Wow big trailer I want it

 

:welcome:to prius chat

 

It looks there is a huge imbalance among track and trailer.
Wonder if there is a safety regulation in the US.

Simple solution. Sell the Honda, buy a Prius. Remove hatchback, mount 5th wheel there. Put truck inside trailer, hook trailer to Prius. Drive.

 

not gona lie Im from powerstroke.org im not here to stir the pot.
just watchin
not my first post ether you blocked my old account...

 

Just how heavy is that trailer? I'd want a one ton dually - not lifted - for extra stability

Back when I was licensed for it, I used to tow upwards of 30,000 lbs loaded trailer, using a Ford F-600 with air brakes. It was built for it

 

Quite frankly, I don't care if somebody drives a Prius, a lifted pickup, or a minivan. Most drivers on the roads these days are ignorant a-holes

Back when I had to do a lot of driving for my consulting business, the Prius made financial sense. But it was all a write-off too.

There is no way I'd plunk down upwards of $40,000 into a toy with no possibility of depreciation, expense writeoffs, or tax breaks

 

Yes, the F-450 has a heavy duty rear axle with integral housing and removable third member. A much better choice for HD towing

I saw one up north of the arctic circle, at a methane hydrate test site a couple of winters ago. It was used to tow up a research trailer for us engineers

Somebody made the foolish error of not draining the plumbing in that research trailer before it left Calgary. Guess what happened to the plumbing once it was exposed to -50 F?

 

I bet a prius could pull half decent not 10k lb but electric motors have great torque, almost instantly too and with the cvt no bangin gears ether

 

Yes, at LRA rating, an electric motor can provide 100% torque at 0 RPM. That's why diesel rail engines, stevedore shipping container cranes, and a lot of industrial process use (Pumps, conveyors, agitators, etc) use electric motors

AC variable speed - variable frequency - electric motors allow infinite torque/speed adjustment. However, the motor winding has to be specially designed and insulated for this duty.

If you have come across the term "inverter duty" that means an electric motor designed for variable frequency speed control. Otherwise, the rapid changes in frequency can cause arcing in the motor winding

Oshkosh Defense is doing very serious research into per-wheel electric motor hybrid propulsion

Oshkosh HEMTT A3 ProPulse hybrid drive, diesel electric vehicle Keywords

I see this sort of military vehicle as having primarily a logistical advantage: instead of needing separate generators, you can leave the HEMTT in "Ready" much like a Prius. The engine will cycle on and off to maintain constant voltage in the capacitor bank

If you watch the video, they use the example of running the airport lighting at Oshkosh Wittman Regional by plugging into the HEMTT.

The fact the HEMTT can still move the big loads, with less wear and tear on the motor, with no transmission or driveshafts to maintain, while using less fuel: win-win

 

is it posible to burn up the electric motor by over loading it in a light duty hybrid (prius,escape, civic)? or do they have fail safes?

 

No, all routine operation the motors - there are actually two of them M/G 1 and M/G 2 - are protected from thermal overload.

There are thermisters in the winding that the PCM (Actually many different computers on CANBus, but for the sake of easy discussion lets just call it the PCM) that monitor temps

You get plenty of warning before things get too hot

The motors are actually liquid cooled. In this cutaway



you can see the cooling jackets. The inverter/converter is also liquid cooled. It's thought the weak point is the electric coolant pump for this loop. But again, there should be enough advance warning that the average driver would take notice

But, just as there are folks who keep driving with an overheat or low oil pressure warning light, there will probably be Prius drivers who will keep driving with the warning triangle on
