High filtering power joint with integral bearing-controlled axial clearance, and applications

Abstract From the Canadian patent

Elastic bushed joint with high filtering power and play controlled by integral stops comprising an elastic bushing (1) between coaxial rigid components (2) and (3) characterized in that a layer of significant thickness (7) covers each axial-effect shoulder (4) of the inner sleeve (2) to stop axially on the necked-down flange of the outer sleeve (3); in that the stop function in each axial direction, provides filtering stiffness twice to five times less than the radial stiffness; and in that beyond the filtering zone, the axial stiffness becomes progressively greater than the value for the said lateral stiffness. Application to vehicle suspension arms and to anti-vibration isolation for …
