    • A method of manufacturing a fluid-filled, vibration damping bushing assembly, comprising the steps of: Forming, in a first molding step, a bushing member comprising a elastomeric core having an axial bore therethrough, the elastomeric core having a circumferential exterior surface including at least one fluid chamber, the circumferential exterior surface being partially surrounded by a metal cylinder vulcanized to the elastomeric core in the first molding step; reducing the outer diameter of the bushing member following the first molding step; in a subsequent, second molding step, mold-bonding one or more polymer sealing elements to an exterior circumferential surface of the metal cylinder; in a next step, disposing at least one fluid-channel member over a portion of the exterior circumferential surface of the metal cylinder; and providing a fluid in the at least one fluid chamber, and fluidly-sealing the bushing member, the one or more polymer sealing elements, and the at least one fluid-channel member, within a housing. A fluid-filled, vibration damping bushing assembly manufactured according to said method.
    • 一种制造流体填充的减振衬套组件的方法,包括以下步骤:在第一模制步骤中,形成衬套构件,所述衬套构件包括具有穿过其中的轴向孔的弹性体芯,所述弹性体芯具有周向外表面, 至少一个流体室,所述圆周外表面在第一模制步骤中被硫化至所述弹性体芯的金属圆筒部分包围; 在第一模制步骤之后减小衬套构件的外径; 在随后的第二模制步骤中,将一个或多个聚合物密封元件模制到金属圆筒的外周表面上; 在下一步骤中,在所述金属圆筒的外周表面的一部分上设置至少一个流体通道构件; 以及在所述至少一个流体室中提供流体,并且在壳体内流体地密封所述衬套构件,所述一个或多个聚合物密封元件和所述至少一个流体通道构件。 根据所述方法制造的流体填充的减振衬套组件。
