I have owned numerous tractors and have always filled the
wheels with water for better traction on the beach operating at a max of 30mph
they last for years I use oil filled axels with double seals and never have
bearing problems water also weighs nothing in water.Check these sea legs out www.Porta-Bote.com.
All the best

Hi Glen, Now you've done
it. You've got a very sharp can opener. Another can of worms I see here. I was
thinking along those lines for the larger 35 foot floating pontoon trailer I
was thinking about using to hold up my tow vehicle on the water, and tow the
sub with, so I don't have to leave any thing behind, and perhaps leave the
water from another location. Once the tow vehicle is lifted up between the
pontoons/amas, I would need to drive the whole works into the water, and later
also out of the water. This arrangement would also include retractable and
steerable front tires.
Since which ever end of the
floating trailer that is put into the water first, will start to float soon
after entering the water, the remaining end will need to have the powered
wheels near that end of the trailer, to come in and out, as well as keep the
trailer from scraping the ground.
Some time back I was working thru
some ideas for a submarine SUV and needed a way to deal with the compressible
and overly buoyant air in your standard pneumatic tires. Then I came
across a new type of free flooding wheel, called the Tweel, by Michelin Tire
Company. But as far as I know they are not available as of
yet.

Then I took a look at the company
called Setco, that a gentleman by the name of Buck Hill owns in Idabel,
Kansas. As some of you might know, Buck Hill helped Karl Stanley build his
last sub. Setco makes really tough mostly solid rubber tires for heavy
equipment. Some of the tires they produce have some great traction. These I
consider to be a possible option for fully submersible to depth submarine
wheels, that could be installed on a sub in many different configurations.
Then you can just drive your sub off it's trailer, and into the water. Among
other things.

Even better for traction would be
to use a rubber track system like you see on small track hoes, and some Bobcat
earth mover units.

I had not thought about water
filled wheels. Why not rum or the like? arrg ;} I'll have to
ponder that one for a bit.
As far as oil filled hubs go, the
first ones I've seen were on the fifth wheel trailer, that is being used to
haul the S101. Here's some pictures of that trailer.

Hi Brent
Why not electrically or
hydraulically driven with optional
freewheeling retractable water filled wheels and oil filled hubs
fitted directly to sub with some draw bar arrangement....just a
thought

Hey Frank and Brian, My
relative that has build a good number of nice trailers, likes to use Torflex
rubber torsion suspension axles from Dexter Axles. They have a nice clean
look and they are lighter then your standard leaf spring axles with the same
load capacity. This also mean you can get away from rusty leaf springs if
you wish. There attachment means is simpler as well.

Dexter
also carries a line of axleless wheel assemblies for those that want to be
able to lower a sub between the wheels with out the axles getting in the
way, and to be able to transport the sub with it having a lower CG when on
the trailer. These axleless wheels are much like the larger ones you see on
the semi truck trailers that pick up bins of freshly picked fruit, and then
transport them to the packing houses.
I've toyed with a few ideas for
a floating sub trailer that you could let most of the air out of the
pontoons to launch the sub, like some ski boats are launched from a float
system that is attached to a dock with a air compressor to refill the float
system. But I think I would rather have the floating sub trailer with it's
small walk around deck to stay on the surface so the launch crew don't have
to get wet if the sub is being launched away from a dock or other support
boat.
Here are some pictures of one of Aerocet's models of amphibious
floats. The retractable wheels with disc brakes are very nice. I have
been thinking about a larger floating sub trailer with two sets of wheels
like this to be able to handle the weight of my tow vehicle, when it's is
being floated by the trailer after the sub has been launched. But that's
another story all together. If I was making my own floats then I was
thinking of making attachment arms for electric thrusters, that are attached
to the retractable wheels assemblies, so that when the wheels where
retracted, that the thrusters would come down in there place to save on
actuators.
