- Wanliyang heavy-duty truck eAxle completes successful prototype testing.
- Prototype showcases integrated electric drivetrain for commercial transport.
Zhejiang Wanliyang Co Ltd has announced the successful completion of prototype production for its first independently developed electric drive axle designed for heavy-duty trucks. The new A11S200-3E380 has also passed assembly-level bench testing, marking an important milestone in the company's commercial vehicle electrification program. The prototype demonstrates Wanliyang's progress in developing integrated electric driveline solutions intended to meet the performance and durability requirements of modern heavy-duty transportation.
Designed for 6×4 Heavy-Duty Truck Applications
The A11S200-3E380 is engineered specifically for 6×4 heavy-duty truck tractors and carries a rated axle load capacity of 11.5 tons. Its integrated architecture combines a hairpin oil-cooled electric motor with a three-speed automatic transmission, creating a compact electric drive system. According to the disclosed specifications, the motor produces a peak output of 300 kW, while maximum wheel-end torque reaches 38,000 N·m, providing the performance required for demanding commercial vehicle operations.
Integrated Design Enhances Performance and Lubrication
The electric drive axle incorporates a high-strength cast axle housing to support durability under heavy operating conditions. It is also equipped with an intelligent electric oil pump that adaptively adjusts lubrication flow according to operating requirements, helping optimize lubrication efficiency. This integrated configuration combines power delivery, transmission, and lubrication technologies into a single solution developed for heavy-duty electric truck applications.
