60kW / 130kW Coaxial Electric Axle
Our 60 kW / 130 kW coaxial electric axle is ideal for light trucks from 4.5-ton to 6-ton or electric vans and buses from 5 meters to 6 meters. With its lightweight design, low noise levels, and high transmission efficiency, it ensures a smooth and comfortable driving experience for drivers and a quiet, enjoyable ride for passengers. Compared to traditional direct-drive systems, this electric bus axle assembly reduces overall weight by more than 100 kg and largely decreases energy consumption. Electric buses with this e-axle have been exported to Japan, Australia, and Europe.

Technical Benefits of the Coaxial Electric Axle
Central Direct Drive Motor
Minimal modification to existing internal combustion engine (ICE) platforms. The electric motor replaces the engine, with power transmitted to the rear axle through a driveshaft.
- Low-cost integration and easy comprability with existing vehicle architectures.
- The need for a driveshaft and traditional rear axle reduces chassis space and limits battery placement, decreasing overall range.
Parallel-Axis E-Axle
A more compact electric powertrain design for commercial vehicles. The motor is integrated directly into the rear axle, eliminating the driveshaft and creating additional space for battery placement.
- Simpler structure with fewer parts, improved space for batteries, and better range.
- The motor's off-center weight distribution led to vibration issues, and NVH performance become a challenge due to the unique design.
Coaxial E-Axle
In this electric powertrain system, both the electric drive motor and output shaft are aligned along the same axis, allowing for a more compact, stable, and efficient design, helping improve overall layout.
- Improved rotational stability, reducing vibrations and enhancing noise control.
- Weight reduction and space optimization with the motor housing serving as a load-bearing element.
- Increased system efficiency due to the elimination of high-speed bearings and a more direct power transfer.
- Superior NVH performance, with reduced center-of-gravity offset and less vibration.
