20090026672 | Vibration damping device equipped with rubber heat-insulating cover - A vibration damping device having a rubber heat-insulating cover wherein the rubber heat-insulating cover is formed as a separate component from a stopper member and is disposed between the stopper member and a main rubber elastic body connecting a first and second mounting member. The rubber heat-insulating cover is fixed to the stopper member with a center section of the rubber heat-insulating cover juxtaposed from an inner face side against a strike plate portion of the stopper member to be supported by the strike plate portion. With a peripheral wall section of the rubber heat-insulating cover juxtaposed from the inner face side against leg portions of the stopper member to be supported by the leg portions. A cushioning rubber is integrally formed with the center section of the rubber heat-insulating cover supported on the strike plate portion, and projects towards the first mounting member. | 01-29-2009 |
20090026675 | Vibration damping device equipped with rubber heat-insulating cover - A vibration damping device having a rubber heat-insulating cover wherein a strike plate portion and a pair of leg portions of a stopper member have detaining slots opening towards an outside, and two side walls of the detaining slot of the strike plate portion has stepped portions of notched shape disposed in its heightwise distal edge section. Center hook portions are formed on an outside face of a center section of the rubber heat-insulating cover, while outside hook portions are formed on an outside face of a peripheral wall portion of the rubber heat-insulating cover. The center hook portions are engaged with the two side walls of the detaining slot, and the outside hook portions are engaged with the two side walls of the detaining slots in the leg portions. Two end faces of the center hook portions are held in abutment against stepped faces at either end of the stepped portions in both side walls of the detaining slot. | 01-29-2009 |
20090140476 | Fluid filled type vibration damping device - A fluid filled type vibration damping device including: a partition member having a communication passage connecting a pressure receiving and equilibrium chambers; an obstructing rubber elastic plate juxtaposed against the communication passage from a pressure receiving chamber side, adapted to obstruct the communication passage, and arranged to be exposed to pressure of the pressure receiving and the equilibrium chamber at both faces; and a constraining member provided for retaining an outer peripheral section of the obstructing rubber elastic plate in contact against the partition member at multiple locations. The constraining member provides an opening/closing control member operated to induce the obstructing rubber elastic plate to push against the partition member and close off the communication passage, and to induce elastic deformation of the obstructing rubber elastic plate to be separated from the partition member. | 06-04-2009 |
20100102495 | Fluid filled type vibration damping device - A fluid filled type vibration damping device including an elastic rubber body elastically connecting an inner shaft member and an outer tube member. The elastic rubber body has a solid rubber wall that includes inside face recesses and outside face recesses respectively formed to either side of the inner shaft member in an axis-perpendicular direction so that a pair of thin portions and a pair of thick portions respectively situated in opposition along mutually orthogonal axes lying in axis-perpendicular directions are formed in the solid rubber wall. A deepest part of the inside face recesses is situated towards an axial small diameter side of the solid rubber wall with respect to an deepest part of the outside face recesses, with the inside face recesses and the outside face recesses overlapping one another in the axis-perpendicular direction of the solid rubber wall. | 04-29-2010 |
20100201053 | FLUID FILLED TYPE VIBRATION DAMPING DEVICE - A fluid filled type vibration damping device including: an obstructing rubber elastic plate disposed so as to obstruct a communication aperture that connects a pressure receiving chamber and an equilibrium chamber; contact retaining portions arranged on an outer peripheral edge of the rubber plate and held in contact against a partition member; an elastic deformation zone arranged circumferentially between the contact retaining portions of the rubber plate so as to undergo elastic deformation on a basis of pressure differential between the pressure receiving chamber and the equilibrium chamber to be spaced away from the partition member to cause the aperture to open up; and a non-linearizing member provided such that the elastic characteristics of the elastic deformation zone become more rigid in a non-linear manner in association with increase in an amount of its deformation. | 08-12-2010 |
20150041617 | MOUNTING MEMBER FOR VIBRATION DAMPING DEVICE AND VIBRATION DAMPING DEVICE USING THE SAME - A mounting member for use in a vibration damping device equipped with a main rubber elastic body and a bracket, including: a fixing member configured to be fixed to the bracket; an anchoring member made of resin and configured to be anchored to the main rubber elastic body. The anchoring member is anchored to the fixing member and protrudes from the fixing member. | 02-12-2015 |
20150069686 | FLUID-FILLED VIBRATION DAMPING DEVICE - A fluid-filled vibration damping device including: a pressure-receiving chamber; an equilibrium chamber; a partition member having a communication aperture through which the two chambers communicate; and an elastic rubber plate superposed to cover the communication aperture from a pressure-receiving chamber side. The elastic rubber plate includes one or more contact retaining portions that are provided on an outer peripheral edge thereof and retained in contact against the partition member, and a deformation-allowing region that is provided between circumferentially opposite ends of one or two of the contact retaining portions of the elastic rubber plate and that is elastically deformable based on pressure differential between the two chambers. A gap is formed between the deformation-allowing region and the partition member so that a communication passage is constituted by including the gap through which the two chambers communicate with each other. | 03-12-2015 |
20150219178 | FLUID-FILLED VIBRATION DAMPING DEVICE - A fluid-filled vibration damping device including a main rubber elastic body composed of a first rubber elastic body and a second rubber elastic body which are overlapped in an axial direction, and a pair of axis-perpendicular liquid chambers formed between the first and second rubber elastic bodies. A pair of dividing walls which divide the axis-perpendicular liquid chambers are constituted by a first division piece protruding from the first rubber elastic body and a second division piece protruding from the second rubber elastic body being overlapped in a circumferential direction. The first rubber elastic body has a thickness, diameter and spring constant all set larger than those of the second rubber elastic body, while having a tapered shape. With the device mounted on a vibration transmission system, a static support load is input so as to compress the first rubber elastic body. | 08-06-2015 |
