CONSTITUTION: A stud bolt(22) for fixing a wheel and a drum of a vehicle is composed of a drum nut(8) for fixing the drum combined to an end and caulked; a wheel nut(12) combined to other end to fix the wheel; and a recessed part(24) formed to a section surface at which the drum nut is combined to the stud bolt to increase caulking force and prevent the separation and loose of the drum nut.

Description

차량의 휠 및 드럼 고정용 스터트 볼트{stud bolt for fixing wheel and drum of a vehicle}Stud bolt for fixing wheel and drum of a vehicle

본 발명은 차량의 휠 및 드럼 고정용 스터드 볼트에 관한 것이다.The present invention relates to a stud bolt for fixing a wheel and a drum of a vehicle.

드럼타입의 제동방식을 적용하는 차량에서는 휠과 드럼을 스터드 볼트를 사용하여 고정하는데, 도1에 도시한 바와 같이, 스터드 볼트(2)의 일측에는 허브(4)와 드럼(6)이 끼워져 드럼너트(8)에 의해 고정되고, 스터드 볼트(2)의 타측에는 타이어가 장착되는 휠(10)이 끼워져 휠너트(12)에 의해 고정된다.In a vehicle using a drum-type braking method, the wheel and the drum are fixed by using a stud bolt. As shown in FIG. 1, the hub 4 and the drum 6 are fitted to one side of the stud bolt 2 so that the drum is inserted into the drum. It is fixed by the nut 8 and the wheel 10 on which the tire is mounted is fitted to the other side of the stud bolt 2 and fixed by the wheel nut 12.

상기 드럼(6)은 반 영구적으로 사용되므로 드럼너트(8)를 체결할 후에는 스터드 볼트(2)의 끝단부에 코킹작업하여 드럼너트의 이탈 및 풀림을 방지한다. 코킹작업은 너트 체결후 스터드 볼트(2)의 끝단부에 삼각 혹은 사각 피라미드 펀치를 이용하여 3~4곳을 고정하는 작업이다.Since the drum 6 is used semi-permanently, after the drum nut 8 is fastened, the drum 6 is caulked at the end of the stud bolt 2 to prevent the drum nut from being separated and loosened. Caulking work is to fix three to four places using a triangular or square pyramid punch at the end of the stud bolt (2) after tightening the nut.

종래 스터드 볼트는 끝단면은 평면으로 되어 있고, 이 평면에 코킹작업이 행해졌다.Conventionally, the stud bolt has a flat end surface, and caulking is performed on this flat surface.

그런데, 이와 같이 끝단면이 평면으로 된 스터드 볼트에 행해진 코킹은 취약하여, 드럼너트의 체결력 저하로 인해 풀림이 발생하여 휠 너트의 풀림 및 스터드볼트가 파손되는 경우가 생기며, 휠 및 타이어의 교환후 휠 너트의 조임시 드럼너트가 이탈되는 문제점이 있었다.However, the caulking performed on the stud bolt having the flat end surface in this way is weak, and loosening occurs due to the lowering of the tightening force of the drum nut, which may lead to loosening of the wheel nut and breaking of the stud bolt. There was a problem that the drum nut is separated when tightening the wheel nut.

그리고, 차량은 주행 중에 끊임없는 반복 인장, 압축 및 전단력이 스터드 볼트에 가해지므로, 드럼너트의 풀림 및 유동이 발생하기가 매우 쉬워서, 이로 인해 스터드 볼트가 파손되고 타이어가 이탈하여 차량 전복에 이르는 치명적 사고가 발생한다는 문제점이 있었다.In addition, since the vehicle is continuously subjected to repeated tension, compression, and shear force while driving, stud bolts are very easy to loosen and flow, which causes the stud bolts to break off and tires to fall, leading to the vehicle overturning. There was a problem that an accident occurred.

따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 드럼너트와의 코킹력을 높여 드럼너트의 이탈 및 풀림을 방지하는 차량의 휠 및 드럼 고정용 스터드 볼트를 제공하는 데 있다.Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a wheel and a stud bolt for fixing the drum of the vehicle to prevent the separation and loosening of the drum nut by increasing the coking force with the drum nut. .

여기서, DI는 원추면 홈의 바닥면 내경이고, DO는 스터드 볼트의 나사외경이이며, P는 스터드 볼트의 나사 피치이다.Here, DI is the bottom inner diameter of the conical groove, DO is the thread outer diameter of the stud bolt, and P is the thread pitch of the stud bolt.

상기 스터드 볼트(22)의 단부면과 상기 드럼너트(8)의 단부면 사이의 거리(f)는 약 3mm가 되도록 드럼너트(8)를 조여 결합하는 것이 바람직하다.The distance f between the end face of the stud bolt 22 and the end face of the drum nut 8 is preferably fastened to the drum nut 8 such that the distance f is about 3 mm.

도3은 본 발명의 제2실시예에 의한 차량의 휠 및 드럼 고정용 스터드 볼트이다. 도시한 바와 같이, 본 실시예에서 드럼너트(8)가 체결되는 단부면에는 원통면(34a)의 단부에 원추면(34b)이 형성된 홈으로 된 리세스부(34)가 형성되어있다.3 is a stud bolt for fixing a wheel and a drum of a vehicle according to a second embodiment of the present invention. As shown in the drawing, a recessed portion 34 is formed in the end face of the drum nut 8 to which the drum nut 8 is fastened, the groove 34 having a conical surface 34b formed at the end of the cylindrical face 34a.

상기 원추면의 원추 각도(θ)는 하기 식 2를 만족하는 범위내에서 110°~ 130°이고, 원통면의 깊이(Lp)는 스터드 볼트 나사피치의 2~3배 인 것이 바람직하다.Cone angle (θ) of the conical surface is 110 ° ~ 130 ° within the range satisfying the following formula 2, the depth (Lp) of the cylindrical surface is preferably 2-3 times the stud bolt screw pitch.

원통면의 내경은 다음 식 2를 만족하게 가공된다.The inner diameter of the cylindrical surface is machined to satisfy the following equation (2).

DI = DO - (4P ~ 6P) [식 2]DI = DO-(4P ~ 6P) [Equation 2]

여기서, DI는 원통면의 내경이고, DO는 스터드 볼트의 나사외경이며, P는 스터드 볼트의 나사 피치이다.Here, DI is the inner diameter of the cylindrical surface, DO is the thread outer diameter of the stud bolt, P is the thread pitch of the stud bolt.

상기 스터드 볼트(32)의 단부면과 상기 드럼너트(8)의 단부면 사이의 거리(f)는 상기 원통면의 깊이(Lp)와 동일하게 되도록 드럼너트(8)를 조여 결합하는 것이 바람직하다.Preferably, the distance f between the end face of the stud bolt 32 and the end face of the drum nut 8 is tightened to be coupled to the drum nut 8 such that it is equal to the depth Lp of the cylindrical surface. .

이와 같이 구성된 스터드 볼트(22, 32)에 드럼너트(8)을 끼워 코킹작업을 할 결과, 조임토오크 및 코킹력이 현저히 향상되어 스터드 볼트의 파손이 방지되고 드럼너트의 이탈 및 풀림을 방지됨을 확인할 수 있었다.As a result of the coking operation by inserting the drum nut 8 into the stud bolts 22 and 32 configured as described above, tightening torque and the caulking force are remarkably improved to prevent breakage of the stud bolt and to prevent the drum nut from being detached and loosened. Could.

본 발명에 의한 차량의 휠 및 드럼 고정용 스터드 볼트에 의하면, 휠 너트의 풀림 및 스터드 볼트의 파손을 방지하며, 휠 및 타이어의 교환 후 휠 너트의 조임시 드럼너트가 이탈되지 않으며, 주행 중에 끊임없는 반복 인장, 압축 및 전단력에 의해서도 드럼너트의 풀림 및 유동이 발생하지 않아서, 스터드 볼트가 파손됨을 방지할 뿐만 아니라 타이어가 이탈로 인한 차량 전복등의 사고를 방지할 수 있어안전운행에 대한 신뢰성을 확보할 수 있다.According to the stud bolt for fixing the wheel of the vehicle and the drum according to the present invention, the wheel nut is prevented from loosening and the stud bolt is damaged, and the drum nut is not detached when the wheel nut is tightened after replacing the wheel and tire, and is cut off while driving. The drum nut does not loosen or flow due to repeated tension, compression, or shear force, which prevents the stud bolt from being broken and prevents accidents such as overturning of the vehicle due to tire detachment. It can be secured.
