HDE11.5t Oil-Cooled Single-Motor Two-Stage Electric Drive Axle: A Game-Changer for New Energy Commercial Vehicles
The HDE11.5t oil-cooled single-motor two-stage electric drive axle is a key product launched by HanDe Axle for the new energy commercial vehicle market. Specifically designed for GCW ≤49t 6×4 tractors, the product boasts the following features:
- High Torque: Maximum output torque (single motor) of 38,000Nm.
- High Efficiency: The motor’s power density is 6kW/kg, with a 4-6% increase in transmission efficiency. The 800V controller enables fast charging, improving overall vehicle operational efficiency.
- Lightweight: The integrated design combines the motor, electronic control system, and transmission, reducing weight by over 200kg compared to similar market products.
- Long Maintenance-Free Period: The axle requires minimal maintenance, with the first oil change at 300,000/600,000 kilometers, and the wheel end is maintenance-free for the lifetime of the vehicle.
The oil-cooled system used in this axle offers superior heat dissipation compared to traditional water-cooled systems, ensuring stable motor performance even under high power operations. Additionally, the integrated flat-wire motor has a higher slot filling rate and greater power density than conventional round-wire motors, effectively enhancing vehicle operation efficiency.
