AxleTech has unveiled a new electric vehicle powertrain system with independent suspension. The next-generation 5000 Series Electric Independent Suspension Axle System (eISAS) concept was unveiled at Eurosatory 2018, an international defense and security exhibition in Paris, France.
Incorporating custom-designed electric motors as part of the axle, the concept acts as a complete electric powertrain system, eliminating the need for a traditional drivetrain, including engine, transmission, and gearboxes, AxleTech said. The system is engineered for full battery electric vehicles (BEV), fuel cell range extender electric vehicles (FCEV) and internal combustion engine (ICE) or turbine generator range extender vehicles (REV).
In terms of military applications, AxleTech said the 5000 Series eISAS concept enhances performance and has the ability to provide improved stealth characteristics, reduced heat signatures and improved fuel savings to logistics vehicles, tactical vehicles and armored personnel carriers.
“Our team is relentless in identifying ways to improve our products and technology to benefit customers,” said Bob Nichols, senior manager, Sales, Electric Vehicle Systems at AxleTech. “The 5000 Series eISAS is an example of this mindset – we look forward to working with customers to customize it for future applications.”
Along with offering the advantages of an independent suspension system, AxleTech said the 5000 Series eISAS concept offers a superior electric solution. Unlike standard axles, the new concept will provide maximum regenerative braking capability, which allows the energy from braking to recharge the vehicle’s batteries, along with improved efficiencies. Additionally, once produced, the eISAS concept axle will utilize parallel axis gearing instead of traditional bevel gearing, thereby maintaining the axle ground clearance and allowing for maximum torque to the wheels.
While the 5000 Series eISAS concept is intended to be a highly efficient solution for future vehicles with a gross combination weight rating (GCWR) up to 58,000 lb. (26.3 ton) capacity, AxleTech plans to develop similar powertrain concepts for lighter load vehicles as part of its strategy to electrify military and commercial applications. The production of the eISAS concepts will be based on customer demand for the technology.
