Electric Semi-Truck
Electric Axles for Trucks
As heavy-duty trucks accelerate toward electrification, drivetrain architecture has become a key determinant of performance, efficiency, and platform scalability. Electric axles for trucks integrate the traction motor, transmission, and drive axle into a compact, high-efficiency system—replacing traditional motor, driveshaft, and axle layouts.
We offer a comprehensive range of electric axle solutions for trucks, covering both centralized drive e-axle and distributed drive e-axle architectures. Designed for diverse truck platforms and duty cycles, our eAxle systems deliver high torque density, strong efficiency, and flexible integration. Most solutions are already in mass production and globally deployed, providing OEMs with a proven, production-ready foundation for electric heavy-duty vehicles.

Strengthening Your Electric Truck Platform Design
Electric axles enable a fundamental shift from diesel-based or retrofit electric truck architectures to purpose-built electric platforms. By eliminating the central driveshaft and consolidating the drivetrain into the axle, electric axle systems unlock new possibilities for chassis layout optimization.
Typical Gas-to-electric heavy duty truck
- The tapered cabin structure of the gas-to-electric heavy truck has higher aerodynamic drag.
- The rear-mounted battery box occupies cargo space, limiting both the available space and the vehicle's range.
- The chassis space utilization is suboptimal, leading to inefficiencies in transmission.
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.
- 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.

Frequently Asked Questions
Electric axles are best suited for truck platforms where chassis packaging, drivetrain efficiency, and system simplification are key design objectives. They can be applied in electric semi-trucks, tractors, tippers, municipal vehicles, and electric trailers, especially when flat battery layout, lower center of gravity, or reduced mechanical complexity is required.
Yes. Our electric axle solutions are platform-based but configurable, allowing customization of key parameters such as motor power, voltage level, and control strategy.
For projects aligned with our existing platforms, customization can be achieved with limited development effort, reducing project risk and timeline.
Compared to traditional central-drive layouts, electric axles significantly reduce vehicle integration complexity by eliminating the driveshaft and consolidating powertrain interfaces. OEM involvement typically focuses on suspension integration, mounting interface definition, cooling routing, adn vehicle-level calibration.
Most of our electric axle solutions are already in mass production and deployed globally. The architectures, key components, and control strategies have been validated through bench testing, vehicle testing, and long-term real-world operation, making them suitable for series-production projects rather than prototype-only projects.
Our electric axles for trucks are engineered for high axle loads, frequent start-stop cycles, and demanding environments such as ports, construction sites, and mining operations. Architecture selection (centralized vs. distributed drive) allows optimization for torque delivery, redundancy, and thermal robustness under heavy-duty duty cycles.
Compared with conventional motor + driveshaft + axle layouts, electric axles enable better packaging, lower system complexity, and improved efficiency, particularly on purpose-built electric truck platforms. The benefits become more pronounced as vehicle electrification levels increase and platform integration deepens.
To evaluate suitability, we typically require information on axle load rating, target torque and power, duty cycle, vehicle mass, voltage platform, and packaging constraints. Based on this, we can propose an appropriate electric axle architecture and configuration.
