Abstract

An engine mount may include: a support device; a bracket device; and a vibration proof device which connects the support device and the bracket device, and, in which the vibration proof device may include a nozzle device fastened to the support device, and has a nozzle plate dividing an internal space of the vibration proof device into a first liquid chamber and a second liquid chamber, and a flow path penetrating the nozzle plate; a first insulator defining the first liquid chamber together with the nozzle plate; a first core protruding from the first insulator toward one side, and fastened to the bracket device; a second insulator defining the second liquid chamber together with the nozzle plate; and a second core protruding from the second insulator and fastened to the bracket device.

First claim

What is claimed is:

1. A method of manufacturing an engine mount, which includes a support device that is fastened to an engine, a bracket device that is fastened to a vehicle body, and a vibration proof device that connects the support device and the bracket device, the method comprising:
manufacturing the bracket device or the support device having a vibration proof device fastening portion on which the vibration proof device is disposed and a plurality of protruding portions which is spaced from each other with a gap therebetween and outwardly protrudes from an external circumferential surface of the vibration proof device fastening portion by an extrusion process;
manufacturing the bracket device having side brackets by the extrusion process;
forming a stopper on the external circumferential surface of the vibration proof device fastening portion by a curing process;
inserting the vibration proof device into an internal circumference of the vibration proof device fastening portion; and
fastening the vibration proof device, which is inserted into the vibration proof device fastening portion, to the bracket device,
wherein the fastening the vibration proof device, which is inserted into the vibration proof device fastening portion, to the bracket device includes locating the side brackets between the protruding portions.

2. The method of claim 1 , wherein the manufacturing of the support device and the bracket device by the extrusion process manufactures each of the support device and the bracket device by an aluminum extrusion method.

3. The method of claim 1 , wherein the forming of the stopper on the external circumferential surface of the vibration proof device fastening portion by the curing process includes attaching the stopper to the external circumferential surface of the vibration proof device fastening portion by the curing process.
