Description
본 고안은 자동차용 베인펌프의 하우징과 리어커버의 실링구조에 관한 것으로서, 더욱 상세하게는 베인펌프의 하우징과 리어커버가 결합하는 면접촉부로 하우징과 리어커버의 접촉면에 일치하도록 동일형상의 수지 시일플레이트를 삽입설치하여 실링을 이루도록 함으로서 하우징과 리어커버가 결합하는 면접촉부의 시일 면적을 확대하여 기밀성을 향상시킴으로서 오일이 누유되는 것을 방지하고 하우징의 접촉면과 수지 시일플레이트가 동일형상으로 결합하므로 찍힘 및 쏠림의 문제로 인한 결함위험을 저감하도록 하는 자동차용 베인펌프의 하우징과 리어커버의 실링구조에 관한 것이다.The present invention relates to a sealing structure of a housing and a rear cover of a vane pump for a vehicle, and more particularly, a surface contact portion where a housing and a rear cover of a vane pump are coupled to each other so as to match the contact surface of the housing and the rear cover. By inserting and installing the plate to achieve sealing, the sealing area of the surface contact portion joining the housing and the rear cover is enlarged to improve airtightness, preventing oil leakage and the contact surface of the housing and the resin seal plate are combined in the same shape. The present invention relates to a sealing structure of a housing and a rear cover of a vane pump for a vehicle to reduce a risk of defects due to a problem of tilting.
일반적으로 종래 자동차용 베인펌프의 하우징과 리어커버의 실링구조는 제3도와 제4도에 도시된 바와 같이 일측면으로 소정깊이를 갖는 요홈(14)이 형성된 베인펌프(10)의 하우징(11)에 면접촉하여 내부로 오일이 흡입되도록 유로가 형성된 리어커버(12)가 결합설치되고 상기 하우징(11)의 요홈(14)에 안착되어 리어커버(12)와 베인펌프(10)의 하우징(11)이 결합되는 접촉면으로 0-링(13)이 삽입설치되어 있다.In general, the sealing structure of the housing and the rear cover of the conventional vehicle vane pump is a housing 11 of the vane pump 10 is formed with a groove 14 having a predetermined depth on one side as shown in FIG. 3 and FIG. A rear cover 12 having a flow path formed therein so as to suck oil into the surface in contact with the surface thereof is coupled to the housing 11 of the rear cover 12 and the vane pump 10 by being seated in the recess 14 of the housing 11. The 0-ring (13) is inserted into the contact surface to which is connected.
따라서 종래에는 베인펌프(10)의 하우징(11)과 리어커버(12)가 결합되는 하우징(11)의 요홈(14)에 0-링(13)을 안착시키고 0-링(13)이 안착된 하우징(11)의 일측면으로 리어커버(12)를 결합하여 하우징(11)과 리어커버(12)의 접촉면으로 실링을 이루도록 함으로서 하우징(11)과 리어커버(12)의 접촉면에서 오일의 누유되는 것을 방지하도록 하였다.Therefore, in the related art, the 0-ring 13 is seated in the groove 14 of the housing 11 to which the housing 11 and the rear cover 12 of the vane pump 10 are coupled, and the 0-ring 13 is seated. Oil is leaked from the contact surface between the housing 11 and the rear cover 12 by coupling the rear cover 12 to one side of the housing 11 to form a seal with the contact surface between the housing 11 and the rear cover 12. To prevent them.
그러나 이와 같은 종래의 실링구조는 베인펌프 하우징의 요홈에 삽입게재되는 0-링의 형상이 불규칙하여 하우징과 리어커버의 조립시 형상변형에 의한 씹힘현상과 베인펌프 내부 부분품과의 찍힘 위험성 및 쏠림등으로 인한 결함위험이 있으며 하우징의 일측면으로 0-링이 안착되는 요홈의 형상이 불규칙하여 조도 및 요홈의 깊이 관리가 어려워 기밀성이 떨어져 오일이 누유되는 문제점들이 있었다.However, such a conventional sealing structure is irregular in the shape of the 0-ring inserted into the groove of the vane pump housing, so that the chewing phenomenon due to the shape deformation during assembly of the housing and the rear cover and the risk of being caught by the internal parts of the vane pump, etc. There is a risk of defects due to the irregular shape of the groove in which the 0-ring is seated on one side of the housing is difficult to control the roughness and depth of the groove, there is a problem that the oil is leaked due to airtightness.
본 고안은 이와 같은 문제점들을 개선하기 위하여 안출한 것으로서, 본 고안의 목적은 베인펌프의 하우징과 리어커버가 결합하는 면접촉부로 0-링 대신에 접촉면에 일치하도록 동일형상의 수지 시일플레이트를 삽입설치하여 실링을 이루도록 함으로서 하우징과 리어커버가 결합하는 면접촉부의 시일 면적을 확대하여 기밀성을 향상시킴으로서 오일이 누유되는 것을 방지하고 하우징의 접촉면과 수지 시일플레이트가 동일형상으로 결합하므로 찍힘 및 쏠림의 문제로 인한 결함위험을 저감하도록 하는 자동차용 베인펌프의 하우징과 리어커버의 실링구조를 제공하는데 있다.The present invention has been devised to solve these problems, and an object of the present invention is to install a resin seal plate of the same shape so as to match the contact surface instead of the 0-ring as a surface contact portion where the housing and the rear cover of the vane pump are coupled. By forming the seal to improve the airtightness by increasing the sealing area of the surface contact portion to which the housing and the rear cover are coupled to prevent oil leakage and because the contact surface of the housing and the resin seal plate is combined in the same shape, the problem of taking and pulling To provide a sealing structure of the housing and the rear cover of the vane pump for automobiles to reduce the risk of defects.

이하, 본 고안을 첨부된 도면에 의하여 그 기술적 구성을 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the technical configuration by the accompanying drawings of the present invention in more detail as follows.
제1도는 본 고안의 결합상태를 보인 단면도이고, 제2도는 제1도의 A-A선 단면도로서, 베인펌프(100)의 하우징(110)과 리어커버(120)가 결합하는 면접촉부로 하우징(110)과 리어커버(120)의 접촉면에 일치하도록 동일형상의 수지 시일플레이트(130)를 삽입설치하여 실링을 이루도록 하는 것을 구성상의 특징으로 한다.1 is a cross-sectional view showing a coupling state of the present invention, 2 is a cross-sectional view taken along the line AA of Figure 1, the housing 110 of the vane pump 100, the surface contact portion to which the rear cover 120 is coupled to the housing 110 The resin seal plate 130 of the same shape is inserted and installed so as to correspond to the contact surface of the rear cover 120 to form a sealing.
또한 상기 수지 시일플레이트(130)는 하우징(110)과 리어커버(120)의 결합을 위한 체결홀(Hole)(132)을 형성하는 것을 특징으로 한다.In addition, the resin seal plate 130 is characterized in that for forming a fastening hole (Hole) 132 for coupling the housing 110 and the rear cover 120.
이와 같이 구성하는 본 고안은 베인펌프(100)의 하우징(110)과 리어커버(120)가 결합하는 면접촉부로 하우징(110)과 리어커버(120)의 면접촉부로 동일한 형상을 이루는 수지 시일플레이트(130)를 삽입설치하는데 이때 수지 시일플레이트(130)는 하우징(110)과 리어커버(120)의 결합을 위하여 하우징(110)과 리어커버(120)의 면접촉부의 체결홀(132)을 형성하고 있어 하우징(110)과 리어커버(120)의 시일면적을 확대하여 기밀성을 향상시킴으로서 오일이 누유되는 것을 방지하고 하우징(110)과 리어커버(120)의 결합시 찍힘 및 쏠림등의 문제로 인한 결함위험을 저감한다.The present invention configured as described above is a resin contact plate forming the same shape as the surface contact portion of the housing 110 and the rear cover 120 as a surface contact portion that the housing 110 and the rear cover 120 of the vane pump 100 are coupled. In this case, the resin seal plate 130 forms a fastening hole 132 of the surface contact portion of the housing 110 and the rear cover 120 to be coupled to the housing 110 and the rear cover 120. The sealing area of the housing 110 and the rear cover 120 is enlarged to improve the airtightness, thereby preventing oil from leaking, and when the housing 110 and the rear cover 120 are coupled, Reduce the risk of defects
이상과 같이 이루어지는 본 고안은 하우징과 리어커버가 결합하는 면접촉부로 면접촉부와 동일한 형상을 이루는 수지 시일플레이트를 삽입설치하여 실링을 이루도록 함으로서 하우징과 리어커버의 결합시 시일 면적을 확대하여 기밀성을 향상시킴으로서 오일이 누유되는 것을 방지하고 하우징의 접촉면과 수지 시일플레이트가 동일형상으로 결합하여 찍힘 및 쏠림의 문제로 인한 결함위험을 저감시키도록 하는 매우 유용한 고안이다.The present invention made as described above improves airtightness by enlarging the seal area when the housing and the rear cover are combined by inserting and installing a resin seal plate having the same shape as the surface contact portion as a surface contact portion where the housing and the rear cover are coupled. It is a very useful design to prevent oil leakage and to reduce the risk of defects due to the problem of nailing and pulling by combining the contact surface of the housing and the resin seal plate in the same shape.
