Ok since I have no money and no time and no prayer of ever getting my idea patened. Or to even consider making a buck off of it. I want to throw it out to the dawgs the BIG DAWGS that it is.

I have been designing a reduction clutch disk and I have it almost all worked out, but have no money or time (did I say that I have no money or time well enough)


So if anyone wants to build it. I will fill them in. I would like one though.

basicly its a planetary reduction gear set built into the clutch disk. this would facilitate no drive line mods to gain a 2:1 reduction in all forward and reverse gears.. Not for the daily driver...

I belive this could be designed to work with all heavy duty truck type trannys.


What ya think?

Flame on.................

Ok either the first 25 folks just ripped my idea and split or everyone thinks I am a whako.....I just can't figure out why they didn't flame me...


COME AWN say something .... I bite... but.... well... I have been working on that..

Seems like it could work, ror a competive rig I could be a lighter was to get needed reduction.

It will work BUT it has the draw back of not being able to take out of gear. So for sure its for a full AWN rig or for a rig with a higher geared truck tranny like a scout T-18 narrow.

2 times torque going through the transmission is not going to be a good thing I think. Do you know of any transmission that was designed to handle 2 times the engine it was intended to go behind?

You could blow up an NV4500 with a 4.3V6 with the kind of torque that would make.

With my engine that would mean that I need to find a transmission that can handle 1100 ft#'s of torque. I don't know of any transmissions that would handle that.

I don't like subjecting everything behind the engine to extra gearing. I am a beliver in low axle gears because they sheild everything before them. They also lessen drive shaft torque , which lessens things like suspension torque jacking. Having super low gearing befre the axles whether in the transmission,trannsfer case, or clutch for that matter can make for some wicked torque jacking espescially in off camber/steep climbing situations.

I brought this up in thread last week. and the major consensus was that the torque would not be beyond design use.

However I agree there could be serious carnage in right situation. though it would give the FULL AWN comp dawg the use uf allot more gear options and since you could use higher gears in the tranny to achive the desired reduction range you would be using numericly higher gears more often.

An NV4500 is only designed to take 450 ft#'s according to New Venture right? I am sure there is a bit of a safety cusion there, but if you are running above that number all of the time it is going to fail quickly.

All, I am saying, is that it would take a HUGE transmission behind a small engine to live up to the abuse. Could you see a 22re with a Clark 2.5 ton 4 speed behind it.:eek: A Toyota transmission definitly I.M.O. is not going to take the 22re x 2.
Same with Jeep 4 cylinder and NV3550 , I dont think it would live.

This wouldn't be an option for rigs with a stong V8. No cheap/ readily available transmission could handle that.

I acctualy have only considered the T-18/19 the SM420/465 and the NP435.. The NV4500 has allumiun case so I had discounted its use as a major player. but the reductions does not have to be 2:1 it coule be 1. 1/4:1 ...1 1/2:1 I felt 2:1 would be max for any transmision.


I am equating this to same changin engines and installing diesel high torque motor over small I/6 or V8 gas engine.

Or doubling you Horsepower

the way that i am envisioning your idea is a planetary gearset in the hub of the clutch, if this is right how would you lubricate the gearset without the centrifugal force getting the lube on the clutch? also this would possible make the diameter of the clutch larger, which would be a good thing, because it would grab harder.

Why not... see that way when your transmission does its impression of a handgrenade ,from being massively overtorqued, you only get blasted with pieces of alluminum unstead of cast Iron. See its way safer that way :eek:

Clutch would not be bigger, as frankie has pointed out you can't do that.

Planetary yes, sealed for lube built into the hub, Size of the gear set may acctual kill the whole thing since if you gain to much you end up with the need for a newly designed pressure plate.

Heat may be a problem but only prototyping can say for sure.

you dont need a bigger clutch disk since you would be spliting the reverse torque (pressure) so you pressure plate would have greater advantage on the disk under load.

consequintly the tranny now has greater leverage on the disk under compression.

The thing would work, the real issues are tranny life and useablity... the average wheeler doesnt want to double his forward gears (all of them) however with some calc work we could use something like this to begin regearing our rigs for numericly higher gear reductions and there by using larger stronger gears in lighter weight rigs.

ItsaCJ - this is an interesting thought, but there are just too many other easier ways to get gearing...

I agree

But with this idea you have no increase in drive line length over a stock aplication and it presents lots of options. your 6.37:1 T-18 is now a 12.74:1 first gear tranny and allows you to run alomost any transfer case an get the equivilet of 4:1 with out the major cost. It would allow those who chose to run NP 205's in short wheel base rigs and still have an effective 4:1 in the shortest possible pacakge.

I know this is already possible but hey it was an idea.....


anyway I belive it could be a great tool for the right application I just can't get one built with my limited resources. So if someone eles wants to I will fill them in on what I have come up with.

Damn Frankie you sound like your at the bench the morning after

... Ahh your honer I was wrong to drink all that beer and smash that short little fellers head in... I shoulda just let him talk about your momma....

its a good idea but i dont see how it could be done, im guessing the clutch dish itself is attached to the sun gear and the input shaft to the tranny is attached to the center pinion but what holds the planets from rotating?


BTW about that increased torque thing, Advanced Adapters has a reduction box that bolts to the front of any manual tranny to give you either overdrive or underdrive.

In fact, the NVG 4500 does NOT have an aluminum case! The tail housing is aluminum and so is the top cover, but the case is good old cast iron. 200# bastard to install. Have one sitting on my shop floor as I type this. :D

looks like its been done, oh well
