AxTrax2 LF is ZF's latest addition to its in-house developed suite of e-drives specifically designed for city and intercity buses up to 30 tons. With a space-efficient design using similar installation space as the previous low-floor e-axle, it allows for simple interchangeability with existing electric vehicle setups. The innovative solution comprises two stand-alone silicon carbide (SiC) inverters and an ECU, creating a comprehensive e-axle system for electric, hybrid, and trolley buses.
