaps.
(3) Fully Enclosed Protection System
Multi-layer sealing (dust cover + fluororubber lip seal) with IP69K rating, resisting mud, gravel, high-pressure water jets, and corrosive soil intrusion. High-temperature grease (operating range: -40°C to 120°C) ensures extended maintenance intervals.
(4) Vibration Resistance & Lightweight Optimization
High-strength alloy material with structural optimization and surface hardening, improving fatigue life by 30%, suitable for continuous high-frequency vibration and impact loads.
3. Product Specifications

| Certifications | ISO 9001, CE, GB/T 9139 (construction machinery strength standard), ISO 3457 (sealing performance certification) |
4. Application Scenarios
(1) Mining Stripping Operations: Withstands hard rock impacts, high-frequency vibrations, and overloaded pushing.
(2) Road Construction & Maintenance: Adapts to continuous asphalt paving, gravel backfilling, and complex terrain steering.
(3) Disaster Relief Cleanup: Mud-proof sealing ensures reliable performance in floods, landslides, and other harsh environments.
(4) Frozen Soil Zone Construction: Ultra-low-temperature grease version supports stable operation in -50°C extreme cold.
(5) Port Land Reclamation Projects: Salt spray-resistant coating protects against seawater and high-humidity corrosion.
5.Product Advantages
(1) Durability: Reinforced flange and spline shaft design withstands mining overloads and instant impact loads.
(2) Quick Maintenance Design: Modular split structure enables on-site replacement in ≤35 minutes.
(3) Environmental Adaptability: Optional acid-resistant coating (for chemical waste handling) or explosion-proof version (for oil/gas mining zones).
(4) Energy Efficiency Optimization: Transmission efficiency ≥98%, reducing energy loss and improving fuel economy or electric bulldozer range.
