Dana is adding electric axles for Class 7 and 8 applications and will begin production of electric axles for Freightliner Custom Chassis medium-duty delivery vehicles this fall.

At the Aug. 31 ACT Expo in Long Beach, Calif., Dana officials highlighted the large number of utility vehicles using Dana components, such as International, Lion Electric, XO and Lonestar Specialty Vehicles. This includes parts such as electric motors, inverters and on-board loads, as well as more traditional products such as axles and drive shafts.

The new electric axle portfolio supports Dana’s approach to addressing the diverse landscape of Class 7 and 8 electric vehicle architectures with multi-faceted electric powertrain solutions, including direct drive systems and now multi-speed electric axles 4×2, 6×2 and 6×4 systems.

The new electric axles are designed to fit easily into most existing chassis. The platform utilizes Dana’s longstanding, vertically integrated technologies, including Dana TM4 motors and inverters, Spicer high-efficiency axle gears, Graziano synchronizers, transmission controllers, system software and system and shift controls.

4×2, 6×2, and 6×4 configurations are compatible with drum or disc brakes and are available as fully-integrated, fully-dressed sets. Electric axles range from 52,000 Nm to 69,000 Nm of rated output torque and support gross axle weight ratings of 21,000 to 30,000 pounds for single electric axle configurations and 40,000 to 52,000 pounds for tandem electric axle propulsion.

A modular motor design provides easy access for service and maintenance. A motor swap capability will allow for increased scalability across the range of Class 7 and 8 applications.

The new electric axles are currently being tested worldwide in battery electric and fuel cell applications. Global production strategies are underway and Dana said it has commitments from global OEM customers with deliveries beginning in late 2023.

Production of electric axles for FCCC

Dana also announced that it will begin production of its e-Axle eS9000r, the first in a line of Spicer Electrified Zero-6 e-Axles, to support the market launch of the all-electric Freightliner Custom Chassis Corporation MT50e at average use of the last mile delivery vehicle.

Designed with a custom Spicer S130 rear drive axle, the propulsion system for the MT50e application is designed as a fully integrated electric axle, including gearbox and motor, providing up to 240 kW of power to support the range of the vehicle up to 170 miles.

The Zero-6 e-Axles fit efficiently into the all-electric FCCC MT50e chassis, streamlining the electronic propulsion system, which is designed with full charge capability in approximately three hours using DC fast charging. Dana’s patented electronically controlled parking pawl system is also included in the power axle design.
