The EA2100N 13T distributed wheel side motor axle supports low floor electric buses with integrated drive functions, regenerative braking, ESC and ECE certification.
The EA2100N 13T distributed wheel side motor axle has been developed as an electric drive axle solution for low floor electric transit vehicles.
The axle is designed for use in 10 metre and above new energy city buses, 18 metre articulated buses, airport shuttle buses, double decker sightseeing buses and commuter coaches. Its distributed wheel side motor configuration integrates drive, transmission, suspension and braking functions, reducing reliance on conventional powertrain components such as the engine, transmission and drive shaft.
The system delivers peak power of 2 x 160 kW, motor peak torque of 2 x 580 Nm and maximum system output torque of 21,552 Nm. It has a maximum speed of 8,000 rpm and an IP68 protection rating, supporting operation in demanding road and weather conditions.
The axle uses a modular architecture and parallel shaft cylindrical gear transmission. According to the company, the design reduces weight by around 100 kg compared with direct drive configurations, helping improve vehicle payload and energy efficiency.
A key application benefit is support for full flat low floor bus layouts. This can improve passenger accessibility, increase standing area and support safer passenger movement inside the vehicle, particularly for elderly passengers, passengers with strollers and people with reduced mobility.
The EA2100N also includes safety and efficiency functions such as electronic stability control, intelligent regenerative braking and electronic differential control. The regenerative braking system is designed to support energy recovery across operating conditions, while the electronic differential helps reduce tire slip and tire wear.
The axle has received ECE certification and has been exported in bulk to markets across Europe and the United States. The company reports single vehicle operating mileage exceeding 300,000 km, failure free mileage of 150,000 km and cumulative fleet operation mileage in the tens of millions of kilometres.
For electric bus OEMs and transit operators, the EA2100N reflects the continued development of integrated e axle systems for low floor, high capacity and energy efficient public transport vehicles.
