Abstract
Official abstract text for this publication.
An object of the present invention is to provide a liquid-charged antivibration device for reducing amplitude dependency. Provided is a liquid-charged antivibration device including: a liquid chamber in which operating liquid is charged; and a partitioning member which partitions the liquid chamber into a main liquid chamber and a sub liquid chamber.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid-charged antivibration device, comprising: a liquid chamber in which operating liquid is charged; and a partitioning member which partitions the liquid chamber into a main liquid chamber and a sub liquid chamber, wherein the partitioning member includes: a first plate disposed on the main liquid chamber side; a second plate disposed on the sub liquid chamber side; and an elastic partitioning member sandwiched between the first plate and the second plate, wherein the elastic partitioning member includes: a thin membrane portion; and a thick membrane portion whose thickness in a direction of a vibration input axis is thicker than that of the thin membrane portion, wherein the second plate includes a restricting portion which restricts elastic deformation of the elastic partitioning member, and wherein the restricting portion includes: a first restricting portion which is disposed so as to face the thick membrane portion and restricts elastic deformation amount of the thick membrane portion; and a second restricting portion which is disposed so as to face the thin membrane portion and restricts elastic deformation amount of the thin membrane portion; wherein the first restricting portion and the second restricting portion are disposed so as to be perpendicular at least partially to each other. 2. The liquid-charged antivibration device according to claim 1 , wherein clearance between the thick membrane portion and the first restricting portion is smaller than clearance between the thin membrane portion and the second restricting portion.
