    Split (decoupled) anti-roll bar?

    This is getting somewhat off-topic at this point, and it might be wise to start another topic on the Kinetic RFS, nevertheless…. I am reasonably certain that the device in the center is a reservoir and equalizer. There is really no point in putting an accumulator there—it just softens the action...

    Cam drive noise reduction

    I don’t know what a nodal gear drive is, but the Citroen 2CV had a very simple zero-backlash cam gear drive. One gear was a normal helical gear, while the other was composed of two half-width helical gears on a splined shaft. A spring between the two (a belleville washer would be better) pressed...

    Super Seven chassis design

    If you want to try something really radical, I have some articles on eliminating the torsional stress in the first place. The first one transfers torsional loads directly to the opposite end of the car through the suspension, so that the chassis never has to cope with it. The second eliminates...

    Anyone care for a comment on: Praxis system

    Air springs don’t have stiction, but raising the operating pressure of hydraulic cylinder does. Increasing the side loading of a strut does too, and adding an air spring to a strut system may do that. I do not have any information on the Mercedes system, but if it is not a hydropneumatic system...

    "Link-X" suspension

    The swing axle is simpler, probably safer and not under patent. Simply move the points of articulation outwards until the roll center is above the CG and you get the same effect. Porsche did the same thing when he stole Ledwinka ideas (Ledwinka’s designs placed the point of articulation at the...

    Split (decoupled) anti-roll bar?

    Freeplay is freeplay and patprimmer’s method would work as well and is certainly cheaper. You could also add freeplay at the anti-roll bar’s mounting to the chassis by using oversized mounts. The problem with all of these is that weight transfer to the outside wheel is reduced until you consume...
