摘要： A fluid-filled type vibration damping device including a base component and a tubular mating component. The tubular mating component is externally fitted onto the base component by means of a diameter-constricting caulking with a sealing rubber clasped therebetween so as to constitute a mate-fastened portion. The tubular mating component extends axially outward beyond a sealed section of the mate-fastened portion so as to provide a caulking tube portion. A diametrical position of the tubular mating component at the sealed section is determined by contact of the caulking tube portion against an outside peripheral face of a positioning projection provided on the base component so as to define a diametrical positioning portion. The caulking tube portion is constricted in diameter and held in engagement with an axial edge portion of the positioning projection so as to form an axial positioning portion.

摘要： A fluid-filled type vibration-damping device having a movable rubber plate housed within a partition member partitioning a pressure-receiving chamber and an equilibrium chamber from each other. The movable rubber plate is moved owing to the pressure difference between the two chambers. The movable rubber plate comprises the movable rubber plate formed of a generally disk shaped rubber elastic body having formed thereon in alternating fashion concave grooves and convex ribs each extending in a circumferential direction about a same center axis, the convex ribs have tapered cross section gradually narrowing in width towards an distal end thereof, and the concave grooves and convex ribs are disposed at the same locations in a diametrical direction on either face of the movable rubber plate so that the thickness of the movable rubber plate is varied in the circumferential direction.

摘要： A fluid-filled type active vibration damping device including a vibration damping device main unit, an oscillation member, and an actuator. The actuator is constituted by an electromagnetic actuator having a stator that includes a coil fixed to a second mounting member while having a movable member linearly displaceable relative to the stator when the coil is energized. A shaft member is provided for connecting the movable member and the oscillation member with each other. A connecting portion is provided for attaching the shaft member to the movable member while permitting the shaft member to tilt as well as to undergo displacement in an axis-perpendicular direction with respect to the movable member. A displacement preventing portion is provided for fastening the movable member and the shaft member to each other by preventing tilt as well as displacement in the axis-perpendicular direction due to the connecting portion.

摘要： A second bush of a torque rod is fastened and fixed such that a mating fastening member sandwiches an inner fitting in the axial direction. A rubber stopper on an acceleration side projecting from an outer fitting to the inner fitting is provided such that the rubber thickness increases toward a front end. The inner fitting is provided with a stopper contact forming a recessed space in which the rubber stopper is inserted. After the rubber stopper comes in contact with the stopper contact in a stopper function, the rubber stopper is deformed so as to fill the recessed space, and concurrently bulges in the axial direction to come in contact with the mating fastening member.

摘要： A fluid filled type vibration damping device having a pressure-receiving chamber and an equilibrium chamber disposed on either side of a partition member. A movable cover member juxtaposed against the partition member from the pressure receiving chamber side to cover a communicating hole of the partition member. An outside peripheral edge of the movable cover member is held in intimate contact against the partition member through urging force of an elastic retainer portion. Pressure of both chambers will acts on both faces of a movable rubber film, thereby constituting a pressure fluctuation absorbing mechanism. The outside peripheral edge of the movable cover member is separated from the partition member in opposition to the urging force by negative pressure in the pressure receiving chamber for providing a shunting mechanism for preventing excessive negative pressure in the pressure receiving chamber.
