Description

엔진지지용 액체봉입 마운팅장치Liquid Filling Mounting Device for Engine Support

본 고안은 엔진지지용 액체봉입 마운팅장치에 관한 것이다.The present invention relates to a liquid loading mounting device for supporting the engine.

운전중의 엔진은 피스톤과 컨로드의 상하운동에 의한 중심위치의 주기적 변화가 일어나고, 실린더 축방향으로 생기는 왕복운동 부분의 관성력 발생과 커넥팅로드가 크랭크축의 좌우로 흔들리는 것에 의한 관성력 및, 크랭크축에 가해지는 회전력의 주기적 변환에 의해 항상 진동이 발생한다.During operation, the engine periodically changes its center position due to the up and down movement of the piston and the conrod, and the inertia force generated by the reciprocating part in the cylinder axial direction and the inertia force caused by the connecting rod swinging to the left and right of the crankshaft and the crankshaft The vibration always occurs due to the periodic change of the applied torque.

이러한 진동은 실린더수가 적은 엔진이 실린더수가 많은 엔진보다 또 저속회전시에는 고속회전시보다 진동이 커지게 되는 바, 프레임 또는 바디에 지지된 자동차용 엔진의 진동이 샤시나 바디에 전해져 승차감이 나빠지지 않도록 엔진장착부에는 반드시 탄성체에 의한 방진장치가 설치되어 있다.These vibrations are higher in engines with fewer cylinders than in engines with many cylinders and at higher speeds than at high speeds, and the vibrations of automobile engines supported by the frame or body are transmitted to the chassis or body, resulting in poorer riding comfort. In order to prevent this, the engine mounting part is necessarily provided with a dustproof device by an elastic body.

일반적으로 엔진 마운팅장치는 고무 등의 완충제를 거쳐서 엔진쪽과 차체바디쪽을 연결하여 고무의 압축 인장 비틀림 등의 작용에 따라 진동과 소음을 흡수하도록 되어 있으며, 차종에 따라서 진동쪽에 추(댐퍼)를 추가하여 진동쪽의 진폭을 작게 하거나 진동수를 변화시켜 공진을 방지하는 것과 충격을 완화하는 버퍼로드(buffer rod)를 설치한 것 등이 있으나 최근에는 마운트 고무외에 마운트액을 봉입한 액체봉입 마운팅장치가 많이 사용되고 있다.In general, the engine mounting device connects the engine side to the body body via a buffer such as rubber to absorb vibration and noise according to the action of compression tension torsion of the rubber, and according to the model, a weight (damper) is applied to the vibration side. In addition to this, the vibration amplitude is reduced or the frequency is changed to prevent resonance and buffer rods are provided to alleviate the impact. It is used a lot.

도 5와 6에 종래의 엔진지지용 액체봉입 마운팅장치를 도시하였다.5 and 6 illustrate a conventional liquid support mounting apparatus for engine support.

동상 장치는 내측파이프(1)와 외측파이프(2) 사이에 주고무살(4)(4a), 스토퍼(5), 다이어프램(6), 오리피스 구조물(9) 등이 위치하고 있고, 액체가 봉입되어 있는 주액실(10)과 부액실(13)은 오리피스(12)를 통해 봉입액체가 이동하도록 연통되어 있다.The in-phase device is provided between the inner pipe (1) and the outer pipe (2) with a high axle (4) (4a), a stopper (5), a diaphragm (6), an orifice structure (9), and the like. The injection liquid chamber 10 and the liquid injection chamber 13 communicate with each other so that the encapsulation liquid moves through the orifice 12.

이와같은 종래의 마운팅장치는 주액실(10)이 중앙에 솟아있는 스토퍼(5)에 의해 양분되고, 양분된 주액실(10)은 스토퍼(5) 상단과 외측파이프(2, 부호 8은 중간파이프) 사이에 형성된 공간(S) 및 스토퍼(5) 외주에 형성된 공간을 통해 연통하고 있어 엔진을 지지하는 외측파이프(2)가 진동이나 충격력을 받게되면(화살표 방향으로 F작용) 주액실(10)내의 액체가 오리피스(12)를 통해 부액실(13)(14)로 이동하게 되며, 이때 다이어프램(6)이 확장되어 액체를 수용하면서 충격을 흡수하게 된다.In the conventional mounting apparatus, the injection chamber 10 is bisected by the stopper 5, which is formed at the center thereof, and the divided injection chamber 10 is the top of the stopper 5 and the outer pipe 2, and 8 is an intermediate pipe. When the outer pipe (2) supporting the engine is subjected to vibration or impact force (F action in the direction of the arrow), it is communicated through the space (S) formed between the space (S) and the stopper (5) outer periphery. The liquid inside moves through the orifice 12 to the sub-liquid chambers 13 and 14, where the diaphragm 6 expands to absorb the shock while receiving the liquid.

그러나 상기한 종래기술에 의하면 변위량이 큰 힘이 작용할 때 스토퍼(5)의 상부인 접촉면고무살(5b)이 외측파이프(2)의 내면(7)에 접촉하면서 정스프링 상수가 급격히 변화하여 충격력이 발생하고, 접촉면 고무살(5b)의 반복 접촉에 따른 조기 파손문제가 지적되고 있다.However, according to the above-mentioned conventional technology, when the force of displacement is large, the contact surface rubber 5b, which is the upper portion of the stopper 5, contacts the inner surface 7 of the outer pipe 2, and the positive spring constant changes rapidly, so that the impact force is increased. And a problem of premature failure due to repeated contact of the contact surface rubber bars 5b.

이에 본 고안은 상기한 문제점을 감안하여 제안한 것으로서 그의 목적으로 하는 것은 대변위 입력시 특성변화를 부드럽게 하여 충격발생을 줄이고, 변위 억제기능에 따른 내구성능 증대를 도모한 엔진지지용 액체봉입 마운팅장치를 제공하는데 있다.Therefore, the present invention has been proposed in view of the above problems, and its purpose is to reduce the occurrence of impact by smoothing the characteristic change during large displacement input, and to support the liquid-filled mounting device for engine support which aims to increase durability by displacement suppression function. To provide.

본 고안은 상기한 목적을 달성하기 위하여The present invention to achieve the above object

내측파이프와 외측파이프, 내외측파이프 사이에 위치하는 주고무살, 스토퍼 및 다이어프램으로 이루어지는 고무완충재, 고무완충재와 외측파이프 사이에 상하로 형성되며, 오리피스 구조물에 의해 형성된 오리피스 통로를 통해 봉입액체가 상호 이동하는 주액실과 부액실을 포함하는 엔진지지용 액체봉입 마운팅장치에 있어서,A rubber buffer formed of a high axle, a stopper and a diaphragm positioned between the inner pipe and the outer pipe, and the inner and outer pipes, and is formed up and down between the rubber buffer and the outer pipe, and the encapsulated liquid moves through the orifice passage formed by the orifice structure. In the liquid support mounting device for engine support comprising a liquid injection chamber and a liquid injection chamber,

상기 주액실에 돌출하는 스토퍼에는 주액실에 연통하도록 상부측이 개방된 요홈공간이 형성되어 있는 것을 특징으로 한다.The stopper protruding from the pouring chamber is characterized in that a recessed space is formed in which the upper side is opened to communicate with the pouring chamber.

이와같은 구성의 본 고안에 의하면 외측파이프가 힘을 받아 변위를 일으켜 스토퍼의 상단 고무살이 외측파이프 내면에 접촉시에는 요홈공간내가 밀폐되면서, 내부에 밀봉된 액체가 압축작용을 일으키면서 충격력을 완충하게 되며, 그 액체의 압축력이 고무살에 작용하는 압축응력의 부담을 분산시키게 되는 것이다.According to the present invention of such a configuration, the outer pipe is forced to cause displacement, and when the upper rubber bar of the stopper contacts the inner surface of the stopper, the inside of the recess space is sealed, and the liquid sealed therein compresses the impact force. The compressive force of the liquid disperses the burden of the compressive stress acting on the rubber skin.

이하에 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.

도 1은 본 고안에 의한 액체봉입 마운팅장치의 일실시예를 나타내는 측단면도이며 도 2는 동상 실시예의 A-A 단면도로서 종래와 동일 유사한 구성들은 동일부호를 붙여 설명하였다.1 is a side cross-sectional view showing an embodiment of a liquid-encapsulated mounting apparatus according to the present invention, Figure 2 is a cross-sectional view of the A-A of the in-phase embodiment similar to the conventional configuration with the same reference numerals.

도면중 부호 1은 프레임 또는 바디에 지지되는 내측파이프이며 부호 2는 엔진을 지지하는 외측파이프이다.In the figure, reference numeral 1 denotes an inner pipe supported by the frame or body, and reference numeral 2 denotes an outer pipe supporting the engine.

내·외측파이프(1)(2) 사이에는 고무완충재(3)가 들어있으며, 고무완충재(3)는 주고무살(4)(4a), 스토퍼(5), 다이어프램(6)으로 이루어지며, 주고무살(4)(4a)은 외측파이프(2)의 내면(7) 및 도시된 것과같이 외측파이프(2)의 내면(7)에 끼워진 중간파이프(8)의 내면에 접착되어 있으며, 일측 주고무살(4a)에는 호형상이며, 단면이 ㄷ자 또는 ㅌ자인 오리피스 구조물(9)이 형성되어 있다.Between the inner and outer pipes (1) and (2), a rubber buffer (3) is contained, and the rubber buffer (3) is made of apricot flesh (4) (4a), a stopper (5), and a diaphragm (6). The fleshless 4 and 4a are bonded to the inner surface 7 of the outer pipe 2 and to the inner surface of the intermediate pipe 8 fitted to the inner surface 7 of the outer pipe 2 as shown, and to one side An orifice structure 9 having an arc shape and a cross section having a U or U is formed in (4a).

상기 스토퍼(5)는 주고무살(4)(4a)과 외측파이프(2) 사이에 형성되는 주액실(10)의 중앙 상부로 돌출하여 있고, 그의 상단에는 상부측이 개방된 요홈공간(11)이 형성되어 있으며, 상단의 요홈공간(11) 주연부인 접촉면 고무살(5a)이 외측파이프(2)의 내면(7)과 간극(S)을 두고 떨어져 있다.The stopper 5 protrudes to the center upper portion of the liquid injection chamber 10 formed between the high amur (4) (4a) and the outer pipe (2), the upper end of the groove space (11) Is formed, and the contact surface rubber skin 5a which is the periphery of the recess space 11 of the upper end is spaced apart from the inner surface 7 of the outer pipe 2 with the gap S.

상기 주액실(10)은 오리피스 구조물(9)에 의해 형성된 좁은 통로인 오리피스 통로(12)를 통하여 하부의 부액실(13)(14)과 연통하며, 좌우대칭으로 위치하는 2개의 부액실(13)(14)은 연통로(15)를 통하여 액체가 이동하도록 연결되어 있다.The injection chamber 10 communicates with the lower side liquid chambers 13 and 14 through an orifice passage 12, which is a narrow passage formed by the orifice structure 9, and two side liquid chambers 13 which are located in a symmetrical direction. 14 is connected to the liquid to move through the communication path (15).

그리고 얇은 다이어프램(6)에 의해 주고무살(4)(4a)과의 사이에 형성되는 공간(16)은 대기에 개방되어 있다.The space 16 formed by the thin diaphragm 6 with the thin aerosols 4 and 4a is open to the atmosphere.

도 3은 본 고안의 변형된 실시예로서 스토퍼(5)의 상단 주연부가 도 1 실시예의 경우 평활면(평면 또는 호형평면)인 반면 파형면(17)으로 형성되어 있으며, 파형에 의해 요홈공간(11)과 주액실(10)이 복수개의 소통로(18)로 연통하여 상호 액체의 이동교류에 의해 압축분산작용을 하므로 외측파이프(2)와의 간격은 도 1 실시예의 경우보다 작게 설정할 수 있다.3 is a modified embodiment of the present invention, the upper periphery of the stopper (5) is a smooth surface (flat or arc plane) in the case of the first embodiment is formed with a wave surface 17, the recessed space ( 11) and the injection chamber 10 communicates with the plurality of communication paths 18 to perform the compression and dispersing action by the mutual movement of the liquid, so that the interval with the outer pipe (2) can be set smaller than in the case of FIG.

이와같은 구성의 본 고안은 외측파이프(2)에 화살표 F의 힘이 작용하게 되면 외측파이프(2)의 처짐이 발생하게 되며, 이 처짐은 1차로 주고무살(4)(4a)에 의해 완충되지만, 주액실(10)내의 액체가 압축력을 받아 오리피스 통로(12)를 통해 부액실(13)(14)로 액체를 방출하므로써 변위를 흡수하게 된다.According to the present invention, the deflection of the outer pipe 2 occurs when the force of the arrow F acts on the outer pipe 2, and this deflection is primarily buffered by the agitation (4) (4a). The liquid in the injection chamber 10 receives the compressive force to absorb the displacement by discharging the liquid into the sub-liquid chambers 13 and 14 through the orifice passage 12.

이때, 부액실(13)(14)을 형성하는 다이어프램(6)이 대기에 개방된 공간(16)측으로 확장하여 부풀게 되면서 주액실(4)내의 액체가 이동하게 되는 것이다.At this time, as the diaphragm 6 forming the sub liquid chambers 13 and 14 expands and expands toward the space 16 open to the atmosphere, the liquid in the liquid injection chamber 4 moves.

그러나 이때 외측파이프(2)의 변위량이 커서 스토퍼(5)의 상부 접촉면고무살(5a)이 외측파이프(2) 내면(7)에 닿게되면, 그 순간부터 요홈공간(11)내의 액체가 압축작용에 의해 저항하여 변위를 줄이게 되므로 도 4에 도시하는 것과같이 변곡점 이후의 변위량을 완만하게 변화시켜 급격한 변위량 변화에 따른 충격을 방지하게 된다.However, at this time, when the displacement amount of the outer pipe 2 is so large that the upper contact surface rubber 5a of the stopper 5 contacts the inner surface 7 of the outer pipe 2, the liquid in the recessed space 11 is compressed from that moment. Since the resistance is reduced to reduce the displacement, as shown in FIG. 4, the displacement after the inflection point is gently changed to prevent the impact caused by the sudden displacement.

그리고 접촉면고무살(5a)을 파형으로 형성한 경우 소통로(18)를 통해 압축되는 요홈공간(11)내의 액체가 압축력 증대에 따라 소량씩 주액실(10)로 방출되고, 그 주액실(10)내의 액체는 다시 오리피스 통로(12)를 통해 부액실(13)(14) 측으로 이동하게 되므로 완충 효과를 높일 수 있게 되는 것이다.And when the contact surface rubber (5a) is formed in a wave form, the liquid in the groove space 11 is compressed through the communication path 18 is discharged into the injection chamber 10 in small amounts as the compression force increases, the injection chamber 10 The liquid in the) is moved back to the sub-liquid chambers 13 and 14 through the orifice passage 12 to increase the buffering effect.

이상과 같은 본 고안에 의하면 주고무살로부터 주액실측에 돌출되어 있는 스토퍼의 상부에 주액실에 연통하는 요홈공간을 마련하는 것에 의해서 스토퍼와 외측파이프 사이에 형성되어 있는 간극을 넘어서는 대변위가 발생하는 경우 요홈공간내의 액체가 압축되면서 변위량의 변화특성을 완만하게 하여 충격력을 감소시키게 되는 효과가 있으며, 요홈공간내에서 압축되는 봉입액체가 고무살의 압축응력 부담을 분산시키게 되어 내구성을 향상시키는 효과가 있다.According to the present invention as described above, when a large displacement exceeding the gap formed between the stopper and the outer pipe occurs by providing a recessed space communicating with the injection chamber in the upper part of the stopper protruding from the mussels, the injection chamber side. As the liquid in the groove space is compressed, the change of the displacement amount is smoothed, thereby reducing the impact force, and the encapsulated liquid compressed in the groove space distributes the compressive stress load of the rubber skin, thereby improving durability.
