본 고안은 자동차의 비구동륜 현가장치에 관한 것으로서, 보다 상세하게는 차체에 직접 장착되는 스프링의 상단부를 별도의 링크부재에 연결 장착하여 차륜을 통해 전달되는 충격이 이 링크부재간의 연계작동을 통하여 분산, 흡수될 수 있게 함으로써, 자동차의 승차감을 향상시킨 자동차의 비구동륜 현가장치에 관한 것이다.The present invention relates to a non-drive wheel suspension of an automobile, and more particularly, the upper end portion of a spring directly mounted on a vehicle body is connected to a separate link member, so that an impact transmitted through the wheel is distributed through the linkage operation between the link members. The present invention relates to a non-drive wheel suspension of an automobile, which is capable of being absorbed, thereby improving the riding comfort of the automobile.

일반적으로 자동차의 전륜 또는 후륜 중에서 비구동륜 현가장치의 구조는, 첨부도면 제1도에 도시된 바와같이, 차륜(10)이 설치 지지되는 너클(11)의 상,하측으로 각각 상부암(12)과 하부암(13)의 일단이 볼이음(14)을 통해서 연결되고, 상부암(12)과 하부암(13)의 다른 일단은 피벗이음(15)을 통해서 차체프레임(16)에 연결되는 한편, 차체프레임(16)과 하부암(13) 사이에는 쇽업소버(17) 및 스프링(18)이 연결 설치되는 구조로 이루어져 있다.In general, the structure of the non-drive wheel suspension device among the front wheels or the rear wheels of the vehicle is, as shown in FIG. 1 of the accompanying drawings, the upper arm 12 above and below the knuckle 11 on which the wheel 10 is installed and supported, respectively. And one end of the lower arm 13 is connected through the ball joint 14, and the other end of the upper arm 12 and the lower arm 13 is connected to the body frame 16 through the pivot joint 15. , Between the body frame 16 and the lower arm 13 has a structure in which the shock absorber 17 and the spring 18 are connected and installed.

그러나, 이러한 기존의 현가장치에서는 상기 스프링(18)이 차체프레임(16)에 직접 장착되어 있어서 차륜(10)으로 부터의 충격이 그대로 차체에 전달되어 승차감을 저하시키게 되는 결점이 있었다.However, in the existing suspension device, the spring 18 is mounted directly on the body frame 16, so that the impact from the wheel 10 is transmitted to the vehicle body as it is, thereby reducing the riding comfort.

즉, 차륜(10)의 상,하운동에 대한 스프링(18)의 탄성 변형량(예컨대, 압축량)의 비가 1보다 적기 때문에 차륜(10)의 상,하운동에 대해 스프링(18)에 발생되는 반력(이때의 반력은 차륜(10)을 통해 전달되는 충격량보다 크게 된다)이 차체프레임(16)에 전달되어 승차감을 떨어뜨리게 된다.That is, since the ratio of the elastic deformation amount (for example, the compression amount) of the spring 18 to the up and down movement of the wheel 10 is less than 1, the spring 18 is generated in the up and down movement of the wheel 10. The reaction force (the reaction force at this time is greater than the amount of impact transmitted through the wheel 10) is transmitted to the body frame 16 to reduce the ride comfort.

본 고안은 이와같은 점을 감안하여 안출한 것으로서, 상부암과 하부암 사이에서 별도의 링크부재를 너클에 연결 설치하고 이 링크부재에 스프링을 장착함으로써, 차륜의 상,하운동에 따른 스프링의 반력이 상기 링크부재의 연계 링크작동을 통해서 흡수될 수 있게 한 자동차의 비구동륜 현가장치를 제공하는데 그 목적이 있다.The present invention has been devised in view of the above, by installing a separate link member between the upper arm and the lower arm connected to the knuckle and mounting the spring on the link member, the reaction force of the spring according to the up and down movement of the wheel It is an object of the present invention to provide a non-drive wheel suspension of an automobile that can be absorbed through the linkage operation of the link member.

이하, 첨부도면을 참고하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 자동차의 비구동륜 현가장치에 있어서, 상기 현가장치의 상부암(12)과 하부암(13) 사이에 수평링크부재(20)를 설치하되, 이 수평링크부재(20)의 일측 선단은 피벗(15) 이음을 통해서 너클(11)에 연결되고 다른 일측선단은 자유단을 이루도록 설치하고, 상기 수평링크부재(20)와 하부암(13) 사이에 스프링(18)과 그 우측으로 수직링크부재(21)를 각각 수직 설치하여서 이루어진 것이다.The present invention is a non-drive wheel suspension of the vehicle, the horizontal link member 20 is installed between the upper arm 12 and the lower arm 13 of the suspension, one end of the horizontal link member 20 is The pivot 15 is connected to the knuckle 11 through the joint, and the other one end is installed to form a free end, and the spring 18 and the vertical link to the right between the horizontal link member 20 and the lower arm 13 are installed. The members 21 are vertically provided, respectively.

특히, 상기 스프링(18)의 상단부는 상기 수평링크부재(20)의 자유단에 고정장착되고, 상기 수직링크부재(21) 상,하단부는 수평링크부재(20)와 하부암(13)에 각각 피벗(15) 이음을 통해서 연결 설치된다.In particular, the upper end of the spring 18 is fixedly mounted to the free end of the horizontal link member 20, the upper and lower ends of the vertical link member 21 to the horizontal link member 20 and the lower arm 13, respectively Pivot 15 is installed through the joint.

여기서, 상기 스프링(18)은 수평링크부재(20)의 자유단 저면부와 하부암(13)의 상면부에 각각 형성되어 있는 스프링 장착요부(22)에 그 상,하단부가 각각 안착 고정되어 이탈되지 않도록 되어 있다.Here, the spring 18 is mounted on the spring mounting recess 22 formed at the free end bottom portion of the horizontal link member 20 and the upper surface portion of the lower arm 13, respectively, and the upper and lower ends thereof are fixed and separated from each other. It is not supposed to be.

또한, 본 고안의 현가장치에서는 상기 수평링크부재(20) 상에서 스프링 장착 위치에서부터 수직링크부재 연결위치까지의 거리(A)는 수직링크부재연결 위치에서부터 수평링크부재연결 위치까지의 거리(B) 보다 크거나 같게 이루어져 있어서, 즉 AB의 값을 갖도록 스프링(18)과 수직링크부재(21)가 설치되어 있어서, 차륜(10)의 상,하운동에 대한 스프링(18)의 압축량의 비가 1보다 크게 되고 따라서, 차륜(10)에 의해 전달되는 충격량보다 적은량의 스프링(18) 반력이 발생하게 된다.In addition, in the suspension device of the present invention, the distance A from the spring mounting position to the vertical link member connection position on the horizontal link member 20 is greater than the distance B from the vertical link member connection position to the horizontal link member connection position. Is greater than or equal to, i.e. A The spring 18 and the vertical link member 21 are provided so as to have a value of B, so that the ratio of the compression amount of the spring 18 to the up and down movement of the wheel 10 becomes larger than 1, and thus the wheel 10 The reaction force of the spring 18 is generated less than the amount of impact transmitted by).

한편, 본 고안의 현가장치에서의 쇽업소버(17)는 기존과 같이 차체프레임(16)에 직접 연결 설치할 수 있으며 상기 수평링크부재(20)에 스프링(18)과 함께 설치 할 수 있다.On the other hand, the shock absorber 17 in the suspension device of the present invention can be installed directly connected to the body frame 16 as in the conventional and can be installed with the spring 18 to the horizontal link member 20.

이와같이 구성된 본 고안의 작용효과를 설명하면, 주행시 노면으로부터의 충격에 의해 차륜(10)이 윗쪽 또는 아래쪽으로 운동하게 되면 이에 따라 상기 수평링크부재(20) 및 수직링크부재(21)도 연계적으로 작동되어 이때의 충격흡수를 위한 스프링(18)의 탄성변형을 유도하게 된다. 즉, 차륜(10)과 함께 너클(11)이 윗쪽으로 운동하면 여기에 연계 결속된 하부암(13)은 차체프레임(16)측의 피벗(15)이음을 통한 연결부를 중심으로 하여 상향 회전되면서 스프링(18)을 압축하게 되며, 상부의 수평링크부재(20)의 자유단은 수직링크부재(21)와 너클(11) 간의 연계적인 링크작용(예컨대, 평행사변형 형태를 이루게 되는)에 의해서 그 위치 변화가 없게 된다.Referring to the operation and effect of the present invention configured as described above, when the wheel 10 moves upward or downward due to the impact from the road surface while driving, the horizontal link member 20 and the vertical link member 21 are also linked in accordance with this. It is operated to induce the elastic deformation of the spring 18 for the shock absorption at this time. That is, when the knuckle 11 together with the wheel 10 moves upward, the lower arm 13 which is linked to and coupled thereto is rotated upward with respect to the connection part via the joint 15 of the body frame 16 side. The spring 18 is compressed, and the free end of the horizontal link member 20 on the upper side thereof is connected by the linking action (for example, in the form of a parallelogram) between the vertical link member 21 and the knuckle 11. There is no change of position.

이때의 스프링(18)의 압출량은 차륜(10)의 상,하운동량과 비교하여 볼 때 매우 작기 때문에, 이를 바꾸어 말하면 차륜(10)을 통해 전달되는 충격량에 비례하여 발생되는 스프링(18)의 반력이 적기 때문에 차체프레임(16)으로는 이 스프링(18)의 반력이 거의 전달되지 않는다.At this time, since the extrusion amount of the spring 18 is very small compared with the up and down movement amount of the wheel 10, in other words, the spring 18 generated in proportion to the amount of impact transmitted through the wheel 10 Since the reaction force is small, the reaction force of the spring 18 is hardly transmitted to the body frame 16.

따라서, 본 고안의 현가장치에서 스프링(18)은 기존의 현가장치에서 스프링(18)의 완충기능을 변함없이 갖게 함과 동시에 이때의 스프링(18)의 반력은 수평링크부재(20)를 통해서 억제, 흡수될 수 있게 함으로써, 보다 향상된 승차감을 얻을 수 있게 된다.Accordingly, in the suspension of the present invention, the spring 18 has the buffer function of the spring 18 unchanged in the existing suspension and at the same time, the reaction force of the spring 18 is suppressed through the horizontal link member 20. By being able to be absorbed, it is possible to obtain an improved riding comfort.

또한, 본 고안의 현가장치를 구성하게 되는 스프링(18)은 기존의 스프링(18)에 비해 적은 탄성계수를 갖게 할 수 있기 때문에 코일 스프링의 소선의 지름과 평균지름을 작게 할 수 있고 이에 따라 스프링(18)의 전체적인 중량감소 효과를 얻어 낼 수 있다.In addition, the spring 18 constituting the suspension device of the present invention can have a smaller modulus of elasticity than the existing spring 18, so that the diameter and the average diameter of the element wire of the coil spring can be reduced, and thus the spring The overall weight reduction effect of (18) can be obtained.

이상에서와 같이 본 고안은 차륜의 상,하운동에 따른 스프링의 반력을 차체에 직접 전달되지 않게 함으로써, 차량의 승차감을 향상시킬 수 있는 장점이 있다.As described above, the present invention has an advantage of improving the riding comfort of the vehicle by not directly transmitting the reaction force of the spring according to the up and down movement of the wheel to the vehicle body.
