I've been kicking around a few ideas for this. Which do you think is better for a light weight rig used primarily in snow?

1. a full length track on each side. skid stear.

2. 4 individual tracks, front steer via knuckles. rear fixed

3. front and rear steer via knuckles.

4. front and rear steer via rotating the entire axle ie tucker snow cat.


I'm leaning towards building the 4 individual style, with a rig built specifically for them with 4 way steer. Also that would allow me to put them on any 8 lug rig I own.

I am thinking of full tracks, I am just not sure about the suspension.
Each bogey wheel could have it's own suspension, or each track suspended as a unit, or a combo.

Your number 2 and 3 seem like they would be easiest on the ground vs a skid steer.

What about ground clearence? Most tracked vehicles don't have that much. I wonder if it is worth the effort to design in a little more?

For a single track per side I was thinking a dual "A" arm system front and rear. Like an IFS Chevy. Use a long piece of rectangle stock or square stock mounted on the "spindle" running front to back. Your front and rear wheels would attatch to the a arms and the bogies could have independant susp. off of the long tube. You could use coil overs or just coils for the main susp. And trailer torsion/elastic axles for the bogies. I think that would give added clearance in the middle of the rig. Use an IFS chevy front diff and cv's for your drive.

you could make the tracks in an A formation having the drive s*****et at the top with an standard axel and mabey a selectable locker. then come up with some sorta shock design or airride setup to keep it leven and flexy.


or make the tracks look like below with the axel at the front or rear. on the top edge. with a selectable locker. both these would have to be a skid steer.

While that thing does look fun, that's not quite the type of use/recreation I want out of my rig. The suspension on that is just the std. military armored personel carrier variety, modified slightly.

If multiple IRS suspension setups were used and full size wheels I think it would be more durable then bogies. This seems to be more like most modern tanks.

Also, if they were all powered, it could be a skid steer 6x or 8x.
When you throw a track, it can still go.

I want mine to float.

Actually, a half track would be real easy. One powered axle, and one tag axle, wrap a track around it and done.

I daydream alot.

selectable lockers while nice, I think would be rarely used. The traction gained by that much surface area would negate them in most cases. Also there would be absolutley no steering while locked.

The problem with a tri-angle type track is it's tendency to want to "curl under" under load or when placed against an immovable object. You need some sort of attack angle, and an anti-torque device to make them work really well. I have an idea in mind for mine when I get that far.

you would use the selectable ones so that when you needed to turn flip a switch=zero turning radius

with the axel locked you wouldnt be able to turn with a skid steer design but flip a swith to unlock the axel and walla. got a off road bobcat

I'm still not following you. Without a hydro static differential you can't get each track to turn opposite directions, locker or no locker

no I'm working on the premise of the inner track just not moving.

could always use a little motor to run a hydro pump then have two individually controlled hydraulic motors. then you could have alota clearance with no axel.
