Description

자동차의 현가장치용 암 부시와 크로스멤버의 체결구조Fastening structure of arm bush and cross member for vehicle suspension

본 고안은 자동차에 관한 것으로서, 보다 상세하게는, 차체의 하중이 고려된 비틀림각에 따라 암 부시를 크로스멤버에 체결하기가 용이한 자동차의 현가장치용 암 부시와 크로스멤버의 체결구조에 관한 것이다.The present invention relates to a vehicle, and more particularly, to a fastening structure of the arm bush and the cross member for the suspension device of the vehicle that is easy to fasten the arm bush to the cross member according to the torsion angle considering the load of the vehicle body. .

일반적으로, 자동차는 차축과 차체를 연결하여 주행할 때 노면에서 받는 진동이나 충격이 차체에 직접 전달되지 않도록 현가장치를 설치함으로써, 차체나 하물의 손상을 방지하고, 승차감의 향상을 도모하였다.BACKGROUND ART In general, automobiles are provided with suspension systems so that vibrations or shocks received from the road surface are not directly transmitted to the vehicle body when the vehicle is connected by connecting the axle and the vehicle body, thereby preventing damage to the vehicle body or loads, and improving ride comfort.

현가장치 중 자동차의 전단에 설치되는 전방현가장치는, 도 1 에 도시된 바와 같이, 노면에서 받는 충격을 완화하는 코일스프링(10)과, 코일스프링(10)의 자유진동을 억제하여 승차감을 향상시키는 쇽업소버(20), 하부차체의 강도 및 강성을 증진시키는 크로스멤버(30)와, 휠의움직임을 조절하도록 된 현가암(40) 및 자동차가 좌우로 요동하는 것을 방지하는 스테빌라이저(50)로 구성된다.As shown in FIG. 1, the front suspension device installed at the front of the vehicle among the suspension devices improves the riding comfort by suppressing the free vibration of the coil spring 10 and the coil spring 10 to alleviate the shock received from the road surface. The shock absorber 20, the cross member 30 to enhance the strength and rigidity of the lower body, the suspension arm 40 to adjust the movement of the wheel and the stabilizer 50 to prevent the vehicle from rocking from side to side It consists of.

여기서, 현가암(40)은 암 부시(60)를 매개로 하여 크로스멤버(30)에 회동가능하도록 체결되는 구조로 되어 있는 데, 암 부시(60)는 노면에서 받는 충격이나 진동이 현가암(40)을 통해 크로스멤버(30)에 직접 전달되지 않도록 이를 완화 및 흡수하는 작용을 한다.Here, the suspension arm 40 has a structure that is fastened to the cross member 30 so as to be rotatable through the arm bush 60, the arm bush 60 is a suspension arm (shock or vibration received from the road surface) 40) acts to alleviate and absorb it so as not to be directly transmitted to the crossmember (30).

이와 같은 작용을 하는 암 부시(60)는, 도 2 및 도 3 에 도시된 바와 같이 현가암(40)과 체결되는 외측파이프(Outer Pipe)(61)와, 크로스멤버(30)와 체결되는 내측파이프(Inner Pipe)(62)로 구성되어 지며, 외측파이프(61)와 내측파이프(62)의 사이에는 고무부재(63)가 내설된 구조로 이루어진다.As shown in FIGS. 2 and 3, the arm bush 60 having such a function includes an outer pipe 61 fastened to the suspension arm 40 and an inner side fastened to the cross member 30. It consists of a pipe (Inner Pipe) 62, the rubber member 63 is formed between the outer pipe 61 and the inner pipe 62 has a structure built.

한편, 상기 암 부시(60)가 현가암(40)에서 전해지는 충격 및 진동을 완화 및 흡수할 수 있는 것은, 임피던스(Impedance)의 미스매칭(Mismatching)에 의한 진동감쇠효과 때문인데, 이것은 서로 다른 임피던스의 두 물체가 상호 연결되어 있는 상태에서, 어느 한쪽의 물체에서 발생된 진동이 다른쪽 물체에 전달될 경우 이 진동은 임피던스의 차이에 의해 진행방향이 바뀌거나 그 일부만 전달되는 현상을 이용한 것으로, 임피던스의 차이가 클수록 진동감쇠효과가 더욱 크게 나타난다는 것이다.On the other hand, the arm bush 60 is able to mitigate and absorb the shock and vibration transmitted from the suspension arm 40, due to the vibration damping effect due to mismatching of the impedance (Impedance), which is different When two objects of impedance are connected to each other, when the vibration generated from one object is transmitted to the other object, the vibration is used to change the direction of propagation or only a part thereof due to the difference in impedance. The greater the difference in impedance, the greater the damping effect.

즉, 외측파이프(61) 및 내측파이프(62)를 구성하는 철재의 임피던스는, 고무부재(63)를 구성하는 고무재질의 임피던스보다 크게되는데, 이와 같을 경우, 현가암(40)으로부터 외측파이프(61)에 전해지는 충격이나 진동의 전달방향이 바뀌어지거나, 그 일부만이 내측파이프(62)를 통해 크로스멤버(30)에 전달됨으로써, 노면으로부터 현가암(40)을 통해 크로스멤버(30)에 전달되는 충격이나 진동이 완화 및 흡수되는 것이다.That is, the impedance of the steel constituting the outer pipe 61 and the inner pipe 62 is larger than the impedance of the rubber material constituting the rubber member 63. In this case, the outer pipe (from the suspension arm 40) The transmission direction of the shock or vibration transmitted to the 61 is changed, or only a part thereof is transmitted to the cross member 30 through the inner pipe 62, and thus is transmitted from the road surface to the cross member 30 through the suspension arm 40. The shocks or vibrations that are caused are alleviated and absorbed.

한편, 상기 현가암(40)은 차체의 하중에 따른 크로스멤버(30)와 체결되는 위치를 중심으로 하여 휠과 체결되는 쪽의 종단이 상하방향으로 변위되는데, 이와 같게 되면, 현가암(40)에 체결된 암 부시(60)의 외측파이프(61)가 원축으로 중심으로 하여 시계 또는 반시계방향으로 회동하게 되고, 이로 인하여 고무부재(63)가 비틀리게 된다.On the other hand, the suspension arm 40 is the end of the side is fastened to the wheel with respect to the position of the cross member 30 in accordance with the load of the vehicle body is displaced in the vertical direction, if so, the suspension arm 40 The outer pipe 61 of the arm bush 60 fastened to the center shaft rotates in a clockwise or counterclockwise direction with a central axis, thereby causing the rubber member 63 to be twisted.

상기한 바와 같이, 고무부재(63)가 비틀리게 되면, 내부재질의 밀도가 높아져서 임피던스가 커지기 때문에, 외측파이프(61) 및 내측파이프(62)의 임피던스와의 차이가 작아지게 되어, 암 부시(60)의 충격 및 진동에 대한 감쇠성능이 상대적으로 저하된다.As described above, when the rubber member 63 is twisted, since the density of the inner material is increased and the impedance is increased, the difference between the impedances of the outer pipe 61 and the inner pipe 62 becomes small, and the female bush ( The damping performance of the shock and vibration of 60) is relatively lowered.

따라서, 보다 좋은 승차감을 유지하기 위해서는, 암 부시(60)를 크로스멤버(30)에 체결할 때, 현가암(40)에 가장 일반적인 차체의 하중이 실린 상태에서, 암 부시(60)의 고무부재(63)가 비틀리지 않도록 체결하는 것이 바람직하다.Therefore, in order to maintain a better ride comfort, when the arm bush 60 is fastened to the cross member 30, the rubber member of the arm bush 60 in a state where the load of the most common vehicle body is loaded on the suspension arm 40. It is preferable to fasten so that 63 may not twist.

한편, 차체의 하중에는, 공차하중과, 설계하중 및, 적차하중이 있는 데, 상기 공차하중은, 승객이 자동차에 승차하지 않은 차체의 하중이고, 상기 설계하중은, 상기 공차하중에 2인의 승차인원에 대한 하중을 합산한 하중이며, 상기 적차하중은, 최대승차인원이 전원승차한 상태의 차체에 대한 하중이다.On the other hand, the load of the vehicle body includes a tolerance load, a design load, and a loading load, wherein the tolerance load is a load of a vehicle body in which a passenger does not ride in an automobile, and the design load is a ride of two persons in the tolerance load. It is the load which added the load to the personnel, and the said loading load is the load with respect to the vehicle body in which the maximum occupant occupied the power supply.

여기서, 가장 일반적인 차에의 하중은 상기 설계하중이기 때문에, 현가암(40)에이 설계하중이 실린 상태에서, 암 부시(60)의 고무부재(63)가 비틀리지 않도록 체결하는 것이 바람직한 것이다.Here, since the most common load on the vehicle is the design load, it is preferable that the rubber member 63 of the arm bush 60 is fastened so that the suspension arm 40 is loaded with the design load.

다른 한편, 종래의 암 부시(60)와 크로스멤버(30)는, 도 4 및 도 5 에 도시된 바와 같이, 암 부시(60)의 내측파이프(62)가 마운팅브라켓(31)에 의해 지지 및 고착되어, 크로스멤버(30)에 체결되는 구조로 되어 있었다.On the other hand, the conventional arm bush 60 and the cross member 30, as shown in Figures 4 and 5, the inner pipe 62 of the arm bush 60 is supported by the mounting bracket 31 and It was fixed and had a structure fastened to the cross member 30.

상기 암 부시(60)와 크로스멤버(30)는, 통상적으로, 차체가 들어 올려진 리바운드(Rebound)상태 즉, 현가암(40)에 차체의 하중이 실리지 않은 상태에서, 체결작업이 이루어지게 되는 데, 이 때, 암 부시(60)를 비틀림각 0의 상태로 크로스멤버(30)에 체결하게 되면, 도 6 에 도시된 바와 같이, 상기 설계하중이 현가암(40)에 실리게 될 때, 암 부시(60)에 비틀림각이 발생되어, 이 암 부시(60)에 내재한 고무부재(63)가 비틀리게 된다.The arm bush 60 and the cross member 30 are typically fastened in a rebound state in which the vehicle body is lifted, that is, in a state in which the load of the vehicle body is not loaded on the suspension arm 40. At this time, when the arm bush 60 is fastened to the cross member 30 in the state of the torsion angle 0, as shown in Figure 6, when the design load is loaded on the suspension arm 40, The twist angle is generated in the arm bush 60, and the rubber member 63 inherent in the arm bush 60 is twisted.

이를 방지하기 위해서는, 암 부시(60)의 내측파이프(62)를 차체의 하중이 고려된 소정의 비틀림각에 따라 마운팅브라켓(31)에 고착시켜서 크로스멤버(30)에 체결하여야 하는 데, 자동차의 실제 조립공정에서는, 암 부시(60)를 차체의 하중이 고려된 비틀림각에 따라 정확하게 마운팅브라켓(31)에 고착시키기가 용이하지 못하였고, 이에 따라 조립과정이 복잡해져서 작업성이 저하되는 문제점이 있었다.In order to prevent this, the inner pipe 62 of the arm bush 60 should be fixed to the mounting bracket 31 according to a predetermined torsion angle considering the load of the vehicle body and fastened to the cross member 30. In the actual assembling process, it was not easy to fix the arm bush 60 to the mounting bracket 31 correctly according to the torsion angle in consideration of the load of the vehicle body. there was.

따라서, 본 고안은 상기한 바와 같은 문제점을 해결하기 위한 것으로서, 본 고안은, 암 부시와 크로스멤버에 대한 체결작업을 단순화하여, 자동차의 조립공정에 대한 작업성을 향상시킬 수 있는 자동차의 현가장치용 암 부시와 크로스멤버의 체결구조를 제공하는 데에 그 목적이 있다.Accordingly, the present invention is to solve the problems as described above, the present invention, by simplifying the fastening operation for the arm bush and the cross member, the suspension device of the vehicle that can improve the workability for the assembly process of the vehicle The purpose is to provide a fastening structure between the lava bush and the crossmember.

상기 목적을 달성하기 위한 본 고안의 자동차의 현가장치용 암 부시와 크로스멤버의 체결구조는, 휠의 움직임을 상하방향으로 조절하도록 되어 있는 현가암으로부터 전달되는 충격 및 진동을 감쇠시키도록 되어 있는 암 부시 및, 일측면에 상기 암 부시가 원반형태의 보호판을 체결매개로 하여 회동가능하도록 보울팅결합되어 있고 크로스멤버로 구성되는 것을 특징으로 한다.The fastening structure of the arm bush for the vehicle suspension device and the cross member of the present invention for achieving the above object, the arm is designed to attenuate the shock and vibration transmitted from the suspension arm to adjust the wheel movement in the vertical direction The bush and one side of the arm bush is characterized in that the bowl is coupled to the rotating so as to be rotatable by the disk-shaped protection plate as a fastening medium, characterized in that consisting of cross members.
