LIQUID SEALED MOUNT

摘要

[Object] To provide a durable liquid-sealed mount that allows a relative displacement between a stud and a housing, i.e., large strokes, has good cushioning properties, has good damping properties by inhibiting cavitation from generating even if high frequency vibration is introduced, and can still absorb small amplitude and high frequency vibration.;[Solving Means] A liquid-sealed mount 1 is attached between a first member and a second member for controlling vibration introduced to the first member or the second member and includes a cup-shaped housing 10, a stud 20, a cap member 30, a diaphragm 40, highly viscous liquid 50, air, a movable damping plate 70, and a support member 80. The support member 80 is positioned between a lower end of the stud 20 or the movable damping plate 70 and the diaphragm 40 and transmits a load in a compression direction applied to the stud 20 to the diaphragm 40.

1. A liquid-sealed mount to be attached between a first member and a second member for controlling vibration introduced to the first member or the second member, characterized in that the liquid-sealed mount comprises:
a cup-shaped housing having an opening at a top, the cup-shaped housing being to be attached to the first member; a stud positioned at a center of the housing in a diameter direction, the stud being to be attached to the second member; a cap member fixed to the opening so as to form a sealed chamber between the cap member and the housing, the cap member holding the stud movably at least in an axial direction of the housing; a diaphragm separating the sealing chamber into a liquid chamber and an air chamber, the air chamber being formed at a bottom of the housing; highly viscous liquid sealed in the liquid chamber; air sealed in the air chamber; a movable damping plate positioned in the liquid chamber, a gap being provided between the movable damping plate and an inner wall of the housing, the liquid being capable of passing through the gap, the movable damping plate being attached to the stud ; and a support member positioned between a lower end of the stud or the movable damping plate and the diaphragm, the support member being configured to transmit a load in a compression direction applied to the stud to the diaphragm.
