Eurosatory 2018

Cut out the engine [ES18D3]

13 June 2018

An innovative powertrain system from AxleTech Systems (Hall 5A, Stand B648) was unveiled at Eurosatory this week. Combining its expertise in electric vehicle powertrain systems and independent suspension technologies, AxleTech developed the next-generation 5000 Series electric Independent Suspension Axle System concept, which it calls eISAS.

eISAS features custom-designed electric motors as part of the axle, thus becoming a complete electric powertrain system that eliminates the traditional drivetrain, including engine, transmission and gearboxes, which has obvious cost savings. The system provides for full battery electric vehicles, fuel-cell range extender electric vehicles and internal combustion engine or turbine generator range extenders.

For military operators, this technology has the benefit of improved stealth, lower heat signatures and fuel savings.

According to the company, the concept will allow for the energy from braking to recharge the vehicle’s batteries. The eISAS concept axle will also utilise parallel axis gearing instead of traditional bevel gearing, thus maintaining the axle ground clearance and allowing for maximum torque to the wheels.

Currently, the concept is intended for future vehicles with a gross combination weight rating of up to 26 tonnes.

AxleTech is considering similar concepts for lighter load vehicles for military and commercial applications.
