Description
본 발명은 자동차의 전방현가장치의 취부구조에 관한 것으로, 특히 스테빌라이저가 제거됨과 더불어 로어암이 브라켓트 및 판스프링을 매개로 크로스멤버에 취부되어져, 취부구조의 단순화로 인해 생산성이 향상됨은 물론, 작업효율이 증진되도록 된 자동차의 전방현가장치의 취부구조에 관한 것이다.The present invention relates to a mounting structure of the front suspension of a vehicle, in particular the stabilizer is removed and the lower arm is mounted to the cross member via the bracket and the leaf spring, the productivity is improved due to the simplification of the mounting structure, It relates to a mounting structure of the front suspension of the vehicle to improve the work efficiency.
일반적으로 현가장치는 차축과 차체를 연결하여 주행할 때 노면에서 받은 진동이나 충격을 차체에 직접 전달되지 않도록 하여 차체나 하물의 손상을 방지하고 승차감을 좋게 하는 장치로써, 전방현가장치는 도 1에 도시된 바와 같이, 노면에서 받는 충격을 완화하도록 된 코일스프링(1)과, 이 코일스프링(1)의 자유진동을 억제하여 승차감을 좋게 하도록 된 쇽업소버(2)와, 언더바디의 강도 및 강성을 증진시키도록 된 크로스멤버(3)와, 휠의 움직임을 조절하도록 된 위암과 아래암(4; 이하 로어암이라 함) 및, 자동차가 옆으로 흔들리는 것을 방지하도록 된 스테빌라이저(10)등으로 구성되어 있다.In general, the suspension device is a device that prevents damage to the vehicle body or the load and improves the riding comfort by not transmitting the vibration or shock received from the road surface directly when the vehicle is connected by connecting the axle and the vehicle body. As shown, the strength and stiffness of the coil spring 1 to alleviate the impact from the road surface, the shock absorber 2 to suppress the free vibration of the coil spring 1 to improve ride comfort, and the underbody. Crossmember (3) to enhance the movement, the upper and lower arms (4 (hereinafter referred to as the lower arm)) to adjust the movement of the wheel, stabilizer (10), etc. to prevent the vehicle from shaking sideways Consists of.
이러한 종래 전방현가장치의 취부구조는 도 2에 개략적으로 도시된 바와 같이, 차체에는 크로스멤버(3)가 취부되고, 이 크로스멤버(3)의 양측 끝부위에는 바퀴와 결합된 로어암(4)의 일측 끝부가 결합되며, 이 로어암(4)에는 스테빌라이저(10)의 양끝단이 취부된 구조로 되어 있다.As shown in FIG. 2, the mounting structure of the conventional front suspension device includes a cross member 3 mounted to a vehicle body, and a lower arm 4 coupled to wheels at both ends of the cross member 3. One end of the is coupled, the lower arm (4) has a structure in which both ends of the stabilizer 10 is mounted.
여기서, 상기 스테빌라이저(10)는 좌우바퀴의 움직임에 차이가 있을 때에 작용하는 바, 예를 들면, 코너링시 바깥쪽 바퀴가 부딪치거나 안쪽 바퀴가 튀어 올라올 때 좌우바퀴의 움직임을 같게 하여 차체의 기울기를 최소화시키도록 되어 있어 차체의 안정감을 향상시키도록 되어 있다.Here, the stabilizer 10 acts when there is a difference in the movement of the left and right wheels. For example, when the outer wheel collides or the inner wheel pops up during cornering, the right and left wheels are made equal to each other. Minimize the inclination to improve the stability of the car body.
그러나 종래의 스테빌라이저(10)는 크로스멤버(3)를 횡방향으로 가로질러 취부되므로 외관상 차체의 구조가 복잡해져 작업공정이 저하될 뿐만 아니라 특히 상기 스테빌라이저(10)의 중앙부위는 타부품과의 간섭발생으로 직선으로 제조되지 못하고 굴곡되게 형성되어 휠의 유동시 도 2에 점선으로 도시된 K부와 같이, 궤적을 형성하며 원운동하도록 되어 있어 상기 스테빌라이지(10)의 중앙부위에는 타부품과의 간섭발생을 방지하기 위해 일정한 공간이 형성되어 공간사용의 효율면에서 효율성이 저하되는 문제점이 있었다.However, since the conventional stabilizer 10 is mounted across the cross member 3 in the lateral direction, the structure of the vehicle body is complicated in appearance and the work process is reduced, and in particular, the central portion of the stabilizer 10 is compared with other components. Not be manufactured in a straight line due to the interference is formed to be curved, so as to move the wheel, as shown in the dashed line K in Figure 2, forming a trajectory and circular motion so that the other parts in the central portion of the stabilizer 10 and There is a problem in that a certain space is formed to prevent the occurrence of interference, the efficiency is reduced in terms of the efficiency of space use.
이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 스테빌라이저를 제거함과 더불어 상기 스테빌라이저와 동일한 기능을 수행하도록 된 판스프링을 크로스멤버에 취부시키고, 이 크로스멤버에 브라켓트를 매개로 로어암을 취부시켜, 취부구조의 단순화로 작업효율 및 생산성이 향상되도록 된 자동차의 전방현가장치의 취부구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and remove the stabilizer, and attaching a leaf spring to the cross member to perform the same function as the stabilizer, the lower through the bracket to the cross member An object of the present invention is to provide a mounting structure of a front suspension device of a vehicle in which an arm is mounted and the work efficiency and productivity are improved by simplifying the mounting structure.

It is attached to one side of the, and the opposite side of the bracket has a structure in which the lower arm is mounted.
이하 본 발명은 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 발명에 따른 전방현가장치의 요부확대도이고, 도 4는 도 3의 Ⅰ-Ⅰ선 부분단면도로서, 본 발명은, 노면에서 받는 충격을 완화하도록 된 코일스프링(1), 이 코일스프링(1)의 자유진동을 억제하여 승차감을 좋게 하도록 된 쇽업소버(2), 언더바디의 강도 및 강성을 증진시키도록 된 크로스멤버(3)와, 휠의 움직임을 조절하도록 된 로어암(4)으로 이루어진 자동차용 전방현가장치에 있어서, 상기 크로스멤버(3)의 양측 끝부위에는 탄성작용에 의해 자동차의 측방향 유동을 방지하도록 된 판스프링(5)이 취부되고, 이 판스프링(5)은 진동흡수부재인 고부재질의 부시(6)를 매개로 브라켓트(7)의 일측부와 취부되며, 이 브라켓트(7)의 반대측부에는 휠과 결합된 로어암(4)이 취부된다.Figure 3 is an enlarged view of the main portion of the front suspension according to the present invention, Figure 4 is a partial cross-sectional view of the line I-I of Figure 3, the present invention, the coil spring (1), the coil is designed to mitigate the impact received from the road surface A shock absorber (2) for suppressing free vibration of the spring (1) to improve ride comfort, a crossmember (3) for enhancing the strength and rigidity of the underbody, and a lower arm (4) for adjusting wheel movement. In the front suspension device for automobiles, the leaf springs (5) are mounted at both ends of the cross member (3) to prevent lateral flow of the vehicle by elastic action. Is mounted on one side of the bracket (7) via a high-quality bush (6), which is a vibration absorbing member, the lower arm (4) coupled with the wheel is mounted on the opposite side of the bracket (7).
따라서 휠과 결합된 로어암(4)이 브라켓트(7)를 매개로 크로스멤버(3)에 취부된 판스프링(5)에 취부되면, 휠의 구동시 측방향으로 유동되려는 자동차의 성질이 판스프링(5)에 의해 효과적으로 제어됨으로 인해 종래의 현가장치 구성품들중 스테빌라이저(10)가 제거되어도 상기 판스프링(5)이 스테빌라이저(10)의 기능을 용이하게 수행하게 되어 외관상 차체의 구조가 단순화되어진다.Therefore, when the lower arm 4 coupled with the wheel is mounted on the leaf spring 5 attached to the cross member 3 via the bracket 7, the nature of the car to be flowed laterally during driving of the wheel is the leaf spring. Effectively controlled by (5), even if the stabilizer 10 is removed from the conventional suspension components, the leaf spring 5 facilitates the function of the stabilizer 10, thereby simplifying the structure of the vehicle body. It is done.
이상 설명한 바와 같이 본 발명에 의하면, 노면에서 받는 충격을 완화하도록 된 코일스프링, 이 코일스프링의 자유진동을 억제하여 승차감을 좋게 하도록 된 쇽업소버, 언더바디의 강도 및 강성을 증진시키도록 된 크로스멤버와, 휠의 움직임을 조절하도록 된 로어암으로 이루어진 자동차용 전방현가장치에 있어서, 상기 크로스멤버의 양측 끝부위에는 판스프링이 취부되고, 이 판스프링의 중앙부위는 부시를 매개로 브라켓트의 일측부와 취부되며, 이 브라켓트의 반대측부에는 로어암이 취부되어져, 판스프링에 의해 측방향으로 유동되려는 자동차의 성질이 효과적으로 제어됨으로 인해 외관상 취부구조가 단순화되어 작업효율이 향상될 뿐만 아니라 이로 인해 생산성이 향상되는 효과가 있다.As described above, according to the present invention, the coil spring is designed to mitigate the impact on the road surface, the shock absorber designed to suppress the free vibration of the coil spring and improve the riding comfort, and the cross member, which is to enhance the strength and rigidity of the underbody. WHEREIN: In the front suspension device for automobiles which consists of the lower arm which adjusts the movement of a wheel, The leaf spring is attached to the both ends of the said cross member, The central part of this leaf spring is the one side part of a bracket via a bush.
