Abstract

An elastic joint with high filtering capacity and axial gap controlled by incorporated stops includes an elastic ring disposed between internal and external coaxial rigid elements, with an additional elastomer layer disposed at each end of the joint between an axial shoulder of the internal armature casing and a turned in edge of the external ring. Thus, a stop function in an axial direction, which stop function is due to the interaction of the shoulder, the turned in edge, and the elastomer disposed therebetween, produces a filtering rigidity from two to five times lower than the radial rigidity in an equilibrium position, which axial rigidity becomes progressively higher than the radial rigidity beyond the filtering zone when a significant axial force is applied to the joint. Such a joint can be used for motor vehicle suspension arms and in antivibration insulation of mobile or stationary equipment.
