일반적인 차량용 에어 서스펜션은 도 1에서와 같이, 프레임과 리어 액슬 사이에 설치되어 차체의 무게를 지지하고 노면으로부터의 진동과 충격을 흡수하는 에어 스프링(100)을 갖는다. 이때 상기 에어 스프링(100)에서 발생하는 스프링 작용은 스테빌라이져(102)에 의해 흡수된다. 또한 레벨링 밸브(104)에 의해 에어 스프링(100)의 내압을 조절하며, 차량의 선회 및 제동시에 발생되는 힘을 지지하기 위하여 레이디어스 로드(104)를 장착한다.A typical vehicle air suspension has an air spring 100 installed between the frame and the rear axle to support the weight of the vehicle body and absorb vibrations and shocks from the road surface, as shown in FIG. 1. At this time, the spring action generated in the air spring 100 is absorbed by the stabilizer 102. In addition, the internal pressure of the air spring 100 is adjusted by the leveling valve 104, and the radial rod 104 is mounted to support the force generated during the turning and braking of the vehicle.

상기 레이디어스 로드(104)의 구조는 도 2에서 보다 상세하게 설명한다.The structure of the radial rod 104 will be described in more detail with reference to FIG. 2.

레이디어스 로드(104)는 부싱 삽입부(106)와 파이프(108)로 이루어지며, 그부싱 삽입부(106)와 파이프(108) 사이의 결합 강도를 강화하기 위하여 도 2 (b)의 A부분에 열박음 용접을 실시하도록 한다.The radial rod 104 is comprised of a bushing insert 106 and a pipe 108, and part A of FIG. 2 (b) to strengthen the bond strength between the bushing insert 106 and the pipe 108. Shrink welding is to be done.

그러나 도 2에서와 같이 종래의 레이디어스 로드는 부싱 삽입부와 파이프를 가공한 후에 열박음 용접을 실시하고 있으므로, 용접 발생시에 길이 오차가 발생되므로, 이에 따른 제작원가가 증대 및 주행 불안정의 문제점이 있었다.However, as shown in FIG. 2, since the conventional radial rod is subjected to shrinkage welding after the bushing insert and the pipe are machined, a length error occurs when welding occurs, thereby increasing manufacturing cost and driving instability. there was.

본 발명의 목적은 부품 제작시 발생되는 길이 오차를 최소화하여 제작 원가를 저감시키고, 또한 주행 성능을 향상시킬 수 있는 차량용 레이디어스 로드를 제공하는데 있다.An object of the present invention is to provide a vehicle radial load that can reduce the manufacturing cost by minimizing the length error generated during manufacturing parts, and also improve the running performance.

또한 상기와 같은 목적을 달성하기 위한 본 발명은 차량용 레이디어스 로드에 있어서, 일측단이 파이프와 용접에 의해 연결되는 연결부와, 상기 연결부와 결합시키기 위한 체결부가 일측단에 형성되고, 외측으로 그 폭이 확개되는 확개부를 갖는 보강부와, 상기 보강부의 확개부 내에 장착되며 내측에 부싱부를 갖는 브라킷부로 이루어지는 것을 특징으로 한다.In addition, the present invention for achieving the above object, in the vehicle radial rod, the one end is connected to the pipe by welding, the coupling part for coupling with the connection is formed at one end, the width of the outside A reinforcement part having this extension part which is extended, and the bracket part which is mounted in the extension part of the said reinforcement part, and has a bushing part in the inside, is characterized by the above-mentioned.

이하 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명한다. 하기 설명 및 첨부 도면과 같은 많은 특정 상세들이 본 발명의 보다 전반적인 이해를 제공하기 위해 나타나 있으나, 이들 특정 상세들은 본 발명의 설명을 위해 예시한 것으로 본 발명이 그들에 한정됨을 의미하는 것은 아니다. 그리고 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. While many specific details, such as the following description and the annexed drawings, are shown to provide a more general understanding of the invention, these specific details are illustrated for the purpose of explanation of the invention and are not meant to limit the invention thereto. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

도 2는 본 발명의 실시예에 따른 차량용 레이디어스 로드를 도시한 도면으로서, 도 2에 따라 본 발명의 구성을 설명한다.FIG. 2 is a diagram illustrating a vehicle radial load according to an embodiment of the present invention, and the configuration of the present invention will be described with reference to FIG. 2.

연결부(1)는 파이프(3)와 용접을 통해 서로 연결되는 구조를 갖는다.이때, 연결부(1)의 일측단에는 파이프(3)와의 용접이 용이하도록 파이프(3)의 내주면에 삽입되도록 체결홈(5)이 형성된다.보강부(7)는 개구된 일단부에 연결부(1)가 삽입되어 체결부(9)를 통해 결합되며, 일단부로부터 연장 형성되어 일단부의 외측으로 일정한 각도를 갖고 그 폭이 확개되는 확개부(11)를 가지며, 확개부(11)에 연장 형성되어 일단부보다 큰 개구가 형성되는 타단부를 갖는다.The connecting portion 1 has a structure in which the pipe 3 is connected to each other by welding. At this time, one end of the connecting portion 1 is inserted into the inner circumferential surface of the pipe 3 so as to facilitate welding with the pipe 3. (5) is formed. The reinforcing portion (7) is connected to the coupling portion (1) is inserted into the open one end through the fastening portion (9), extending from one end is formed at a constant angle to the outside of the one end thereof It has the extension part 11 which width is expanded, and the other end extended in the extension part 11 and the opening larger than one end part is formed.

연결부(1)의 타측단은 보강부(7)의 체결부(9)에 의해 볼트 및 너트로 체결되며, 보강부(7)는 외측으로 폭이 확개되는 확개부(11)를 갖는다.The other end of the connecting portion 1 is fastened with a bolt and a nut by the fastening portion 9 of the reinforcing portion 7, and the reinforcing portion 7 has an extension portion 11 whose width is extended outward.

브라킷부(13)는 보강부(7)의 타단부 내측면에 삽입되어 장착되며 내측에 부싱부(15)가 장착되어 보강부(7)에 결합된다.즉, 확개부(11)의 내에는 브라킷부(13)가 장착되며, 브라킷부(13)의 내측에는 차체와 연결하기 위한 부싱부(15)가 형성되는 구조를 갖는다.The bracket part 13 is inserted into and mounted on the inner side of the other end of the reinforcing part 7 and the bushing part 15 is mounted to the inside of the reinforcing part 7 so as to be coupled to the reinforcing part 7. The bracket portion 13 is mounted, and the inside of the bracket portion 13 has a structure in which a bushing portion 15 for connecting with the vehicle body is formed.

이때, 체결부(9)는 볼트 및 너트로만 한정되는 것이 아니라, 보강부(7)와 연결부(1)를 서로 체결할 수 있는 것이라면 리벳 혹은 그외의 어떤 것이라도 사용하는 것이 가능하다.At this time, the fastening portion 9 is not limited to only bolts and nuts, as long as the reinforcing portion 7 and the connecting portion 1 can be fastened to each other, it is possible to use rivets or anything else.

이와 같이 구성된 레이디어스 로드는 먼저 파이프(3)와 연결부(1)의 체결홈(5)을 용접에 의해 결합시킨 후, 용접 작업에 따른 길이 오차를 측정한다.The radial rod configured as described above first couples the coupling groove 5 of the pipe 3 and the connecting portion 1 by welding, and then measures the length error according to the welding operation.

이러한 용접에 의해 발생된 길이 오차에 따라, 그 길이 오차에 대응할 수 있는 적절한 부위에 보강부(7)의 체결부(9)와 연결부(1)를 결합시킨다.According to the length error generated by this welding, the fastening part 9 and the connection part 1 of the reinforcement part 7 are couple | bonded with the suitable site | part which can correspond to the length error.

또한, 보강부(7)의 확개부(11) 내에는 부싱부(15)를 갖는 브라킷부(13)를 별도로 형성하여, 차량의 제동 및 선회시에 발생되는 힘으로부터 보호할 수 있도록 한다.In addition, a bracket portion 13 having a bushing portion 15 is separately formed in the extension portion 11 of the reinforcement portion 7 so as to protect it from the force generated during braking and turning of the vehicle.

상술한 바와 같이 본 발명에 따른 차량용 레이디어스 로드는 파이프와 연결부의 용접시에 발생되는 길이 오차에 따라 이에 대응하여 보강부를 체결하므로서, 길이 오차에 따른 제작 원가를 저감시키고, 또한 그 길이 오차에 의해 발생될 수 있는 주행 불안정을 크게 저감시켜 주행 안정성을 도모할 수 있는 효과가 있다.As described above, in the vehicle radial load according to the present invention, the reinforcing part is fastened correspondingly according to the length error generated at the time of welding the pipe and the connecting part, thereby reducing the manufacturing cost due to the length error, and also by the length error. There is an effect that can greatly reduce the driving instability that can be generated to improve the driving stability.
