    摘要: A hydraulic damping device is provided including a housing having a first main liquid chamber defined in part by a rubber body which expands and contracts upon input of vibrations in a vertical direction, a second main liquid chamber defined in part by a rubber body which expands and contracts upon input of vibrations in a horizontal direction, and an auxiliary liquid chamber defined in part by a rubber film, which communicates with the first and second main liquid chambers through passageways. Upon input of vibrations in a vertical direction, one or more valves opens the passageway communicating with the first main liquid chamber and closes the passageway communicating with the second main liquid chamber to force a damping liquid filled within the first main liquid chamber to flow into the auxiliary liquid chamber, thereby damping vibrations in a vertical direction. Upon input of vibrations in a horizontal direction, the valve(s) closes the passageway communicating with the first main liquid chamber and opens the passageway communicating with the second main liquid chamber to force the damping liquid within the second main liquid chamber to flow into the auxiliary liquid chamber, thereby damping vibrations in a horizontal direction.

    摘要: A hydraulic damping device is provided having a rubber elastic body, a rubber film member closing an opening of the rubber elastic body so as to define a closed chamber, and a partition member dividing the closed chamber into two liquid chambers. A restricted liquid passageway interconnects the two liquid chambers. A cylindrical frame member composed of a resin material having a low coefficient of thermal conductivity is joined to the outer peripheral surface of the rubber elastic body. A support member composed of an aluminum alloy is secured to the outer peripheral surface of the frame member and is connected to an engine. When the support member receives a large amount of heat from the engine, the rubber elastic body is thermally insulated from the support member by virtue of the resin frame member, and accordingly, can be prevented from deteriorating due to the heat of the engine. In addition, by composing the support member of an aluminum alloy, the weight of the device can be reduced.

    摘要: In a vibration wave driven motor, an elastic body of an elliptic shape is provided where different degrees of stiffness or rigidity are available with the arcuate portions and the straight portions, and the ratio between the distortion energy and the vibration energy that part in the generation of the natural frequency for the A vibration mode is arranged virtually equal to that ratio for the B vibration mode, thus enabling the matching of frequencies for both A and B modes.

    摘要: A vibration-damping device with hydraulic damping has a base body, a cylindrical holder secured to the base body, and an outer cylinder press-fitted within the cylindrical holder. A vibration-damping rubber body provided with a main liquid chamber enclosing a damping liquid is disposed within the outer cylinder, and retains an inner cylinder. A thin rubber wall is disposed between the outer cylinder and the vibration-damping rubber body, and defines an auxiliary liquid chamber with the vibration-damping rubber body. This auxiliary liquid chamber communicates with the main liquid chamber by way of a throttled passageway. The cylindrical holder has a rib-like projection which radially outwardly project therefrom, and extends in a circumferential direction thereof. This projection defines a groove along an inner surface of the cylindrical holder. This groove communicates with a space defined by the outer cylinder and the thin rubber wall by way of a through hole formed in the outer cylinder, whereby the thin rubber wall freely deforms due to the flow of the damping liquid from the main liquid chamber to the auxiliary liquid chamber, and accordingly, effective vibration-damping operation can be performed.
