본 발명은 커플드 토션빔 액슬 서스펜션용 마운팅부시와 차체의 연결구조에 관한 것으로서, 더욱 더 상세하게는 차량을 운행중 회전을 수행시 마운팅부시가 좌우로 유동하는 경우에도 상기 마운팅부시가 차체 장착부의 내측면과 접하여 간섭이 발생하지 않도록 함과 동시에 탄성스프링의 자체 복원력에 의해 차량의 후부에 흔들림 현상이 발생하지 않아 차량의 주행안정성이 향상되도록 하는 커플드 토션빔 액슬 서스펜션용 부시와 차체의 연결구조에 관한 것이다.The present invention relates to a connection structure between a mounting bush for a coupled torsion beam axle suspension and a vehicle body, and more particularly, even when the mounting bush flows from side to side when performing a rotation while driving a vehicle, the mounting bush is in the vehicle body mounting portion. The coupling structure between the coupler torsion beam axle suspension and the vehicle body which improves the driving stability of the vehicle by preventing the rear side of the vehicle due to the self-resilience of the elastic spring. It is about.

서스펜션(suspesion)은 차축과 차체를 연결하여 주행 중에 차축이 노면으로부터 받는 진동이나 충격을 차체에 직접 전달하지 않도록 하여, 차체의 손상을 방지하고 차량의 승차감과 안정성을 확보하기 위한 장치이다.Suspension is a device that connects the axle and the body so as not to directly transmit vibrations or shocks received from the road surface to the vehicle body while driving, thereby preventing damage to the vehicle body and ensuring ride comfort and stability of the vehicle.

한편, 차량의 후륜 서스펜션에 이용되는 토션빔 액슬 서스펜션은 리어 서스펜션의 한 타입으로 독립현가장치(맥퍼슨, 더블위시본 등)와는 달리 좌, 우륜이 상호 작용되는 서스펜션 타입으로서, 서로 역방향으로 스트로크 시 트레일링아암과 토션빔이 서로 간섭하여 상호 비틀리게 된다.On the other hand, the torsion beam axle suspension used for the rear wheel suspension of the vehicle is a type of rear suspension, which is a suspension type in which the left and right wheels interact with each other, unlike independent suspension devices such as McPherson and Double Wishbone. The ring arm and torsion beam interfere with each other and twist each other.

이때, 서스펜션 전체가 플렉시블 바디(Flexible Body)로 작용하게되고, 이 비틀림 힘에 의해 서스펜션이 결정되어지고, 토션빔 및 트레일링아암의 위치, 형상등으로 롤강성, 횡강성, 캠버의 변화가 조절되어진다.At this time, the whole suspension acts as a flexible body, the suspension is determined by this torsional force, and the roll stiffness, lateral stiffness, and change of camber are controlled by the position and shape of the torsion beam and the trailing arm. It is done.

한편, 이러한 커플드 토션빔 액슬(coupled torsion beam axie) 서스펜션은 차체 장착부에 설치되는 마운팅부시가 후부에 압입되어 있는 한쌍의 트레일링아암과, 상기 트레일링아암과 트레일링아암에 일측 및 타측단부가 각각 용착되는 토션 빔과, 상기 토션빔과 트레일링아암 사이에 후부가 접하며 용착되는 스프링시트에 안착이 이루어지는 코일스프링과, 상기 스프링시트의 일측부가 용착되어 있는 트레일링아암의 상부 일측에 하부가 용착되는 스핀들브라켓으로 구성되어 있다.On the other hand, such a coupled torsion beam axle suspension has a pair of trailing arms in which a mounting bush installed in the vehicle body mounting portion is press-fitted to the rear, and one side and the other end of the trailing arm and the trailing arm. The lower part is welded to the upper side of the torsion beam which is welded to each other, the coil spring which is seated on the spring seat welded to the rear part between the torsion beam and the trailing arm, and the one side of the spring seat is welded. It consists of a spindle bracket.

이러한 자동차의 커플드 토션빔 액슬 서스펜션은 토션빔과 트레일링아암 사이에 후부가 접하며 용착되는 스프링시트에 코일스프링이 지지되도록 설치되고, 상기 트레일링아암의 후부에 압입되어 있는 마운팅부시는 차체 장착부에 볼트 너트 체결되며, 상기 마운팅부시가 차체 장착부에 볼트 너트 체결되어 있는 트레일링아암의 상부 일측에 용착된 스핀들브라켓에는 휠이 연결 설치되어, 차량을 운행시 노면으로부터 타이어의 상부로 가해지는 힘이 스핀들브라켓을 통해 트레일링아암 및 차체에 볼트 너트 체결되어진 마운팅부시로 유입되면서 흡수가 이루어지게 되고, 코일스프링을 통해 스프링시트로 전달되는 차량을 누르는힘은 토션빔과 트레일링아암 및 차체에 볼트 너트 체결되어진 마운팅부시로 전달되면서 흡수가 이루어지게 된다.Coupled torsion beam axle suspension of such a vehicle is installed so that the coil spring is supported on the spring seat is welded to the rear contact between the torsion beam and the trailing arm, the mounting bush is press-fitted to the rear of the trailing arm The bolt is fastened to the spindle bracket on which the mounting bush is welded on the upper side of the trailing arm where the mounting bush is bolted to the vehicle body mounting portion. A wheel is connected to the spindle bracket. The bracket is absorbed into the mounting bush which is bolted to the trailing arm and the vehicle body through the bracket, and absorbed. The pressing force of the vehicle transmitted to the spring seat through the coil spring is fastened to the torsion beam, the trailing arm and the vehicle body. Absorption takes place as it is delivered to the mounting bush.

그러나 이러한 커플드 토션빔 액슬(coupled torsion beam axie) 서스펜션용 마운팅부시(100)는 도 1에 도시하고 있는 바와 같이, 차체 장착부(200)에 삽입된 상태에서 차체 장착부(200) 외측에 용착된 너트(400)에 체결이 이루어지도록 차체 장착부(200)와 마운팅부시(100)를 관통하는 볼트(300)에 의해서만, 상기 차체 장착부(200)에 마운팅부시(100)가 설치된 상태를 유지하게 됨으로써, 차량을 운행 중 선회등을 수행 시 마운팅부시(100)가 선회하는 방향으로 유동되면서 크랙이 발생하게 됨은 물론, 차량의 후부에 흔들림현상이 발생하여 주행안정성을 해치게 되는 문 제점이 있었다.However, as shown in FIG. 1, the coupled torsion beam axle suspension bushing 100 is a nut welded to the outside of the vehicle mounting unit 200 in a state of being inserted into the vehicle mounting unit 200. Only by the bolts 300 passing through the vehicle body mounting unit 200 and the mounting bush 100 so as to be fastened to the 400, the vehicle mounting unit 100 maintains a state in which the mounting bush 100 is installed. During the operation, the mounting bush 100 flows in the turning direction while performing the turning, so that cracks may occur, as well as the rear side of the vehicle, causing a problem that impairs the driving stability.

따라서 종래에도 상기와 같은 문제점을 해결하기 위해 마운팅부시의 좌우 양측에 철재 스토퍼를 장착시켜, 차량을 운행중 선회등을 수행시에도 마운팅부시에 크랙등이 발생하여 파손되는 것이 억제되도록 하고 있다.Therefore, conventionally, in order to solve the above problems, the steel stoppers are mounted on both sides of the mounting bush so as to prevent the cracks from occurring in the mounting bush even when the vehicle is turning while driving.

그러나 상기와 같이 마운팅부시의 좌우 양측에 철재 스토퍼를 장착시키는 경우에는 마운팅부시의 좌우 양측에 각각 장착되어 있는 철재 스토퍼가 차량을 운행중 선회등을 수행 시, 차체 장착부의 내측면과 접촉되면서 소음이 발생하게 되는 문제점이 있었다.However, when the steel stoppers are mounted on both the left and right sides of the mounting bush as described above, when the steel stoppers mounted on the left and right sides of the mounting bush are turning while driving the vehicle, noise is generated when the steel stopper comes into contact with the inner surface of the vehicle mounting unit. There was a problem.

본 발명의 목적은 상기 종래와 같은 문제점을 해결 하기 위해 안출된 것으로서, 마운팅부시의 좌우 양측에 장착된 철재 스토퍼와 차체 장착부의 내측면 사이에 탄성스프링을 설치하여, 상기 마운팅부시가 차량을 운행중 선회등을 수행하는 것에 의해 차량이 선회하는 방향으로 유동이 발생하는 경우에도 철재 스토퍼와 차체 장착부의 내측면 사이에 설치된 탄성스프링의 자체 탄성력에 의해 마운팅부시의 복원성이 좋아져 차량의 후부에 흔들림 현상이 발생하지 않도록 하면서도, 상기 철재 스토퍼와 차체 장착부 내측면 사이에 간섭이 발생하면서 각종 소음이 발생되는 것이 미연에 방지되도록 하는 커플드 토션빔 액슬 서스펜션용 마운팅부시와 차체의 연결구조를 제공하는 데 있다.An object of the present invention is to solve the problems as described above, by installing an elastic spring between the steel stopper mounted on the left and right sides of the mounting bush and the inner surface of the vehicle body mounting portion, the mounting bush is turning while driving the vehicle. Even if a flow occurs in a direction in which the vehicle is turning by performing a back or the like, the resilience of the mounting bush is improved by the self-elastic force of the elastic spring installed between the steel stopper and the inner surface of the vehicle body mounting portion, and the rear side of the vehicle shakes. The present invention provides a connection structure between the mounting bush and the coupled torsion beam axle suspension for preventing various noises from occurring while interference between the steel stopper and the inner surface of the vehicle mounting portion is prevented.

이러한 본 발명의 목적은, 트레일링아암(T)의 후부에 압입되어 있는 마운팅부시(100)가 차체 장착부(200)에 인입되고, 상기 차체 장착부(200)와 마운팅부시(100)를 관통하는 볼트(300)가 차체 장착부(200)의 외측면에 용착된 너트(400)에 체결되는 것에 있어서, 상기 마운팅부시(100)의 좌우 양측에 각각의 철재 스토퍼(500)가 장착되고, 상기 철재 스토퍼(500)와 차체 장착부(200)의 내측면 사이에 탄성스프링(600)이 설치되는 것에 의해 달성된다.The object of the present invention is that the mounting bush 100 press-fitted to the rear of the trailing arm (T) is introduced into the vehicle body mounting portion 200, the bolt passing through the vehicle body mounting portion 200 and the mounting bush (100) When the 300 is fastened to the nut 400 welded to the outer surface of the vehicle body mounting unit 200, the respective steel stoppers 500 are mounted on both left and right sides of the mounting bush 100, and the steel stoppers ( It is achieved by the elastic spring 600 is installed between the 500 and the inner surface of the vehicle body mounting portion 200.
