Description
본 발명은 엔진마운팅멤버의 충격흡수 구조에 관한 것으로서, 특히 엔진마운팅멤버의 전후 양측부에 완충보강부재를 설치하여 엔진마운팅멤버의 강성을 증대시키므로 차량 정면 충돌시 가해지는 충격을 탄력적으로 흡수할 수 있는 차량용 엔진마운팅멤버의 충격흡수 구조에 관한 것이다.The present invention relates to a shock absorbing structure of an engine mounting member, and in particular, by installing a buffer reinforcing member at both front and rear sides of the engine mounting member to increase the rigidity of the engine mounting member, it is possible to elastically absorb the impact applied to the frontal collision of the vehicle. The present invention relates to a shock absorbing structure of an engine mounting member for a vehicle.
일반적으로 차량용 엔진마운팅멤버는 엔진마운팅이 설치되어 차량의 엔진을 지지하면서 엔진에서 발생되는 진동이나 소음을 상기 엔진마운팅을 통해 흡수하게 되어 차량의 정숙성과 승차감을 향상시키는 기능을 하게 된다.In general, the engine mounting member for the vehicle is installed to support the engine of the vehicle while the engine mounting is installed to absorb the vibration or noise generated from the engine through the engine mounting to improve the quietness and ride comfort of the vehicle.
즉, 상기 엔진마운팅은 엔진을 지지하는 기능외에도 차량충돌시 엔진에 가해지는 충격을 흡수하여 엔진이 후방으로 밀리는 현상을 방지하게 되는 것이다.That is, the engine mounting absorbs the shock applied to the engine in the event of a vehicle crash in addition to the function of supporting the engine, thereby preventing the engine from being pushed backward.
이러한 차량용 엔진마운팅멤버(1)의 구조는 도 4에서 보는 바와 같이 양측단부에는 차체의 크로스멤버(C)와 연결설치되고, 중앙 양측부에는 엔진마운팅(M)이 고정 설치되며, 전후부에는 차량 정면 충돌시 강성을 증대시키기 위해 보강파이프(P)가 고정 설치된다.As shown in FIG. 4, the structure of the engine mounting member 1 for the vehicle is connected to the cross member C of the vehicle body at both end portions, and the engine mounting M is fixedly installed at both sides of the center, and the vehicle at the front and rear portions thereof. Reinforcement pipe (P) is fixedly installed to increase the rigidity in frontal collision.
따라서, 상기 엔진마운팅멤버(1)는 차체의 크로스멤버(C)에 고정설치된 상태에서 이 엔진마운팅멤버(1)의 전후 양측에 설치된 보강파이프(P)에 의해 엔진(E)을 지지하도록 되어 있으므로 정면충돌 등과 같은 충돌사고로 인해 엔진(E)이나 엔진마운팅멤버(1)에 충격이 가해지는 경우, 이 엔진마운팅멤버(1)는 전후 양측부에 설치된 보강파이프(P)에 의해 충격을 흡수하게 되어 있으나, 이 엔진마운팅멤버(1)에 설치된 보강파이프(P)는 단순히 엔진마운팅멤버(1)의 강성을 증대시킨 것에 불과하므로 전방 충돌 사고로 인해 가해지는 충격을 신축적으로 흡수하지 못하고 쉽게 변형되어 왔었다.Therefore, since the engine mounting member 1 is fixed to the cross member C of the vehicle body, the engine mounting member 1 is supported by the reinforcement pipes P installed on both front and rear sides of the engine mounting member 1. When an impact is applied to the engine E or the engine mounting member 1 due to a collision accident such as a frontal collision, the engine mounting member 1 is adapted to absorb the impact by the reinforcement pipes P installed at both front and rear sides. However, since the reinforcement pipe P installed in the engine mounting member 1 merely increases the rigidity of the engine mounting member 1, it does not elastically absorb the impacts caused by the front collision accident and is easily deformed. It has been.
따라서, 이와 같은 종래의 차량용 엔진마운팅멤버의 구조는 전후 양측부에 보강파이프가 설치되어 엔진을 견고하게 지지하면서 차량의 정면 충돌시 충격을 흡수토록 되어 있으나, 차량 충돌시 전방으로 부터 가해지는 충격을 신축적으로 흡수하지 못하므로 엔진이 운전석측으로 쉽게 밀리는 현상이 발생되는 등 충돌 사고시 차량의 안전성을 저해하는 문제점이 발생되었다.Therefore, the conventional structure of the engine mounting member for a vehicle is provided with reinforcement pipes installed at both front and rear sides so as to firmly support the engine and to absorb shock during frontal collision of the vehicle. Since it is not absorbed elastically, the engine is easily pushed toward the driver's seat, causing a problem of impairing the safety of the vehicle in a crash accident.
이에 본 발명에서는 엔진마운팅멤버의 전후 양측부에 유체의 이동에 의해 탄력적으로 충격을 흡수하는 완충보강부재를 설치하여 엔진마운팅멤버의 강성을 증대시키면서 차량 정면 충돌시 가해지는 충격을 보다 효과적으로 흡수할 수 있도록 한 것을 목적으로 한다.Accordingly, in the present invention, by installing a buffer reinforcing member to elastically absorb the shock due to the movement of the fluid in the front and rear sides of the engine mounting member to increase the stiffness of the engine mounting member can more effectively absorb the impact applied in front of the vehicle collision. The purpose is to make it.

In the vehicle engine mounting member, characterized in that the buffer reinforcing member 20 is installed in the center of the engine mounting member (10).
이하, 본 발명의 실시예를 첨부된 예시도면을 통해 보다 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.
도 2는 본 발명의 구조를 나타낸 단면도이고, 도 3은 본 발명의 작용상태를 나타낸 도 2의 A부 확대단면도이다.Figure 2 is a cross-sectional view showing the structure of the present invention, Figure 3 is an enlarged cross-sectional view A portion of Figure 2 showing an operating state of the present invention.
도시된 바와 같이 차체의 크로스멤버(C)에 설치되며 엔진마운팅(M)이 설치되는 엔진마운팅멤버(10)는 전후부에 이 엔진마운팅멤버(10)의 강성을 증대시키는 완충보강부재(20)를 설치하며, 이 완충보강부재(20)는 엔진마운팅멤버(10)의 중앙부 양측으로 분리된 제1,2파이프(30)(40)를 용접 등으로 각각 고정 설치하고, 이 제1,2파이프(30)(40)의 내부에는 유체파이프(50)를 삽입 설치하여 이 유체파이프(50)에 상기 제1,2파이프(30)(40)를 용접 등으로 고정 설치하므로 상기 제1,2파이프(30)(40)가 유체파이프(50)에 의해 연결되도록 하며, 상기 유체파이프(50)의 내부에는 오리피스(52)가 형성한다.As shown, the engine mounting member 10 installed on the cross member C of the vehicle body and the engine mounting M is installed is a buffer reinforcing member 20 which increases the rigidity of the engine mounting member 10 in front and rear. The buffer reinforcing member 20 is fixed to the first and second pipes 30 and 40 separated by both sides of the central portion of the engine mounting member 10 by welding, respectively, and the first and second pipes. The first and second pipes 30 and 40 are fixed to the fluid pipe 50 by welding and the like, by inserting and installing the fluid pipe 50 in the interior of the 30 and 40 pipes. 30 and 40 are connected to each other by the fluid pipe 50, and an orifice 52 is formed inside the fluid pipe 50.
이와 같이 구성된 본 발명의 작용 및 효과를 상세하게 설명하면 다음과 같다.Referring to the operation and effect of the present invention configured as described in detail as follows.
도 2에서와 같이 완충보강부재(20)가 설치된 엔진마운팅멤버(10)는 중앙 양측부에 설치된 엔진마운팅(M)에 의해 전달되는 엔진(E)의 하중을 견고하게 지지하게 되며, 차량의 정면충돌과 같은 사고로 인해 상기 엔진마운팅멤버(10)에 충격이 가해지는 경우에는 유체파이프(50)에 의해 연결된 제1,2파이프(30)(40)가 상기 엔진마운팅멤버(10)에 설치되어 있으므로 전방측으로 부터 가해지는 충격을 신축적으로 흡수하게 된다.As shown in FIG. 2, the engine mounting member 10 provided with the buffer reinforcing member 20 firmly supports the load of the engine E transmitted by the engine mounting M installed at both sides of the center, and the front of the vehicle. When an impact is applied to the engine mounting member 10 due to an accident such as a collision, the first and second pipes 30 and 40 connected by the fluid pipe 50 are installed in the engine mounting member 10. Therefore, the impact from the front side is elastically absorbed.
즉, 상기 완충보강부재(20)는 유체파이프(50)에 의해 연결된 제1,2파이프(30)(40)가 설치되어 있으므로 엔진마운팅멤버(10)의 강성을 증대시키게 되며, 더욱이 이 제1,2파이프(30)(40)는 유체파이프(50)에 의해 2중구조로 구비되므로 보다 증대된 강성을 지니게 되며, 차량의 강한 정면 충돌사고로 인해 충격이 가해져 상기 유체파이프(50)가 변형되는 경우, 상기 유체파이프(50)는 도 3에서와 같이 내부에 오리피스(52)가 형성되어 있으므로 이 오리피스(52)를 통해 유체가 유체파이프(50)내에서 좌우로 이동되어 상기 유체파이프(50)에 가해지는 충격을 탄력적으로 흡수하게 되므로 차량의 전면 충돌시에도 엔진(E)을 견고하게 지지하게 되는 것이다.That is, since the buffer reinforcing member 20 is provided with the first and second pipes 30 and 40 connected by the fluid pipe 50, the rigidity of the engine mounting member 10 is increased. Since the two pipes 30 and 40 are provided in a double structure by the fluid pipe 50, the two pipes 30 and 40 have increased rigidity, and the fluid pipe 50 is deformed due to an impact due to a strong frontal collision of the vehicle. In this case, the fluid pipe 50 has an orifice 52 formed therein as shown in FIG. 3, so that the fluid is moved from side to side within the fluid pipe 50 through the orifice 52 so that the fluid pipe 50 is formed. Since the shock applied to the elastically absorbed to the front of the vehicle will be firmly supported the engine (E).
이상에서와 같이 본 발명은 엔진마운팅멤버의 전후 양측부에 완충보강부재를 설치하여 엔진마운팅멤버의 강성을 증대시키므로 차량 정면 충돌시 가해지는 충격을 오리피스를 통한 유체의 이동에 의해 탄력적으로 흡수하여 엔진마운팅멤버의 변형을 최소화하면서 엔진을 보다 견고하게 지지하는 등 엔진마운팅멤버의 강성을 가일층 증대시킨 매우 유용한 효과가 있는 것이다.As described above, the present invention increases the rigidity of the engine mounting member by installing buffer reinforcing members at both front and rear sides of the engine mounting member, so that the impact applied during the frontal collision of the vehicle is elastically absorbed by the fluid movement through the orifice. There is a very useful effect that further increases the rigidity of the engine mounting member, such as supporting the engine more firmly while minimizing the deformation of the mounting member.
