Abstract

A hydraulic mount having an upper liquid chamber defined above a nozzle plate mounted therein and a lower liquid chamber defined below the nozzle plate, and configured such that hydraulic liquid filled therein flows through a path defined in the nozzle plate to the upper and lower liquid chambers may include a disc-shaped membrane, and a spring having a shape of a ring into which an edge of the membrane is fitted, and mounted in a mounting recess that is formed in the nozzle plate, in which the spring includes a body portion to which the membrane is fastened, an upper ring portion provided above the body portion, and a lower ring portion provided below the body portion.

First claim

What is claimed is:

1 . A hydraulic mount having an upper liquid chamber defined above a nozzle plate mounted therein and a lower liquid chamber defined below the nozzle plate, and configured such that hydraulic liquid filled therein flows through a path defined in the nozzle plate to the upper and lower liquid chambers, the hydraulic mount comprising:
a disc-shaped membrane; and a spring having a shape of a ring into which an edge of the membrane is fitted, and mounted in a mounting recess that is formed in the nozzle plate, wherein the spring comprises:
a body portion to which the membrane is fastened;
an upper ring portion provided above the body portion; and
a lower ring portion provided below the body portion, a plurality of upper ribs being formed between the upper ring portion and the body portion to be elastically deformed and spaced apart from each other, and a plurality of lower ribs being formed between the lower ring portion and the body portion to be elastically deformed and spaced apart from each other.

2 . The hydraulic mount of claim 1 , wherein each of the upper and lower ribs is disposed to be inclined at a predetermined angle.

3 . The hydraulic mount of claim 2 , wherein the spring comprises a plastic material that is elastically deformable.

4 . The hydraulic mount of claim 2 , wherein each of the upper and lower ribs is formed to have a herringbone pattern where ‘<’ or ‘>’ shapes are continuously formed.

5 . The hydraulic mount of claim 4 , wherein the spring comprises a plastic material that is elastically deformable.

6 . The hydraulic mount of claim 5 , wherein the membrane comprises a rubber material and is manufactured such that a ring-shaped steel plate is embedded therein.

7 . The hydraulic mount of claim 1 , wherein the spring comprises a plastic material that is elastically deformable.
