torsion axles

Has anyone ever designed a torsion bar type axle for Airstreams? A torsion bar, solid or hollow( to save weight) mounted solidly in the center of the axle tube and on the other end to the arm that holds the tire. One for each side, of course. It would get rid of that rubber stuff, and be nearly indestuctable. I can hear Andy fireing up his keyboard already! LJH

There have been independent torsion axles used on light utility trailers, but nothing that would carry the weight of a large travel trailer.

Roger, Tanks use torsion bar suspention. They weigh mucho tons, so strength is not a problem. LJH

Yeah... the only ones I know of for trailers tho are really light weight. Perhaps you've just come with an idea for a cottage industry?

The current axle set up is a torsion (bar) axle using rubber rods contained in a metal tube. An all metal torsion axle (like Chrysler products used in the front end of some products of the 60's and 70's) has not been used in Airstream production.

Torsion Suspension

Don't forget the original VW Beetle. Front and rear suspension both used torsion bars and were adjustable for sag as were the front suspension of selected Chrystler products (wow, what a concept).

I'am thinking that a torsion bar set-up would be wonderfull. It could be adjustable for ride height, within a certain range, and would never wear out, or take a "set", like the rubber ones do.
Would not have to weigh that much more, but might be more costly,,,,,but if they never needed replacement,,,,,well,,,,,ok.
