Yeah, IIRC there is a section or two in Carroll Smith's book(s) that talk about adjustable anti-roll bars and the mechanisms. This kind of thing is far from new.
If it is what I suspect that it is, I have a model of it around here somewhere. I've been proposing it as an option to disconnects since about 1998. The idea is far from new, I first saw it used on an Indy car in 1996. I'll guess that the chassis that I saw it on was at least 3 years old at the time, which means that F1 probably had them for 10 years prior to my seeing it.
Full Soft setting:
![]()
Full Stiff setting:
![]()
Forget about it being tunable, which was the F1/Indy car goal. At any setting other than full stiff or full soft the tip of the blade will deflect laterally in the direction of least resistance. The result of this being that the swaybar's effective stiffness is nearly unchanged until very near the full stiff setting. Which really doesn't matter for OR use. Generally we only care about the two extremes anyway.
In an effort to stop the lateral deflection the Indy chassis that I first saw it on had been fitted with a cage and the tip of the blade had a sealed bearing fitted to it. The cage contained the bearing and limited the lateral deflection to a minute amount, but it also removed some of the suspension's dynamic suppleness in the process.
When & where can the item be veiwed?
