Leading the Way in Innovative Electric Powertrain Technologies

In the electrification of heavy-duty trucks, simply replacing the engine with an electric motor while maintaining the traditional central drive system of fuel trucks can lead to issues such as excessive weight, large size, and low efficiency. Our forward-thinking distributed electric truck axle offers a deeper optimization of the entire electric drive system, ensuring vehicle stability, safety, and efficiency.

With a robust portfolio of core technologies for e-powertrain design, including DCU, EASR, IESS, IRBS, and more, we are dedicated to delivering substantial benefits to heavy-duty trucks manufacturers, fleet operators, and drivers.

Strengthen Your Electric Truck Design

The distributed electric axle for heavy-duty truck significantly enhances the design of pure electric trucks. Through the distributed approach and compact integration, it boosts transmission efficiency and facilitates a more optimal vehicle layout.

Gas to electric heavy duty truck

Pure electric heavy duty truck

The pure electric trucks undergo a cabin redesign that lowers the center of gravity and minimizes aerodynamic drag.
Our electric truck axle ensures high transmission efficiency and enables more flexible space utilization.
The electric truck axle is seamlessly integrated into the chassis alongside the frame and battery pack, allowing for increased battery capacity and extendend range.

Building upon the positive design of the distributed electric drive system, further optimization of the structural design for pure electric heavy-duty truck chassis is achievable, enhancing space utilization rates. For instance, integrating our electric axle into the pure electric truck allows for the removal of the traditional drive shaft and enables the redesign of the frame structure to accommodate a flat arrangement of batteries within the chassis. This approach offers several benefits:

Enhanced power and range: placing batteries flat at the bottom maximizes power output, extends vehicle cruising range, and minimizes cargo volume occupation.
Improved stability: by adopting a box-shaped beam frame structure and housing the battery pack within it, the overall chassis structure becomes more stable, ensuring better vehicle stability and handling.
Lower center of gravity: with the battery pack positioned lower, the vehicle's center of gravity decreases, reducing the risk of rollover during turns and further enhancing driving stability and maneuverability.

Product Features

Brogen’s electric axle system for heavy-duty trucks features a dual-motor distributed drive scheme. This setup ensures complete independence between the left and right power systems. Each power system comprises a PMSM motor, a 2-speed AMT, and a wheel-side reducer. With the adoption of electronic differential technology, the left and right drive systems are independently controlled, enhancing overall performance and maneuverability.
