The modular electric drive axle - compact, safe, and reliable
We offer electric bus axles with system power ranging from 60 kW to 320 kW, making them suitable for battery electric buses and hybrid buses from 5 to 18 meters. Our electric axle for bus integrates one or two motors, providing ample drive power for these vehicles. With our advanced design strategy, we ensure the safety and reliability of our electric drive axle systems.
Customized eAxle Systems
We have extensive experience manufacturing and supplying electric axles to EV manufacturers worldwide. Our e-axle systems have been widely deployed in city buses, coaches, and shuttle buses across Europe, Southeast Asia, and many other regions.
Wide Applications
We offer a complete range of electric bus axles suitable for buses from 5 meters to 18 meters, including rail metros.
Scalable
Our modular e-axles support high voltage platforms and can be customized to meet specific requirements of our customers.
Reliable
We implement advanced monitoring and alerting strategies to esnure the safety and reliability of our electric drive axles for public transport.
Versatile
We provide electric drive systems with different approaches such as distributed drive, central drive, etc., catering to diverse needs.
Solutions
Coaxial Electric Drive Axle
Designed for pure electric buses, this coaxial electric drive axle system integrates the motor and drive axle into a single unit. The motor is arranged coaxially with the axle housing, resulting in a more compact structure and a highly concentrated power system. This design optimizes the chassis layout, reduces weight, increases transmission efficiency, lowers energy consumption, extends range, and enhances the reliability of the motor and core transmission components.
Example configurations:
- For 6-meter buses: 2.2 T front steering axle + 3.5 T electric rear axle
- For 7.5-meter buses: 3.5 T front steering axle + 5.5 T electric rear axle
- For 9-meter buses: 5.5 T front steering axle + 8.5 T electric rear axle
- Smallest chassis footprint in the industry
- High-precision cylindrical helical gear transmission
Solutions
Parallel-Axis Electric Drive Axle
The motor and reducer are mounted on the drive axle, with the motor positioned parallel to the axle housing. Utilizing cylindrical gear transmission for a high gear ratio, the integrated design removes unnecessary transmission components, resulting in a more compact structre and increased transmission efficiency.
Example configurations:
- For 6-meter buses: 3.5 T 120 kW electric drive axle
- Achieved mass deployment
- Integrated multi-speed, multi-motor system
Solutions
Distributed Electric Drive Axle
In this system, we have integrated two electric motors with the axle, significantly reducing system weight and enhancing vehicle power efficiency. The distributed approach provides additional safety redundancy: in the event of a single motor failure, the remaining motor can compensate, ensuring continuous power delivery and improving overall vehicle safety.
Example configurations:
- For 8-meter buses: 9 T 240 kW electric drive axle
- For 12-meter buses: 13 T 320 kW electric drive axle
- Low-floor design, extra-wide aisle
- 20% lighter than direct drive system
- Extra safety redundancy
