  • Linkage rod with shock absorbing
    Patent number: 5230407
    Abstract: A linkage rod for absorbing shocks and vibrations has a housing with a central bore. A spacer tube and a spacer load plate are inserted into the central bore. Several resilient members preferably formed of crimped metal wire strands are located in the central bore between the spacer load plate and a piston load plate. A mounting member has a shoulder formed between body and neck portions. A snubber cap having a central opening with an inwardly-directed wall is positioned around the mounting member. A snubber nut is attached to the mounting member to trap the inwardly-directed wall between the snubber nut and the shoulder. The snubber cap is fastened to the housing and the mounting member may move axially relative to the housing. The resilient members resist axial movement of the mounting member.
