At the Advanced Clean Technology (ACT) Expo, Allison Transmission, a company specializing in medium- and heavy-duty propulsion solutions for commercial vehicles, introduced the AXE Series, an e-axle system for medium and heavy duty trucks. 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 2-speed gearbox, oil coolers, and pumps. The offering also includes power electronics for a complete powertrain solution.

“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, a 2019 Automotive News PACE Award finalist, 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 horsepower (400 kilowatts) and peak output power of 738 horsepower (550 kilowatts). 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 continuous power through 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, including refuse trucks, school buses, and drayage and delivery trucks. This allows the AXE Series to be a bolt-in solution by design, ensuring efficiency in the installation process.
