Liquid sealed mount

摘要

A hydraulic mount includes: a container in which a high-viscosity fluid is liquid-tightly sealed; a rubber mount that is provided on an upper side of the container; a rod that slidably penetrates through the rubber mount; a damper plate that is provided to an end of the rod; a damping force generator that is provided by a clearance between the container and the damper plate; a main fluid chamber that includes an upper fluid chamber and a lower fluid chamber provided by dividing an interior of the container by the damper plate; a volume-variable secondary fluid chamber that communicates with the main fluid chamber; and a pressurizer that generates a differential pressure between the upper fluid chamber and the lower fluid chamber during the movement of the rod.

1. A hydraulic mount comprising:
a container configured to liquid-tightly seal a high-viscosity fluid therein; a rubber mount that is provided on an upper side of the container; a rod that is configured to move reciprocatively relative to the high-viscosity fluid in the container, the rod being configured to move slidably relative to the rubber mount; a damper plate that is provided to an end of the rod and located in a portion of the container that contains the high-viscosity fluid, the damper plate including an outer circumferential surface that is fully continuous along an entire circumference of the damper plate and is opposed to and spaced apart from an inner circumferential surface of the container, a fully continuous and circumferential clearance being defined between the outer circumferential surface and the inner circumferential surface to provide a flow path for the high-viscosity fluid, wherein the damper plate is continuous such that a downward movement of the damper plate causes the high-viscosity fluid vertically below the damper plate to flow through the clearance, the flow of the high-viscosity fluid through the clearance generating a damping force; a main fluid chamber that includes an upper fluid chamber and a lower fluid chamber provided by vertically dividing an interior of the container by the damper plate; and a pressurizer that is configured to move in accordance with a movement of the high-viscosity fluid in the main fluid chamber based on an axial movement of the rod to thereby correspondingly pressurize the sealed high-viscosity fluid so that the pressurized high-viscosity fluid moves to the upper fluid chamber through the clearance.
