In a typical car with gears, you tend to lose about 15% of your power through the drive train on a 2wd vehicle. It approaches 30% with a 4wd vehicle. Since this is based on a diesel vehicle, I imagine it won't be too far off. Maybe worse because of the huge size of everything, but I'm not a mechanical engineer.
- jaclaz 9y agoThough it is not - I believe - the case of this specific Komatsu model, electric driven dumper trucks are in production, getting rid of the transmission, examples, JFYI: http://www.komatsuamerica.com/equipment/trucks/electric http://www.komatsuamerica.com/equipment/trucks/electric http://www.cat.com/en_ID/products/new/equipment/off-highway-trucks/mining-trucks/18232553.html# http://www.cat.com/en_ID/products/new/equipment/off-highway-... Basically this kind of trucks have a huge diesel engine and electric generator and four electric motors, one for each wheel. Power is lost in the generation and powering of the electric motors of course, but there is no transmission overhead (though there is a reduction gearbox on each motor anyway).
