Abstract
A shock absorber strut that includes inner and outer tubes which slide one over the other in a telescopic relationship. In the space confined between closed ends of the tubes, a stack arrangement of compressible elastomeric material pad assemblies is provided to function as shock absorber medium. Each assembly has a pad of compressible material having a central opening, a metal plate having a corresponding central opening and abutting one end of the pad, and a flanged bearing through said openings and abutting the plate to the pad. The pad has ends provided with a series of different sized bores cooperating to define flow spaces for compressed elastomer material to avoid contact with the guide rod. A guide rod extends substantially through the strut through the bearings. The entire arrangement of the bearing provides a glide path for the guide rod. Each plate has a plurality of holes, sub-peripherally located, the holes having torn and jagged protrusions engageable with the pad end.
