The EA3400N 11.5T distributed electric drive axle is designed for electric road passenger buses, tourism coaches and corporate commuter vehicles.
The EA3400N 11.5T distributed electric drive axle has been developed for commercial passenger transport applications, including road passenger buses, tourism coaches and corporate commuter vehicles.
The axle is designed to support electric bus platforms that require high torque output, low noise and vibration levels, and stable performance across long distance or high frequency operation.
The EA3400N has a rated load of 11.5 tonnes and a peak torque of 34,000 Nm. These specifications position the axle for medium and heavy duty electric bus and coach applications where acceleration, hill climbing ability and passenger comfort are important operating factors.
The system includes electronic drive anti slip control and Electronic Stability Control, ESC, to support vehicle stability during operation on highways, gradients and variable road conditions.
The supplier also highlights NVH performance as a key design focus. Reduced noise and vibration are particularly relevant for passenger buses and coaches, where drivetrain refinement affects ride comfort during longer journeys.
According to the company, more than 500 road passenger coaches equipped with this axle have entered operation across more than 10 cities. The supplier also reports that individual vehicles have reached more than 80,000 km of operation in applications including tourism transport and corporate commuting.
The company states that operating feedback shows lower energy cost per kilometre compared with conventional fuel coach applications. These figures should be evaluated according to local energy prices, route profile, payload, duty cycle and air conditioning use.
For OEMs and fleet operators, distributed electric drive axles can support electrification strategies by integrating propulsion into the axle architecture. This can reduce dependence on conventional driveline layouts and improve packaging flexibility for electric bus platforms.
