An outer attachment member (111) includes a first end member (117), a second end member (118), and an intermediate member (116), in which the first end member (117) and the second end member (118) are respectively fitted into both end portions of the intermediate member (116) in the axial direction, a coupled portion (135) provided in any one of the vibration generating part and the vibration receiving part is disposed on one end surface of both end surfaces of the first mounting projecting portion (124) in the axial direction provided in the intermediate member (116), and a second mounting projecting portion (125) is disposed on the other end surface thereof, the first mounting projecting portion (124) and the second mounting projecting portion (125) are separately provided with insertion holes (111a) through which fixing bolts (136) for integrally fixing the first mounting projecting portion (124) and the second mounting projecting portion (125) and for coupling the first mounting projecting portion (124) to the coupled portion (135) are inserted, a first crimping portion (128) and a second crimping portion (129) for separately crimping the first end member (117) and the second end member (118) is formed at both end portions of the intermediate member (116) in the axial direction, and the circumferential length of the first crimping portion (128) is larger than the circumferential length of the second crimping portion (129).

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 vibration damping device (10) comprises a tubular outer attachment member (11) and an inner attachment member (12); a pair of main rubber portions (13) that couple the outer attachment member (11) to the inner attachment member (12), and that are arranged so as to be spaced in an axial direction along a central axis (O) of the outer attachment member (11); and a partition portion (15) that couples the outer attachment member (11) to the inner attachment member (12), and that partitions a liquid chamber (25) between the pair of main rubber portions (13), in the axial direction, into a first liquid chamber (26) and a second liquid chamber (27). The partition portion (15) comprises an annular rigid portion (30) in which a restricted passage (33) that connects the first liquid chamber (26) to the second liquid chamber (27) is formed, and an annular elastic portion (29) that is adjacent to the rigid portion (31) in the radial direction. The elastic portion (29) is compressed and deformed in the radial direction and makes contact with the rigid portion (30) in an unbonded state.

A hydraulic body mount with a combined rubber cushion and a hydraulic module may include an inner shaft, a mounting plate, a mounting bracket, a main rubber element, an inner ring, a fluid track, an upper bellows, a washer, a lower bellows, an outer can, a rate plate, a lower bushing, a crash washer, a doubler plate, and a retainer bracket. The fluid track may be configured to receive a fluid via a fluid port. The upper and/or lower bellows may be configured to interact with the fluid. The rate plate may be configured to engage the lower bushing and may be deformed when receiving the at least a portion of the inner shaft.

A fluid mount for a vehicle includes a main bush mounted on an outer circumferential surface of an inner pipe and to which an outer pipe is coupled so that a fluid-contained internal region is sealed, and a middle bush dividing the internal region into a front liquid chamber and a rear liquid chamber and configured to, when vibration is generated along an axial direction of the inner pipe, form a fluid path extending a vibration-generating direction to allow the fluid to selectively flow from the front liquid chamber to the rear liquid chamber or from the rear liquid chamber to the front liquid chamber in the internal region.
