The elastic articulation or coupling or the like is of the type wherein a metallic inner part such as a ball or a cylindrical sleeve has an elastomeric body firmly adhered thereto, and in turn enclosed by the generally cylindrical interior of a metallic outer part such as a sleeve or an eye, the outer part being joined with the elastomeric body by axial clamping of a pair of annular metallic parts carried at the end faces of the elastomeric body, such that there is solely frictional engagement between the elastomeric body and the outer part. In known devices, various arrangements are provided on the outer peripheral surface of the elastomeric body to enhance the frictional adherence between the elastomeric body and the metallic outer part. An improved such arrangement is provided wherein a fabric of solid material, preferably metal wire, is embedded in the peripheral surface of the elastomeric body, with the fabric wire mesh running generally diagonally to the longitudinal axis of the coupling, such that the fabric together with the elastomeric body are axially compressed and clamped. The fabric with its meshes running essentially diagonally to the direction of prestressing is yieldable in diameter upon axial compression and clamping, such that the fabric moves advantageously evenly into the metallic outer part. This provides good frictional adherence. |
