본 발명은 차량의 서스펜션 구조에 관한 것으로서, 보다 상세하게는 상용차량의 차축을 지지하는 로워시트에 관련된 기술에 관한 것이다.The present invention relates to a suspension structure of a vehicle, and more particularly, to a technique related to a lower seat supporting an axle of a commercial vehicle.

종래에 상용차량의 서스펜션에 사용되는 로워시트는 리프스프링을 사용한 서스펜션에서 리프스프링의 상측을 차축에 고정시킬 때 원하는 각도의 평면부위를 제공하는 역할을 하거나, 에어스프링을 사용하는 서스펜션에서 서포트빔의 상측을 차 축에 고정시킬 때 필요한 각도의 평면부위를 제공하는 역할을 하는 데에만 사용되고 있다.The lower seat used in the suspension of a commercial vehicle conventionally serves to provide a planar portion at an angle when the upper side of the leaf spring is fixed to the axle in the suspension using the leaf spring, or the support beam of the suspension using the air spring. It is only used to provide a planar portion of the angle required when fixing the upper side to the axle shaft.

따라서, 상기한 바와 같은 로워시트를 사용하는 서스펜션의 구조에서는 상기 로워시트와 짝을 이루어 차축의 상측에 결합되는 어퍼시트와 함께 볼트로 조여짐에 의해 차축과 리프스프링 또는 에어스프링이 연결되는 구조를 가지고 있다.Accordingly, in the structure of the suspension using the lower seat as described above, a structure in which the axle and the leaf spring or the air spring are connected by being bolted together with the upper seat coupled to the upper seat in pair with the lower seat is coupled with the upper seat. Have.

아울러, 상기한 바와 같은 서스펜션에 장착되는 스태빌라이저바는 별도의 브라켓을 이용하여 서포트빔 또는 리프스프링의 하단에 마운팅하도록 되어 있다.In addition, the stabilizer bar mounted on the suspension as described above is to be mounted to the lower end of the support beam or leaf spring using a separate bracket.

따라서, 상기 로워시트와, 어퍼시트 및 스태빌라이저바를 마운팅하기 위한 마운팅브라켓 등 다수의 부품이 소요되며, 스태빌라이저바의 마운팅 위치가 차축으로부터 멀리 떨어질 수 밖에 없는 구조이어서, 롤의 발생시에, 차축의 움직임의 스태빌라이저바에 충분히 전달되지 못해서, 롤 제어 성능이 떨어지는 경향이 있다. Therefore, a number of parts such as the lower seat, the mounting bracket for mounting the upper seat and the stabilizer bar are required, and the mounting position of the stabilizer bar is inevitably far away from the axle, so that when the roll is generated, the movement of the axle Insufficient transmission to the stabilizer bar tends to degrade roll control performance.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 차축과 서포트빔 또는 리프스프링과의 결합 및 스태빌라이저바의 장착에 소요되는 부품의 수를 최소화하여, 부품수 저감 및 중량 저감의 효과를 얻음과 아울러, 롤의 발생시 차축의 움직임이 스태빌라이저바에 보다 충분한 상태로 전달될 수 있도록 하여, 롤 제어 성능을 보다 향상시킬 수 있도록 한 차량의 서스펜션 구조를 제공함에 그 목적이 있다. The present invention has been made to solve the problems described above, by minimizing the number of parts required for the coupling of the axle and the support beam or the leaf spring and the mounting of the stabilizer bar, the effect of reducing the number of parts and weight In addition, the object of the present invention is to provide a suspension structure of a vehicle that allows the movement of the axle to be transmitted to the stabilizer bar in a sufficient state when the roll is generated, thereby further improving roll control performance.

상기한 바와 같은 목적을 달성하기 위한 본 발명 차량의 서스펜션 구조는, 차축의 하측면과 용접될 용접자리면 및 관통되는 볼트와 체결되는 너트가 압착될 너트자리면을 일체로 구비한 로워시트와; 상기 로워시트에서 차량 길이방향의 일측으로 일체로 돌출되어 형성된 스태빌라이저바연결부와; 상기 스태빌라이저바연결부에 몸통부가 회동 가능하게 연결된 스태빌라이저바;를 포함하여 구성된 것을 특징으로 한다.Suspension structure of the present invention for achieving the object as described above, the lower seat of the axle and the welding seat surface to be welded and the lower seat having a nut seat surface to which the nut is fastened to the nut is fastened with the bolt; A stabilizer bar connection part protruding integrally from the lower seat to one side of the vehicle longitudinal direction; And a stabilizer bar to which the body portion is rotatably connected to the stabilizer bar connecting portion.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1과 도 2를 참조하면, 본 발명 실시예는 차축(1)의 하측면과 용접될 용접자리면(3)을 구비하고, 관통되는 볼트와 체결되는 너트(5)가 압착될 너트자리면(7)을 일체로 구비하며, 차량 길이방향 일측으로 일체로 돌출되어 형성된 스태빌라이저바연결부(9)를 일체로 구비한 로워시트(11)와; 상기 스태빌라이저바연결부(9)에 몸통부가 회동 가능하게 연결된 스태빌라이저바(13)를 포함하여 구성되어 있다.1 and 2, an embodiment of the present invention includes a welding seat surface 3 to be welded to the lower side of the axle 1, and a nut seat surface to which the nut 5 coupled to the bolt to be penetrated is pressed. A lower seat (11) integrally provided with a stabilizer bar connecting portion (9) formed integrally with one side and protruding integrally with one side of the vehicle longitudinal direction; The stabilizer bar connecting portion 9 is configured to include a stabilizer bar 13 connected to the body portion rotatably.

즉, 종래에 상기 로워시트(11)와 함께 서스펜션을 구성하였던 어퍼시트 및 스태빌라이저 마운팅브라켓을 제거하고, 상기 로워시트(11)가 이들의 기능을 한꺼번에 수행할 수 있도록 한 것이다.That is, the upper seat and the stabilizer mounting bracket, which have been conventionally configured with the lower seat 11, are removed, and the lower seat 11 can perform these functions at once.

상기 로워시트(11)의 용접자리면(3) 상측에는 차축(1)이 용접에 의해 결합되고, 상기 너트자리면(7)에는 상기 로워시트(11)를 리프스프링 또는 서포트빔에 고정시키는 볼트와 체결되는 너트(5)가 압착되어 로워시트(11)를 리프스프링 또는 서포트빔에 일체로 고정시키게 된다.The axle 1 is coupled to the upper surface of the seat seat 3 of the lower seat 11 by welding, and the bolt seat 7 fixes the lower seat 11 to the leaf spring or the support beam. The nut 5 is fastened to the lower seat 11 to be integrally fixed to the leaf spring or the support beam.

즉, 종래에는 어퍼시트에 형성되었던 너트자리면(7)을 로워시트(11)에 일체로 구비하고, 어퍼시트를 배제시킨 것이다.That is, the nut seat surface 7 which was conventionally formed in the upper seat is provided integrally in the lower seat 11, and the upper seat is excluded.

또한, 종래의 스태빌라이저바 마운팅브라켓도 제거하고, 스태빌라이저바(13)의 몸통부가 상기 로워시트(11)에 일체로 형성된 스태빌라이저바연결부(9)에 고정되도록 하고 있다.In addition, the conventional stabilizer bar mounting bracket is also removed, and the body of the stabilizer bar 13 is fixed to the stabilizer bar connecting portion 9 formed integrally with the lower seat 11.

따라서, 상기와 같이 로워시트(11)만으로, 종래의 어퍼시트와 스태빌라이저바 마운팅브라켓이 하던 역할을 모두 수행하고, 이들 부품을 배제시킴으로써, 서스펜션을 구성하는 부품수를 저감시키고, 차량의 중량을 저감시키는 효과를 얻게 된다.Therefore, as described above, the lower seat 11 alone performs all of the roles of the conventional upper seat and the stabilizer bar mounting bracket and excludes these parts, thereby reducing the number of parts constituting the suspension and reducing the weight of the vehicle. You will get the effect.

한편, 여기서 상기 스태빌라이저바(13)는 차량의 횡방향으로 길게 형성되는 중간부분을 몸통부로 하고, 상기 몸통부의 양단에 차량의 길이방향으로 휘어진 끝부분을 아암부로 칭하고 있다.On the other hand, the stabilizer bar 13, the middle portion formed in the transverse direction of the vehicle as the body portion, and the end portion that is bent in the longitudinal direction of the vehicle on both ends of the body portion is called the arm portion.

상기 스태빌라이저바(13)의 아암부는 도 2에 도시된 것처럼, 스태빌라이저링크(15)를 매개로 차체(17)에 연결되는 구조이다.As shown in FIG. 2, the arm part of the stabilizer bar 13 is connected to the vehicle body 17 via the stabilizer link 15.

즉, 스태빌라이저바의 일반적인 연결구조는 스태빌라이저바의 몸통부가 차체에 고정되고, 아암부가 차축 쪽에 연결되는 것이지만, 본 발명에서는 그 반대로 몸통부가 차축(1) 쪽에 고정되고, 아암부는 차체(17) 쪽에 연결되는 구조를 취한 것이다.That is, the general structure of the stabilizer bar is that the body of the stabilizer bar is fixed to the body, the arm is connected to the axle side, in the present invention, on the contrary, the body is fixed to the axle (1) side, the arm is connected to the body 17 side It takes a structure that becomes.

더구나, 상기 스태빌라이저바(13)의 몸통부는 상기 로워시트(11)와 일체로 형성된 스태빌라이저바연결부(9)에 고정되므로, 차축(1)과 인접한 위치에서, 차축(1)의 거동을 직접적으로 전달받게 되므로, 스태빌라이저바(13)에 차축의 롤 변위가 보다 효과적으로 전달되게 되어, 차량의 롤 제어 성능이 더욱 향상되게 된다.Moreover, the body portion of the stabilizer bar 13 is fixed to the stabilizer bar connecting portion 9 formed integrally with the lower seat 11, so that the position of the stabilizer bar 13 is directly adjacent to the axle 1, thereby directly transmitting the behavior of the axle 1. Since the roll displacement of the axle is more effectively transmitted to the stabilizer bar 13, the roll control performance of the vehicle is further improved.

이상과 같이 본 발명에 의하면, 차축과 서포트빔 또는 리프스프링과의 결합 및 스태빌라이저바의 장착에 소요되는 부품의 수를 최소화하여, 부품수 저감 및 중량 저감의 효과를 얻음과 아울러, 롤의 발생시 차축의 움직임이 스태빌라이저바에 보다 충분한 상태로 전달될 수 있도록 하여, 롤 제어 성능을 보다 향상시킬 수 있도록 한다. According to the present invention as described above, by minimizing the number of parts required for the coupling between the axle and the support beam or the leaf spring and the mounting of the stabilizer bar, the effect of reducing the number of parts and weight is reduced, and the axle when the roll is generated By allowing the movement of the to be transmitted to the stabilizer bar in a more sufficient state, it is possible to further improve the roll control performance.
