With my set-up, each of the forces acting upon the axle is controlled by linkages that are independent of each other. ie. The radius arms only control fore/aft movement. The torque arm only controls axle housing rotation. And my Ritson linkage only controls lateral movement. Which ultimately I believe is a stronger, more accurate and reliable arrangement.
Each of the linkages in a dual triangulated 4-link is doing 3 functions. Fore/aft axle location, lateral control and axle torque control. So it's possible to be in situations where all three forces are combined and act upon the linkages. Imagine what's going on with a loaded truck descending a side sloping rutted track and hit the brakes too............
You're right in that your suggested set-up does do that too.
However I felt that the strength of that would not be adequate. Remember this is a 4.5t GVM truck that will get used for everything and all terrains. It's not a light weight Jeep offroad toy. Not knocking them, they're capable and fun.
looks like a great setup but not practical for autombile use. Seems to be a lot of parts that could break or twist out of alignment and adjustment would be very tedious. Also you have to consider the direction of the forces acted upon it for example the lateral or horizontal forces against the assembly. These forces would cause it to react much like a panhard bar but at least it does move up and down vertically.
I feel the watts link does this nearly as well but may not have the travel
The length of wood forming the "axle" is at that height to support the linkages at the height they will be mounted on the axle. I would have liked to have them mounted much closer to the axle housing tubes, but with a steering assist ram mounted in front of the diff, I couldn't package it there.
but isn't that complicated?

why would you go through all that trouble to accomplish what a dual triangulated 4 link with heim joints already does so well?

watt links are less complicated.

Thanks.
I think you're right re: not being practical in most cars and 4wd's. I developed it to achieve proper accurate control WITH long suspension travel.

Looks very promising, if a little complicated!

Yes it's not the simplest means, but achieves the objectives required.

Thanks for the information. Are you using a coil spring suspension or leaf springs?

Neither.
I'm using airbags.

Are the axles portal type axles? Like the type that are on a Unimog?

Unfortunately not.
The length of wood forming the "axle" is at that height to support the linkages at the height they will be mounted on the axle. I would have liked to have them mounted much closer to the axle housing tubes, but with a steering assist ram mounted in front of the diff, I couldn't package it there.

Did ya ever fabricate,install, and test it ?
