Description

자동차용 특수 와셔{Special washer for automobile}Special washer for automobile

본 발명은 자동차용 특수 와셔에 관한 것으로서, 보다 상세하게는 자동차의 실린더 헤드측과 흡배기 매니폴드의 장착부에 사용되는 특수 와셔에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a special washer for automobiles, and more particularly, to a special washer for use in a cylinder head side of an automobile and a mounting portion of an intake and exhaust manifold.

통상적으로 각종 너트의 체결력 향상을 위하여 스프링 와셔를 사용하는데, 자동차의 실린더 헤드측에 장착되는 흡, 배기 매니폴드의 장착부위에도 스프링 와셔가 사용된다.Generally, a spring washer is used to improve fastening force of various nuts, and a spring washer is also used at a mounting portion of an intake and exhaust manifold mounted on a cylinder head side of a vehicle.

즉, 첨부한 도 4에 도시한 바와 같이, 실린더 헤드측의 흡, 배기 매니폴드 장착부에는 스터드가 돌출되어 형성되어 있는데, 상기 스터드가 흡, 배기 매니폴드의 플랜지를 관통되고, 이 관통된 스터드에 스프링 와셔를 삽입한 후, 너트를 일정한 토오크치로 체결시킴으로써 흡, 배기 매니폴드가 장착되어 진다.That is, as shown in FIG. 4, studs protrude from the intake and exhaust manifold mounting portions on the cylinder head side, and the studs penetrate through the flanges of the intake and exhaust manifolds, After the spring washer is inserted, the intake and exhaust manifolds are mounted by tightening the nut to a constant torque value.

이때, 상기 스프링와셔와 너트는 실린더 헤드와 흡, 배기 매니폴드의 내부에 있는 흡, 배기 가스가 새어나오지 않도록 그 체결력을 항상 유지하여야 한다.At this time, the spring washer and nut should always maintain the fastening force so that the suction and exhaust gas in the cylinder head and the suction and exhaust manifolds do not leak.

그러나, 상기 실린더 헤드측에 장착되는 흡, 배기 매니폴드 장착부위의 스프링 와셔만으로는 엔진의 고출력화에 따른 폭발압 증대로 너트가 플랜지 측에 가하고 있는 조임 토오크를 유지하기가 어려워 풀림현상이 발생하게 됨에 따라 실린더 내부 및 매니폴드로부터 흡, 배기 가스의 리킹 현상이 발생하는 단점이 있다.However, only the spring washer on the suction and exhaust manifold mounting portion mounted on the cylinder head side is difficult to maintain the tightening torque applied to the flange by the explosion pressure due to the high output of the engine, causing loosening. Accordingly, there is a disadvantage in that leakage of intake and exhaust gases occurs inside the cylinder and from the manifold.

따라서, 본 발명은 상기와 같은 단점을 감안하여 안출한 것으로써, 탄성강도를 보강하여 플랜지측에 가하고 있는 너트의 조임 토오크를 유지할 수 있고, 실린더 헤드와 스터드 간의 체결력을 향상하여, 흡, 배기 가스의 시일성을 증대할 수 있으며, 슬리브와 특수 와셔, 스프링 와셔를 차례대로 스터드에 체결하여, 엔진의 진동 압축시 특수 와셔, 스프링 와셔가 슬리브에 끼워져 있음으로써 튕겨겨 나가는 것을 방지하여, 안전성 있고 체결력이 향상된 자동차용 특수 와셔를 제공하는데 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of the above disadvantages, and it is possible to maintain the tightening torque of the nut applied to the flange side by reinforcing elastic strength, improving the tightening force between the cylinder head and the stud, and intake and exhaust gas. It is possible to increase the sealing performance, and the sleeve, the special washer, and the spring washer are fastened to the studs one by one, and when the engine is vibrated, the special washer and the spring washer are prevented from being thrown out by being fitted in the sleeve, thereby making it safe and fastening. The purpose is to provide these improved special washers for automobiles.

이하 첨부 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

흡, 배기 매니폴드가 장착되도록 자동차의 실린더 헤드측에 형성된 스터드(18)의 양쪽에 슬라이드단(22)을 갖는 슬리브(20)를 끼우되, 이 슬리브(20)의 중앙 원주면에 2개의 압착 가능한 일반 스프링 와셔(14a, 14b)를 끼우고, 상기 슬리브(20)의 양쪽에는 슬라이드단(22)에 걸리며 슬라이드 되는 특수와셔(12a, 12b)를 일정한 조임 토오크치로 너트(16)를 조여, 안정적인 토오크치를 형성하는 것을 특징으로 한다.A sleeve 20 having a slide end 22 is fitted to both sides of the studs 18 formed on the cylinder head side of the vehicle so that the intake and exhaust manifolds are mounted, and two crimps are pressed on the central circumferential surface of the sleeve 20. Insert the general spring washers 14a and 14b as much as possible, and fasten the nut 16 with a constant tightening torque by fastening the special washers 12a and 12b which are caught on the slide ends 22 and slide on both sides of the sleeve 20. It is characterized by forming a torque value.

본 발명을 좀 더 상세히 설명하면 다음과 같다.The present invention is described in more detail as follows.

첨부한 도 2는 본 발명에 따른 특수 와셔(12a, 12b)의 형상을 나타내는 정면도와 측면도이다.2 is a front view and a side view showing the shapes of the special washers 12a and 12b according to the present invention.

특수 와셔(12)에 있어서 그 내경면이 바깥쪽으로 두께의 3분의 1지점까지 경사지게 형성되어, 중공의 원통형으로써 그 외주면 양단에는 바깥쪽으로 상향 경사진 슬라이드가 형성되어 있는 상기 슬리브(20)의 양쪽 외주면에 형성된 슬라이드단(22)과 밀착되며 슬라이드 되는 것을 특징으로 하여 제작된다.In the special washer 12, the inner diameter surface thereof is inclined outward to one third of the thickness, and both sides of the sleeve 20 are formed in a hollow cylindrical shape and slides upwardly outwardly formed at both ends of the outer circumferential surface thereof. It is produced by being in close contact with the slide end 22 formed on the outer circumferential surface.

첨부한 도 3은 본 발명에 따른 특수와셔(12a, 12b)의 사용 상태를 나타내는 사시도로써, 특수와셔(12a, 12b)는 스프링 와셔(14a, 14b)의 탄성력으로 상부의 플랜지와 하부의 너트에 일정한 힘을 가하며 체결되어 있다.3 is a perspective view showing a state of use of the special washers 12a and 12b according to the present invention, wherein the special washers 12a and 12b are connected to the upper flange and the lower nut by the elastic force of the spring washers 14a and 14b. It is fastened by applying a constant force.

폭발압으로 인해 특수와셔(12a, 12b)는 강한 압축력을 받는 바 슬리브(20)를 축으로 하여 스프링 와셔(14a, 14b)의 탄성력을 받고 슬리브(20)의 길이만큼의 거리를 유지하여 플랜지(10)측과 너트(16)측에 압축에 의한 반작용력을 가함으로써 그 탄성력을 플랜지(10)와 너트(16)의 강한 체결을 유지하게 된다.Due to the explosion pressure, the special washers 12a and 12b receive the elastic force of the spring washers 14a and 14b around the bar sleeve 20 which is subjected to the strong compressive force, and maintain the distance by the length of the sleeve 20 so that the flange ( By applying a reaction force by compression to the 10) side and the nut 16 side, the elastic force is maintained at the strong coupling between the flange 10 and the nut 16.

이상 상술한 바와 같이 본 발명에 따른 자동차용 특수 와셔에 의하면 스터드의 체결 작업시 플랜지와 너트 간의 토오크치를 일정하게 유지함으로써, 흡, 배기 가스의 리킹을 방지할 수 있고, 와셔를 슬리브 위에 체결함으로써 압축시 와셔가 이탈하는 가능성을 미연에 방지함으로써 안정성 있고 체결력이 향상된 너트를 제공하는 잇점이 있다.As described above, according to the special washer for automobile according to the present invention, by maintaining the torque value between the flange and the nut during the fastening of the stud, it is possible to prevent the intake and exhaust gas from leaking, and by pressing the washer on the sleeve to compress It has the advantage of providing a stable and improved tightening force by preventing the possibility of the seal washer falling off.
