Description

현가장치의 로어암용 부시Lower arm bush of suspension

본 고안은 현가장치의 로어암용 부시에 관한 것으로, 특히 제동안전성과 승차감을 향상시킬 수 있도록 된 현가장치의 로어암용 부시에 관한 것이다.The present invention relates to a lower arm bush of a suspension device, and more particularly to a lower arm bush of a suspension device that can improve the integrity and ride comfort of the suspension.

일반적으로 자동차의 현가장치는 차축과 차체를 연결하여 주행중에 차축이 노면으로부터 받는 진동이나 충격을 차체에 직접적으로 전달되지 않도록 제어하여 차체와 화물의 손상을 방지하고 승차감을 좋게 만드는 장치로서, 노면으로부터 충격을 완화시키는 섀시 스프링과, 섀시 스프링의 자유진동을 제어하여 승차감을 좋게 하는 쇽 업소버 및 차량의 롤링을 방지하는 스태빌라이저 등으로 구성된다.In general, the suspension system of a car connects the axle and the body so that the vibrations or shocks received from the road surface are not directly transmitted to the body while driving, thereby preventing damage to the body and cargo and improving ride comfort. It includes a chassis spring for mitigating impact, a shock absorber for controlling the free vibration of the chassis spring to improve ride comfort, and a stabilizer for preventing rolling of the vehicle.

그리고 상기 현가장치는 자동차의 장착부위에 따라 앞현가장치와 뒤현가장치로 구분되어지고, 상기 뒤현가장치는 평행 라이프 스프링형과 코일스프링형의 차축식과, 스윙 액슬형과 트레일링 아암형 및 세미 트레일링 아암형과 다이어고널 링크형의 독립식 및, 다수개의 링크로 결합되는 멀티링크형이 있다.The suspension is divided into front suspension and rear suspension according to the mounting part of the vehicle, and the rear suspension is axle type of parallel life spring type and coil spring type, swing axle, trailing arm type and semi There are independent types of trailing arm type and Diagonal link type, and multi-link type which are combined by multiple links.

여기서 상기 현가장치의 로어암(100)은 제1도에 도시된 것과 같이, 차체에 결합하기 위해 앞뒤에 설치된 부시(110, 120)와, 휠이 설치되는 너클에 결합하기 위한 볼조인트(130)가 구비되되, 상기 부시(120)는, 로어암(100)에 끼워지는 외측파이프(121)와, 차체에 결합되는 내측파이프(122) 및, 상기 외측파이프(121)와 내측파이프(122)를 연결하도록 된 방진러버(123)로 이루어져 있다.Here, the lower arm 100 of the suspension device, as shown in Figure 1, the bush 110, 120 installed in front and rear to couple to the vehicle body, and the ball joint 130 for coupling to the knuckle that the wheel is installed Is provided, the bush 120, the outer pipe 121 is fitted to the lower arm 100, the inner pipe 122 is coupled to the vehicle body, and the outer pipe 121 and the inner pipe 122 It is made of a dustproof rubber 123 to be connected.

따라서 상기 방진러버(123)에 의해 차량의 휠에 전후방향으로 작용되는 힘을 받을 때 이를 감쇠하게 된다.Therefore, when the vibration-resistant rubber 123 receives a force acting in the front and rear direction of the wheel of the vehicle it is attenuated.

그러나 이러한 부시(100)의 구조는, 횡코너링시 또는 요철통과시 좌우방향의 횡력을 부드럽게 감쇠시키지 못하는 결점이 있었다.However, the structure of the bush 100, there is a drawback that does not smoothly attenuate the lateral force in the lateral direction when transverse cornering or unevenness passes.

이에 본 고안은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 부시의 방진러버에 좌우측이 폭과 길이가 다른 구멍이 형성됨과 더불어, 폭이 좁은 구멍의 안쪽에 소정간격을 두고 인서트플레이트가 설치되어, 타이어에 입력되는 전후방향의 충격을 부드럽게 감쇠시키고, 구동력이 휠에 작용할 때 확실하게 잡아주어 직진 안전성이 향상되도록 된 현가장치의 로어암용 부시를 제공함에 그 목적이 있다.The present invention has been devised to solve the above drawbacks, the left and right sides of the bush is formed in the anti-vibration rubber of the bush and the insert plate is provided with a predetermined interval inside the narrow hole. It is an object of the present invention to provide a lower arm bush of the suspension device, which smoothly dampens the impact in the front and rear directions input to the tire and reliably catches it when the driving force acts on the wheel, thereby improving the safety of the straight line.

상기한 바의 목적을 달성하기 위한 본 고안은, 차체에 결합하기 위해 앞뒤에 설치된 부시와, 휠이 설치되는 너클에 결합하기 위한 볼조인트가 구비된 자동차용 현가장치의 로어암에 있어서, 상기 부시는, 로어암에 끼워지는 외측파이프와, 차체에 결합되는 내측파이프 및, 상기 외측파이프와 내측파이프를 연결함과 더불어 내측파이프의 좌우측에 폭과 길이가 다른 구멍이 형성된 방진러버와, 상기 내측파이프와 구멍의 사이에 일체성형된 인서트플레이트로 이루어진 구조로 되어 있다.The present invention for achieving the object of the above, in the lower arm of the suspension device for a vehicle provided with a front and rear bushing for coupling to the vehicle body, and a ball joint for coupling to the knuckle, the wheel is installed, the bush Is an outer pipe fitted to the lower arm, an inner pipe coupled to the vehicle body, a dustproof rubber having a hole having a different width and length from the left and right sides of the inner pipe, while connecting the outer pipe and the inner pipe, and the inner pipe. It consists of an insert plate integrally formed between the hole and the hole.

이하 본 고안의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 고안에 따른 로어암용 부시를 나타내는 단면도로서, 종래 기술을 설명하는 제1도 및 제2도와 동일한 부위에는 동일한 참조부호를 붙이면서 그 설명은 생략한다.Figure 3 is a cross-sectional view showing a lower arm bush according to the present invention, the same reference numerals are attached to the same parts as the first and second diagrams illustrating the prior art, the description thereof will be omitted.

본 고안은, 차체에 결합하기 위해 앞뒤에 설치된 부시(110, 120)와, 휠이 설치되는 너클에 결합하기 위한 볼조인트(130)가 구비된 현가장치의 로어암에 있어서, 상기 부시(200)는, 로어암(100)에 끼워지는 외측파이프(210)와, 차체에 결합되는 내측파이프(200) 및, 상기 외측파이프(210)와 내측파이프(220)를 연결함과 더불어 내측파이프(220)의 좌우측에 폭과 길이가 다른 구멍(231, 232)이 형성된 방진러버(230)와, 상기 내측파이프(220)와 구멍(232)의 사이에 일체성형된 인서트플레이트(240)로 이루어져 있다.The present invention, in the lower arm of the suspension device is provided with a bush (110, 120) installed in front and rear to couple to the vehicle body, and a ball joint (130) for coupling to the knuckle that the wheel is installed, the bush 200 The inner pipe 220 is connected to the outer pipe 210 fitted to the lower arm 100, the inner pipe 200 coupled to the vehicle body, and the outer pipe 210 and the inner pipe 220. The dustproof rubber 230 is formed with holes 231 and 232 having different widths and lengths on left and right sides thereof, and an insert plate 240 integrally formed between the inner pipe 220 and the holes 232.

다음에는 이상과 같이 구성된 본 고안의 작용과 효과에 대해 설명한다.Next, the operation and effects of the present invention configured as described above will be described.

상기 내측파이프(220)에 +P방향의 힘이 작용할 때 구멍(231)에 의해 제4도에 도시된 것과 같이 상당히 부드러운 특성곡선을 가지게 되고, 또 내측파이프(220)에 -P방향의 힘이 작용할 때 구멍(232)이 찌그러지는 짧은 구간에서는 부드럽지만 그 이후에는 인서트플레이트(240)에 의해 상당히 거친 특성을 보여 휠이 쉽게 토-인방향으로 회전되지 않아 직진 안전성이 향상된다.When a force in the + P direction is applied to the inner pipe 220, the hole 231 has a fairly soft characteristic curve as shown in FIG. 4, and a force in the -P direction is applied to the inner pipe 220. In the short section where the hole 232 is distorted when acting, it is soft, but after that, the insert plate 240 exhibits a very rough property, so that the wheel is not easily rotated in the toe-in direction, thereby improving the safety of going straight.

이상 설명한 바와 같이 본 고안에 따른 부시에 의하면, 타이어에 입력되는 전후방향의 충격을 부드럽게 감쇠시키고, 구동력이 휠에 작용할 때 확실하게 잡아주어 직진안전성이 향상되는 효과가 있다.As described above, according to the bush according to the present invention, the impact of the front and rear direction input to the tire is softly attenuated, and when the driving force acts on the wheel, the grip is secured, thereby improving the safety of going straight.

이상에서 본 고안의 구체적인 일 실시예를 상세히 설명하였으나, 본 고안은 이에 한정되는 것은 아니며, 이 분야의 통상의 지식을 가진 자라면 본 고안의 기술적 사상을 바탕으로 다양한 변경과 수정이 가능할 것이다.Although one specific embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and those skilled in the art may make various changes and modifications based on the technical idea of the present invention.
