Given all else being equal and taking into account no other variable, will increasing the length/depth of the lugs or cleats on a tracked vehicle such as a snowmobile cause a definable change in the vehicles final drive ratio. For the purpose of this question final drive ratio is to be defined as the distance the vehicle moves with one full rotation of the drive system input and not accounting for any variation in the drivetrain such as CVT etc. 

 

I am open to suggestions but I think the above about covers it.

That's obvious. but dosnt explain your theory.

I have already explained it, linear vs rotational motion. Total diameter only matters when it's rotational motion.

No, it won't be correct, but that's because it's rotational motion, not linear.

 

 

And it's not a 'theory'. This is basic physics.

Calling it a theory is like saying the statement 'water is wet' is a theory

That's all fine, but a track isn't a wheel.

how so

WTF?  

If we're talking overall track diameter, a longer track vs a taller lug would effect final drive, but it doesn't...

True, keep slaining. This is interesting

So why dosnt a taller lug change the diameter of a track? Not looking for anargument , just learning here.

It does change the diameter just like a longer track, but since the track isn't moving rotationally at the point of ground contact, it doesn't matter.

Will you take the bet before I croak from old age????

You're sayin' that lug height does not affect FDR under our hypothetical situation, right?? 

Then take the bet!!!

All other factors being constant, does lug height affect the FINAL DRIVE RATIO on a snowmobile, on a hypothetical, flat hard plane??? 

In other words, will a snowmobile travel further with one rotation of the track with 3" lugs, as compared to that same snowmobile with 1" lugs.

Does a 151" track with 1" lugs have a taller FDR than a 121" track with 1" lugs?

Answer NO.   Track circumference does not change FDR.  

Fuck this is not that hard to comprehend.

Yes

Out of 1056 people on this site, is there no one who can stand up to my power and authority???? 

ANYBODY??? SOMEBODY!!! 

NOBODY!!! 

If someone doesn't give me the name of a fukken lawyer that I can call to send my fukken check, by the end of the week, I will have no choice but to declare,

No it doesn't.   It takes more revolutions of the drive sprocket to complete one revolution of the longer track.   

A snowmobile drive system is a gear system not a wheel system.

You fukken fucktahd!! You're not following the hypothesis!! You fukken tahd!! It's a 121" sled with 1" or 3" lugs, nothing else!!! 

Why did you mention a 151 as compared to a 121!!! TAKE THE FUKKEN BET, OR STFU!!!

I took the bet dumbfuck. The question has been agreed on. Let's pic and engineering firm

Right. So, you need more revolutions to turn a longer track one rotation. Therefore changing the drive to rotation ratio...

This was not the question in the OP.  He didn't ask about one full rotation of the track.  He asked about one full rotation of the input.

@motonoggin is correct.  Lug height is not what's important.  The track is being laid down and the bogies are rolling across it and slides are sliding across it.  Regardless of lug height, if the track driver pitch is exactly the same on a 1" lug or a 3" lug, the suspension will only roll one driver rotation-worth of track LENGTH.  Assuming no lug flex is present.

Put another way, if the circumference of the driver is 20 inches and there's a 4:1 reduction in the chaincase, one rotation of the jackshaft will result in 5 inches worth of track being laid down, regardless of the lug height.

Hey moron what does going from the 1" lug to the 3" lug do?   Increases circumference.    So does a longer track at the same lug height.

Anyone who can watch this video and not clearly see the thickness or length of the conveyor does not make the object traveling on it go faster is obtuse or a fucking retard.

Why are you bailing them out!!!!!!!!!!!!!!!!!!

I knew you weren't my bud, that's why I included you as a member of the " N.H. FUDGEPACKERS SNOWMOBILE CLUB "!!! 

I was not sure about you, but now I see I was right.
