Description
본 고안은 승용차 프론트 현가장치의 로워 암 리어 수직 부싱(Rear Vertical Bushing for Suspension Lower Arm)에 관한 것이다.The present invention relates to a lower vertical bushing for suspension lower arm of a passenger car front suspension.
종래의 로워 암 리어 수직 부싱은 도 1 및 도 2에서 보는 바와 같이 크로스 멤버에 고정되는 볼트가 끼워지는 내측 파이프(1)와, 로워 암(5)에 끼워지는 외측 파이프(2)의 사이에 하나의 피스(Piece)로 이루어진 러버(3)를 가황접착시킨 것으로, 이러한 로워 암 리어 수직 부싱의 러버(3)에는 양측에 수직방향으로 완충구멍(4a,4b)이 뚫려 있다.The conventional lower arm rear vertical bushing is one between an inner pipe 1 into which a bolt fixed to a cross member is fitted and an outer pipe 2 fitted to a lower arm 5 as shown in FIGS. 1 and 2. The rubber 3 made of a piece of vulcanized is vulcanized and bonded to the rubber 3 of the lower arm vertical bushing with buffer holes 4a and 4b vertically on both sides thereof.
상기 완충구멍(4a,4b)은 P방향으로 작용하는 작용하는 외력의 입력시에 그 완충력을 발휘하기 위하여 형성시킨 것이다.The buffer holes 4a and 4b are formed so as to exert the buffering force upon input of an external force acting in the P direction.
그러나, 상기와 같은 종래의 로워 암 리어 수직 부싱의 러버는 로워 암의 스트로크에 의하여 주어지는 Q방향으로의 굽힘모멘트를 받게 되면 그에 따른 적절한 완충작용을 제대로 수행하지 못하기 때문에 승차감이 비교적 떨어지게 되는 문제가 있었던 것이다.However, when the rubber of the conventional lower arm rear vertical bushing as described above is subjected to the bending moment in the Q direction given by the stroke of the lower arm, it does not properly perform a proper cushioning action, and thus the ride comfort is relatively poor. It was.
본 고안의 목적은 측방에서 작용하는 외력을 흡수하면서 로워 암의 스트로크에 의한 굽힘모멘트도 충분히 흡수할 수 있는 단면구조를 취하여 승차감을 향상시키고자 하는데 있는 것이다.An object of the present invention is to improve the riding comfort by taking a cross-sectional structure that can absorb the external force acting on the side while sufficiently absorbing the bending moment due to the stroke of the lower arm.

상기 목적을 달성하기 위한 본 고안의 구성을 첨부된 도 3 내지 도 5에 의하여 설명하면 다음과 같다.Referring to the configuration of the present invention for achieving the above object by the attached 3 to 5 as follows.
본 고안은 서로 일정 간격을 두고 분리된 제1러버(31)와 제2러버(32)를 구비하고, 이 중 제1러버(31)는 외측 파이프(33)의 상부 내면에 가황접착되며, 제2러버(32)는 상기 제1러버(31)와 일정 간격이 이격된 상태에서 내측 파이프(34)의 외면과 외측 파이프(33)의 내면 사이에 가황접착되고, 상기 제2러버(32)는 차량 내측으로 수직의 호형(弧形) 완충구멍(35)이 형성된 것이다.The present invention includes a first rubber 31 and a second rubber 32 separated from each other at a predetermined interval, wherein the first rubber 31 is vulcanized and bonded to the upper inner surface of the outer pipe 33. The second rubber 32 is vulcanized and bonded between the outer surface of the inner pipe 34 and the inner surface of the outer pipe 33 in a state where a predetermined distance is separated from the first rubber 31, and the second rubber 32 is A vertical arc-shaped buffer hole 35 is formed inside the vehicle.
상기한 제1러버(31)와 제2러버(32)는 도 3의 A방향에서 보면 도 4와 같이 완전히 분리되어 있는 것으로, 그 이격된 간격은 도 3에서 표시하는 바와 같이 δ의 간격을 갖는다. 또 도 3에서와 같이 우측을 차량외측이라고 보고, 좌측을 차량내측이라고 보면, 제2러버(32)에는 도 5와 같이 호형의 완충구멍(35)이 차량내측으로 뚫려 있다.The first rubber 31 and the second rubber 32 are completely separated as shown in FIG. 4 when viewed in the direction A of FIG. 3, and the spaced apart intervals have a distance of δ as shown in FIG. 3. . In addition, as shown in FIG. 3, when the right side is viewed as the outside of the vehicle, and the left side is regarded as the inside of the vehicle, the second rubber 32 has an arc-shaped buffer hole 35 as shown in FIG. 5.
이 완충구멍(35)의 간격은 도 3에서 표시하는 바와 같이 δ'의 간격을 이루고 있다. 그런데, 상기한 제1러버(31)와 제2러버(32)의 간격인 δ와 제2러버(32)의 완충구멍(35)의 간격인 δ'는 동일(δ=δ')하다.As shown in Fig. 3, the gap between the buffer holes 35 is a gap of? '. By the way, δ which is the distance between the first rubber 31 and the second rubber 32 and δ 'which is the distance between the buffer holes 35 of the second rubber 32 are the same (δ = δ').
본 고안은 상기와 같은 구성에 따라, 도 3에서 보는 바와 같이 차량외측으로 부터 로워 암(36)에 의하여 P방향으로 외력이 입력될 때에는 δ=δ'이므로 δ간격만큼 찌그러지면서 충격을 흡수한다.According to the configuration as described above, when the external force is input in the P direction by the lower arm 36 from the outside of the vehicle as shown in FIG. 3, since δ = δ ', the shock is absorbed by the δ interval.
그리고, 로워 암의 스윙 모션(swing motion)에 의하여 주어지는 스트로크만큼의 Q방향의 힘(굽힘모멘트)이 로워 암 리어 수직 부싱에 작용할 때에는 제1러버(31)와 제2러버(32)의 간격 δ사이에서 신장과 수축이 일어나므로 그 특성에 따라 굽힘모멘트를 흡수하게 되는 것이다.Then, when the force in the Q direction (bending moment) equal to the stroke given by the swing motion of the lower arm acts on the lower arm rear vertical bushing, the distance δ between the first rubber 31 and the second rubber 32 Elongation and contraction occurs between the absorption of the bending moment according to its characteristics.
이와 같은 본 고안은 러버를 2피스(piece)로 분할하여 측면 충격과 굽힘모멘트에 대한 충격흡수를 충실히 수행할 수 있어서 로워 암 리어 수직 부싱의 특성을 좋게하고, 이에 따라 승차감이 향상되는 효과가 있다.This invention can divide the rubber into two pieces (piece) to faithfully perform the impact shock on the side impact and bending moment to improve the characteristics of the lower arm vertical bushing, thereby improving the ride comfort .
