Introducing Our Electric Drive Axle System

Cutting-edge Distributed Drive-by-wire System
Get in Touch

What is a Distributed Drive System?

Inspired by a forward-thinking design philosophy, we have embraced a lightweight, compact design approach for our EV drivetrain systems. 

The system adopts a dual-motor configuration, achieving a short transmission chain and lightweight design through wheel-side reducers, thereby enhancing transmission efficiency. The integrated design saves chassis space, allowing the battery to be positioned underneath. Wheel-side vector control technology further optimizes the vehicle's handling and maneuverability.

Our advanced technology and integrated systems guarantee that your vehicles achieve peak performance and reliability while optimizing efficiency and minimizing costs.

Distributed Drive-by-wire Systems

Up to 4 independent suspensions and 4-wheel drive. All four wheels can output torque in real-time according to demand, which provides greater stability and reliability for the vehicle.

High System Efficiency

By utilizing high power density tech, precise gear processing, and modular design, the system’s transmission efficiency reaches 98.6%. With a short transmission chain, this design effectively frees up chassis space, reduces system weight and decreases energy consumption by more than 15%.

Low-floor & Full Flat Design

Our battery cells are sourced from world-class manufacturers such as CATL, ensuring the highest quality and performance.

Safe & Less Maintanance

IP68, mature and reliable EDS(electronic differential), with tirechange mileage exceeding 100,000 kilometers ensuring high vehicle productivity and long lifespan, thus lowering TCO for the vehicle.

02. Electric Direct Drive System

  • PMSM Motor

    With a power range of 70 - 400 kW and a torque range of 500 - 5000 N.m, our e-powertrain solutions reduce operational costs and energy consumption for buses. The exceptional power performance of our electric motors ensures that buses perform reliably in high-frequency use and under frequent start-stop conditions, delivering safe, durable, and efficient power for long-term, dependable operation.

    electric-motor-for-bus

  • Motor with AMT

    The system features a lightweight, PMSM motor coaxially connected to an AMT, enabling smaller motors to match the performance of larger direct-drive units through torque amplification and speed adjustment. This design allows buses to handle gradients of 25% or more while significantly reducing weight—by up to 50%—and optimizing energy efficiency by keeping the motor within its high-efficiency operating range.

Successful Projects

  • 280 kWh High Voltage Battery Solution for Turkish Electric Bus

    Our client, a commercial vehicle manufacturer based in Turkey, has a wealth of experience in producing traditional diesel-powered buses. Driven by Turkey's environmental policies, they initiated a new project in 2022 to manufacture electric buses. 

    We successfully delivered seven sets of 280 kWh battery packs and developed the corresponding Battery Management System (BMS) and cooling systems. Currently, the 8-meter bus and 12-meter bus are undergoing normal testing and have obtained professional certification ECE R100 for mass production.

  • Electrification of Heavy-Duty Trucks and Drilling Equipment in Australia

    To support Australia's push for environmental sustainability, this project introduces 15-ton and 18-ton electric trucks and advanced electric drilling equipment tailored to local needs. Aimed at the mining, construction, and logistics sectors, these solutions help reduce carbon emissions, cut operating costs, and improve efficiency, highlighting the growing impact of electrification in heavy machinery.
