Description

차량 엔진마운팅용 브라켓의 구조Structure of vehicle engine mounting bracket

본 발명은 차량 엔진마운팅용 브라켓의 구조에 관한 것으로서, 더 상세하게는 차량의 엔진측에 취부되는 엔진마운팅용 브라켓을 실린더헤드의 전면부에 직접 취부되도록하여 브라켓의 크기를 축소시키고, 자체의 내구성을 향상하며 엔진마운팅의 지지를 더욱 견고하게 할 수 있도록한 차량 엔진마운팅용 브라켓의 구조에 관한 것이다.The present invention relates to a structure of a vehicle engine mounting bracket, and more particularly, an engine mounting bracket mounted on an engine side of a vehicle is mounted directly on a front portion of a cylinder head, thereby reducing the size of the bracket and providing durability. It relates to the structure of the vehicle engine mounting bracket to improve the and to make the support of the engine mounting more robust.

일반적으로 차량의 엔진은 섀시프레임 또는 보디에 지지되어 있으며, 엔진의 진동이 섀시나 보디에 전해져 승차감이 나빠지지 않도록 엔진의 장착부에는 반드시 탄성체에 의한 방진장치가 설치되게 된다.In general, an engine of a vehicle is supported by a chassis frame or a body, and a vibration isolator by an elastic body is necessarily installed in the mounting portion of the engine so that vibration of the engine is transmitted to the chassis or the body so that the riding comfort is not deteriorated.

이와 같은 엔진방진장치는 엔진마운팅(Engine Mounting) 또는 엔진서포트라고 부르며, 엔진의 진동이 차체에 전달되지 못하도록 방진기능을 갖게 된다.Such an engine anti-vibration device is called engine mounting or engine support, and has an anti-vibration function to prevent the vibration of the engine from being transmitted to the vehicle body.

이러한 엔진마운팅은 약 160∼295㎏에 달하는 엔진을 지지하기 때문에 차량이 가속하거나 감속함에 따른 회전토오크와 그 반작용을 흡수하고 이를 견디어내도록 엔진에 다수개가 설치되어 엔진에서 발생되는 소음이나 진동을 흡수하게 된다.Since the engine mounting supports an engine weighing about 160 to 295 kg, a plurality of engines are installed in the engine so as to absorb and tolerate rotational torque and its reaction as the vehicle accelerates or decelerates, thereby absorbing noise or vibration generated from the engine. do.

전술한 바와 같은 차량 엔진마운팅 브라켓의 구조는 도 4 및 도 5에 도시된 바와 같이 일측에 실린더블록(1)에 볼트(23) 체결되어 고정되는 플랜지(21)를 가지며, 상기 플랜지(21)를 실린더헤드(2)측으로 연장하여된 타측 상부면에는 엔진마운팅(10) 취부용 볼트부(22)가 돌출형성된 브라켓(20)에 있어서, 상기 브라켓(20)의 볼트부(22)에 엔진마운팅(10)이 너트(11)로 체결되게 된다.The structure of the vehicle engine mounting bracket as described above has a flange 21 fastened to the cylinder block 1 by being fastened to the cylinder block 1 as shown in FIGS. 4 and 5, and the flange 21 is provided. In the bracket 20 in which the engine mounting bolt 10 is mounted on the other upper surface extending to the cylinder head 2 side, the engine mounting is mounted on the bolt portion 22 of the bracket 20. 10) is fastened to the nut (11).

그러나 전술한 바와 같은 차량 엔진마운팅용 브라켓의 구조는 엔진마운팅용 브라켓이 실린더블록에 취부되어 실린더헤드측으로 연장되게 됨에 따라 브라켓의 길이가 과다하게 길어져 강도 및 강성 등이 취약해지며, 이를 보완하기 위해 브라켓의 크기를 확대하면 조립성이 저하되게 된다.However, the structure of the vehicle engine mounting bracket as described above, as the engine mounting bracket is mounted on the cylinder block and extends to the cylinder head side, the length of the bracket is excessively long, which makes the strength and rigidity weak, and to compensate for this. Increasing the size of the bracket will degrade the assembly.

이와 같은 종래 브라켓은 브라켓의 길이가 길어져 자체의 내구성이 약하게 됨에 따라 엔진마운팅의 지지견고성이 저하되게 되고, 또한 조립성 및 차량의 NVH(Noise Vibration Harshness) 성능이 저하되는 문제점이 있다.Such a conventional bracket has a problem that the length of the bracket is long and its durability is weakened, so that the support robustness of the engine mounting is lowered, and the assembly performance and the performance of the vehicle's noise vibration harness (NVH) are deteriorated.

따라서 본 발명은 차량의 엔진축에 취부되는 엔진마운팅용 브라켓을 실린더헤드의 전면부에 직접 취부시켜 브라켓의 크기를 축소시킴과 아울러 엔진마운팅의 지지견고성을 향상시켜 차량의 NVH 성능을 향상되도록한 차량 엔진마운팅용 브라켓의 구조를 제공하는데 그 목적이 있다.Therefore, in the present invention, the engine mounting bracket mounted on the engine shaft of the vehicle is directly mounted on the front of the cylinder head to reduce the size of the bracket and improve the support robustness of the engine mounting to improve the NVH performance of the vehicle. Its purpose is to provide a structure for an engine mounting bracket.

To provide a structure of a vehicle engine mounting bracket, characterized in that consisting of a bracket 30 protruding on the same line at a predetermined interval.

이하, 본 발명의 실시예를 첨부된 예시도면을 참조하여 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 의한 분리 사시도이고, 도 2는 본 발명에 의한 분리단면도, 도 3은 본 발명에 의한 결합단면도이다.Figure 1 is an exploded perspective view according to the present invention, Figure 2 is a separate cross-sectional view according to the present invention, Figure 3 is a combined cross-sectional view according to the present invention.

도시된 바와 같이 실린더헤드(2)의 전면부에 부착되는 커버(40)는 실린더헤드(2)에 용착시켜 고정되도록하되, 이 커버(40)의 전면부에 형성된 홈부(41)는 브라켓(30)의 돌출부(31) 갯수와 동일하게 하고, 또한 돌출부(31)의 위치와 대응되는 위치에 형성하여 브라켓(30)의 돌출부(31)가 끼워져 지지될 수 있도록 한다.As shown in the drawing, the cover 40 attached to the front part of the cylinder head 2 is fixed to the cylinder head 2 by being fixed, but the groove part 41 formed in the front part of the cover 40 is bracket 30 The number of protrusions 31) is the same as that of the protrusions 31 and is formed at a position corresponding to the position of the protrusions 31 so that the protrusions 31 of the bracket 30 can be fitted and supported.

상기 브라켓(30)의 돌출부(31)는 3개로 하며, 이 브라켓(30)의 돌출부(31)가 끼워지는 커버(40)의 홈부(41) 역시 상기 돌출부(31)와 동일 갯수를 갖도록 한다.The protrusions 31 of the bracket 30 are three, and the grooves 41 of the cover 40 to which the protrusions 31 of the bracket 30 are fitted have the same number as the protrusions 31.

상기 브라켓(30) 일측방 상부면에 돌출된 스터드볼트(32)는 소정의 간격을 갖고 동일선상에 돌출되게 한다.The stud bolt 32 protruding from one side upper surface of the bracket 30 has a predetermined interval so as to protrude on the same line.

상기와 같은 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention as described above are as follows.

엔진실린더블록(1) 상부의 실린더헤드(2) 전면부에 다수의 홈부(41)를 갖는 커버(40)를 용착하여 부착시킨후, 상기 커버(40)의 홈부(41)에 브라켓(30)의 돌출부(31)를 각각 끼워 고정시킨다.After the cover 40 having a plurality of grooves 41 is welded and attached to the front of the cylinder head 2 above the engine cylinder block 1, the bracket 30 is attached to the groove 41 of the cover 40. The protrusions 31 of the fitting are respectively fixed.

이와 같이 커버(40)의 홈부(41)에 브라켓(30)의 돌출부(31)가 끼워져 고정되게 되면, 브라켓(30)의 위치는 엔진마운팅(10)이 취부되는 실린더헤드(2)의 측면에 위치되게 된다.When the protrusion 31 of the bracket 30 is fitted into the groove 41 of the cover 40 in this manner, the bracket 30 is positioned on the side of the cylinder head 2 on which the engine mounting 10 is mounted. To be located.

전술한 바와 같이 실린더헤드(2) 측면으로 브라켓(30)이 위치된 상태에서 상기 브라켓(30)의 일측방 상부면에 돌출되어진 스터드볼트(32)에 엔진마운팅(10)을 취부시키게 되는데 그 취부는 다음과 같다.As described above, the engine mounting 10 is mounted on the stud bolt 32 protruding from the upper surface of the bracket 30 in the state in which the bracket 30 is positioned on the side of the cylinder head 2. Is as follows.

브라켓(30)의 스터드볼트(32) 상부로 엔진마운팅(10)은 끼운후 너트(11)를 체결하게 되면 브라켓(30)의 스터드볼트(32)에 엔진마운팅(10)이 견고하게 취부되게 된다.When the engine mounting 10 is inserted into the stud bolt 32 of the bracket 30 and the nut 11 is fastened, the engine mounting 10 is firmly mounted to the stud bolt 32 of the bracket 30. .

상기와 같은 본 발명의 차량 엔진마운팅용 브라켓의 구조는 엔진마운팅 취부용 브라켓이 실린더헤드에 측면에 직접 취부되게 됨에 따라 브라켓의 길이 및 크기가 전체적으로 축소되어 코스트가 절감되고, 조립성이 향상될뿐아니라 자체의 내구성이 향상되어 엔진마운팅의 지지견고성이 향상되게 된다. 그러므로 엔진의 지지견고성이 더욱 확실하게 이루어져 차량의 NVH 성능이 향상되는 효과가 있다.As the structure of the vehicle engine mounting bracket of the present invention as described above is directly mounted on the side of the engine mounting bracket to the cylinder head, the length and size of the bracket is reduced as a whole to reduce the cost, and improves assembly In addition, the durability of the engine itself is improved, and thus the supporting rigidity of the engine mounting is improved. Therefore, the firmness of the engine is more securely achieved, which has the effect of improving the vehicle's NVH performance.
