Tri shock rear suspension
Third spring systems offer a steeply rising rate in ride, without an attendant rising rate in roll.
A monoshock suspension generally has a single rocker, with a single coilover, actuated by pushrods from both right and left wheels. The coilover acts only in ride, much like a third spring. Roll is usually accommodated by having a laterally sliding shuttle in the rocker. The pushrods anchor to the shuttle bar.
A Norde single-axle system, with rubber bushed trailing links and a Panhard rod for axle location, again with a rubber bump stop.
Two inclined rubber blocks 23 bonded to inclined plates 24 secured across the plates 19, and bonded to inclined plates 25 secured to the underside of the load bearing platform by struts 26. - It will however be understood that the plates 24 could be mounted on a block pivotally secured to the beam if desired.
