Description

자동차용 서스펜션 멤버의 마운팅 파이프구조{Mounting pipe structure of car suspension member}Mounting pipe structure of car suspension member

본 발명은 자동차의 서스펜션 멤버를 차체에 연결하는 마운팅 파이프 구조에 관한 것이다.The present invention relates to a mounting pipe structure for connecting a suspension member of an automobile to a vehicle body.

자동차의 서스펜션 멤버는 그 양측에 마운팅 파이프를 적정높이로 돌출형성하여 마운팅 파이프 단부에 갖는 고정공을 통하여 차체와 볼트넛으로 연결고정되는 것으로서, 대표적인 선행기술로서는 일본실개평11-115796호를 예로 들 수가 있다.Suspension members of automobiles are formed by protruding mounting pipes on both sides thereof to an appropriate height, and being connected to the vehicle body and bolt nuts through fixing holes provided at the ends of the mounting pipes. There is a number.

즉 일본실개평11-115796호는 도 3에서와 같이, 마운팅 파이프(50) 단부를 절삭가공하여 상기 절삭면에 결합공을 갖는 좌판(52)을 용접형성하고 상기 좌판 저부에는 파이프 내지는 플랜지 파이프(54)를 용접고정하여서 된 것으로서, 파이프 이외에 별도의 좌판을 필요로 하는데 따른 부품수의 증가로 재료비가 많이 소요되고 용접면이 넓어 작업성이 떨어지고 또 작업공수가 늘어나 제조시간 및 인력이 많이 소요되며 이로 인하여 생산성의 저하를 가져오게 된다.That is, Japanese Patent Application Laid-Open No. 11-115796, as shown in Figure 3, by cutting the end of the mounting pipe 50 to form a weld plate 52 having a coupling hole on the cutting surface, the pipe bottom or flange pipe ( 54) is fixed by welding, it requires a separate seat plate in addition to the pipe, and the increase in the number of parts requires a lot of material cost, the welding surface is wide, the workability is reduced, and the labor time is increased, and the manufacturing time and manpower are increased. This leads to a decrease in productivity.

또한 좌판(52)은 마운팅 파이프(50)의 절삭면에 용접하거나 또는 플랜지 파이프(54)를 좌판(52)에 용접하는 과정에서 플랜지가 기울거나 변형된다.In addition, the seat plate 52 is inclined or deformed in the process of welding the cutting surface of the mounting pipe 50 or the flange pipe 54 to the seat plate 52.

또한 좌판의 용접위치는 마운팅 파이프의 절삭면에 의해 결정되므로 마운팅 파이프의 제조시 약간의 변형으로 미리 주어진 높이를 유지하지 못하게 되면 좌판의 용접과정에서는 치유될 수 없어 결국 좌판과 차체의 평면부 사이에 유격이 발생되어 불량처리될 수 밖에 없고 또 유격을 없애준다 하더라도 좌판의 용접시 용접열에 의한 좌판의 변형으로 수평을 유지하기 어려워 결국 차체의 평면부와 전체적으로 긴밀히 밀착되지 못해 볼트너트를 이용한 체결시 체결강성이 떨어지고, 차량운행시 차체진동으로 볼트가 쉽게 이완될 우려가 있어 안전사고를 야기시키게 되는등 많은 문제점들이 지적되고 있는 것이었다.In addition, the welding position of the seat plate is determined by the cutting surface of the mounting pipe, so if it fails to maintain a given height due to slight deformation during the manufacture of the mounting pipe, it cannot be cured during the welding process of the seat plate. Even if clearance is generated and it is inevitable to be dealt with, and even clearance is eliminated, it is difficult to maintain the horizontal level due to deformation of the seat due to heat of welding during welding of the seat. Many problems have been pointed out, such as stiffness deterioration and the bolt may easily loosen due to body vibration during vehicle operation, causing safety accidents.

본 발명은 상술한 바와 같은 종래의 문제점들을 해결하기 위하여 부품수와 용접면 및 작업공수를 줄여 생산성향상을 기대할 수 있도록 하면서도 마운팅 파이프 자체변형으로 인한 불량을 치유할 수가 있고 좌판은 상시 수평유지가능토록 용접해 줄 수가 있어 체결강성을 높이고 볼트이완에 의한 안전사고의 우려없이 안전하게 사용할 수 있는 자동차 서스펜션 멤버의 마운팅 파이프 구조를 제공하고자 한다.The present invention can be expected to improve the productivity by reducing the number of parts, welding surface and the number of work in order to solve the conventional problems as described above, while being able to heal the defects due to the self-deformation of the mounting pipe and to ensure that the seat plate is always horizontal It is intended to provide a mounting pipe structure for automobile suspension members that can be welded to increase fastening stiffness and can be safely used without fear of safety accidents caused by bolt loosening.

상기한 목적달성을 위하여 본 발명은 마운팅 파이프 단부에 결합공을 상하로 관통형성하여 상기 결합공에 플랜지 파이프를 결합한 다음 그 저부로 돌출된 돌출부를 마운팅 파이프와 용접하여 구성함을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that by forming a coupling hole through the mounting pipe end up and down to join the flange pipe to the coupling hole and then welded with the mounting pipe protruding to the bottom.

도 1은 본 발명의 정면구성도로서, 본 발명은 서스펜션 멤버(2)의 양측에 적정높이로 돌출형성되는 마운팅 파이프(4)(6) 단부에 상하로 결합공(8)을 관통형성하여 상기 결합공 상부로부터 플랜지 파이프(10)(12)를 결합하여 그 저부로 돌출된 돌출부를 플랜지 파이프(10)(12)에 용접고정하여 구성한다.1 is a front configuration diagram of the present invention, the present invention is formed by penetrating the coupling hole (8) vertically through the end of the mounting pipe (4) (6) which is formed to protrude to the appropriate height on both sides of the suspension member (2) The flange pipes 10 and 12 are coupled to each other from the upper side of the coupling hole and welded to the flange pipes 10 and 12 to protrude to the bottom thereof.

다만 이때 플랜지 파이프(10)(12)가 용접고정되는 마운팅 파이프(4)(6)의 단부중 그 상면은 가급적 본체(14)로부터 수평으로 이루는 평면을 갖도록 하여 플랜지 파이프(10)(12)의 플랜지(16)가 긴밀히 접촉할 수 있도록 하는 것이 바람직하다.However, at this time, the upper surface of the end of the mounting pipe (4) (6) to which the flange pipe (10) (12) is welded and fixed so that the upper surface of the flange pipe (10) (12) preferably has a plane made horizontally from the main body (14) It is desirable for the flange 16 to be in intimate contact.

그러나 그 상면은 본체(14)로부터 반드시 평면을 이루도록 해주어야만 만족한 결과를 얻을 수 있는 것은 아니며, 결합공(8)을 수직으로 관통형성하여 플랜지 파이프(10)(12)의 결합시 그 플랜지 (16)만 수평을 유지할 수 있도록 한 것이면 만족한다.However, the upper surface of the main body 14 must be flat to achieve a satisfactory result, and the coupling hole 8 is vertically formed to penetrate the flange pipe 10 and 12 so that the flange ( 16) Satisfy only if it is possible to keep level.

또한 플랜지 파이프(10)(12)의 결합시 그 플랜지(16)는 마운팅 파이프(4)(6)의 상면과 접하도록 한 상태에서 용접고정하는 것이 바람직하나 제조과정에서 마운팅 파이프(4)(6)의 변형으로 본체로부터 원하는 높이를 유지하지 못할 경우 미리 주어진 높이에 따라 마운팅 파이프(4)(6) 단부로부터 플랜지(16)를 돌출시켜서 용접고정해 줄 수도 있다.In addition, the flange 16 is preferably welded and fixed in a state in which the flange 16 is in contact with the upper surface of the mounting pipe 4 and 6 when the flange pipes 10 and 12 are coupled to each other. If the desired height cannot be maintained from the main body due to the deformation of), welding may be performed by protruding the flange 16 from the end of the mounting pipe 4 and 6 according to a predetermined height.

또한 플랜지 파이프(10)(12)의 용접시에는 마운팅 파이프(4)(6)의 결합공(8)을 관통시켜 그 하부로 일부돌출된 돌출부를 마운팅 파이프(4)(6)와 용접고정하여 구성하므로서 용접시 그 돌출부는 용접열에 의해 일부변형될 수 있다 하겠으나 플랜지(16)는 결합공(8)을 관통하는 원통부가 결합공에 지지됨에 따라 움직임이나 변형됨없이 정위치를 고수하게 되므로 용접과정에서 플랜지(16)가 기울거나 변형될 우려가 전혀 없게 된다.In addition, during welding of the flange pipes 10 and 12, the coupling holes 8 of the mounting pipes 4 and 6 are penetrated and welded and fixed to the mounting pipes 4 and 6 by protruding a part of the protrusions. Since the protrusions may be partially deformed by the welding heat during welding, the flange 16 retains its position without movement or deformation as the cylindrical portion passing through the coupling hole 8 is supported by the coupling hole. There is no fear that the flange 16 will tilt or deform.

이와 같이 발명은 마운팅 파이프(4)(6) 단부에 결합공(8)을 형성하여 그 상부로부터 플랜지 파이프(10)(12)를 결합한 다음 저부로 돌출된 돌출부를 이용하여 마운팅 파이프(4)(6)에 용접고정하여 구성하도록 하므로서 부품수와 용접면 및 작업공수를 줄일 수가 있어 생산성을 향상시켜 줄 수가 있고, 마운팅 파이프(4)(6)의 높낮이가 일정하지 않을 경우 플랜지 파이프(10)(12)의 용접에 앞서 마운팅 파이프 (4)(6) 단부로부터 플랜지 파이프(10)(12)의 높낮이를 조정하여 플랜지(16)가 원하는 높낮이를 갖도록 해주면 되므로 높낮이 차이로 인한 불량발생을 없애 줄수가 있으며, 플랜지 파이프(10)(12)의 용접시에도 플랜지(16)의 움직임이나 변형없이 수평되게 용접해 줄 수가 있어 차체와의 조립시 플랜지(16)가 차체의 평면부와 긴밀히 밀착될 수가 있어 볼트너트의 체결강성을 높여 줄 수가 있고, 이러한 높은 체결강성으로 인하여 운행중 차체진동에 의한 볼트의 이완우려없이 안심하고 사용할 수가 있는 유용한 발명인 것이다.In this way, the invention forms a coupling hole (8) at the end of the mounting pipe (4) (6) to join the flange pipe (10) (12) from the top and then to the mounting pipe (4) (using a protrusion projecting to the bottom) ( 6) It is possible to reduce the number of parts, the welding surface and the number of work by fixing the welding to be configured to improve the productivity, and if the height of the mounting pipes (4) and (6) is not constant, the flange pipe (10) ( Prior to welding of 12), it is necessary to adjust the height of the flange pipes 10 and 12 from the ends of the mounting pipes 4 and 6 so that the flange 16 has the desired height, thereby eliminating defects caused by the height difference. Also, even when the flange pipes 10 and 12 are welded, the flange 16 can be welded horizontally without moving or deforming the flange 16. Therefore, the flange 16 can be closely adhered to the flat part of the vehicle body when assembling the vehicle body. Bolt nut tightening It is possible to increase the rigidity, and because of this high fastening rigidity is a useful invention that can be used with confidence without fear of loosening of the bolts due to the vibration of the vehicle body during operation.
