CASE STUDIES

HMMWV

ORBIS has identified the HMMWV M114 as a vehicle that benefits from decreased mass and increased payload that Ring-Drive technology can provide. As built, this vehicle is powered by a 6.5 liter V8 diesel engine, with all 4 wheels powered via an automatic transmission.

The HMMWV configuration creates several points of vulnerability where a single failed component can disable the entire vehicle, jeopardizing personnel and mission.

ORBIS technology as applied to the M114 eliminates the centralized drivetrain altogether, substituting four individually powered Ring-Drive wheels. The resulting vehicle is far more resistant to disabling events as each wheel is capable of independent operation. 

Each ORBIS Ring-Drive wheel is 50 hp, resulting in a total of 200 hp, compared to the 190 hp for the standard 6.5 diesel V8. ORBIS wheels weigh approximately the same as the standard HMMWV wheels, resulting in an ORBIS HMMWV battery-powered vehicle weighing approximately 1,000 lbs less.

In a hypothetical clean sheet HMMWV design, re-engineering can save another 150-250 lbs in curb weight. As the curb weight drops, the brakes and suspension can be redesigned to eliminate further mass, resulting in a more agile, efficient and less vulnerable vehicle.

 

An electrical control unit intelligently manages the ORBIS wheel motors, turning them on and off in support of vehicle performance and safety in high speed running, hill climbing and maneuvering control through twisting and low-traction routes. A further benefit of ORBIS’ Ring-Drive technology provides freedom from conventional a-arm, wishbone and other inner-pivot suspension designs. 

ORBIS Ring-Drive is especially suited to the emerging generation of autonomous combat and combat support vehicles now in development.
