    Early Watsonian Monza tied to anXV535 Virago, with an upright shock,and 31/8" pcd hub, The wheel recently broke up so I made an aluminium hub with 4" [CD and fitted a mini cooper 3.5" steel wheel, and got the offset sightly wrong so had to thin out things on the inside toprevent tyre rubbibg. Heavy steering was sorted by angling the steering stem 5 1/2deg forward in the yokes. Sidecar shock is a Gazi race car shock

    Good old Torsion bar suspension for this mid 60's Globe GS200 sidecar. No complaints from the wife who loves to ride in it. X7bcHOnAS3+1cBVFi+mi+g.jpg

    So if I get this correctly there's a torsion bar arrangement in the swing arm mounting plus a rubber buffer (grey cylindrical thingy) and two rubber stops at max and min travel? Plus the back of the tub is suspended by rubbers? Is there any adjustments or is it just set?

    Cheers,

    Rant.

    It’s bracketed to the hoop, in double shear. Already in paint, and in service. View attachment 1781702

    That’s correct. No adjustments that I see. I guess that was the technology back in the early 60’s.

    Not sure if this is where you post brain farts but I went and had one but searched youtube and like most of my other ones, somebody had a better one. This will probably trigger one of your own:

    In 2010 with the Oshkosh LCTV we raced in Baja we used an active suspension system. Each shock had position sensors and accelerometers so a computer could know how fast the shock piston was traveling through the stroke and an adjustable orifice would change the damping. Additionally the amount of steering input was used so the damping of the shock could be used to reduce the body roll and eliminate the need for anti-sway bars. Pretty good as each wheel carried a 2,000 lb load and had 36" of travel!

    If you put together an outfit, I'm putting a big red triangle on the back of mine.

    As mentioned in the video Citroen already did this, here's a video of some Citroen 3 wheelers using this suspension in action:

    Chair's suspension on my Stepler/LBS Zijspantechniek English-designed/Dutch-built sidecar. I purchased the prototype and had it shipped to me here in Seattle, and we're still in the throes of re-finish and re-build. Did have the opportunity to test-drive the first production rig in Holland recently, impressive handling, though I didn't get a chance to run it on the freeway or off-road:

    Looks like they adapted a BMW final drive into a billet block of aluminum, without the pinion. Talk about doing it in the most expensive manner possible.
