Frictional damping assembly for suspension strut
First Claim
Patent Images
1. An improved frictional damping assembly suitable for use with a suspension strut, comprising:
- two spaced apart wedge rings and a plurality of damper wedges engaged between said wedge rings such that axial compression between said wedge rings will cause said damper wedges to move inwardly in generally radial directions with respect to a bore which extends through said wedge rings;
each of said damper wedges having an anterior surface which fronts upon said bore, and which is bounded by two parallel side surfaces and two opposed wedge ring contact surfaces;
at least one of said wedge ring contact protruding outwardly into and conforming to a radial groove formed by one of said wedge rings so that said anterior surface has two portions, a first portion bounded by said side surfaces and a second portion bounded by said one wedge ring contact surface, whereby the aggregate area of said anterior surfaces is equal to the the areas of said first portions together with the areas of said second portions.

Abstract
The assembly includes three damper shoes that are guided by and wedged transversely between two wedge rings, one having three curved flats and the other having three planar flats that respectively contact conforming contact surfaces of the damper shoes. The assembly is particularly useful in a frictionally damped suspension strut.
