도시된 바와 같이 본 발명은 캠샤프트(100)를 보호지지하는 캠샤프트 캡(105)의 양측에 형성된 볼팅홀(105a)과 실린더헤드(110)측에 형성된 볼팅홀(110a)을 연결시켜 상기 캠샤프트 캡(105)을 체결시키기 위한 것으로, 머리부(115a)와 축부(115b)로 이루어진 볼트(115)의 머리부(115a) 배면으로부터 소정량 더 돌출된 접압돌기부(115c)가 머리부(115a)의 배면을 따라 돌출형성된다.As shown in the present invention by connecting the bolting hole (105a) formed on both sides of the cam shaft cap 105 for protecting the cam shaft 100 and the bolting hole (110a) formed on the cylinder head 110 side the cam In order to fasten the shaft cap 105, the contact protrusion 115c which protrudes a predetermined amount further from the back of the head 115a of the bolt 115 consisting of the head 115a and the shaft 115b is the head 115a. Protruding along the back of

이때, 상기 볼트(115)의 축부(115b)로 삽입되어 머리부(115a) 배면에 돌출형성된 접압돌기부(115c)와 그 상면(120a)이 면접압되고, 상기 캠샤프트 캡(105)의 상면(105b)에 그 배면(120b)이 면접압되는 와셔(120)가 구비된다.At this time, the contact protrusion 115c and the upper surface 120a which are inserted into the shaft 115b of the bolt 115 and protruded on the rear surface of the head 115a are interviewed and the upper surface of the camshaft cap 105 ( The washer 120 in which the back surface 120b is interviewed is provided in 105b).

한편, 상기 볼트(115)의 접압돌기부(115c) 끝단은 면을 갖는 접압면(115d)이 형성되어 상기 와셔(120)의 상면(120a)과 면접압된다.On the other hand, the end of the contact protrusion (115c) of the bolt 115 has a contact surface 115d having a surface is in contact with the upper surface (120a) of the washer 120.

이와 같이 이루어진 본 발명에 따른 자동차용 캠샤프트 캡체결용 볼트(115)를 이용하여 상기 캠샤프트의 캡(105)을 실린더헤드(110)측에 고정시키고자 할 때에는 첨부된 도면 도 4 내지 도 6에 도시된 바와 같이 상기 캠샤프트 캡(105)의 양측에 형성된 볼팅홀(105a)과 실린더헤드(110)측에 형성된 볼팅홀(110a)을 일치시킨 후, 와셔(120)가 그 축부(115b)로 삽입되어 있는 볼트(115)를 상기 캠샤프트 캡(105)의 볼팅홀(105a)에 삽입시켜 체결시키게 되면, 상기 와셔(120)는 캠샤프트 캡(105)의 상면(105b)에 그 배면(120b)이 접압되고, 상면(120a)은 볼트(115)의 접압돌기부(115c) 접압면(115d)에 면접압되게 되고, 상기 캠샤프트 캡(105)의 상면(105b)은 와셔(120)의 배면(120b)과 면접압되게 된다.When the cam shaft cap 105 of the cam shaft is fixed to the cylinder head 110 using the cam shaft cap fastening bolt 115 according to the present invention, the accompanying drawings are shown in FIGS. 4 to 6. As shown in FIG. 5, after the bolting holes 105a formed at both sides of the camshaft cap 105 and the bolting holes 110a formed at the cylinder head 110 are matched, the washer 120 has its shaft portion 115b. When the bolt 115 is inserted into the bolting hole 105a of the camshaft cap 105 to be fastened, the washer 120 is formed on the rear surface 105b of the camshaft cap 105. 120b) is pressed, the upper surface (120a) is in contact with the contact surface 115d of the pressure projection (115c) of the bolt 115, the upper surface (105b) of the cam shaft cap 105 of the washer 120 Interview pressure with the back surface 120b.

이때, 캠샤프트(100)의 고속회전으로 인한 캠샤프트 캡(105)의 유동됨을 방지하기 위해 상기 볼트(115)를 더욱 조임시키게 되는데, 이때 상기 볼트(115)의 조임력에 의해 상기 볼트(115)의 접압돌기부(115c) 접압면(115d)이 캠샤프트 캡(105)의 상면(105b)과 면접압되어 있는 와셔(120)의 상면(120a)을 조임시키게 된다.At this time, the bolt 115 is further tightened to prevent the cam shaft cap 105 from flowing due to the high speed rotation of the cam shaft 100. At this time, the bolt 115 is tightened by the tightening force of the bolt 115. The contact surface 115d of the contact projection 115c tightens the upper surface 120a of the washer 120 which is in contact with the upper surface 105b of the cam shaft cap 105.

이로 인하여 와셔(120)의 배면(120b)은 상기 캠샤프트 캡(105)의 상면(105b)과 면접압되면서 상기 캠샤프트 캡(105)의 뒤틀림 없이 볼트(115)의 체결이 이루어지게 된다.As a result, the rear surface 120b of the washer 120 is contacted with the upper surface 105b of the camshaft cap 105 while the bolt 115 is fastened without being twisted by the camshaft cap 105.

즉, 볼트(115)의 머리부(115a) 배면에 돌출형성된 접압돌기부(115c)와 와셔(120)의 상면(120a)과 접압되는 면의 면적에 비해 캠샤프트 캡(105)의 상면(105b)과 와셔(120)의 배면(120b)과의 접압되는 면의 면적이 상대적으로 크므로 그 만큼의 마찰면적도 크다.That is, the upper surface 105b of the camshaft cap 105 is compared with the area of the contact surface contacting the upper surface 120a of the contact protrusion 115c and the washer 120 formed on the rear surface of the head 115a of the bolt 115. Since the area of the surface pressed against the back surface 120b of the washer 120 is relatively large, the friction area is also large.

따라서, 와셔(120)의 상면(120a)을 접압하는 볼트(115)의 접압돌기부(115c)의 접압면(115d)에서 발생되는 마찰력이 와셔의 배면(120b)에서 발생되는 마찰력에 비해 상대적으로 적은 마찰력이 갖으므로 볼트(115) 조임시 상기 캠샤프트 캡(105)의 비틀림을 방지할 수 있게 된다.Therefore, the frictional force generated at the contact surface 115d of the contact protrusion 115c of the bolt 115 contacting the upper surface 120a of the washer 120 is relatively less than the friction force generated at the back surface 120b of the washer. Since the friction force is provided, it is possible to prevent the cam shaft cap 105 from twisting when the bolt 115 is tightened.

상술한 본 발명과 같이 실린더헤드측과 캠샤프트 캡을 체결시키는 매개체인 볼트의 접압면에 접압돌기부를 형성하고, 볼트의 축부로 삽입구비되어 접압돌기부와 접압되는 와셔를 구비하여, 상기 볼트의 접압면적을 최소화하고 와셔와 캠샤프트 캡의 상면의 접지면적은 상대적으로 크게하도록 함으로써 볼트 조임시 조임방향으로 캠샤프트 캡이 뒤틀림되는 것을 방지할 수 있는 것이다.As in the present invention described above, a contact projection is formed on the contact surface of the bolt, which is a medium for fastening the cylinder head side and the cam shaft cap, and is provided with a washer inserted into the shaft portion of the bolt to contact the contact projection. By minimizing the area and making the ground area of the upper surface of the washer and camshaft cap relatively large, it is possible to prevent the camshaft cap from twisting in the tightening direction when tightening the bolt.
