차량용 쇽업소버의 너클브라켓 구조Knuckle bracket structure of vehicle shock absorber

본 발명은 차량용 쇽업소버(Shock Absorber)의 너클브라켓(Knuckle Bracket) 구조에 관한 것으로서, 특히 쇽업소버의 아우터셀(Outer Shell) 하단 외부에 압입 설치되는 너클브라켓에 파일럿홀(Pilot Hole)과 압입홀과 다수개의 요홈을 형성시켜 너클브라켓의 금형 작업성과 압입설치작업성과 용접고정작업성을 증대시킨 차량용 쇽업소버의 너클브라켓 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knuckle bracket structure of a shock absorber for a vehicle. More particularly, the present invention relates to a knuckle bracket that is press-fitted outside the lower end of an outer shell of a shock absorber, And a knuckle bracket structure for a vehicle shock absorber in which a plurality of grooves are formed to increase the workability of the knuckle bracket, the press-fitting workability, and the welding workability.

일반적으로 쇽업소버는 차량의 현가함과 차체 사이에 설치하여 차량의 주행중 노면에서 타이어를 통해 차체로 전달되는 충격과 진동을 감쇄 또는 흡수시켜 차체의 진동과 충격력을 최소화시킬 수 있게 한 것이다.Generally, the shock absorber is installed between the suspension of the vehicle and the vehicle body, so that the shock and vibration transmitted to the vehicle body through the tire from the road surface during running of the vehicle can be attenuated or absorbed to minimize the vibration and impact force of the vehicle body.

이러한 쇽업소버의 아우터셀 하단 외부에는 쇽업소버와 차량의 너클암 사이를 고정설치할 수 있는 너클브라켓이 구비된다.A knuckle bracket capable of fixing the shock absorber and the knuckle arm of the vehicle is provided outside the lower end of the outer shell of the shock absorber.

상기한 너클브라켓은 너클암과 쇽업소버의 결합견고성을 유지하기 위해 일정강도를 유지시키도록 하고, 조립 견고성을 높이기 위해 아우터셀에 압입된 상태에서 소정부위를 용접고정시키며, 차량의 무게 하중을 가능한 최소화시킬 수 있는 구조로 되어 있다.The knuckle bracket described above is designed to maintain a constant strength in order to maintain the joint strength between the knuckle arm and the shock absorber. To increase the rigidity of the knuckle bracket, a predetermined portion of the knuckle bracket is welded and fixed to the outer shell. So that it can be minimized.

이와같은 종래의 쇽업소버(10)의 너클브라켓(20)을 설명하면 쇽업소버(10)의 아웃터셀(11)의 외주연에 삽입 설치될 수 있도록 원통형의 베이스(21)를 구비하고, 이 베이스(21)의 배면 중앙부에는 단수개의 홀(21A)을 형성하며, 베이스(21)의 일측에는 "ㄷ"형 브라켓(26)을 용접고정하고, 브라켓(26)의 측면에는 복수개의 고정공(27)을 형성한다.The knuckle bracket 20 of the conventional shock absorber 10 has a cylindrical base 21 so as to be inserted into the outer periphery of the outer shell 11 of the shock absorber 10, Type bracket 26 is welded to one side of the base 21 and a plurality of fixing holes 27 are formed in the side surface of the bracket 26 ).

상기한 너클브라켓(20)은 쇽업소버(10)의 아우터셀(11) 하단 외부에 압입설치 한후 도 7에서 보는 바와같이 하단부 다수부위를 용접시켜 아우터셀(11)과 고정시킨다.The knuckle bracket 20 is press-fitted outside the lower end of the outer shell 11 of the shock absorber 10, and a plurality of lower ends are welded to fix the outer shell 11 as shown in FIG.

이러한 너클브라켓(20)은 쇽업소버(10)를 차체의 너클암(NA)에 고정설치될 수 있도록 브라켓(26)에 너클암(NA)을 삽착시킨후 고정공(27)을 통해 체결부재를 체결시킨 것이다.The knuckle bracket 20 has a knuckle arm NA attached to the bracket 26 so that the shock absorber 10 can be fixed to the knuckle arm NA of the vehicle body, Respectively.

그러나 상기 너클브라켓(20)은 쇽업소버(10)의 아우터셀(11) 외부에 베이스(21)를 삽착시킨후 베이스(21) 하단부와 아우터셀(11) 하단부의 다수부위를 용접고정시킴에 따라 고정상태가 견고하지 못하여 쇽업소버(10)의 조립견고성이 취약하였고, 너클브라켓(20)의 베이스(21)를 원통형으로 형성함에 따라 프레스 금형작업에 의해 제작되는 너클브라켓(10)의 제작성이 좋지 못하였으며, 무게 하중이 비교적으로 큼에 따라 쇽업소버(10)는 차량에 적용시 차량 전체의 중량을 증가시키는 폐단이 있었다.However, since the knuckle bracket 20 is installed with the base 21 outside the outer cell 11 of the shock absorber 10, the lower end of the base 21 and the lower end of the outer cell 11 are fixed by welding The assembling of the knuckle bracket 10 produced by the press-molding work as the base 21 of the knuckle bracket 20 is formed into a cylindrical shape is difficult because the fixed state is not rigid and the assembling robustness of the shock absorber 10 is poor. The shock absorber 10 had a problem of increasing the overall weight of the vehicle when it was applied to the vehicle, as the weight load was relatively large.

전술한 종래 기술들은 쇽업소버의 아우터셀 하단부에 압입되는 너클브라켓의 원통형 베이스의 압입설치 작업성이 좋지 못하였고, 무게 하중이 큼에 따라 차량 전체의 중량을 증대시키는 폐단이 발생하였으며, 완성되는 원통형의 베이스 제작작업이 좋지 못한 문제점이 있었다.In the above-described conventional techniques, the cylindrical base of the knuckle bracket press-fitted into the lower end portion of the outer shell of the shock absorber has poor press-fitting workability. As the weight load increases, the weight of the entire vehicle increases. There is a problem in that the base production work of the base is poor.

본 발명은 상기와 같이 종래의 문제점을 해결하기 위하여 안출한 것으로서, 쇽업소버의 아우터셀 하단 외부에 압입 설치되는 너클브라켓에 파일럿홀과 압입홀과 다수개의 요홈을 형성시켜 너클브라켓의 금형 작업성과 압입설치작업성과 용접고정작업성을 높이고, 무게 하중을 최소화시켜 쇽업소버의 중량을 감소시킬 수 있게 한 것을 목적으로 한다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a knuckle bracket which is press-fitted outside the lower end of an outer shell of a shock absorber, It is possible to reduce the weight of the shock absorber by increasing the installation workability and welding fix workability and minimizing the weight load.

And the knuckle bracket 20 is press-fitted into the lower end of the lower outer shell 11 of the lower spring seat S and then the grooves 24, Welded to a large number of lower portions.

이와같이 된 본 발명의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

도 4에서 보는 바와같이 원통형의 베이스(21)에 복수개의 파일럿홀(22)을 형성시킴에 따라 프레스금형에서 원형으로 제작되는 너클브라켓(20)의 금형 작업성이 기샌됨은 물론 베이스(21)의 형상 변형을 방지할 수 있게 한다.4, the plurality of pilot holes 22 are formed in the cylindrical base 21, so that the workability of the mold of the knuckle bracket 20, which is formed in a circular shape in the press die, Thereby making it possible to prevent shape deformation.

상기 너클브라켓(10)에는 베이스(21)에 복수개의 압입홀(23)을 형성시킴에 따라 아우터셀(11)에 압입설치시 인장성을 줌으로서 압입작업성을 보다 쉽게 할 수 있게 한다.The plurality of press-fit holes 23 are formed in the base 21 of the knuckle bracket 10 so that the press-in workability can be made easier by providing the outer cell 11 with a tensile force at the time of press-fitting.

이렇게 아우터셀(11)에 압입 설치된 너클브라켓(20)의 베이스(21)에는 상단과 하단에 각각 요홈(24)(25)을 형성시켜 이에 용접작업을 행하므로서, 너클브라켓(20)의 결합견고성을 높인 것이다.The base 21 of the knuckle bracket 20 press-fitted into the outer shell 11 is formed with grooves 24 and 25 at the upper and lower ends thereof to weld the knuckle bracket 20, .

또한 너클브라켓(20)의 베이스(21)에 각각 파일럿홀(22)과 압입홀(23)과 요홈(240(25)에 의해 베이스(21) 전체에서 보정부위를 제거시킴에 따라 중량을 감소시킬 수 있게 한 것이다.The weight of the knuckle bracket 20 is reduced by removing the correction portion from the entire base 21 by the pilot hole 22, the press-fit hole 23 and the groove 240 (25) It is possible.

따라서, 차량의 전·후방에 복수개씩 설치되는 쇽업소버(10)는 기존의 쇽업소버보다 약 200g 정도의 무게 중량을 감소시킬 수 있게 하므로서, 차량 전체 중량을 감소시킬 수 있게 한 것이다.Therefore, a plurality of shock absorbers 10 installed at the front and rear of the vehicle can reduce the weight of about 200 g compared to the conventional shock absorber, thereby reducing the overall weight of the vehicle.

이상에서와 같이 본 발명은 쇽업소버의 아우터셀 하단 외부에 압입 설치되는 너클브라켓에 파일럿홀과 압입홀 다수개의 요홈을 형성시켜 너클브라켓의 금형 작업성과 압입설치작업성과 용접고정작업성을 증대시키고, 쇽업소버를 너클암에 견고하게 고정결합이 가능하여 내구성을 증진시키며, 차량의 중량감소를 이룰 수 있게 한 효과가 있다.As described above, according to the present invention, the knuckle bracket press-fitted into the lower end of the outer shell of the shock absorber is provided with a plurality of recesses in the pilot hole and the press-fit hole, thereby increasing the workability of the knuckle bracket, It is possible to firmly fix the shock absorber to the knuckle arm, thereby improving the durability and reducing the weight of the vehicle.
