Description

차량 현가장치의 크로스멤버용 부쉬 {BUSH FOR CROSSMEMBER OF SUSPENSION}Bushing for Crossmember of Vehicle Suspension {BUSH FOR CROSSMEMBER OF SUSPENSION}

본 발명은 차량 현가장치의 크로스멤버용 부쉬에 관한 것으로서, 특히 부쉬 제조 후 아우터슬리브에 대한 스웨이징 공정이 불필요한 차량 현가장치의 크로스멤버용 부쉬에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bush for a crossmember of a vehicle suspension, and more particularly to a bush for a crossmember of a vehicle suspension that does not require a swaging process for the outer sleeve after the bush is manufactured.

일반적으로 차량의 현가장치는 타이어와 차체를 연결하여 주행중에 타이어가 노면으로부터 받는 진동이나 충격을 차체에 직접적으로 전달되지 않도록 제어하여 차체와 화물의 손상을 방지하고 승차감을 좋게 만드는 장치로서 노면으로부터 충격을 완화시키는 스프링과, 스프링의 자유진동을 제어하여 승차감을 좋게 하는 쇽업소버 및 차량의 롤링을 방지하는 스태빌라이저바, 차륜의 상하방향운동을 허용하며 횡방향에 대해서는 움직임을 억제하는 콘트롤아암(로어아암, 어퍼아암 및 링크류 등) 및 휠을 회전자유롭게 지지하며 콘트롤아암에 연결된 너클 등으로 구성된다.In general, the suspension system of a vehicle connects the tire and the car body to prevent the tire from being transmitted directly to the car body during vibration while preventing the damage to the car body and cargo and improving ride comfort. Springs to reduce tension, shock absorbers that control the free vibration of the springs to improve ride quality, stabilizer bars that prevent rolling of the vehicle, and control arms that allow vertical movement of the wheels and suppress movement in the lateral direction. , Upper arm and linkage) and wheel freely rotating and consist of knuckle connected to control arm.

여기서 상기 스태빌라이저바는 좌우의 콘트롤암에 양단이 장착되어 좌우의 바퀴가 서로 동시에 상하운동하는 경우에는 작용하지 않지만, 좌우의 바퀴가 서로 상하운동하는 경우에는 비틀려져 그 때에 발생하는 스프링 복원력으로 차체의 롤을 감소시키는 역할을 하고 있다.Here, the stabilizer bar is mounted at both ends of the left and right control arms and does not work when the left and right wheels move up and down at the same time. It serves to reduce the roll.

도 1은 상기와 같은 종래의 스태빌라이저바와 로어아암의 장착구조를 나타내는 사시도(특허 제291058호)이다. 크로스멤버(100)의 양쪽 선단부에 각각 장착된 로어아암(101)의 각 선단부는 너클을 매개로 차륜과 체결되어, 차륜을 적절히 지지해주게 되어 있다.1 is a perspective view (Patent No. 291058) showing a mounting structure of a conventional stabilizer bar and a lower arm as described above. Each front end of the lower arm 101 attached to both front ends of the crossmember 100 is engaged with the wheel via a knuckle to properly support the wheel.

크로스멤버(100)에 대하여 로어아암(101)이 회전운동 또는 미소변위를 허용할 수 있도록 로어암(101)은 부쉬를 매개로 크로스멤버(100)에 장착되어 있다.The lower arm 101 is mounted to the cross member 100 via a bush so that the lower arm 101 can allow rotational movement or micro displacement with respect to the cross member 100.

크로스멤버(100)에는 관통공이 형성되며, 상기 관통공에 삽입되는 볼트를 이용하여 차체에 취부된다.A through hole is formed in the cross member 100 and is mounted to the vehicle body by using a bolt inserted into the through hole.

도2는 종래의 차량 현가장치의 크로스멤버(100)용 부쉬(160)의 구조를 나타내는 단면도이다.2 is a cross-sectional view showing the structure of a bush 160 for a cross member 100 of a conventional vehicle suspension apparatus.

도2에 도시된 바와 같이, 종래 기술의 부쉬(160)는 아우터슬리브(130), 러버(140) 및 인너슬리브(150)로 이루어져 있다.As shown in FIG. 2, the prior art bush 160 includes an outer sleeve 130, a rubber 140, and an inner sleeve 150.

러버(140)는 아우터슬리브(130)의 내면 및 인너슬리브(150)의 외면에 일체가 되도록 가류성형된다.The rubber 140 is vulcanized to be integral with the inner surface of the outer sleeve 130 and the outer surface of the inner sleeve 150.

아우터슬리브(130)는 크로스멤버(100)에 삽입되어 고정되고, 인너슬리브(150)에 볼트(110)를 삽입한 후 너트(112)와 나사결합하여 크로스멤버(100)를 차체(120)에 취부한다.The outer sleeve 130 is inserted into and fixed to the cross member 100, the bolt 110 is inserted into the inner sleeve 150, and then screwed together with the nut 112 to connect the cross member 100 to the vehicle body 120. Mount it.

그런데 상기와 같은 차량 현가장치의 크로스멤버(100)용 부쉬(160)는 다음과 같은 문제점이 있었다.However, the bush 160 for the cross member 100 of the vehicle suspension device as described above has the following problems.

즉, 아우터슬리브(130), 러버(140) 및 인너슬리브(150)를 일체로 형성하는 가류성형 공정이 완료된 후 러버(140)에는 수축이 발생하여 잔류응력이 존재하게 된다. 이러한 잔류응력의 존재에 의한 부쉬(160)의 내구성 약화를 방지하기 위하여 가류성형 공정이 완료된 후 아우터슬리브(130)의 외경을 축소하는 공정(이하 '스웨이징 공정'이라 한다)을 실시하고 있었다. 따라서, 종래의 기술은 러버(140)에 존재하는 잔류응력을 감소하기 위하여 스웨이징 공정을 필요료 하였기 때문에 부쉬(160)의 성형공정이 복잡하고 생산성이 저하되는 문제점이 있었다.That is, after the vulcanization molding process of integrally forming the outer sleeve 130, the rubber 140, and the inner sleeve 150 is completed, the rubber 140 contracts to generate residual stress. In order to prevent the durability of the bush 160 due to the presence of such residual stress, a process of reducing the outer diameter of the outer sleeve 130 after completion of the vulcanization molding process (hereinafter referred to as a 'swaging process') was performed. Therefore, since the conventional technique requires a swaging process to reduce the residual stress present in the rubber 140, the molding process of the bush 160 is complicated and productivity is lowered.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 스웨이징 공정이 불필요한 차량 현가장치의 크로스멤버용 부쉬를 제공하기 위한 것이다.The present invention has been made to solve the above problems, and to provide a bush for the cross member of the vehicle suspension device that does not require a swaging process.

상기와 같은 목적을 달성하기 위해 본 발명의 차량 현가장치의 크로스멤버용 부쉬는, 관통공이 형성된 인너슬리브와; 상기 인너슬리브에 일체로 형성되는 러버와; 상기 러버에 일체로 형성되는 아우터슬리브로 이루어진 차량 현가장치의 크로스멤버용 부쉬에 있어서, 상기 부쉬는 크로스멤버에 장착되기 전인 자유상태에서 인너슬리브의 높이가 아우터슬리브의 높이 보다 높게 위치하고; 상기 인너슬리브와 상기 아우터슬리브를 연결하는 러버의 자유표면에는 경사부가 형성되며; 상기 인너슬리브가 차체에 접촉하는 부분이 다른 곳 보다 두께가 두껍도록 인너슬리브의 외면에는 경사면이 형성된 것을 특징으로 한다.In order to achieve the above object, the bush for the cross member of the vehicle suspension of the present invention, the inner sleeve is formed with a through hole; A rubber integrally formed with the inner sleeve; A bush for a cross member of a vehicle suspension composed of an outer sleeve integrally formed with the rubber, wherein the bush is positioned at a height higher than that of the outer sleeve in a free state before being mounted to the cross member; An inclined portion is formed on a free surface of the rubber connecting the inner sleeve and the outer sleeve; It is characterized in that the inclined surface is formed on the outer surface of the inner sleeve so that the portion where the inner sleeve is in contact with the vehicle body is thicker than other places.

이하, 본 발명의 바람직한 실시예에 대하여 첨부된 도3 및 도4를 참조하여 설명한다. 도3은 본 발명의 차량 현가장치의 크로스멤버용 부쉬의 단품 상태를 나타내는 단면도이고, 도4는 본 발명의 차량 현가장치의 크로스멤버용 부쉬에 의해 크로스멤버가 차체에 결합된 구조를 나타내는 단면도이다.Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS. 3 and 4. Figure 3 is a cross-sectional view showing a single unit state of the cross member bush of the vehicle suspension of the present invention, Figure 4 is a cross-sectional view showing a structure in which the cross member is coupled to the vehicle body by the cross member bush of the vehicle suspension of the present invention. .

도3 및 도4에 도시되어 있듯이, 본 발명의 부쉬(160)는 관통공(151)이 형성된 인너슬리브(150)와, 상기 인너슬리브(150)에 일체로 형성되는 러버(140)와, 상기 러버(140)에 일체로 형성되는 아우터슬리브(130)로 이루어져 있다.3 and 4, the bush 160 of the present invention is the inner sleeve 150, the through hole 151 is formed, the rubber 140 formed integrally with the inner sleeve 150, and The outer sleeve 130 is formed integrally with the rubber 140.

상기 부쉬(160)는 크로스멤버(100)에 장착되기 전인 자유상태 즉, 가류성형이 완료된 부쉬의 단품상태에서 인너슬리브(130)의 높이가 아우터슬리브(150)의 높이 보다 높게 위치하고 있다.The height of the inner sleeve 130 is higher than that of the outer sleeve 150 in the free state before the bush member 160 is mounted on the cross member 100, that is, in a single state of the bush in which vulcanization is completed.

또한, 상기 인너슬리브(130)와 상기 아우터슬리브(150)를 연결하는러버(140)의 자유표면에는 경사부(142)가 형성되어 있다.In addition, the inclined portion 142 is formed on the free surface of the rubber 140 connecting the inner sleeve 130 and the outer sleeve 150.

상기 인너슬리브(130)가 차체(120)에 접촉하는 부분은 볼트(110)의 헤드와 접촉하는 부분 보다 두께가 두껍도록 인너슬리브(130)의 외면에는 경사면(152)이 형성되어 있다.An inclined surface 152 is formed on an outer surface of the inner sleeve 130 so that the inner sleeve 130 is in contact with the vehicle body 120 so that the thickness of the inner sleeve 130 is thicker than the portion in contact with the head of the bolt 110.

본 발명의 부쉬(160)가 차량에 장착되는 구조는 종래의 기술과 동일하기 때문에 상세한 설명은 생략한다.Since the structure in which the bush 160 of the present invention is mounted on a vehicle is the same as in the related art, a detailed description thereof will be omitted.

이하, 본 발명의 작용에 대하여 설명한다.Hereinafter, the operation of the present invention will be described.

본 발명의 부쉬(160)는 가류성형 후 아우터슬리브(150)에 대하여 스웨이징 공정을 실시하지 않았기 때문에 부쉬(160)를 차체에 장착하기 전에는 러버(140) 내부에 잔류응력이 존재하는 상태이다.Since the bush 160 of the present invention does not perform the swaging process on the outer sleeve 150 after vulcanization, the residual stress exists in the rubber 140 before the bush 160 is mounted on the vehicle body.

부쉬(160)가 고정된 크로스멤버(100)를 볼트(110) 및 너트(112)를 이용하여 차체(120)에 고정하고 차량을 지면에 위치시킨 경우, 차량의 무게로 인하여 부쉬(160)에는 하부방향으로 하중이 작용하게 된다.When the cross member 100 having the bush 160 fixed thereto is fixed to the vehicle body 120 using the bolt 110 and the nut 112 and the vehicle is positioned on the ground, the bush 160 may be disposed due to the weight of the vehicle. The load acts downward.

부쉬(160)에 작용하는 하중은 인너슬리브(150)를 통하여 러버(140)에 전달되기 때문에, 인너슬리브(150)는 하부로 이동하게 된다. 그런데, 인너슬리브(150)에는 경사면(152)이 형성되어 있기 때문에, 인너슬리브(150)가 하부로 이동하는 경우, 경사면(152)에 의해 러버(140)는 압축변형이 일어난다. 즉, 러버(140)의 자유표면에 형성된 경사부(142)가 하향 이동하면서 아우터슬리브(150)의 내면과 인너슬리브(130)의 외면 사이의 거리가 짧아지게 되어 러버(140)에는 압축력이 작용하는 것이다.Since the load acting on the bush 160 is transmitted to the rubber 140 through the inner sleeve 150, the inner sleeve 150 moves downward. However, since the inclined surface 152 is formed on the inner sleeve 150, when the inner sleeve 150 moves downward, the rubber 140 is deformed by the inclined surface 152. That is, as the inclined portion 142 formed on the free surface of the rubber 140 moves downward, the distance between the inner surface of the outer sleeve 150 and the outer surface of the inner sleeve 130 is shortened, so that the compressive force acts on the rubber 140. It is.

따라서, 경사면(152)에 의한 러버(1400의 압축변형은, 부쉬(160)의 단품상태에서 러버(140) 내부에 존재하는 잔류응력을 제거하게 된다.Accordingly, the compression deformation of the rubber 1400 by the inclined surface 152 removes the residual stress existing in the rubber 140 in the single state of the bush 160.

즉, 본 발명은 경사면(152)에 의해 러버(140) 내부에 존재하는 잔류응력을 제거할 수 있기 때문에, 부쉬(160)의 단품상태에서 스웨이징 공정이 없어도, 부쉬(160)의 내구성능을 향상시킬 수 있게 된다.That is, in the present invention, since the residual stress existing in the rubber 140 can be removed by the inclined surface 152, the durability of the bush 160 can be improved even if there is no swaging process in the single unit of the bush 160. It can be improved.

또한, 본 발명에서 인너슬리브(150)가 차체(120)에 결합되는 부분은 다른 곳 보다 두께가 두껍게 형성되어 있기 때문에, 인너슬리브(150)가 차체(120)에 접촉되는 면적이 증대되어 차량 운행시 크로스멤버(100)에 작용하는 반복적인 하중에 의해 접촉부에서 발생하는 국부적인 손상을 방지하는 작용을 한다.In addition, in the present invention, since the inner sleeve 150 is coupled to the vehicle body 120, the thickness of the inner sleeve 150 is greater than that of the other parts, so that the area in which the inner sleeve 150 contacts the vehicle body 120 increases and the vehicle runs. It acts to prevent the local damage occurring in the contact portion by the repetitive load acting on the cross member 100 at the time.

본 발명은, 인너슬리브의 외면에 경사면을 형성하고 러버의 자유표면에 형성된 경사부의 구성을 채택하였기 때문에, 부쉬를 가류성형한 후 스웨이징 공정이 없어도 러버 내부에 작용하는 잔류응력을 제거할 수 있어서 부쉬의 성형이 용이하며, 생산성을 향상시킬 수 있다.According to the present invention, since the inclined surface is formed on the outer surface of the inner sleeve and the inclined portion formed on the free surface of the rubber is adopted, the residual stress acting on the inside of the rubber can be eliminated without the swaging process after vulcanizing the bush The molding of the bush is easy and the productivity can be improved.

또한, 본 발명은, 인너슬리브가 차체에 접촉되는 면적을 증대하였기 때문에 차체에 집중응력이 발생되지 않으며 인너슬리브가 접촉하고 있는 차체에 국부적인 손상이 발생되지 않도록 한다.Further, according to the present invention, since the inner sleeve increases the area in contact with the vehicle body, no concentrated stress is generated in the vehicle body, and local damage does not occur in the vehicle body that the inner sleeve is in contact with.
