Description

자동차의 엔진마운팅 브라켓트{Engine Mounting Bracket of a Vehicle} Engine Mounting Bracket of Vehicle

본 발명은 자동차의 엔진마운팅을 견고하게 설치할 수 있도록 하는 자동차의 엔진마운팅 브라켓트에 관한 것으로, 더 자세하게는 엔진마운팅을 엔진마운팅브라켓에 견고히 결합시키는 것이 용이하게 이루어지도록 함과 동시에 사이드멤버와 펜다 에이프런의 강성이 동시에 향상되도록 하는 자동차의 엔진마운팅 브라켓트에 관한 것이다.The present invention relates to an engine mounting bracket of a vehicle that enables to firmly install the engine mounting of the vehicle, and more particularly, it is easy to firmly combine the engine mounting to the engine mounting bracket and at the same time the side member and the fender apron The present invention relates to an engine mounting bracket of a vehicle to increase rigidity at the same time.

일반적으로 자동차에는 엔진이 가동시 발생되는 진동을 흡수하도록 고무로 만들어진 러버마운팅이나 고무 내에 액체를 봉입하여 진동의 감쇄력을 크게 한 액체봉입 엔진마운팅등을 브라켓트를 이용해 설치 함으로서, 상기 엔진에서 발생된 진동이 엔진마운팅에서 흡수되어 차체에 전달되지 않도록 하고 있다.In general, automobiles are provided with rubber mounting rubber mountings to absorb vibrations generated when the engine is running, or liquid-filled engine mountings having a liquid damping force by enclosing liquid in rubber, using brackets, thereby generating vibrations generated by the engine. It is absorbed by the engine mountings and is not transmitted to the bodywork.

여기에서 종래 자동차의 엔진마운팅 브라켓트는 도 1에 도시하고 있는 바와 같이, 사이드멤버(400)에 볼트(500) 체결되며 결합되는 지지부(210)가 좌우 양측에 형성되고, 상기 지지부(210)와 지지부(210) 사이에는 엔진마운팅(100)의 외통부(110)가 억지 압입되어 결합되는 파이프형상의 엔진마운팅외통결합부(220)가 형성되며, 상기 엔진마운팅외통결합부(220)의 일측부에는 일측단부가 펜다 에이프런(300)에 볼트(500) 체결되는 연결부재(230)가 형성되어 있다. Here, the engine mounting bracket of the conventional vehicle, as shown in Figure 1, the support member 210 is fastened to the side member 400 is coupled to the bolt 500 is formed on both left and right sides, the support portion 210 and the support portion Between the 210 is formed a pipe-shaped engine mounting outer cylinder coupling portion 220 is coupled to the outer cylinder portion 110 of the engine mounting 100 is pressed by force, one side of the engine mounting outer cylinder coupling portion 220. An end portion of the fender apron 300 is formed with a connecting member 230 fastened to the bolt 500.

이러한 종래 자동차의 엔진마운팅 브라켓트(200)는 좌우 양측에 형성된 지지부(210)와 일측부에 형성된 연결부재(230)가 각각 사이드멤버(400)와 펜다 에이프런(300)에 볼트(500) 체결되며 결합되어 있는 엔진마운팅외통결합부(220)에 엔진마운팅(100)의 외통부(110)가 억지 압입되는 것에 의해, 상기 엔진마운팅(100)이 엔진을 지지하면서 엔진에서 발생되는 기진력을 절연시키도록 하고 있다.The engine mounting bracket 200 of the conventional vehicle is coupled to the bolts 500 fastened to the side members 400 and the fender apron 300 by the support members 210 formed on the left and right sides and the connection members 230 formed on one side thereof, respectively. When the outer cylinder portion 110 of the engine mounting 100 is forcibly pressed into the engine mounting outer cylinder coupling portion 220, the engine mounting 100 supports the engine to insulate the vibration force generated in the engine. have.

그러나 이러한 종래 자동차의 엔진마운팅 브라켓트(200)는 엔진마운팅외통결합부(220)에 엔진마운팅(100)을 억지 압입시키는 것이 어렵게 이루어지게 됨으로서, 차량을 조립시 작업자가 많은 작업시간을 필요로 하게 됨은 물론, 상기 엔진마운팅외통결합부(220)가 지지부(210)와 연결부재(230)가 각각 사이드멤버(400)와 펜다 에이프런(300)에 볼트(500) 체결되는 것에 의해서만 엔진마운팅(100)을 지지함으로서, 차량의 좌우 방향으로 강성이 부족하고, 차량의 상하방향에 대한 좌우 방진기능이 미약하여 심한 소음을 유발시키게 되는 문제점이 있었다.However, the engine mounting bracket 200 of such a conventional vehicle is difficult to forcibly press-fit the engine mounting 100 to the engine mounting outer cylinder coupling portion 220, so that the operator requires a lot of working time when assembling the vehicle. Of course, the engine mounting outer cylinder coupling part 220 supports the engine mounting part 100 only by fastening the bolts 500 to the side member 400 and the fender apron 300, respectively. By supporting, there was a problem in that the rigidity in the left and right direction of the vehicle is insufficient, the left and right dustproof function in the vertical direction of the vehicle is weak, causing severe noise.

본 발명의 목적은 상기 종래와 같은 문제점을 해결하기 위해 펜다 에이프런과 사이드멤버에 저면이 접하며 용착되는 용착부가 브라켓트의 외측으로 절곡 연장되어 일체로 형성되고, 상기 브라켓트의 상부에는 엔진마운팅이 인입되는 인입홈이 내삽지게 형성되며, 상기 브라켓트의 상부면에는 엔진마운팅의 외통부가 볼트 체결되는 체결공이 소정의 간격을 두고 복수개 형성되어, 엔진마운팅의 하중, 진동방향이 브라켓트의 안착홈과 동일선상에 위치하게 되므로 300Hz이상에서도 차량의 상하방향에 대한 피크가 발생하지 않게 되어 소음이 획기적으로 저감되고, 사이드멤버에 2점 펜다 에이프런에 1점이 체결되는 형태였던 종래 구조와는 달리 사이드멤버와 펜다 에이프런이 브라켓트의 용착부가 용착되는 것에 의해 강성이 증대되도록 함과 동시에, 상기 브라켓트의 인입홈에 엔진마운팅이 결합되어 있는 외통부를 삽입시킨 후 볼트 체결시키는 것에 의해 상기 엔진마운팅이 고정되게 브라켓트에 결합됨으로서, 차량을 조립시 엔진마운팅을 정확한 위치에 쉽고 편리하게 조립시킬 수 있도록 하는 자동차의 엔진마운팅 브라켓트를 제공하는 데에 있는 것이다.An object of the present invention is to contact the bottom of the fender apron and the side member to solve the same problem as the conventional welded portion is formed integrally by bending extended to the outside of the bracket, the engine mounting is introduced into the upper portion of the bracket The groove is formed to be interpolated, and a plurality of fastening holes for bolting the outer cylinder portion of the engine mounting are formed at predetermined intervals on the upper surface of the bracket, so that the load and vibration direction of the engine mounting are on the same line as the seating groove of the bracket. Therefore, the peak in the vertical direction of the vehicle does not occur even above 300 Hz, the noise is drastically reduced, and unlike the conventional structure in which one point is fastened to the two-point fender apron on the side member, the side member and the fender apron are As the welded portion is welded, the rigidity is increased and at the same time, The engine mounting is fixed to the bracket by fastening the bolt after inserting the outer cylinder portion in which the engine mounting is coupled to the inlet groove of the bracket, so that the engine mounting can be easily and conveniently assembled at the correct position when assembling the vehicle. It is to provide the engine mounting bracket of the car.
