Description

차량의 로워암 구조{lower arm structure of a vehicle}Lower arm structure of a vehicle

본 발명은 차량의 현가장치를 이루는 로워암 구조에 관한 것으로서, 보다 상세하게는 로워암의 국부적인 강성을 증대시키도록 하는 기술에 관한 것이다.The present invention relates to a lower arm structure constituting the suspension of a vehicle, and more particularly, to a technique for increasing the local rigidity of the lower arm.

차량의 주행시 로워암은 노면으로부터 입력되는 하중을 너클을 통해 전달받아 차체와의 사이에 설치된 스프링을 통해 완충하도록 한다. 따라서, 상기 로워암에 일체로 구비되어 있는 스프링시트로는 차량의 상하방향으로 반복적인 하중이 가해지게 되며, 로워암은 이와 같은 하중에 대해 충분한 내구성능을 가져야 한다.When the vehicle runs, the lower arm receives the load input from the road surface through the knuckle to cushion the spring through the spring installed between the vehicle body. Therefore, the spring seat provided integrally with the lower arm is repeatedly loaded in the vertical direction of the vehicle, and the lower arm must have sufficient durability against such a load.

3개의 부품이 결합되어 이루어지는 3-피스형 로워암의 경우 어퍼판넬과 로워판넬 및 이들 사이에 끼워진 상태로 용접되는 스프링시트로 이루어지는데, 이와 같은 3-피스형 로워암의 경우에도 상기한 바와 같이 충분한 내구성능을 가지도록 해야 함은 물론이다.In the case of the three-piece lower arm formed by combining three parts, the upper panel and the lower panel and a spring sheet welded together are sandwiched between the three pieces. Of course, it should have sufficient durability.

본 발명은 3-피스형 로워암이 너클로부터 전달된 하중을 스프링을 통해 완충하면서 스프링시트를 통해 받게 되는 반복적인 하중에 대해 간단한 구조로 견고하고 안정성 있는 내구성능을 발휘할 수 있도록 한 차량의 로워암 구조를 제공함에 그 목적이 있다.The present invention provides a three-piece lower arm with a simple structure against the repetitive load received through the spring seat while buffering the load transmitted from the knuckle through the spring. The purpose is to provide a structure.

상기한 바와 같은 목적을 달성하기 위한 차량의 로워암 구조는, 어퍼판넬과 로워판넬 사이에 스프링시트가 개재되고, 상기 로워판넬에는 상기 스프링시트가 설치되는 부위에 차량의 전후 방향을 따라 길게 형성된 보강재가 더 설치된 구조의 3-피스형 로워암에 있어서, 상기 보강재는, 차량의 전후 방향을 따라 길게 형성된 보강부와, 상기 보강부 양측에 상기 로워판넬로 삽입되도록 돌출되어 형성된 삽입부와, 상기 삽입부에 돌출되게 형성되어 삽입부가 로워판넬에서 이탈되는 것을 방지하도록 하는 걸림돌기를 포함하여 구성되고; 상기 로워판넬에는 상기 삽입부가 삽입되도록 삽입홈이 형성된 것을 특징으로 한다.The lower arm structure of the vehicle for achieving the above object, the spring sheet is interposed between the upper panel and the lower panel, the lower panel is a reinforcement formed long along the front and rear direction of the vehicle at the site where the spring sheet is installed In the three-piece lower arm of the structure further installed, the reinforcement member, the reinforcement portion formed along the front and rear direction of the vehicle, the insertion portion formed to protrude so as to be inserted into the lower panel on both sides of the reinforcement portion, the insertion It is formed to protrude in the portion is configured to include a locking projection to prevent the insertion portion is separated from the lower panel; The lower panel is characterized in that the insertion groove is formed so that the insertion portion is inserted.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 따른 차량의 로워암(1) 구조를 도시한 사시도로서, 어퍼판넬(3)과 로워판넬(5) 사이에 스프링시트(7)가 개재되는 구조의 일반적인 3-피스형 로워암이 도시되어 있으며, 여기에 덧붙여, 상기 로워판넬(5)의 상기 스프링시트(7)가 설치되는 부위에 차량의 전후 방향을 따라 길게 형성된 보강재(9)가 더 설치되어 있다.1 is a perspective view showing a structure of a lower arm 1 of a vehicle according to the present invention, wherein a general three-piece lower structure having a spring seat 7 interposed between an upper panel 3 and a lower panel 5 is shown. The arm is shown, and in addition to this, a reinforcement member 9 formed along the front and rear direction of the vehicle is further installed at the site where the spring seat 7 of the lower panel 5 is installed.

여기서, 상기 어퍼판넬(3)과 로워판넬(5) 및 스프링시트(7)는 서로 용접에 의해 결합되어 있는 구조이며, 상기 보강재(9)는 삽입작업에 의해 장착되도록 되어 있다.Here, the upper panel (3), the lower panel (5) and the spring sheet (7) are connected to each other by welding, the reinforcement (9) is to be mounted by the insertion operation.

즉, 상기 보강재(9)는 차량의 전후 방향을 따라 길게 형성된 보강부(11)와, 상기 보강부(11) 양측에 상기 로워판넬(5)로 삽입되도록 돌출되어 형성된 삽입부(13)와, 상기 삽입부(13)에 돌출되게 형성되어 삽입부(13)가 로워판넬(5)에서 이탈되는 것을 방지하도록 된 걸림돌기(15)를 포함하여 구성되고, 상기 로워판넬(5)에는 삽입홈(17)이 구비되어, 상기 삽입부(13)를 상기 삽입홈(17)에 삽입하는 것만으로 로워암(1)에 보강재(9)를 설치할 수 있게 된 구조이다(도 2참조).That is, the reinforcing material (9) is a reinforcing portion (11) formed long along the front and rear direction of the vehicle, the insertion portion 13 formed to protrude so as to be inserted into the lower panel (5) on both sides of the reinforcing portion (11), It is formed to protrude in the insertion portion 13 is configured to include a locking projection (15) to prevent the insertion portion 13 from being separated from the lower panel (5), the lower panel 5 is an insertion groove ( 17 is provided, the reinforcing material (9) can be installed in the lower arm (1) only by inserting the insertion portion 13 into the insertion groove (17) (see Fig. 2).

물론, 일단 상기와 같이 로워암(1)에 상기 삽입부(13)가 삽입된 후에는 상기 걸림돌기(15)에 의해 상기 보강재(9)는 로워암(1)에서 이탈되지 않고 그 결합상태를 지속적으로 유지하게 된다.Of course, once the insertion portion 13 is inserted into the lower arm 1 as described above, the reinforcing material 9 is not separated from the lower arm 1 by the locking protrusion 15. It keeps going.

상기한 바와 같이 설치된 보강재(9)는 그 설치구조로도 알 수 있는 바와 같이 로워암(1) 스프링시트(7) 부분의 차량 전후방향에 대한 강성을 강화하도록 한다.The reinforcement 9 installed as described above is to strengthen the rigidity of the lower arm (1) spring seat 7 portion in the front and rear direction of the vehicle as can be seen also in the installation structure.

즉, 스프링으로부터 작용되는 반복적인 하중이 스프링시트(7)에 작용하면, 상기 스프링시트(7)와 일체로 용접되어 있는 어퍼판넬(3)은 차량 전후방향 양단이 하측으로 휘어지는 굽힘력을 받아 차량 전후 방향을 따라 인장되고, 상기와 같은 굽힘력에 의해 상기 로워판넬(5)은 차량 전후 방향을 따라 압축되는데, 이때, 상기와 같은 보강재(9)가 상기 로워판넬(5)의 압축변형을 방지하는 역할을 하게 되고, 이는 로워판넬(5) 및 어퍼판넬(3)의 변형을 최대한 억제하게 되어, 이들 로워판넬(5) 또는 어퍼판넬(3)의 변형에 의해 스프링시트(7)와의 용접부 파손이 발생되는 등의 문제를 사전에 방지할 수 있게 하므로 로워암(1)의 강성이 강화되는 것이다.That is, when the repetitive load acting from the spring acts on the spring seat 7, the upper panel 3, which is integrally welded with the spring seat 7, receives a bending force in which both ends of the front and rear directions are bent downward. The lower panel 5 is tensioned along the front and rear direction, and the lower panel 5 is compressed along the front and rear direction of the vehicle by the bending force as described above. In this case, the reinforcement 9 as described above prevents the compression deformation of the lower panel 5. This is to suppress the deformation of the lower panel (5) and the upper panel (3) to the maximum, and breakage of the weld portion with the spring sheet (7) by the deformation of the lower panel (5) or the upper panel (3). This can prevent problems such as occurring in advance, so that the rigidity of the lower arm 1 is enhanced.

상기한 바와 같은 보강재(9)는 그 설치작업이 용이할 뿐만 아니라, 기존의 3-피스형 로워암에 큰 변화를 주지 않고 용이하게 적용하여 그 강성을 강화시킬 수 있다.The reinforcing material 9 as described above is not only easy to install the work, but also can be easily applied to the existing three-piece lower arm without large change to enhance its rigidity.

이상과 같이 본 발명에 의하면, 3-피스형 로워암의 로워판넬에 간단한 구성의 보강재를 설치함으로써, 로워암이 너클로부터 전달된 하중을 스프링을 통해 완충하면서 스프링시트를 통해 받게 되는 반복적인 하중에 대해 견고하고 안정성 있는 내구성능을 발휘할 수 있도록 한다. According to the present invention as described above, by installing a reinforcing material of a simple configuration in the lower panel of the three-piece lower arm, the lower arm is subjected to the repetitive load received through the spring seat while buffering the load transmitted from the knuckle through the spring. It is to be able to show solid and stable durability.

도 2는 도 1의 로워판넬과 보강재의 결합상태를 도시한 도면이다.2 is a view showing a coupling state of the lower panel and the reinforcement of FIG.
