and people think TTB is weird...

[bobbywalter]

I'm not saying that it looks ineffective. I'm looking at it like a CVT. It does what it was designed for well, but for the parts and engineering involved, not nearly the most efficient method of accomplishing the end goal.

its not the most efficient by todays standards...but late 60, and 70's, well it worked perfectly.(and no it did not work perfectly, there were many quirks) but it worked well.

a more efficient method is the one we still use today, go drive a fullsize factory gm awd van. low and grippy. well done imo.

then theres the sas that has been done all along. look at a conventional 4wd van and then one of those, those are definitely better for something that required a little more traction in shitty conditions for roads, be they paved with water ice or snow issues, or gravel, dirt or two track and not off road 4x4 baja adventure.

i actually did design something similar,but with a different intention in mind about 8 years ago.it was to go to all four wheels and used a trailing arm front/leading arm rear suspension.it's intention was for extreme travel without having to tip a diff for articulation.

it never got built.

i've never seen the ones pictured before,but it looks like an interesting setup.

Seems to me, that dana was not impressed with their idea for hte TTB seeing as it is so asymmetrical with long short arms etc. Looks like an attempt for symmetrical design. better balance and such.

Dang, I would hate to re-gear those. Buying 2 sets of rings & pinions is bad enough, but 3 sets.

I like the IFS 4x4 better. The front diff stays put and CV shafts do all the flexing. Rather than with the TTB and having all that geometery flex work in the drive splines.

I guess it would be alright...

Hey Tom, build a hybrid TTB D50/60 setup like this.

That would be sweet.

Like a Halo Warthog. A diff for each wheel

 

[feellnfroggy]

if it could be built as tough as teh warthog, I would drive one lol. Especially offroad!

Essentially like a Portal axle?

No. If you look closely at the pic I posted, there is no Axle going from the left side to the right side.

Each wheel is fully independent from the rest.

that's exactly the idea.....too bad it never got made.i was collecting parts,but it was at the same time my business was going under.i had to scrap a few ideas at that time.

if i live long enough maybe i'll get to try it out

The time I spent working in maintenance at a golf Course where most of the equipment was 4 Wheel drive,the engine ran a pump with a hydraulic motor at each wheel.
I often thought how the same type setup would work on a bigger scale for off road.

I believe the Halo Warthog was 4 wheel independent electric drive. I think the engine was just a generator. Kinda like the "Electric Wrangler".

thats a pretty neat find. never seen that before. glad you posted it!

This is also quite common in ag. a lot of sprayers are set up this way so they can drive over the crop with the tires between the rows and never disturb the crop. they are also capable of about 35mph which makes them a little bit less of a nuisanceon the road, compared to combines and tractors.
