Description

차량의 바디마운트{Body-Mount in Vehicle}Body-Mount in Vehicle

본 발명은 차량의 바디마운트에 관한 것으로, 차량의 바디와 프레임을 연결하는 바디마운트에 있어서, 어퍼러버가 횡방향으로 충분히 지지되도록 하여 횡방향 하중에 대한 완충작용을 충분히 수행되도록 하는 차량 바디마운트에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body mount of a vehicle, wherein the body mount connecting the body and the frame of the vehicle includes: a vehicle body mount that sufficiently supports the upper rubber in the lateral direction to sufficiently cushion the transverse load; It is about.

일반적으로 차량의 구성부분은 바디와 새시로 구분되며, 바디는 차실과 적재함 등으로 이루어져 사람이나 화물을 싣는 차량의 외장에 상당하는 부분이다.In general, the components of the vehicle are divided into a body and a chassis, the body is composed of a car compartment and a loading box, etc., which corresponds to the exterior of a vehicle carrying a person or cargo.

새시는 차량에서 바디부분을 제외한 것으로, 차량의 골격에 해당되는 프레임을 위시하여 이 프레임에 엔진 등 주행에 필요한 일체의 장치가 장착되어진 것을 의미한다.The chassis excluding the body part from the vehicle, which means that any frame necessary for driving such as an engine is mounted on the frame corresponding to the frame of the vehicle.

프레임은 바디에서 전달되는 하중, 전후 차축에서의 반력을 지지하는 중요 부분으로서, 차량 주행중 노면으로부터의 충격이나 하중 등에 의해 생기는 굽힘, 비틀림, 텐션, 진동 등에 충분히 견딜 수 있는 강도와 강성을 가짐과 동시에 경량일 것이 요구된다.The frame is an important part that supports the load transmitted from the body and the reaction force on the front and rear axles, and has the strength and rigidity that can sufficiently withstand bending, torsion, tension, and vibration caused by impact or load from the road surface while driving. It is required to be lightweight.

한편, 상용차 등에 있어서는 프레임과 바디가 구분되어 있는 관계로 프레임과 바디의 연결에 있어, 노면으로부터 프레임에 전달된 진동 및 소음의 바디전달을 차단하고 두 강체의 직접체결에 의한 문제점을 방지하기 위해 결합매개체로서 완충재인 바디마운팅이 장착된다.On the other hand, in a commercial vehicle, the frame and the body are separated, so that the frame and the body are connected to each other to block the transmission of vibration and noise transmitted from the road surface to the frame and to prevent problems caused by the direct connection between the two bodies. As a medium, a body mounting which is a cushioning material is mounted.

예시도면 도 1 은 차량 프레임에 설치되는 종래의 바디마운트를 나타낸 설명도로서, 다점지지를 위해 프레임(1)의 양측 사이드멤버를 따라 프레임(1)에 포함되는 브라켓이 마련되어 있으며, 이 브라켓에 마운팅러버(3)와 함께 바디(4)와 프레임(2)이 마운트보울트(5)로 체결된다.Exemplary Drawings FIG. 1 is an explanatory diagram showing a conventional body mount installed on a vehicle frame. A bracket included in the frame 1 is provided along side sides of the frame 1 for multi-point support, and is mounted on the bracket. The body 4 and the frame 2 together with the rubber 3 are fastened to the mount bolt 5.

한편, 마운팅러버(3)는 2개로 구분되어 어퍼러버(7)는 바디저면과 프레임 사이에 장착되고, 로어러버(8)는 상기 프레임 저부에 장착되어 있으며, 로어러버(8)의 저부에 돌출된 마운팅보울트(5)에 너트(6)가 체결되어져 로어러버(8)와 함께 어퍼러버(7)가 체결되어 있다.On the other hand, the mounting rubber (3) is divided into two, the upper rubber (7) is mounted between the body bottom and the frame, the lower rubber (8) is mounted on the bottom of the frame, protrudes to the bottom of the lower rubber (8) The nut 6 is fastened to the mounting bolt 5, and the upper rubber 7 is fastened together with the lower rubber 8.

또한, 마운팅러버(3)의 중앙에는 스페이서(2)가 장착되어 있으며, 마운팅러버(3)의 양단, 즉 어퍼러버(7)의 상단과 로어러버(8)의 하단에는 지지플레이트(9)(10)가 장착되어 있다.In addition, a spacer 2 is mounted at the center of the mounting rubber 3, and at both ends of the mounting rubber 3, that is, at the upper end of the upper rubber 7 and at the lower end of the lower rubber 8, a support plate 9 ( 10) is installed.

그러나, 이러한 종래의 바디마운트는 바디 상하배치로의 특성상 횡강성에 취약하다는 문제점이 있다.However, such a conventional body mount has a problem in that it is vulnerable to lateral stiffness due to the characteristics of the body up and down arrangement.

즉, 마운팅러버(3)의 상하로는 바디(4)와 프레임(1)으로 지지되어 탄성재질의 완충이 충분히 수행하고 있지만, 마운팅러버의 좌우평면방향인 횡방으로는 마운팅러버(3)를 충분히 지지할 부재가 미비하여 완충작용을 충분히 수행하지 못하였던 것이어서 바디마운트의 횡강성이 취약하였으며, 특히 바디(4)와 프레임(1)사이에 위치되는 어퍼러버(7)의 횡강성 보완이 필요한 것이다.That is, the upper and lower parts of the mounting rubber 3 are supported by the body 4 and the frame 1 to sufficiently cushion the elastic material. However, the mounting rubber 3 is sufficiently provided in the horizontal direction in the horizontal direction of the mounting rubber. Since the member to be supported was insufficient to perform the buffering function sufficiently, the lateral rigidity of the body mount was weak, and in particular, the lateral stiffness of the upper rubber 7 located between the body 4 and the frame 1 was required. .

이에 본 발명은 상기 문제점을 개선하기 위하여 안출된 것으로, 바디마운트의 어퍼러버가 횡방향으로 충분히 지지되도록 하여 횡방향 하중에 대한 완충작용을 충분히 수행되도록 하는 차량 바디마운트를 제공함에 그 목적이 있는 것이다.Accordingly, the present invention has been made in order to improve the above problems, and the object of the present invention is to provide a vehicle body mount so that the upper rubber of the body mount is sufficiently supported in the lateral direction to sufficiently perform the buffering action against the lateral load. .

이를 위한 본 발명은 어퍼러버가 하중에 의해 변형되는 부재임에 따라 부분적으로 어퍼러버의 측부를 지지하는 지지체를 다중으로 마련한 것으로, 지지플레이트에 연장된 홈부인 제1지지체는 어퍼러버의 상부를 지지하고, 프레임에 성형된 홈부인 제2지지체는 어퍼러버의 하부를 지지하며, 제3지지체는 마운트보울트의 체결을 위한 관통공에 형성된 홈부로 어퍼러버의 중앙하부가 프레임에 끼워지도록 하여 제2지지체와 더불어 서포트캡으로서 어퍼러버의 하부를 지지한 것이다.According to the present invention, as the upper rubber is a member deformed by a load, a plurality of supports are partially provided to support the side portions of the upper rubber, and the first support body, which is a groove extended to the support plate, supports the upper portion of the upper rubber. The second support, which is a groove formed in the frame, supports the lower portion of the upper rubber, and the third support is a groove formed in the through hole for fastening the mount bolt so that the lower center of the upper rubber fits into the frame. In addition, it supports the lower part of the upper rubber as a support cap.

In addition, the lower outer peripheral portion of the upper rubber 9 is formed in the second support body 14 into which the lower portion of the upper rubber 7 is fitted, and the inner peripheral portion of the frame through hole through which the mount bolt 5 penetrates. It is a body mount of a vehicle in which a third support 16 is formed which extends toward the upper side of the lower rubber and fits the lower center portion of the upper rubber 7.

상술된 바와 같이 본 발명은 마운팅러버(3), 특히 바디(4)와 프레임(1) 사이에 직결된 어퍼러버(7)의 횡방향으로 탄성체를 지지하는 지지수단을 제공한다.As described above, the present invention provides support means for supporting the elastic body in the transverse direction of the mounting rubber 3, in particular the upper rubber 7 directly connected between the body 4 and the frame 1.

이를 위한 본 발명은 어퍼러버(7)가 하중에 의해 변형되는 부재임에 따라 부분적으로 어퍼러버(7)의 측부를 지지하는 지지체를 다중으로 마련한 것으로, 제1지지체(12)는 어퍼러버(7)의 상부를 지지하고, 제2지지체(14)는 어퍼러버(7)의 하부를 지지하며, 제3지지체(16)는 어퍼러버(7)의 중앙하부가 프레임에 끼워지도록 하여 제2지지체(14)와 더불어 서포트캡으로서 어퍼러버(7)의 하부를 지지한 것이다.To this end, according to the present invention, since the upper rubber 7 is a member that is deformed by a load, the support body partially supports the side of the upper rubber 7, and the first support 12 includes the upper rubber 7. ) And the second support 14 supports the lower portion of the upper rubber 7, and the third support 16 allows the lower center of the upper rubber 7 to fit into the frame. 14) In addition to supporting the lower portion of the upper rubber (7) as a support cap.

상기 제1지지체(12)는 지지플레이트(9)가 하부로 연장되어 어퍼러버(7)의 상부가 끼워지는 홈부를 제공한다.The first support 12 provides a groove portion into which the support plate 9 extends downward so that the upper portion of the upper rubber 7 is fitted.

이러한 홈부에 의해 지지플레이트(9)가 어퍼러버(7)의 상부에서 횡방향 하중에 대한 지지역할을 하게 된다.This groove causes the support plate 9 to support the lateral load at the top of the upper rubber 7.

이와 대비되어 상기 제2지지체(14)는 어퍼러버(7)의 하부에서 횡방향 하중에 대한 지지역할을 하는 것으로, 어퍼러버(7)가 위치되는 프레임(1)에 어퍼러버가 끼워지는 홈부가 성형된 것이다.In contrast, the second support 14 serves to support the lateral load at the lower portion of the upper rubber 7, and the groove portion into which the upper rubber is fitted to the frame 1 in which the upper rubber 7 is located. It is molded.

물론, 종래에도 프레임(1)에 어퍼러버(7)가 안착되기 위한 홈부가 형성되어 있었지만, 이것과 본 발명에 따른 제2지지체와는 다르다.Of course, the groove 1 for seating the upper rubber 7 in the frame 1 is conventionally formed, but this is different from the second support body according to the present invention.

즉, 종래의 홈부는 단순히 어퍼러버(7)의 장착위치를 결정해주기 위한 것으로, 어퍼러버(7)의 하단이 단순 거치되는 것에 불과하다.That is, the conventional groove is simply to determine the mounting position of the upper rubber 7, the lower end of the upper rubber 7 is simply mounted.

반면, 본 발명에 따른 제2지지체(14)는 어퍼러버(7)가 끼워지는 것으로, 어퍼러버(7)의 하측외주면을 지지하여 어퍼러버(7) 하부의 횡방향 하중에 대한 지지체를 제공하게 되는 것이다.On the other hand, the second support 14 according to the present invention is the upper rubber (7) is fitted, to support the lower outer peripheral surface of the upper rubber (7) to provide a support for the transverse load of the lower portion of the upper rubber (7) Will be.
