"Small, Cool, Powerful
Compact liquid-cooled electric drives help propel the latest generation of a heavy-duty military truck
Joseph Ogando, Senior Editor -- Design News, August 14, 2006
When the U.S. Army needs to move ammunition and other suppliescross-country, its soldiers often turn to a Heavy Expanded Mobility Tactical Truck, or HEMTT. These four-axle, diesel rigs can carry payloads of up to 13 tons off-road, on steep grades that look better suited for a tank. HEMTTs have little in common with their civilian trucks, except for one thing — they can both benefit from better gas mileage that doesn't come at the expense of power.
The HEMTT's maker, Oshkosh Truck Inc., went back to the drawing board three years ago to create a more fuel-efficient version of the truck, which it dubbed the HEMTT A3. Rather than trying to squeeze incremental improvements out of a conventional diesel engine, Oshkosh instead created a brand-new, hybrid-electric diesel powertrain. . . ."
What I like best is elimination of the mechanical drive train and the ultracapacitors are neat too! This is what I think the next generation hybrid electric should be.
With a 13 ton capacity, it should be able to carry:
- 15 'Fortwo' diesels suitably folded
- 10 TDI diesels suitably folded
. . .
This approach scales well!
