AxTrax 2
Electric axle for medium- and heavy-duty commercial vehicle (CV) applications
Key Facts
Higher CapabilitySupports up to 28 t GCW and 13 t axle loadEnhanced TorqueUp to 34,400 Nm850 V ReadyEnables compatibility with future vehicle architectures
This e-axle is designed to replace engine, transmission, and conventional axle to electrify a commercial vehicle. ZF’s modular platform approach integrates in-house developed components into an innovative axle-based one-box solution with compact size and light weight, and a packaging fitting into the space of the conventional axle, while providing high power and torque, at enhanced efficiency. Furthermore, the minimized space requirements enable OEMs to reimagine the design of CV platforms.
