The Zero-8 e-Axles leverage Dana’s most robust and efficient drive axle technology, and are precisely engineered for demanding, over-the-road applications. The new e-Axle portfolio supports Dana’s approach to meet the diverse landscape of Class 7 and 8 EV architectures with multi-faceted electric powertrain solutions, including systems for direct drive and now 4×2, 6×2, and 6×4 multi-speed e-Axle systems.
The new e-Axles are designed to easily integrate into most existing chassis. The platform utilizes Dana’s vertically integrated and long-standing technologies, including Dana TM4™ motors and inverters, Spicer® high-efficiency axle gearing, Graziano® synchronizers, transmission controllers, system software, and shift system and controls.
The 4×2, 6×2, and 6×4 configurations are compatible with drum or disc brakes, and are available as completely integrated fully dressed assemblies. The e-Axles range from 52,000 Nm to 69,000 Nm of nominal output torque, and support gross axle weight ratings (GAWR) from 21,000 to 30,000 pounds for single e-Axle configurations, and 40,000 to 52,000 pounds for tandem e-Axle propulsion.
Additional distinct features of the system are its modular motor design that provides easy accessibility for servicing and maintenance, and a motor interchange capability for increased ease of scalability in the Class 7 and 8 application range, further accommodating customers’ electrified platforms.
With global production strategies underway, Dana has commitments from global OEM customers with deliveries beginning in late 2023.
