Abstract:
A liquid encapsulated bushing, comprising:a support shaft extending along an axis and having a spherical portion extending radially from the support shaft relative to the axis and straddling a centrally disposed radial axis defining an axially first end side positioned on one side of the radial axis and an axially second end side positioned on an opposite side of the radial axis;an inner tube supporting the spherical portion for rotation on an inner peripheral surface of the inner tube;an outer tube disposed to cover an outside of the inner tube and to form a generally annular space between the inner and outer tubes, the annular space straddling the radial axis so as to extend into both the axially first end side and the axially second end side;a first elastomeric member bonded to an outer peripheral surface of said inner tube and sized and adapted to occupy the annular space on the axially first end side, the first elastomeric member being coupled to the inner peripheral surface of the outer tube on the axially first end side;a second elastomeric member bonded to an inner peripheral surface of the outer tube and sized and adapted to occupy the annular space on the axially second end side, and the second elastomeric member being coupled to the outer peripheral surface of the inner tube on the axially second end side; anda liquid chamber including a liquid encapsulated therein, the liquid chamber defined between the first and second elastomeric members and positioned generally adjacent the radial axis.
