Abstract

The present disclosure provides an engine mount for a vehicle. The engine mount includes a rubber assembly that is connected between a vehicle body and an engine. A fluid sealing assembly is detachably assembled to the rubber assembly, allowing tuning of the engine mount to be performed by detaching the fluid sealing assembly while the engine remains connected to the engine mount.

First claim

What is claimed is:

1. An engine mount for a vehicle, comprising:
a rubber assembly having a rubber housing; and
a fluid sealing assembly having a fluid housing which is detachably inserted into the rubber housing of the rubber assembly,
wherein the fluid sealing assembly is configured to be detached from an upper part of the rubber assembly for tuning the engine mount,
wherein the rubber housing is configured to be connected between a vehicle body and an engine,
wherein an upper part of the rubber housing is open, and
wherein the rubber assembly includes a first main rubber vulcanized on a bottom surface of the rubber housing while surrounding a first core having a core bolt.

2. The engine mount for the vehicle of claim 1 , wherein an inner diameter surface of the rubber housing includes a locking guide groove which extends downward from a top end of the rubber housing and a locking aperture which extends in a perpendicular direction from a lower end of the locking guide groove.

3. The engine mount for the vehicle of claim 1 , wherein the core bolt protrudes from a bottom of the rubber housing to be coupled to a vehicle body mounting bracket.

4. The engine mount for the vehicle of claim 1 , wherein an outer diameter surface of the rubber housing is protrudedly provided with a coupling end which is coupled to an engine mounting bracket.

5. An engine mount for a vehicle, comprising:
a rubber assembly having a rubber housing; and
a fluid sealing assembly having a fluid housing which is detachably inserted into the rubber housing of the rubber assembly,
wherein the fluid sealing assembly is configured to be detached from an upper part of the rubber assembly for tuning the engine mount,
wherein the rubber housing is configured to be connected between a vehicle body and an engine, and
wherein the fluid sealing assembly includes:
a fluid housing detachably inserted through an upper opening of the rubber housing;
a diaphragm disposed at an upper end inside the fluid housing to maintain air tightness of an upper side of a fluid;
an orifice structure having a fluid flow path in a vertical direction and stacked on a bottom part of the diaphragm;
a membrane stacked at an opening of a center of the orifice structure to separate an upper fluid chamber and a lower fluid chamber; and
a second main rubber having an outer circumferential surface that adheres to an inner diameter surface of the fluid housing while an edge part of an upper surface is stacked and supported on an edge of a bottom surface of the orifice structure to maintain air tightness of a lower side of the fluid and having a bottom surface that abuts an upper surface of a first main rubber of the rubber assembly.

6. The engine mount for the vehicle of claim 5 , wherein a lower end part of the fluid housing is integrally formed with a plurality of hooks which are locked to an edge of a bottom surface of the second main rubber.

7. The engine mount for the vehicle of claim 5 , wherein an edge part of the second main rubber includes a second core, and a lower end part of the second core protrudes through a bottom surface of the second main rubber to include an object to which a plurality of hooks are locked.

8. The engine mount for the vehicle of claim 5 , wherein an outer diameter surface of the fluid housing is integrally formed with a locking protrusion that slides along a locking guide groove of the rubber housing and then is inserted into a locking aperture.

9. The engine mount for the vehicle of claim 5 , wherein an outer surface of the fluid housing includes a handle which rotates the fluid housing in a locking or unlocking direction.
