Allison Transmission is introducing the AXE Series, a fully integrated electric powertrain system designed to fit inside a standard frame along the axles of commercial trucks. The AXE Series features electric motors, a two-speed gearbox, oil coolers and pumps. The offering also includes power electronics for a complete powertrain solution.
The electric powertrain will be integrated in Peterbilt’s Model 579EV electric Class 8 truck for evaluation and testing. As a result, the truck features 1,475 horsepower (1,100 kilowatts), delivering industry-leading performance as well as efficiency.
“With our more than 100 years of being an innovation leader, Allison is leading the transformation of the commercial vehicle industry with electric powertrain solutions,” said David S. Graziosi, Allison Transmission president and CEO. “The AXE Series is the first e-axle in the heavy-duty truck industry to provide this level of power density, size and simplicity. We take tremendous pride that our solution is one of the most efficient and powerful systems ever to be developed for commercial trucks.”
The Allison AXE Series has a one million-mile design life for medium- and heavy-duty trucks. The system integrates one or two high-speed electric motors and a multi-speed transmission, eliminating the need for additional driveshafts and support structures. A dual-motor axle has a continuous power of 536 hp (400 kW) and peak output power of 738 hp (550 kW). A tandem axle configuration is also available for these vehicles. The system can handle 100 percent torque in regenerative braking. The complete integration of the AXE Series delivers increased efficiency and best-in-class continuous power through superior internal cooling.
The AXE Series is available in single and dual motor options to package the entire electric powertrain inside a standard frame that exists in almost every global commercial truck. This allows the AXE Series to be a bolt-in solution by design, ensuring efficiency in the installation process.
