Description
본 고안은 자동차의 현가장치용 볼조인트의 구조에 관한 것으로, 특히 볼조인트의 스터드부위의 형상을 변경시켜 강성을 보강시킴으로써 부품의 파손을 방지하면서 내구성을 향상시킬 수 있도록 된 자동차의 현가장치용 볼조인트의 구조에 관한 것이다.The present invention relates to a structure of a ball joint for a suspension device of an automobile, and in particular, by changing the shape of the stud portion of the ball joint to reinforce rigidity, a ball for a suspension device of an automobile that can improve durability while preventing damage to parts. It relates to the structure of the joint.
일반적으로 자동차의 현가장치에서 차체프레임의 양선단부위에 결합되는 어퍼 또는 로우아암의 선단부와, 너클의 선단부는 각기 볼조인트를 매개로 결합되어 주행중 이들 부품들간의 상대운동이 원활하게 이루어질 수 있도록 되어 있다.In general, in the suspension of a vehicle, the upper or lower arm tip and the knuckle tip are coupled to both ends of the body frame, and the knuckles are respectively connected through a ball joint so that relative movement between these parts can be performed smoothly while driving. .
즉 도 1과 도 2에 각기 도시된 바와 같이, 너클(11)의 선단부위에 관통되게 형성된 원형의 개구부(11a)내로 볼조인트(12)의 스터드(12a)가 삽입되면서 이의 선단부위가 너트(13)를 매개로 고정되도록 체결되고, 상기 볼조인트(12)의 하부 볼부위(12b)가 아암(도시안됨)의 선단부위에 안착되어져, 주행시 상기 너클(11)과 아암이 볼조인트(12)를 매개로 상대운동 가능하도록 되어 있다.That is, as shown in FIGS. 1 and 2, the studs 12a of the ball joint 12 are inserted into the circular openings 11a formed to penetrate the tips of the knuckles 11, and the tips thereof are the nuts 13. And the lower ball portion 12b of the ball joint 12 is seated on the tip portion of the arm (not shown), so that the knuckle 11 and the arm mediate the ball joint 12 during driving. Relative movement is possible.
여기서 상기 너클(11)의 개구부(11a)에 삽입되어 체결되는 볼조인트(12)의 스터드부(12a)는 개구부(11a)내로의 삽입이 용이하도록 테이퍼지도록 형성되어 있으며, 이 테어퍼진 스터드부(12a)의 선단부위에는 나사가공이 되어져, 이 부위로 너트(13)가 규정된 토오크로 체결되도록 되어 있다.Here, the stud portion 12a of the ball joint 12 inserted into and fastened to the opening 11a of the knuckle 11 is formed to be tapered to facilitate insertion into the opening 11a, and the tapered stud portion ( The tip end portion of 12a) is threaded so that the nut 13 is tightened to the prescribed torque.
또한 상기 볼조인트(12)의 하단부위는 기밀유지를 위해 커버(14)에 의해 밀봉되게 감싸여져 있으며 하단 볼부위(12b)는 아암의 선단부위와 결합되는 케이스(15)내에 내장되어 있다.In addition, the lower end of the ball joint 12 is enclosed by the cover 14 for hermetic sealing, and the lower ball 12b is embedded in the case 15 coupled with the tip of the arm.
그런데 상기와 같은 구조의 볼조인트를 매개로 너클과 아암을 결합시키는 종래의 자동차 현가장치에서는 주행중 차륜의 상하운동으로 인해 볼조인트의 스터드부가 차량의 좌우방향으로 굽어지려는 굽힘모멘트를 받게 된다.However, in the conventional vehicle suspension system in which the knuckle and the arm are coupled through the ball joint having the structure as described above, the stud portion of the ball joint receives a bending moment due to the vertical movement of the wheel while driving.
따라서 상기 볼조인트의 스터드부위에서는 경우에 차륜이 받는 하중의 수배까지의 하중을 받게 되므로 극단적인 경우 볼조인트의 스터드부위가 과도한 굽힘모멘트의 영향으로 파단되는 문제점이 있었다.Therefore, in the case of the stud portion of the ball joint is subjected to the load up to several times the load received in the case, in the extreme case there was a problem that the stud portion of the ball joint is broken by the influence of excessive bending moment.
이에 본 고안은 상기한 문제점을 해결하기 위해 안출된 것으로, 볼조인트의 스터드부위를 주행중 좌우방향으로 받는 굽힘모멘트에 견딜 수 있도록 강성을 보강시켜 차륜의 상하운동 및 횡하중 작용시 파단을 방지할 수 있을 뿐만 아니라 차량의 안정성 향상에도 기여할 수 있도록 된 자동차의 현가장치용 볼조인트의 구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, by reinforcing the rigidity to withstand the bending moment received in the left and right direction while driving the stud portion of the ball joint to prevent breakage during the vertical movement and lateral load of the wheel In addition, the object of the present invention is to provide a structure of a ball joint for suspension of a vehicle that can contribute to improving the stability of the vehicle.

상기한 바의 목적을 달성하기 위한 본 고안은, 볼조인트의 상측 스터드부위가 직선화된 환봉형상으로 이루여져 강성이 보강되도록 형성되면서 하단부의 양측부에는 좌우로 길게 연장된 돌출부를 일체로 형성하여 차륜의 횡하중 작용시 스터드부위에 가해지는 굽힘모멘트에 대한 강성을 향상시킬 수 있도록 된 구조로 되어 있다.The present invention for achieving the above object is, the upper stud portion of the ball joint is formed in a straight round bar shape is formed so as to reinforce the rigidity formed on both sides of the lower end integrally extending protrusions left and right wheels It is designed to improve the rigidity against bending moment applied to the stud part during the lateral load action.
이하 본 고안의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 3는 본 고안에 따른 현가장치용 볼조인트의 단면도이고, 도 4는 본 고안의 현가장치용 볼조인트의 스터드부위와 결합되는 아암선단부위의 평면도인 바, 즉 본 고안의 볼조인트(2)는 상부 스터드부(2a)가 직선화된 환봉형상으로 이루어지면서 하단부의 양측부는 좌우로 길게 연장된 돌출부(2b)를 일체로 형성한 구조로 되어 있다.Figure 3 is a cross-sectional view of the ball joint for the suspension device according to the present invention, Figure 4 is a plan view of the arm tip portion coupled to the stud portion of the ball joint for the suspension device of the present invention, that is, the ball joint (2) The upper stud portion 2a is formed in a straight rod shape, and both sides of the lower portion have a structure in which the protruding portions 2b extending to the left and right are integrally formed.
또한, 상기 볼조인트(2)의 스터드부(2a)가 삽입되는 너클(1)의 개구부(1a)양측부, 즉 차량의 좌우측 방향으로도 상기 스터드부(2a)의 양측 돌출부(2b)가 압입될 수 있도록 동일한 외형을 지닌 함몰부(1b)가 형성되어 있다.In addition, both sides of the opening portion 1a of the knuckle 1 into which the stud portion 2a of the ball joint 2 is inserted, that is, both projections 2b of the stud portion 2a in the left and right directions of the vehicle are press-fitted. The depression 1b having the same shape is formed so as to be possible.
이에 따라 종래 볼조인트(2)의 스터드부(2a)가 테이퍼진 형상으로 이루어짐에 따른 국부적인 강성약화가 크게 개선될 뿐만 아니라, 스터드부(2a)의 하단 양측부로 일체 형성된 돌출부(2b)는 타 부품에 스터드부(2a)가 체결될 때 이 스터드부(2a)가 너클(1)의 개구부(1a)에 삽입된 후 너트(도시안됨)에 의해 과다하게 조여져 체결될 경우에도 타부품으로 압입되어짐에 따른 현가장치에서 기하적인 조립위치가 변하게 되는 조립불량을 미연에 방지해 줄 수 있게 한다.As a result, not only the local rigidity weakening is greatly improved as the stud portion 2a of the conventional ball joint 2 has a tapered shape, and the protrusion 2b integrally formed at both sides of the lower end of the stud portion 2a is formed. When the stud part 2a is fastened to the part, the stud part 2a is inserted into the opening part 1a of the knuckle 1, and is pressed into other parts even if it is excessively tightened and tightened by a nut (not shown). It is possible to prevent the assembly failure that the geometric assembly position is changed in the suspension according to.
이상 설명한 바와 같이 본 고안에 따른 자동차의 현가장치용 볼조인트의 구조에 의하면, 현가장치에서 아암의 선단부위와 너클의 선단부위에 장착되어 상대부품간의 회전운동을 원활하게 해 주는 볼조인트의 스터드부위가 직선화된 환봉형상으로 이루어지면서 하단부의 양측부에는 좌우로 길게 연장된 돌출부를 일체로 형성함에 따라, 스터드부의 접촉표면적이 증대되어 주행중 차륜의 상하운동으로 차륜이 받는 하중의 수배까지의 굽힘모멘트에도 견딜 수 있는 강성을 확보할 수 있게 되어 부품의 내구성을 향상시킬 수 있게 되며, 또한 너클에 볼조인트의 스터드부가 체결될 때 너트에 의한 과도한 조임으로 인해 타 부품으로 압입되지 않게 되어 현가장치의 기하적인 조립위치가 변하게 되는 조립불량을 예방할 수 있는 효과가 있게 된다.As described above, according to the structure of the ball joint for the suspension device of the vehicle according to the present invention, the stud part of the ball joint is mounted on the leading end of the arm and the leading end of the knuckle in the suspension to smooth the rotational movement between the counterparts. As it is formed in the shape of a round bar, integrally extending protrusions extending from side to side on both sides of the lower end portion, the contact surface area of the stud is increased to withstand bending moments up to several times the load that the wheel receives due to the vertical movement of the wheel while driving. The rigidity of the suspension can be secured, and the durability of the parts can be improved. Also, when the stud part of the ball joint is fastened to the knuckle, it is not press-fitted into other parts due to excessive tightening by the nut. There is an effect to prevent the assembly failure to be changed.
