Hydraulic mount for vehicle

摘要

Disclosed herein is a hydraulic mount for a vehicle, wherein a serpentine wall that protrudes from a bottom surface of a membrane wherein the membrane operates as a bottom surface of the upper chamber, is bonded to an orifice lower plate and separates a central chamber and a serpentine inertia track. Furthermore, the serpentine inertia track is disposed along a circumference of the central chamber. The hydraulic mount additionally includes a plurality of orifice apertures that are formed in the orifice lower plate and configured to allow communication between the central chamber and the lower chamber.

1. A hydraulic mount for a vehicle, comprising:
an insulator configured to form an upper chamber; a diaphragm disposed on a bottom surface of the insulator and configured to form a lower chamber; an orifice lower plate disposed on a top surface of the diaphragm; a membrane disposed on a top surface of the orifice lower plate, wherein the orifice lower plate is disposed between the membrane and the diaphragm; a serpentine wall that protrudes from a bottom surface of the membrane wherein the membrane is configured to operate as a bottom surface of the upper chamber, and the serpentine wall is bonded to the orifice lower plate; a central chamber formed between the membrane and the orifice lower plate; a serpentine inertia track disposed along a circumference of the central chamber, wherein the serpentine wall is configured to separate the central chamber from the serpentine inertia track; and a plurality of orifice apertures formed in the orifice lower plate and configured to allow communication between the central chamber and the lower chamber, wherein a top surface and sidewall of the orifice lower plate and the serpentine wall of the membrane form the inertia track which is a serpentine fluid path between the upper chamber and the lower chamber, and wherein a first fluid hole is formed in one side of the membrane to allow communication between the upper chamber and the inertia track, and a second fluid hole is formed in one side of the orifice lower plate that forms the inertia track to allow communication between the inertia track and the lower chamber.
