본 고안은 판스프링을 이용한 자동차의 로워암 지지용 부싱에 관한 것으로서, 더욱 상세하게는 자동차의 로워암을 지지하는 부싱 내부에 고무와 판스프링을 적절히 조화시켜 구성하므로써 내구성 개선과 노화방지를 통해 구조적 성능을 개선시킨 개량된 로워암 지지용 부싱에 관한 것이다.The present invention relates to a bushing for supporting the lower arm of an automobile using a leaf spring, and more specifically, by combining rubber and leaf spring in a bushing for supporting the lower arm of the automobile, it is structurally improved by improving durability and preventing aging. An improved lower arm support bushing with improved performance.
자동차의 로워암은 제1도에 도시한 바와 같은 지지부싱이 결합된 구조로서, 기존의 로워암은 부싱 내부가 G점을 중심으로 고무로 구성되어 있었다.The lower arm of the automobile is a structure in which a support bushing as shown in FIG. 1 is combined, and the conventional lower arm is made of rubber around the point G inside the bushing.
그러나, 이러한 종전의 고무부싱은 내구력이 좋지 못하고 차량의 운행시간이 경과함에 따라 노화되어 내구력이 크게 저하되는 문제가 있다. 따라서 부싱과 관련된 스프링 상수인 K값이 변화되어 차량 설계시에 고려되었던 여러가지 성능들이 저하되는 문제가 발생되었다. 특히, 차량의 오랜 사용으로 충격이 계속적으로 가해지면 부싱의 축방향과 횡방향으로의 회전변위가 제대로 관리되지 못하여 성능저하가 가속되고 이에 따라 승차감도 나빠지게 된다.However, the conventional rubber bushing has a problem that the durability is not good and the durability is greatly reduced as the running time of the vehicle elapses. Therefore, the K value, a spring constant associated with the bushing, was changed, causing various performances that were considered in the design of the vehicle. In particular, if the impact is continuously applied due to the long use of the vehicle, the rotational displacement of the bushing in the axial direction and the lateral direction is not properly managed, and thus the performance degradation is accelerated, resulting in poor riding comfort.
또한 종래의 고무부싱은 제작과정에서 컴플라이언스(compliance) 설정이 용이하지 못하여 초기 제작단계부터 정교한 관리가 어려운 근본적인 문제도 있었다.In addition, the conventional rubber bushing has a fundamental problem that it is difficult to precisely manage from the initial manufacturing stage because the compliance (compliance) is not easy in the manufacturing process.
따라서, 본 고안은 이러한 종래의 문제점을 일거에 해소하기 위해 안출한 것으로서, 로워암의 지지부싱을 고무소재와 판스프링의 조화로운 구성으로 제작하므로써 내구성 개선과 노화방지 및 설계균형의 유지 등에 우수한 효과가 있는 로워암 지지부싱을 제공하는데 그 목적이 있다.Therefore, the present invention has been devised to solve such a conventional problem at once, and by producing a support bushing of the lower arm in a harmonious configuration of a rubber material and a leaf spring, it has excellent effects such as durability improvement, anti-aging and maintenance of design balance. The purpose is to provide a lower arm support bushing.
이하, 본 고안의 구성을 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention in detail as follows.
본 고안은 자동차의 전방 로워암 지지용 부싱에 있어서, 부싱하우징(1) 내부에 제 1 판스프링(2)을 부싱하우징(1) 벽면을 따라 원호를 그리며 설치하고 그 반대로 제 2 판스프링(3)을 원호를 그리며 설치하되 제 1 판스프링(2)의 양끝부분이 제 2 판스프링(3)에 의해 중첩되도록 하고, 제 2 판스프링(3)에 의해 중첩되지 않은 부분에 제 1 고무부재(4)를, 그와 대칭방향에는 제 2 고무부재(5)를 설치하여 양측에서 로워암 축(6)을 감싸는 형태로 설치하여서 이루어진 것을 그 특징으로 한다.According to the present invention, in a bushing for supporting a front lower arm of a vehicle, a first leaf spring (2) is installed inside the bushing housing (1) by drawing an arc along the wall of the bushing housing (1) and vice versa. ) Is installed in an arc, so that both ends of the first leaf spring (2) overlap by the second leaf spring (3), and the first rubber member () in the portion not overlapped by the second leaf spring (3). 4), characterized in that the second rubber member (5) in the symmetrical direction and installed in a form surrounding the lower arm shaft (6) on both sides.
미설명 부호 7a, 7b, 7c는 각각 공간부이고, 8은 부싱하우징(1)과 제 1 판스프링(2) 사이에 생긴 틈새이고, 9는 제 1 판스프링(2)과 제 2 판스프링(3)과의 중첩부위에 생긴 틈새이다.Reference numerals 7a, 7b, and 7c denote spaces, respectively, 8 denotes a gap between the bushing housing 1 and the first leaf spring 2, and 9 denotes the first leaf spring 2 and the second leaf spring ( It is a gap in the overlapping area with 3).
이와같은 본 고안을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.
본 고안은 제1도에 도시한 바와 같은 자동차의 전방 로워암을 지지하기 위한 부싱의 구조를 새롭게 한 것으로서, 제2도에 도시한 바와같이 부싱하우징(1)의 내부에 2개의 판스프링(2,3) 양측에서 부싱하우징(1) 벽면을 따라 원형으로 중첩삽입하고, 2개의 고무부재(4,5)를 각각 판스프링(2,3)이 중첩되지 않는 부위만큼 원호를 그리며 삽입하여 그 중앙부위에 위치되는 로워암 축(6)을 탄력 지지하도록 구성되어 있어서, 고무부재(4,5)의 장점과 판스프링(2,3)의 장점을 골고루 이용하므로써 부싱의 고질적 문제점이었던 내구력 개선 및 노화방지를 통해 구조적 성능을 개선시킬 수 있게 만들어진 것이다.The present invention is a new structure of the bushing for supporting the front lower arm of the vehicle as shown in FIG. 1, and as shown in FIG. 2, two leaf springs (2) inside the bushing housing (1). 3) Insert overlapping circularly along the wall of the bushing housing (1) from both sides, and insert two rubber members (4, 5) in a circular arc as long as the leaf springs (2, 3) do not overlap. It is configured to elastically support the lower arm shaft (6) located in the site, by using the advantages of the rubber members (4,5) and the advantages of the leaf springs (2,3) evenly to improve the durability and aging, which was a chronic problem of the bushing Prevention is designed to improve structural performance.
본 고안에서 사용된 제 1 판스프링(2)과 제 2 판스프링(3)은 그 각각의 스프링 상수(K)값이 같거나 다른 것을 임의로 선택함으로써 부싱의 콤플라이언스(compliance)를 설정하기가 용이해지므로 판스프링(2,3)의 철판두께의 선택에 따라 설계에 부합되게 이용될 수 있는 것이다.The first leaf spring (2) and the second leaf spring (3) used in the present invention are easy to set the compliance of the bushing by arbitrarily selecting the same or different respective spring constant (K) value As it is, the steel plate thickness of the leaf springs (2, 3) can be used according to the design according to the selection.
본 고안에 따르면 제2도에서 부싱의 특성상 G점을 중심으로 좌,우의 스프링 상수값(K) 즉, 제 1 판스프링(2)과 제 2 판스프링(3)의 철판두께를 달리하여 한쪽은 변위(△y1)가 작게 되도록 하고, 다른 한쪽은 그 변위(△y2)가 크게 되도록 하여 차량의 콤플라이언스 효과를 부여하는 작용을 할 수 있도록 설계하는 것이 용이하다.According to the present invention, the spring constant value (K) of the left and right springs, ie, the steel plate thicknesses of the first leaf spring 2 and the second leaf spring 3, is centered on the point G in view of the nature of the bushing. It is easy to design so that the displacement DELTA y 1 may be made small and the other side may make the displacement DELTA y 2 large to impart a compliance effect to the vehicle.
특히, 본 고안에 따르면 제 1 판스프링(2)은 그 중간부분에서 부싱하우징(1)과 틈새(8)를 갖고 있으며, 이와 동일한 방식으로 제 2 판스프링(3)은 제 1 판스프링(2)이 그리는 원호의 동심원보다 약간 안쪽으로 기울어진 타원형을 이루고 있어서 제 1 판스프링(2)과의 중첩부분에서 사이가 약간 벌어진 틈새(8)를 갖도록 한다. 또한, 제 1 고무부재(4)는 제 2 판스프링(3)의 양선단 사이의 길이보다 크지 않은 길이로 원호를 그리며 삽입하며, 제 2 고무부재(5)는 제 2 판스프링(3)의 안쪽에서 제 1 판스프링(1)의 양선단 사이의 길이와 같은 길이로 원호를 그리며 삽입되어 있다.In particular, according to the present invention, the first leaf spring 2 has a bushing housing 1 and a gap 8 in the middle portion thereof, and the second leaf spring 3 has a first leaf spring 2 in the same manner. ) Has an elliptical shape inclined slightly inward from the concentric circle of the circular arc, so as to have a gap 8 slightly open at the overlapping portion with the first leaf spring 2. In addition, the first rubber member 4 is inserted in an arc with a length not greater than the length between both ends of the second leaf spring (3), the second rubber member (5) of the second leaf spring (3) It is inserted in a circular arc with a length equal to the length between both ends of the first leaf spring (1) from the inside.
따라서, 로워암 축(6)의 움직임에 따라 제 1 판스프링(2) 방향의 틈새(8)에 의한 탄성공간과 공간부(7a)와 틈새(9)의 탄성공간에 의해 로워암을 탄력적으로 지지해주며, 또다른 공간부(7b, 7c)에 의해 제 1 판스프링(2)과 제 2 판스프링(3)의 탄력운동에 따른 스프링 선단의 이동을 원활하게 해주게 된다. 이때 틈새(8,9)에 의해 두개의 판스프링(2,3)의 변위가 탄력적으로 조절되게 된다.Therefore, as the lower arm axis 6 moves, the lower arm is elastically formed by the elastic space of the gap 8 in the direction of the first leaf spring 2 and the elastic space of the space portion 7a and the gap 9. It supports, and facilitates the movement of the tip of the spring according to the elastic movement of the first leaf spring (2) and the second leaf spring (3) by the other space (7b, 7c). At this time, the displacement of the two leaf springs (2,3) is elastically adjusted by the gap (8,9).
또한, 고무부재(4)가 제 1 판스프링(2)의 양선단 길이보다 길지 않도록 하므로서 제 2 판스프링(3)의 효과적인 변위 관리가 가능하게 된다.In addition, the rubber member 4 is not longer than the length of both ends of the first leaf spring 2, it is possible to effectively manage the displacement of the second leaf spring (3).
상술한 바와같이 본 고안은 종래의 고무부싱 소재와는 달리 2개의 판스프링과 2개의 고무부재의 절묘한 조화로 부싱을 구성하므로써 내구력 개선과 노화방지 및 구조적 성능을 개선시킨 효과가 있는 것이다.As described above, unlike the conventional rubber bushing material, the present invention has an effect of improving durability and anti-aging and structural performance by configuring the bushing in an exquisite combination of two leaf springs and two rubber members.
