The BRIST Corner Drive e-Axle is a game-changer for the city-bus segment, providing a powerful means for impactful and value added differentiation in an increasingly competitive market.
Its patented design features a high-speed 750 VDC hairpin winding motor, with an optimized layout that accommodates more powerful motors. The motors are housed in a ventilated area, separate from the gears, ensuring optimal cooling.
The e-Axle’s compact and modular design maximizes space efficiency, allowing for better utilization of battery modules.
Additionally, it offers up to 400 kg in system weight savings, resulting in 2-8% energy savings for the vehicle. The reduction in unsprung mass is significant, with up to 700 kg less weight, thereby enhancing vehicle dynamics.
Lastly, the BRIST eCOR electric axle offers significant serviceability advantages, providing individual access to the motor, gearbox, and axle—unlike competitor concepts, which integrate all components in a closed environment.
Furthermore, an optional all-wheel steering system is available for trackless trams and bidirectional autonomous shuttles, further increasing the system’s versatility.
