PTO e-drive

[manic]

One thing I dont like about owning an old diesel is a start up in the garage. There have been times when I have had to go back in there, and gagged on the fumes!

I tried to push about the garage on the starter motor once, and blew the maxi fuse!

Im really curious to know if a useful electric motor could fit behind the PTO on a D1. I would add a small litium battery pack onboard for a 15-20km range. Enough to get me off the driveway and cover the pops to the shops where max speed is a low 60kph.

Beyond 20km, I fire up the diesel and keep on trucking.

There are a number of hurdles to clear, but the biggie is the motor and lt230 configuration. What size/type motor might be suitable, if any.

And if a motor can be made to fit would it have enough torque to push the disco through a 1.4 box. Im not familiar with the inner workings of a PTO, how much torque can you put through, can it be used to direct drive through high or low range, or must it set its own ratio?

Thoughts?

I can't see how it'd work(to drive the vehicle, that is).

For the PTO to provide drive, it has to be in a gear.
Putting it in a gear, and then clutch out, then couples the engine.
The electric motor then has to fight the (now coupled) motor and provide drive.

If you could figure out a way to decouple the motor from the gearbox whilst still maintaining gear ... :confused:
ie. you need another release system between engine and clutch.

Wouldnt depressing the clutch the whole time disconnect the engine from gearbox...assuming it’s a manual.

Than you could drive through the PTO although you would would have to be happy with the gear you select.

There is no PTO internals in the t-case. The PTO is bolted onto the t-case connecting the the main shaft.

I get the idea of a small drive to get out of the garage but not sure it’s the best solution for trips to the shop.

Is the diesel fumes that bad?

And you would have to have the engine running the whole time for brakes and power steering.

Yeah, of course, but I was referring to not having to drive in such a manner(ie. drive full time with left foot on clutch).
If you could rig up a full time manual override for the clutch(ie. leave that leg free for whatever else).

Then the question would be, what impact on the clutch system that kind of drive system would have.

I thought the PTO is driven off the engine but with the transfer case in neutral it's disconnected from the wheels. So gearbox in neutral and TC engaged would be fine. Brakes are easy, you only need an electric pump. Steering is likely a bit more difficult.

Or just wait for the latest Range Rover offering, I know you want one...

I was thinking gearbox in neutral, electric motor providing drive through the transfercase to propshafts. Is that not possible?

Looks like land rover managed to use the PTO.

Concentrating on the PTO and e-motor for now, and trying to figure out if it could be done given the challenge.

Anyone with ideas, links to technical articles that might help, calculations on motor size required to push the gearset, useful info to help rule in/out the possibility of mounting an emoter to the lt230, etc -> please post.

To figure out:

- Can an emotor drive the props via pto through high/low gearsets when gearbox is in neutral

- Minimum motor size required to push direct to wheels through low range, potential top speed.

- Minimum motor size to push through high range.

- Any negative effects from ICE turning the emotor in diesel mode.

-Any negative effects from emotor on driveline when in electric mode.

if you add a one way clutch PTO to the pto shaft it would allow the electric motor to overide the diesel when it was able to .

Of course it would work . The Advantages are many.

You could run the Engine & motor together , there is no fighting of the coupled drive .
Tesla have two completely seperate drives for front & rear wheels & so does the Bollinger B1

If you leave the Electric motor coupled into the system you can make it free wheel, regen , or drive with a simple pot adjustment . When you back off the ICE power the Electric motor would provide regen braking . You could put TC in Neutral & run the ICE with vehicle stationary to spin the motor & charge batteries . Then drive on Electric only .


Im seriously considering doing this on my Iveco .

not needed . if the ICE is providing more power than the Electric motor the motor goes into freewheel , no drama , same as if you started going downhill .

vice versa
