Description
본 발명은 로어암과 볼 조인트 브래킷과의 체결구조를 개선하여 휠의 캠버 조정이 가능하도록 된 차량의 로어암 어셈블리에 관한 것이다.The present invention relates to a lower arm assembly of a vehicle which is capable of adjusting a camber of a wheel by improving a fastening structure between a lower arm and a ball joint bracket.
일반적으로, 차량의 현가장치는 차축과 차체를 연결하여 주행중에 차축이 노면으로부터 받는 진동이나 충격을 차체에 직접적으로 전달되지 않도록 제어하여 차체와 화물의 손상을 방지하고 승차감을 좋게 만들어 준다.In general, the suspension of the vehicle is connected to the axle and the body to control the vibrations or shocks received from the road surface to not directly transmitted to the vehicle body while driving to prevent damage to the body and cargo and make the ride feel good.
이러한 현가장치에 있어서 차체의 롤링(rolling) 현상을 방지해 주는 스태빌라이저(stabilizer)는 공개특허공보 제10-1999-20659호에 기재되어 있는 바와 같이 좌,우측의 로어암(lower arm)에 양단이 장착되어 좌우의 휠(Wheel)이 서로 동시에 상하운동하는 경우에는 작용하지 않지만, 좌우의 바퀴가 서로 상하운동하는 경우에는 비틀려져 그 때에 발생하는 스프링 복원력으로 차체의 기울기를 감소시키는 역할을 하고 있다.In such a suspension device, a stabilizer for preventing rolling of the vehicle body is provided at both ends of a lower arm on the left and right sides, as described in Korean Patent Publication No. 10-1999-20659. When the left and right wheels (Wheel) are mounted and do not simultaneously move up and down at the same time, the wheels are twisted when the left and right wheels move up and down to each other to reduce the inclination of the vehicle body by spring restoring force generated at that time.
한편, 공개실용공보 제20-1995-18419호에서는 차량의 현가장치에 구비되는 로어암과 볼 조인트(ball joint)의 결합구조가 제시되어 있는바, 이에 따르면 로어암의 일측단에 브래킷이 다수의 볼트를 통해 체결 고정되고, 상기 브래킷의 단부에는 조향너클(steering knuckle)과 연결되는 볼 조인트가 일체로 결합된 구조를 이루고 있다.On the other hand, Published Utility Model Publication No. 20-1995-18419 discloses a coupling structure of a lower arm and a ball joint provided in a suspension device of a vehicle, whereby a bracket is provided at one end of the lower arm. Fastening and fixing through the bolt, the end of the bracket is a ball joint that is connected to the steering knuckle (steering knuckle) is integrally coupled structure.
이와 같은 결합구조에 따라, 상기 볼 조인트는 로어암과 조향너클의 상하방향의 움직임과 조향 핸들을 꺽었을 때의 조향 너클의 회전 베어링의 기능을 겸하게 되며, 이러한 볼 조인트 취부구조에서는 타이로드(tie rod)를 통해 토인(toe-in)을 조정하게 된다. According to such a coupling structure, the ball joint serves as a vertical bearing of the lower arm and the steering knuckle and functions as a rotating bearing of the steering knuckle when the steering wheel is bent, and in this ball joint mounting structure, a tie rod (tie) is used. rod to adjust the toe-in.
그러나, 상기와 같은 종래 볼 조인트 취부구조는 볼 조인트가 구비된 브래킷을 로어암상에 볼트로 체결시킨 후에는 로어암에 대한 볼 조인트의 위치가 고정될 수 밖에 없기 때문에 필요시 휠의 캠버(camber) 조정이 불가능했던 문제점이 있었다.However, in the conventional ball joint mounting structure as described above, after the bolt having the ball joint is bolted onto the lower arm, the position of the ball joint with respect to the lower arm can only be fixed. There was a problem that adjustment was impossible.
이에, 본 발명은 상기한 종래의 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 로어암 본체 또는 볼 조인트가 결합되는 브래킷상에 길이조절용 슬롯을 형성하여 볼트 체결시 브래킷의 위치를 적절히 조절할 수 있도록 함으로써 로어암의 전체적인 길이를 휠의 캠버 조정을 자유롭게 수행할 수 있도록 하는 차량의 로어암 어셈블리를 제공함에 있다. Accordingly, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to form a slot for adjusting the length on the bracket to which the lower arm body or ball joint is coupled to properly adjust the position of the bracket when bolting It is possible to provide a lower arm assembly of a vehicle in which the overall length of the lower arm can be freely performed by adjusting the camber of the wheel.
상기한 목적을 달성하기 위한 본 발명의 로어암 어셈블리는 로어암 본체; 상기 로어암 본체와 결합되며 일단에 볼 조인트가 결합되는 브래킷; 및 상기 로어암 본체와 상기 브래킷를 체결하는 볼트를 포함하여 이루어지되, 상기 로어암 본체와 상기 브래킷중 적어도 일측에는 길이조절용 슬롯이 형성된 것을 특징으로 한다.Lower arm assembly of the present invention for achieving the above object is a lower arm body; A bracket coupled to the lower arm body and having a ball joint coupled at one end thereof; And a bolt for fastening the lower arm body to the bracket, wherein at least one side of the lower arm body and the bracket is provided with a slot for length adjustment.
이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조하여 상세하게 설명하면 다음과 같다. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 일실시예에 따른 로어암 어셈블리(lower arm assembly)의 결합구조를 도시한 사시도이고, 도 2는 도 1에 도시된 볼 조인트 브래킷의 체결위치 변화에 따른 로어암의 길이 조절예를 보여주는 예시도.1 is a perspective view illustrating a coupling structure of a lower arm assembly according to an embodiment of the present invention, and FIG. 2 is a length adjustment of a lower arm according to a change in a fastening position of a ball joint bracket shown in FIG. 1. An illustration showing an example.
도 1 및 도 2를 참조하면, 본 발명에 따른 로어암 어셈블리(500)는 로어암 본체(100)와, 상기 본체(100)와 체결되며 일단에 볼 조인트(300)가 결합되는 브래킷(200) 및 상기 브래킷(200)을 상기 본체(100)에 체결하는 볼트(400)를 포함한다.1 and 2, the lower arm assembly 500 according to the present invention is a lower arm main body 100, a bracket 200 coupled to the main body 100 and having a ball joint 300 coupled to one end thereof. And a bolt 400 for fastening the bracket 200 to the main body 100.
상기 브래킷(200)이 취부되는 본체(100)의 일측단에는 볼트(400)가 체결되는 좁고 긴 홀(hole) 형태를 갖는 다수의 길이조절용 슬롯(120)이 형성되어 있다.At one end of the main body 100 to which the bracket 200 is mounted, a plurality of length adjusting slots 120 having a narrow and long hole shape to which the bolt 400 is fastened are formed.
한편, 상기 본체(100)와 결합되는 상기 브래킷(200)상에는 길이조절용 슬롯(120)에 대응하여 볼트(400)가 체결되는 다수의 체결공(220)이 형성되어 있다.On the other hand, on the bracket 200 is coupled to the main body 100, a plurality of fastening holes 220 to which the bolt 400 is fastened corresponding to the length adjusting slot 120 is formed.
이러한 결합구조를 갖는 본 발명의 로어암 어셈블리(500)는 평상시 브래킷(200)과 로어암 본체(100)가 볼트(400) 및 너트(420)를 통해 조립된 상태가 된다.The lower arm assembly 500 of the present invention having such a coupling structure is normally in a state in which the bracket 200 and the lower arm main body 100 are assembled through the bolt 400 and the nut 420.
이 후, 차량의 휠(도시안됨) 캠버 조정이 필요한 경우 상기 조여진 상태의 볼트(400)를 느슨하게 푼 다음 브래킷(200)을 길이조절용 슬롯(120) 폭 내의 적절한 위치까지 이동하여 다시 조여주게 되면 로어암의 전체적인 길이(L)가 조절되어 휠의 캠버 조정이 가능해진다.Afterwards, if the wheel (not shown) of the vehicle camber adjustment is necessary, loosen the bolt 400 in the tightened state, and then move the bracket 200 to an appropriate position within the width of the slot 120 for adjustment. The overall length L of the arm is adjusted to allow adjustment of the camber of the wheel.
이상과 같은 본 발명의 일실시 예에서는 길이조절용 슬롯(120)을 로어암 본체(100)에 형성하고 체결공(220)을 브래킷(200)상에 형성였지만, 이와 반대로 상기 길이조절용 슬롯(120)을 브래킷(200)에 그리고 상기 체결공(220)을 본체(100)상에 변경 형성하여도 동일한 효과를 얻을 수 있다.In the embodiment of the present invention as described above, the length adjusting slot 120 is formed in the lower arm body 100 and the fastening hole 220 is formed on the bracket 200, but the length adjusting slot 120 is reversed. The same effect can be obtained by changing the fastening hole 220 on the bracket 200 and on the main body 100.
또한, 상기 본체(100)와 브래킷(200)상에 길이조절용 슬롯(120)을 모두 형성할 수도 있으며, 이렇게 되면, 로어암의 전체적인 가변 길이(L)를 더욱 크게 조절될 수 있을 것이다.In addition, both the length adjusting slot 120 may be formed on the main body 100 and the bracket 200. In this case, the overall variable length L of the lower arm may be further adjusted.
상술한 바와 같이, 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 해당 기술 분야의 숙련된 당업자는 하기의 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다.As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art various modifications of the present invention without departing from the spirit and scope of the invention described in the claims below And can be changed.
상술한 구성에 따르면, 로어암 본체 또는 볼 조인트가 장착된 브래킷상에 길이조절용 슬롯을 형성함으로써, 브래킷을 로어암 본체의 적절한 위치까지 이동시킨 후 볼트로 체결하게 되면 로어암의 전체 길이를 가변시킬 수 있기 때문에 차량 휠의 캠버 조정이 가능해진다. According to the above-described configuration, by forming a slot for adjusting the length on the lower arm body or the bracket on which the ball joint is mounted, moving the bracket to an appropriate position of the lower arm body and then tightening the bolt to change the overall length of the lower arm This makes it possible to adjust the camber of the vehicle wheel.
