Electric independent suspension concept from AxleTech
AxleTech's next-generation 5000 Series Electric Independent Suspension Axle System concept, the eISAS, features custom-designed electric motors as part of the axle. The concept acts as a complete electric powertrain system, reportedly eliminating the need for a traditional drivetrain, including engine, transmission, and gearboxes, which results in maintenance cost savings. 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 extenders (REV). In considering the modernization of military fleets, AxleTech’s 5000 Series eISAS concept reportedly enhances performance and can provide improved stealth characteristics, lower heat signatures, and improved fuel savings to logistics vehicles, tactical vehicles, and armored personnel carriers.
Along with offering the advantages of an independent suspension system, AxleTech’s 5000 Series eISAS concept can provide maximum regenerative braking capability. Additionally, once produced, the eISAS concept axle will use parallel axis gearing instead of traditional bevel gearing, which maintains the axle ground clearance and allows 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-pound (26.3 T) capacity, the company plans to develop similar powertrain concepts for lighter load vehicles as part of its strategy to electrify military and commercial applications. The production of these eISAS concepts will be based on customer demand for the technology.
