전술한 목적을 달성하기 위한 본 발명은 크로스멤버; 상기 크로스멤버에 재치되는 재치인슐레이터; 상기 재치인슐레이터에서 상방으로 돌출 형성된 돌출인슐레이터; 상기 돌출인슐레이터에 일체로 형성되며 상기 돌출인슐레이터에서 상방으로 돌출 설치된 볼트; 상기 돌출인슐레이터가 노출되도록 상기 재치인슐레이터를 수용한 채 상기 크로스멤버에 체결되는 캡형엔진마운팅브래킷; 상기 볼트가 끼워진 채 상기 돌출인슐레이터에 재치되는 엔진측 브래킷; 상기 볼트에 체결되는 너트의 구성을 채택 결합하고 있다.The present invention for achieving the above object is a cross member; A mounting insulator mounted on the cross member; A protruding insulator protruding upward from the mounting insulator; A bolt integrally formed in the protruding insulator and protruding upward from the protruding insulator; A cap-type engine mounting bracket fastened to the cross member while receiving the mounting insulator so that the protruding insulator is exposed; An engine side bracket mounted to the protruding insulator while the bolt is fitted; It adopts the structure of the nut fastened to the said bolt.

전술한 구성에서, 상기 재치인슐레이터의 적어도 상하면 중 어느 한 면에는 소정간격마다 절개부가 형성됨으로써, 방진효율을 높일 수 있다.In the above-described configuration, since at least one of the upper and lower surfaces of the mounting insulator is provided with cutouts at predetermined intervals, the dustproof efficiency can be increased.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명하는데, 종래의 것과 동일한 부분은 동일한 참조부호를 부여하고 상세한 설명은 생략한다.Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will now be described with reference to the accompanying drawings, in which like parts are the same as in the prior art, like reference numerals will be omitted.

도 2는 본 발명의 바람직한 실시예에 따른 엔진 마운팅 구조를 도시한 분리 사시도이고, 도 3은 도 2의 결합도이다. 도 2 및 도 3에 도시한 바와 같이, 본 실시예의 엔진 마운팅 구조는 크게 크로스멤버(30), 엔진마운팅인슐레이터(130,140), 캡형엔진마운팅브래킷(120), 엔진측 브래킷(110) 및 체결부재(150a,150b)로 구성된다.2 is an exploded perspective view illustrating an engine mounting structure according to a preferred embodiment of the present invention, and FIG. 3 is a combined view of FIG. 2. As shown in Figures 2 and 3, the engine mounting structure of the present embodiment is largely crossmember 30, the engine mounting insulator (130, 140), the cap engine mounting bracket 120, the engine side bracket 110 and the fastening member ( 150a, 150b).

크로스멤버(30)는 상방으로 절곡된 상부프레임과 하방으로 절곡된 하부프레임으로 구성되어 차체에 고정된다.The cross member 30 is composed of an upper frame bent upwards and a lower frame bent downwards and fixed to the vehicle body.

엔진마운팅인슐레이터(130,140)는 크로스멤버(30)에 재치되는 재치인슐레이터(130)와 재치인슐레이터(130)에서 돌출 형성된 돌출인슐레이터(140)로 구성된다.The engine mounting insulators 130 and 140 include a mounting insulator 130 mounted on the cross member 30 and a protruding insulator 140 protruding from the mounting insulator 130.

돌출인슐레이터(140)는 재치인슐레이터(130)의 중심부에서 상방으로 연장 형성된 것으로, 후술된 엔진측 브래킷(110)이 재치되게 된다. 따라서, 엔진측 브래킷(110)의 상하진동이 돌출인슐레이터(140)를 통해 재치인슐레이터에 전달되게 된다. 이 전달되는 상하진동을 보다 효율적으로 흡수하기 위하여, 재치인슐레이터(130)는 상면과 하면 주위에 절개부(131)(133)가 소정 간격마다 형성되어 있다. 이 절개부(131)(133)로 인해, 재치인슐레이터(130)는 유연성이 향상되어 방진효율을 높일 수 있다.The protruding insulator 140 extends upward from the center of the mounting insulator 130, and the engine side bracket 110 described later is mounted. Therefore, the up and down vibration of the engine side bracket 110 is transmitted to the mounting insulator through the protruding insulator 140. In order to more efficiently absorb the transmitted vertical vibration, the mounting insulator 130 has cutouts 131 and 133 formed around the upper and lower surfaces at predetermined intervals. Due to the cutouts 131 and 133, the mounting insulator 130 may improve flexibility to increase dustproof efficiency.

캡형엔진마운팅 브래킷(120)은 내부에 재치인슐레이터(130)를 수용하고 상부로 돌출인슐레이터(140)가 인출되게 인출공(120a)이 형성되어 있다. 이 캡형엔진마운칭브래킷(120)은 크로스멤버(30)에 체결되어 지지되게 된다.The cap-shaped engine mounting bracket 120 accommodates the mounting insulator 130 therein and has a drawing hole 120a formed therein to protrude the insulator 140 upward. The cap engine mounting bracket 120 is fastened to the cross member 30 to be supported.

한편, 돌출인슐레이터(140)에는 볼트(150a)가 설치되어 있다. 이것은 볼트(150a)를 설치한 상태에서 엔진마운팅인슐레이터를 성형함으로써 제작되게 된다.The protruding insulator 140 is provided with a bolt 150a. This is produced by molding the engine mounting insulator with the bolt 150a installed.

엔진이 장착된 엔진측 브래킷(110)에는 채널 형상으로, 볼트(150a)를 통과할 관통공이 천공 설치되어 있다. 이 관통공을 통해 볼트(150a)에 끼우면 엔진측 브래킷(110)의 하면이 돌출인슐레이터(140)의 상면에 재치되게 된다.The engine-side bracket 110 on which the engine is mounted is provided with a through hole for passing through the bolt 150a in a channel shape. When the bolt 150a is inserted through the through hole, the lower surface of the engine side bracket 110 is placed on the upper surface of the protruding insulator 140.

엔진측 브래킷(110)이 돌출인슐레이터(140)에 재치되면 너트(150a)가 볼트(150a)에 체결됨으로써, 엔진마운팅이 완료되게 된다.When the engine side bracket 110 is mounted on the protruding insulator 140, the nut 150a is fastened to the bolt 150a, thereby completing the engine mounting.

이와 같이, 엔진마운팅인슐레이터를 크로스멤버에 재치시킴으로써 별도의 압입공정이 필요없이 설치가 간단하고 엔진마운팅브래킷의 형상을 단순화시킬 수 있으며, 체결구조가 상하방향에서 이루어져 조립성 작업성에 덜 제약을 받게 된다.As such, by mounting the engine mounting insulator on the cross member, installation is simple and the shape of the engine mounting bracket can be simplified without the need for a separate indentation process. .

It will be apparent to one skilled in the art that this also belongs to the present invention. For example, a functioning member of the insulator can be added between the engine side bracket and the nut.
