IMPROVED FRICTIONALLY DAMPED SUSPENSION STRUT Abstract of the Disclosure The strut includes a telescoping load bearing assembly that extends through a composite spring and a frictional damping assembly. The damping assembly includes one, two, three or more movable damper wedges that are urged by two wedge rings against a sleeve bearing that normally provides for low friction extension and contraction of the load bearing assembly. In response to application of an axial load on the load bearing assembly, however, the damper wedges press or squeeze the sleeve bearing into gripping engagement with the load bearing assembly, which causes the sleeve bearing to apply frictional damping force to the load bearing assembly. Elastomer layers interposed between the interactive faces of the damper wedges and the wedge rings are placed in visco-elastic shear in response to movement of the damper wedges and, hence, provide essentially frictionless movement of the damper wedges under such conditions. This enhances the sensitivity of the strut to certain road conditions. In a second presently preferred embodiment, the damper wedges are replaced by a single split wedge ring.
