Description

자동차의 프론트 쇽업소버와 어퍼암 장착구조{a mounting structure of front shock absorber and upper arm in vehicles}A mounting structure of front shock absorber and upper arm in vehicles

본 발명은 자동차의 현가장치 설치구조에 관한 것으로, 특히 쇽업소버를 이용하여 독립현가장치를 구성한 자동차에서 프론트 쇽업소버의 상부와 어퍼암 차체측 두 단부의 장착구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension structure of an automobile, and more particularly, to a mounting structure of an upper end of a front shock absorber and two ends of an upper arm body in an automobile in which an independent suspension is configured using a shock absorber.

일반적으로 프론트 쇽업소버의 상부는 쇽업소버하우징에 장착되는데, 이 쇽업소버하우징은 휠하우징의 상부에 위치하며, 도 1에 도시된 바와 같이, 휀더 에이프런 인너패널(10)과 연계하여 하방이 개구된 박스형상으로 이루어진다.In general, the upper portion of the front shock absorber is mounted on the shock absorber housing, which is located on the upper part of the wheel housing, and as shown in FIG. 1, the lower portion of the front shock absorber is opened in connection with the fender apron inner panel 10. It consists of a box shape.

한편, 쇽업소버(50)의 상부는 상단에 장착된 어퍼브라켓(51)의 3지점이 볼트(52)와 너트를 매개로 상기 쇽업소버하우징의 어퍼패널(30)에 고정됨으로써 차체측에 장착되는데, 그 장착부의 강도를 보강하기 위하여 상기 어퍼패널(30)의 하면에는 커버(40)가 동시에 장착된다.(도 1, 도 2 동시참조)On the other hand, the upper part of the shock absorber 50 is mounted on the vehicle body side by fixing the three points of the upper bracket 51 mounted on the upper end to the upper panel 30 of the shock absorber housing through the bolt 52 and the nut. In order to reinforce the strength of the mounting portion, the cover 40 is simultaneously mounted on the lower surface of the upper panel 30. (See FIG. 1 and FIG. 2 simultaneously.)

또한, 외측 일단이 너클의 상부에 장착되고 나머지 두 단부가 차체측에 장착되는 구조로 설치되어 로워암과 더불어 차륜을 승강가능한 상태로 지지해주는 어퍼암의 상기 차체측 두 단부(91,92)는 도 3에 도시된 바와 같이, 쇽업소버하우징의 어퍼패널(30)과 로워패널(20)에 상하단이 용접된 마운팅브라켓(61,62)과 상기 어퍼패널(30)에 관통장착(상단에 볼트가 형성되어 관통후 너트로 조여짐)된 어퍼암샤프트(71,72)에 볼트(81,82)와 너트를 매개로 장착된다.(상기 두 단부(91,92)에는 부시가 구비되어 있어 볼트(81,82)를 중심으로 두 단부(91,92)는 회동가능하다.)In addition, the two end parts 91 and 92 of the upper arm of the upper arm, which are mounted to the upper end of the outer end and the other two ends are mounted to the vehicle body side, support the wheel with the lower arm in a liftable state. As shown in Figure 3, the upper and lower ends of the upper panel 30 and the lower panel 20 of the shock absorber housing and the mounting bracket (61, 62) and through-mounted on the upper panel 30 (bolt at the top) And the bolts 81 and 82 and the nuts are mounted on the upper arm shafts 71 and 72 which are formed and tightened with nuts after being penetrated. (The two ends 91 and 92 are provided with bushes. 81, 82, the two ends 91, 92 are rotatable.)

상기와 같은 구조에 의하여 쇽업소버(50)의 상단에 차체가 지지되고, 차륜이 설치되는 너클이 상하이동하능하게 되어 쇽업소버(50)를 통한 충격흡수작용이 이루어지게 된다.By the structure as described above, the vehicle body is supported on the upper end of the shock absorber 50, and the knuckle to which the wheel is installed becomes shanghai-dong, so that the shock absorbing action is performed through the shock absorber 50.

그런데, 상기와 같은 종래 구조에서는 쇽업소버(50)의 상단과 어퍼암의 두 단부(91,92)가 모두 쇽업소버하우징의 어퍼패널(30)에 장착되기 때문에, 어퍼패널(30)에 과도한 하중이 가해져 용접부에 크랙이 발생하는 등의 강성부족 문제가 발생하였다.However, in the conventional structure as described above, since both the upper end of the shock absorber 50 and the two end portions 91 and 92 of the upper arm are mounted on the upper panel 30 of the shock absorber housing, the upper panel 30 is excessively loaded. This caused a problem of insufficient rigidity such as cracking in the weld zone.

그럼에도 불구하고, 상기 어퍼패널(30)의 강성보강을 위하여 설치된 커버(40)는 어퍼패널(30)의 하면만을 덮는 한정된 크기로 형성되어 있어 단순히 쇽업소버(50) 상단의 체결부 강도만을 보강할 수 있도록 되어 있어서, 상기 어퍼암의 단부(91,92)가 장착됨으로써 필요한 강도의 보강은 고려되지 않고 있는 실정이다.Nevertheless, the cover 40 installed for rigidity reinforcement of the upper panel 30 is formed in a limited size covering only the lower surface of the upper panel 30 so that only the strength of the fastening portion of the upper end of the shock absorber 50 may be reinforced. Since the upper ends 91 and 92 of the upper arms are mounted, reinforcement of necessary strength is not considered.

또한, 상기 볼트(81,82)들에 너트를 체결하는 작업을 좁은 쇽업소버하우징 내부에서 수행하여야 했기 때문에 작업이 매우 불편하다는 문제점도 있었다.In addition, there was also a problem that the work is very inconvenient because the work to fasten the nut to the bolts (81, 82) had to be performed inside the narrow shock absorber housing.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 커버에 의한 쇽업소버하우징 어퍼패널의 강성보강이 보다 확실히 이루어지고, 또한 어퍼암의 차체측 두 단부를 장착하는 위치를 변경함으로써 쇽업소버하우징에 가해지는 하중이 분산되도록 함으로써 쇽업소버와 어퍼암이 보다 안정적으로 장착될 수 있도록 된 자동차의 프론트 쇽업소버 및 어퍼암 장착구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the rigidity of the shock absorber housing upper panel by the cover is made more secure, and the shock absorber by changing the position to mount the two end of the body side of the upper arm It is an object of the present invention to provide a front shock absorber and upper arm mounting structure of a vehicle in which the shock absorber and the upper arm can be mounted more stably by distributing the load applied to the housing.

상기와 같은 목적을 달성하기 위한 본 발명은, 휀더 에이프런 인너패널에 어퍼패널과 로워패널이 용접되어 박스형상으로 형성되고, 강성보강용의 커버가 상기 어퍼패널의 하면에 구비되어 이루어진 쇽업소버하우징에 쇽업소버의 상단과 어퍼암의 차체측 두 단부가 장착되는 자동차의 프론트 쇽업소버와 어퍼암 장착구조에 있어서, 상기 커버의 후단이 연장되어 상기 휀더 에이프런 인너패널의 측면에 용접되고, 이 커버를 사이에 두고 상기 어퍼패널에 쇽업소버의 상단이 장착되며, 상기 로워패널의 전면 양측에 마운팅브라켓이 용접되고, 이 마운팅브라켓들에 어퍼암의 두 단부가 볼트와 너트를 매개로 체결되는 것을 특징으로 한다.The present invention for achieving the above object, the upper panel and the lower panel is welded to the fender apron inner panel is formed in a box shape, the cover for rigid reinforcement is provided in the shock absorber housing is provided on the lower surface of the upper panel In the front shock absorber and upper arm mounting structure of a vehicle in which an upper end of an absorber and two end portions of an upper arm are mounted, the rear end of the cover is extended to be welded to the side of the fender apron inner panel, and the cover is interposed therebetween. The upper end of the shock absorber is mounted to the upper panel, and mounting brackets are welded to both sides of the front panel of the lower panel, and two ends of the upper arm are fastened to the mounting brackets via bolts and nuts.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

본 발명의 쇽업소버하우징은 상부를 구성하는 어퍼패널(30)과 이 어퍼패널(30) 하부 3면을 둘러싸는 로워패널(20)이 휀더 에이프런 인너패널(10)에 용접되어 하부가 개구된 박스형상으로 이루어진다.In the shock absorber housing of the present invention, an upper panel 30 constituting an upper part and a lower panel 20 surrounding three lower surfaces of the upper panel 30 are welded to the fender apron inner panel 10 to open the lower part of the box. It is made of a shape.

상기 어퍼패널(30)의 하면에는 커버(40)가 구비되는데, 이 커버(40)는 어퍼패널(30)의 하부면적을 커버하는데 그치지 않고 그 후단이 상기 휀더 에이프런 인너패널(10)측으로 연장되어 그 측면에 용접된다.A cover 40 is provided on a lower surface of the upper panel 30, and the cover 40 does not cover the lower area of the upper panel 30, but a rear end thereof extends toward the fender apron inner panel 10. It is welded to its side.

즉, 도 4에 도시된 바와 같이, 상기 어퍼패널(30)의 후단은 휀더 에이프런인너패널(10)의 상면에 용접되고, 커버(40)의 후단은 휀더 에이프런 인너패널(10)의 측면에 용접된다.That is, as shown in FIG. 4, the rear end of the upper panel 30 is welded to the upper surface of the fender apron inner panel 10, and the rear end of the cover 40 is welded to the side of the fender apron inner panel 10. do.

또한, 상기 커버(40)의 연장부 중간에는 하방으로 돌출되는 비드(41)가 형성되어 전후방향(상기 비드(41)의 축방향)으로의 강성을 보강하게 된다.In addition, a bead 41 protruding downward is formed in the middle of the extension of the cover 40 to reinforce the rigidity in the front-rear direction (axial direction of the bead 41).

상기와 같은 상태에서 종래와 동일한 방식으로 어퍼브라켓(51)의 3지점이 볼트(52)와 너트를 매개로 상기 어퍼패널(30)에 고정됨으로써 쇽업소버(50)의 상부가 쇽업소버하우징에 장착된다.In the same state as above, three points of the upper bracket 51 are fixed to the upper panel 30 via the bolt 52 and the nut in the same manner as in the prior art, so that the upper portion of the shock absorber 50 is mounted on the shock absorber housing. do.

한편, 종래기술에서 설명한 바와 같이, 차륜측 중앙 단부(93)가 너클의 상단에 체결되는 어퍼암(90)의 차체측 두 단부(91,92)는 도 5에 도시된 바와 같이, 쇽업소버하우징의 로워패널(20) 전면(내측) 양측의 모서리부에 용접되는 마운팅브라켓(101,102)에 볼트(81,82)와 너트를 매개로 체결된다.Meanwhile, as described in the related art, the vehicle body side two ends 91 and 92 of the upper arm 90 to which the wheel side center end 93 is fastened to the upper end of the knuckle are shock absorber housings as shown in FIG. The lower panel 20 is fastened to the mounting brackets 101 and 102 welded to the corners of both sides of the front (inner side) through the bolts 81 and 82 and the nuts.

따라서, 상기 커버(40)에 의하여 상기 어퍼패널(30)의 강성이 보다 향상됨과 더불어 상기 어퍼암(90)의 두 단부(91,92)가 어퍼패널(30)이 아닌 로워패널(20)에 장착되어 어퍼패널(30)에 집중되던 하중이 쇽업소버하우징 전체로 분산됨으로써 쇽업소버하우징이 강성측면에서 안정되게 된다.Therefore, the rigidity of the upper panel 30 is further improved by the cover 40, and the two ends 91 and 92 of the upper arm 90 are provided to the lower panel 20 instead of the upper panel 30. The load absorbed by the upper panel 30 is concentrated throughout the shock absorber housing so that the shock absorber housing is stabilized in terms of rigidity.

한편, 상기 어퍼암(90)의 두 단부(91,92)를 장착하는 두 볼트(101,102)는 로워패널(20)의 측면 외측으로 관통되어, 상기 너트들이 쇽업소버하우징의 외측에 위치하게 되는데, 이 두 볼트(101,102)들이 쇽업소버하우징의 외측으로 지나치게 돌출되는 것을 방지하기 위하여 도 6에 도시된 바와 같이, 볼트공(103)의 주위를 내측으로 오목하게 형성하여 너트의 체결위치를 안쪽으로 이동시킬 수 있도록 하고있다.On the other hand, the two bolts (101, 102) for mounting the two ends (91, 92) of the upper arm (90) penetrates to the outer side of the lower panel 20, the nuts are located outside the shock absorber housing, In order to prevent the two bolts 101 and 102 from protruding excessively to the outside of the shock absorber housing, as shown in FIG. 6, the bolt hole 103 is formed to be recessed inward to move the tightening position of the nut inward. I'm going to let you.

그러나, 이와 같이 볼트공(103)의 주변 부분만 오목하게 형성할 경우 이 부분에 국부적으로 하중이 집중되어 쇽업소버하우징 전체적인 강성이 저하될 수 있으므로, 도 7에 도시된 바와 같이 볼트공(103)의 하부 전체를--로워패널(20)의 하단에 이르는 부분까지--오목하게 형성하여 하중을 분산에 보다 유리한 형상을 취할 수도 있다.However, when only the peripheral portion of the bolt hole 103 is concave in this manner, since the load is concentrated locally on the portion, the overall rigidity of the shock absorber housing may be lowered, as shown in FIG. 7. The whole of the lower part of the lower portion of the lower panel 20 to the lower part of the lower panel 20 may be formed in a concave shape to take a more favorable shape for distributing the load.

한편, 상기 어퍼암(90)의 두 단부(91,92)가 장착되는 마운팅브라켓(101,102)을 상기와 같이 로워패널(20)에 한정하여 용접하지 않고, 그 상단을 연장절곡하여 어퍼패널(30)측 즉, 상기 커버(40)의 하면에 용접하면 이 커버(30)는 전면과 측면 뿐만 아니라 그 상부도 쇽업소버하우징에 장착됨으로써 그 장착상태가 보다 견고해질 뿐만 아니라, 쇽업소버하우징의 강성을 보강하는데도 일조하게 된다.On the other hand, without mounting the mounting brackets (101, 102) on which the two ends (91, 92) of the upper arm (90) are mounted to the lower panel (20) as described above, the upper end is extended and bent to the upper panel (30). If the cover 30 is welded to the lower surface of the cover 40, the cover 30 is mounted on the shock absorber housing, as well as the front and side surfaces thereof, so that the mounting state thereof is not only firm, but also the rigidity of the shock absorber housing is achieved. It also helps to reinforce.

이상 설명한 바와 같이 본 발명에 따르면, 커버 후단의 연장·용접으로 쇽업소버하우징 자체의 강성이 보강됨은 물론, 어퍼암이 쇽업소버하우징의 상면이 아닌 측면에 장착됨으로써 어퍼패널측으로 집중되던 하중이 쇽업소버하우징 전체로 분산됨으로써 구조적 측면에서의 강성이 보다 향상되는 효과가 있다.As described above, according to the present invention, the rigidity of the shock absorber housing itself is reinforced by the extension and welding of the rear end of the cover, and the upper arm is mounted on the side of the shock absorber housing instead of the upper surface, so that the load concentrated on the upper panel side is absorber. Dispersion throughout the housing has the effect of improving the rigidity in terms of structure.

또한, 어퍼암의 차체측 두 단부를 장착시키는 볼트에 체결되는 너트가 쇽업소버하우징의 외측에 위치하게 됨으로써 종래 쇽업소버하우징의 내측에서 너트를 체결할때에 비하여 체결작업이 용이해지게 되는 이점도 있다.In addition, since the nut is fastened to the bolt for mounting the vehicle body side two ends of the upper arm is located outside the shock absorber housing, there is an advantage that the fastening operation is easier than when the nut is fastened inside the shock absorber housing. .
