Verfahren zur Herstellung einer zylindrischen Muffe mit einer hydraulischen Dämpfungsvorrichtung

摘要

A method for producing a cylindrical bushing with hydraulic damping includes the steps of preparing an internal ring having an elliptical cross-section including a major axis and a minor axis, disposing within the internal ring a vibration-damping rubber block through which an inner cylinder coaxially penetrates and which has wall portions for defining a liquid chamber, so that the wall portions extend along the minor axis of the internal ring; deforming the internal ring so as to have a circular cross-section; and press-fitting the deformed internal ring into an outer cylinder.
