Any body running duallies on their AATV?

[Robio_8x8]

I saw an older Attex that had daullies and I was wondering what problems that would create aside from tire cost. They seam to be very close together I would like a little space to run double plastic tracks or keep the tracks guided threw the center. Would this put too much strain on the vehicle?

high. new here, but was going to ask this same question. also would like to know if there are videos with anyone running them?

I can't speak to specific AATV's but, in general engineering:
Duals will put larger leverage forces on the axles and bearings, since, the furthest contact will be farther out.

( a statement from the reduntant dept. of redundancy)

So, stress' on the bearings and attaching points will be greater.
I'm sure they're made to take a lot of force, considering the jumping, etc, that is done with them.

Creating a dual set up can be challenging, if made strong.
you need to lock the rims together somehow, either with a spacer between, or, locking tabs on the rims themselves, and, an attachmemt mechanism for the outer rim.

If the duals were for running tracks, it'd seem using narrow tires would be the ticket. They'd create the gap you're referring to to run a centering "strip" in the middle. And, the rims could be run tight against eachother, for strength.....
I'm sure someone makes a set up, maybe a person could copy it? I've seen pictures if these rigs with duals.....

Since I want to get tracks for my Hustler, I'm also interested in this, and, will be working towards a solution, if one can't be found already engineered.
(I hate re-inventing the wheel.........)

Good luck

I also cant speak from any experiance. But if I wanted a beefy set up, it seems that if between the tires you put a pillow block bearing. Then run square stock or whatever between the tires to connect all axles in between the tires would help out alot for strength. Im not saying its needed or anything but sure seems like it would help out alot for strength.

Other bearing types could be used but that seems easiest. There are dual wheel setups with basically a hub mounted to each side of a piece of tubing. That strengthing rod thing wont work on that style. For that to work you would have to make new axles longer and then make/buy 6 new hubs with the tubes that are bolted on and put 2 stock style hubs on each longer axle.

I can see how that pillow block set up would make it stronger front/rear, but, it would seem you'd need some sort of brace from the bar to the body in at least two spots, to create a triangle for rigidity.....
othwise, it could pivot by virtue of the bearings.
Or, am I looking at it wrong?
It'd still put the same forces against the bearings as far as load and 'suspension' action, unless, that load was transferred up from the bar to a framwork.......
Which, might be difficult with tracks.

What you designed, does, though seem a good way to reinforce and moderate for shocks from running into stuff.

Just some random shade tree enineering thoughts......

It'd be good to work it out, and, come up with an idea, if there's not a good one out there to copy.

I had an amphicat with duellies on it last year, yes 12 balloon tires , 12 hubs, 6 axles. it was very neat! i sold the cat without the axles and hubs. they were 3/4" axles too.. i liked them.. still do, going to re do a cat soon... he he

So you must of had no breakage. How did you drive it? I mean did you baby it or did you just drove as you might normally drive.

duellies

hi, It was some weird driving, since i am used to regular 6x6's.of course i semi babied it.this was apparently an origional machine as far as i know, there were only 5 made for demonstration/show purposes.. i didn't want to break it, Where would i get repacement axle (s) immediately? Yes they can be made too.. it really give a fella some ideas... humm.....

How was the ampicat with dellies ?

Did the Axles hold up ok?
I was thinking of trying this next year and was only going to be doing it for the snow with Extra super wide tracks . This way I would only need to build guides in the center of two tires.

Imagin an 8x8 with duellies or should I say 16x16

strange? won't your argo work with just a regular set of tracks in the snow? amphicats do...
Maybe you have different snow in Canada? he he

[Robio_8x8]

I still need to get or make tracks

My snowmobile got stuck a few days ago. The snow was extra fluffy and deep that day.

It has actually been really strange year I do not ever remember getting so much snow for so long but we do get all kinds of different types of snow were I am. From fluffy powder to ice then all pointes in between and sometimes different layers of each type . Right now I am hiding from it all Toronto. only 2 hours south but it makes a big difference .
Last year I only go one month of snow
