My design
My suspension system. I’ve used a hydraulic front fork off a mountain bike. My next itteration on this basic design will use a elastisomer (Rock Shock) front fork but keep the system of linkages and seat post/saddle attachment. This system (gotten to quite by accident) allows the linkages to be relatively short there by keeping the torque forces in them low, The actual holding up forces, the ones that keeps the seat up is almost through the axle. Unfortuantly the tolerances on the linkages have to be pretty close, within three thousanths or better. This one works fairly well on broken pavement and rocks you don’t feel anything but a nice smooth ride. I can twist turn and I don’t feel any slopage or hesitation from the linkage. So far the bushings and fits have stayed solid. So like I say I’m working on the next itteration.
