Description

차량 현가장치의 콘트롤암과 부싱의 결합구조Combined structure of control arm and bushing of vehicle suspension

본 고안은 차량의 콘트롤암과 콘트롤암 부싱의 결합구조에 관한 것으로, 특히 콘트롤암의 연결단부가 그에 결합되는 부싱에 대하여 겉도는 것을 방지하여 궁극적으로 콘트롤암이 차체에 대하여 흔들리는 것을 방지함으로써 조향안정성 및 승차감을 향상시킨 콘트롤암과 콘트롤암 부싱의 결합구조에 관한 것이다.The present invention relates to a coupling structure of a control arm and a control arm bushing of a vehicle, and in particular, to prevent steering of the control arm from swinging with respect to the vehicle body by preventing the connecting end of the control arm from appearing on the bushing coupled thereto. The present invention relates to a control structure of a control arm bushing with improved ride comfort.

일반적으로, 자동차의 현가장치는 스티어링장치와 연동하게 되어 자동차의 승차감을 향상시킴과 아울러 자동차의 선회시 기울어짐을 감소시키도록 되어 있는 바, 노면에서의 충격을 흡수하는 스프링과, 스프링의 작동을 조정하는 쇽업소버 및, 바퀴의 작동을 제어하는 콘트롤암이나 링크로 구성되어 있다.In general, the suspension of the vehicle is linked with the steering system to improve the ride comfort of the vehicle and to reduce the inclination during the turning of the vehicle, and to adjust the operation of the spring and the spring to absorb the impact on the road surface. It consists of a shock absorber and a control arm or link that controls the operation of the wheel.

여기서, 상기 콘트롤암은 바퀴의 움직임을 콘트롤하는 팔의 역할을 하는 부재로서, 볼 조인트, 필로 볼, 고무 부싱 등에 의하여 차체 또는 차축에 부착되도록 되어 있다.Here, the control arm is a member serving as an arm that controls the movement of the wheel, and is attached to the vehicle body or the axle by a ball joint, a pillow ball, a rubber bushing, or the like.

즉, 상기 콘트롤암이 차체에 부착되기 위한 종래의 구조는 도 3에 도시된 바와 같이, 콘트롤암(11)의 체결부에 원통형의 바아(11a)가 돌출 형성되어, 이 바아(11a)에 외측이 고무로 이루어진 부싱(12)이 억지끼움식으로 끼워지고, 이렇게 콘트롤암(11)에 결합된 상기 부싱(12)은 쇽업소버(도시되지 않음) 등의 축이 삽입되어 콘트롤암(11)과 쇽업소버축을 연결시키는 것이다.That is, in the conventional structure for attaching the control arm to the vehicle body, as illustrated in FIG. 3, a cylindrical bar 11a protrudes and is formed outside the bar 11a. The rubber bushing 12 is fitted in an interference fit manner, and the bushing 12 coupled to the control arm 11 is inserted with a shaft such as a shock absorber (not shown) and the control arm 11 and the like. 것이다 Connect the absorber shaft.

상기와 같은 기능을 수행하도록 된 부싱(12)은 그 내부에 원형의 삽입홈(12a)이 형성되고, 이 삽입홈(12a)의 외측으로는 상기 콘트롤암(11)의 바아(11a)를 안착고정시켜 주도록 된 원형의 스틸 쉼(shim, 13)이 삽입고정되어 있는 구조이다.The bushing 12 is configured to perform a function as described above, a circular insertion groove 12a is formed therein, and the bar 11a of the control arm 11 is seated outside the insertion groove 12a. A circular steel shim (13) that is to be fixed is inserted and fixed.

그런데, 자동차가 주행하면서 바퀴의 회전운동에 의해 상기 콘트롤암(11)이 회전되는 경우, 상기 부싱(12)의 비틀림에 의하여 콘트롤암(11)의 회전이 가능하지만 잦은회전이나 외부의 진동에 의하여 콘트롤암(11)의 바아(11a)와 부싱(12)내부의 공차가 점점생기게 되어 콘트롤암(11)이 헛도는 현상이 발생되고, 이에따라 탑승객의 승차감이 저하됨과 더불어 조향안정성 또한 나빠지게 되는 문제점이 있었다.By the way, when the control arm 11 is rotated by the rotational movement of the wheel while the car is running, the control arm 11 can be rotated by the twisting of the bushing 12, but by frequent rotation or external vibration Tolerance between the bar 11a and the bushing 12 of the control arm 11 is increased, resulting in a phenomenon in which the control arm 11 is lost, thereby reducing the passenger's riding comfort and deteriorating steering stability. There was a problem.

이에 본 고안은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로, 콘트롤암의 바아와 이에 결합되는 부싱내부의 형상을 개선하여 콘트롤암과 부싱의 헛도는 현상을 방지해줌으로써 탑승객의 승차감이아 조향안정성을 향상시켜 주도록 된 차량 현가장치의 콘트롤암과 부싱의 결합구조를 제공하는 데 그 목적이 있다.The present invention has been devised to solve the above problems, and improves the shape of the control arm bar and the bushing coupled to the control arm, thereby preventing the control arm and the bushing from slipping, thereby improving the passenger comfort. The objective is to provide a coupling structure between the control arm of the vehicle suspension and the bushing to improve steering stability.

상기와 같은 목적을 달성하기 위한 본 고안은, 콘트롤암의 일단부에는 볼조인트가 체결됨과 더불어 이 볼조인트에 조향너클이 결합되고, 상기 콘트롤암의 중앙부 선단에 돌출된 바아가 부싱에 삽입되면서 이 부싱을 매개로 콘트롤암이 차체에 연결되도록 된 자동차의 현가장치에 있어서, 상기 콘트롤암의 바아가 사각형상의 봉으로 되어 상기 부싱의 체결부에 형성된 사각의 삽입홈에 끼워짐으로써 콘트롤암과 부싱의 회전을 구속할 수 있도록 된 구조이다.The present invention for achieving the above object, the ball joint is coupled to one end of the control arm, the steering knuckle is coupled to the ball joint, the bar protruding from the center end of the control arm is inserted into the bushing In a vehicle suspension system in which a control arm is connected to a vehicle body via a bushing, the bar of the control arm is formed into a rectangular rod and is fitted into a rectangular insertion groove formed at a fastening portion of the bushing. It is structure that can restrain rotation.

따라서, 차체에 체결되는 부싱의 내부에서 콘트롤암의 바아가 헛도는 현상이 발생되지 않도록 견고히 삽입되어, 현가장치의 내구성을 높여줌으로써 탑승객의 승차감을 높여주고 차량의 조향안정성을 좋게하는 것이다.Accordingly, the bar of the control arm is firmly inserted so that the bar of the control arm does not fall inside the bushing fastened to the vehicle body, thereby increasing the durability of the suspension device, thereby improving the riding comfort of the passengers and improving the steering stability of the vehicle.

이하 본 고안을 첨부한 예시도면을 참조로 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings of the present invention as follows.

도 1 는 본 고안에 따른 콘트롤암과 부싱의 결합구조가 적용된 현가장치의 부분 분해사시도이고, 도 2 는 콘트롤암과 부싱의 부분 분해사시도로서, 자동차의 현가장치를 이루는 콘트롤암(1)의 일단부에는 볼조인트(2)가 체결됨과 더불어 이 볼조인트(2)에 조향너클(3)이 결합되고, 상기 콘트롤암(1)의 중앙부 선단에 돌출된 사각형상의 바아(1a)가 부싱(4)의 체결부에 형성된 사각의 삽입홈(4a)에 끼워지며, 상기 부싱(4)의 삽입홈(4a) 외주면에 사각의 쉼(5)이 콘트롤암(1)과 부싱(4)의 회전을 구속하도록 삽입설치되어 있고, 상기 부싱(4)을 매개로 콘트롤암(1)이 차체에 연결되도록 된 구조이다.1 is a partially exploded perspective view of a suspension device to which a control structure of a control arm and a bushing according to the present invention is applied, and FIG. 2 is a partially exploded perspective view of a control arm and a bushing, and one end of a control arm 1 constituting a suspension device of a vehicle. The ball joint 2 is fastened to the part, and the steering knuckle 3 is coupled to the ball joint 2, and a rectangular bar 1a protruding from the center end of the control arm 1 is bushing 4 It is fitted into the rectangular insertion groove (4a) formed in the fastening portion of, the rectangular shim (5) on the outer peripheral surface of the insertion groove (4a) of the bushing (4) restrains the rotation of the control arm (1) and bushing (4). It is installed so that the control arm 1 is connected to the vehicle body via the bushing (4).

즉, 상기와 같이 스틸로 된 사각의 쉼(5)이 콘트롤암(1)의 바아(1a)를 압착하여 고정시켜주기 때문에 차량의 주행시에 비틀림이나 진동에 의해 바아(1a)와 부싱(4)사이에 틈새가 생겨나더라도 콘트롤암(1)과 부싱(4)이 서로 헛돌게 되는 것을 막아줄 수 있는 것이다.That is, as described above, the square shim 5 made of steel presses and fixes the bar 1a of the control arm 1, so that the bar 1a and the bushing 4 are caused by torsion or vibration during driving of the vehicle. Even if a gap is formed between the control arm (1) and the bushing (4) can prevent the mutual twist.

따라서, 상기 콘트롤암(1)의 바아(1a)와 부싱(4)내부의 체결홈이 사각으로 형성되어 체결부에 틈새가 생겨나도 서로 헛돌지 못하게 규제할 수 있게 되어, 콘트롤암(1)과 차체의 체결력을 강화시켜 줄 수 있는 것이다.Accordingly, the fastening grooves in the bars 1a and the bushings 4 of the control arm 1 are formed in a quadrangular shape, so that even if a gap is formed in the fastening portion, the control arm 1 and the control arm 1 can be restrained from turning. It can strengthen the fastening force of the body.

이상에서 설명한 바와 같은 본 고안에 따른 차량 현가장치의 콘트롤암과 부싱의 결합구조에 의하면, 차체에 체결되는 부싱의 내부에서 콘트롤암의 바아(1a)가 헛도는 현상이 발생되지 않도록 견고히 삽입되어, 현가장치의 내구성을 높여줌으로써 탑승객의 승차감을 높여주고 차량의 조향안정성을 좋게하는 효과가 있게 된다.According to the coupling structure of the control arm and the bushing of the vehicle suspension according to the present invention as described above, the bar (1a) of the control arm in the bushing fastened to the vehicle body is inserted firmly so that the phenomenon does not occur In addition, by increasing the durability of the suspension system, the ride comfort of the passengers is increased and the steering stability of the vehicle is improved.
