3. Advanced AMT Technology - Built for Smarter, Smoother Electric Trucks
This electric truck axle platform features a 4-speed AMT. It enables active speed synchronization between the motor and the transmission input shaft, allowing for rapid and smooth gear shifts. By combining gear profile modification with in-depth analysis of casing and shaft tooth deformation, the system achieves optimal meshing conditions, minimizing transmission error and reducing efficiency loss.
- Faster gear shifting: Reduced shift time improves drivability, especially under frequent stop-and-go scenarios.
- Higher drivetrain efficiency: Enhances energy use and supports longer driving range.
- Lower NVH: Quiet and smooth gear transitions improve driving comfort.
- Lower maintenance cost: Long-life gear oil with no initial oil chaange required; supports extended intervals of 50,000-200,000 km.
4. Key Performance Data
- Weight reduction vs. direct drive (dual axle): 22% per set
- Range improvement vs. direct drive: Up to 20%
- Energy use: 10% less per 100 km at 49t full load vs. industry average
