Very interesting news from Belarus at the Agritechnica:
Belarus 3023
The 220 kW standard tractor has a diesel-electric drive with modern control electronics and good efficiency levels. The front pto is powered electrically and its rpm speed is thus largely independent of the internal combustion engine. Up to 172 kW electric power can be passed on from the internal DC high voltage network to external users that display corresponding power requirements.

I am saying for a couple of years, that diesel-electric drive has the future, not hydromechanic vario. Even though others have taken small steps into this direction, it just surprises me that Belarus is the one to just jump right into it with a production model.  |

did you know a 1/4 of all scientific literature wrote in the world is in russian
what belarus is up to don't suprise me at all

bring it on..
How would an electric motor handle prolonged high loads at low speed?

I really don't know too much about the technology, but if multi thousand hp trains can be powered via diesel electric, and if we have nanotechnology available, surely we can split the middle and produce 100 - 400 hp tractors using diesel electric

Hey
Discussion about electric drive is old thing.
Is clear that some solution is coming later or sooner also to tractors.
I have worked with el.drives and if i understand main problem in tractor transmission for el.system is lage ratio.Low speed need big torque with low rounding speed.Other end of scale lot speed is needed with low torque.
Seems to me that this moment still el.drive cannot work better as stepless.
Still i believe that some day el.drive is working.

This combination of fuelusing engine-electrical drive is old. Professor Porsche invented an Artillerytractor before ww II at Austro-Daimler, the Landwehr-Train. It may not have a high transportation speed, but was on of the first hybrid vehicles for pulling devices. www.hybrid-vehicle.org/hybrid-vehicle-landwehr.html |

Some ideas are way ahead of their time and get shelved until some body comes along with some new technology or ideas that make the old idea work. Who cares if diesel electric is 100 years old, sound great to me |

It may not have a high transportation speed, but was on of the first hybrid vehicles for pulling devices. The landwehr tractor isnt exactly a hybrid, but a petrol-electric. It has a petrol power source but an electric transmission. In order to classify as hybrid, it should be able to move on both electric power (from batteries) as well as from petrol engine power. However i see that my idea of hooking up the silage trailer with an electric power connection, to feed the trailer drive axles at the same volt/amperage as the tractor wheel motors (diesel-electric ground speed PTO) isnt new either.... ZF is telling they see the future for wheel loaders electric (mostly because of the huge gains you can make by reclaiming the brake energy at forward-reverse cycles, like dumper loading) but they havent mentioned any decade. I'm sure they're testing stuff right now, to stay up front.. |

ok...but remember when the "Landwehr-trainc" was invented. And if you read in "Agmachineries" posting, there is a talk about diesel-electric, not hybrid.
Btw: How far is the way from a fuel-eletric combinated drive to a hybrid?

The counterballast can be replaced by batteries, or the energy can be stored in high capacity supercondensators, that store energy only for a short time, but can release it quickly (which is ideal at shuttle loading) ok...but remember when the "Landwehr-trainc" was invented. And if you read in "Agmachineries" posting, there is a talk about diesel-electric, not hybrid. Yes, this thread is about diesel-electric, but the website is about hybrid vehicles... the Porsche doesnt belong on a hybrid website, hybrids arent as old as diesel-electric drive. Btw: How far is the way from a fuel-eletric combinated drive to a hybrid? Its just one set of batteries away.  In that era, carrying the batteries alone, would use all the cargo capacity of the wehrmacht train... |
