Description
본 발명은 자동차용 조향장치의 랙바용 서포트 요크의 간격 측정구조에 대한 것으로서, 더 상세하게는 랙바의 유동에 영향을 주는 서포트 요크의 간격을 직접측정할 수 있도록 한 것이다.The present invention relates to a gap measuring structure of the support yoke for the rack bar of the steering apparatus for automobiles, and more particularly, to directly measure the gap of the support yoke affecting the flow of the rack bar.
일반적으로 자동차용 조향장치는 상단에 조향핸들이 축착된 조향축과, 조향축의 하단에 연결된 피니언축(1)과, 피니언이 치합된 랙바와, 랙바의 좌, 우 양측에 연결되는 이너볼 조인트 및 아우트 볼 조인트로써 차륜까지 연결되어 있다.In general, a vehicle steering device includes a steering shaft in which a steering wheel is constricted on the top, a pinion shaft (1) connected to a lower end of the steering shaft, a rack bar in which the pinion is engaged, an inner ball joint connected to both left and right sides of the rack bar, and It is connected to the wheel by the outer ball joint.
그리고 상기한 피니언축(1)의 피니언(11)과 랙바(2)의 랙(21)은 하우징(9)의 속에서 치합되도록 하되, 랙바(2)의 뒤에 서포트 요크(3)를 밀착시켜 매우 긴밀한 상태를 유지하도록 조립되어 있다.The pinion 11 of the pinion shaft 1 and the rack 21 of the rack bar 2 are to be engaged in the housing 9, but the support yoke 3 is closely attached to the rear of the rack bar 2 so as to be in close contact with each other. It is assembled to maintain a close state.
즉, 피니언축(1)의 피니언(11)과 랙바(2)의 랙(21)이 가장 양호한 상태로 밀착되어 있어야만 보다 정확한 동력전달이 가능한 바, 밀착정도가 약하면 회전 토오크값이 작아지는 반면, 치합상태가 불량해지며, 밀착정도가 강하면 치합상태가 좋은 반면, 회전 토오크값이 커지기 때문에 조작이 힘들어진다.That is, the pinion 11 of the pinion shaft 1 and the rack 21 of the rack bar 2 should be in close contact with each other in the best state, so that more accurate power transmission is possible. The engagement state is poor, and the tightness is good, the engagement state is good, but the operation is difficult because the rotation torque value increases.
이와 같이 서포트 요크(3)의 밀착정도를 조절하기 위한 종래의 방법을 보면, 서포트 요크(3)의 후방으로 서포트 요크의 긴밀도를 조절하기 위한 압축코일스프링(5)과, 압축코일스프링(5)의 이탈을 막기 위해 나사 조립한 요크 플러그(4)로 구성한 후, 상기의 요크 플러그(4)를 깊게 또는 얕게 나삽하므로써 압축코일스프링(5)의 탄성이 서포트 요크(3)를 강하게 또는 약하게 밀어주게 되는 것이다.As described above, in the conventional method for adjusting the adhesion of the support yoke 3, the compression coil spring 5 and the compression coil spring 5 for adjusting the long density of the support yoke to the rear of the support yoke 3 are provided. After the yoke plug 4 is screw-assembled to prevent separation, the elasticity of the compression coil spring 5 strongly or weakly pushes the support yoke 3 by inserting the yoke plug 4 deeply or shallowly. Will be given.
그리고 통상적으로 서포트 요크(3)의 밀착 정도는 서포트 요크(3)와 요크 플러그(4) 사이의 간격(P)으로 판단하며, 이는 압축코일스프링(5)의 탄성계수가 미리 정해져 있기 때문에 가능하다.In general, the degree of adhesion of the support yoke 3 is determined by the distance P between the support yoke 3 and the yoke plug 4, which is possible because the elasticity coefficient of the compression coil spring 5 is predetermined. .
그러나 이와 같은 종래의 구조에서는 서포트 요크(3)와 요크 플러그(4) 사이의 간격(P)을 측정하기 위해서 별도의 특수한 측정지그가 필요할 뿐만 아니라 간격(P)을 측정한 후에는 재차 조립하여야 하는 불편이 있다.However, in such a conventional structure, not only a special measuring jig is required to measure the gap P between the support yoke 3 and the yoke plug 4, but also the inconvenience of having to reassemble it after measuring the gap P. There is this.
따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 안출한 것으로서, 발명의 주된 목적은 요크 플러그의 구조를 새로이 형성하므로서 별도의 측정지그를 사용하지 않고도 서포트 요크와 요크 플러그 사이의 간격을 측정할 수 있도록 하는데 있으며, 또 한편으로는 간격을 측정하면서 요크 플러그를 나삽할 수 있도록 하는데 있는 것이다.Therefore, the present invention has been made in view of the above-mentioned conventional problems to solve the problem, the main object of the invention is to form a structure of the yoke plug newly, so that the gap between the support yoke and the yoke plug without using a separate measuring jig To allow the yoke plug to be inserted while measuring the gap.
이를 위한 특징적인 수단은 상단에 조향핸들이 축착되는 조향축 하단의 피니언과, 좌, 우 양측의 볼 조인트로써 차륜까지 연결하도록 구성된 랙바의 랙을 하우징의 내부에서 치합시키되, 랙바의 후방에 접하는 서포트 요크와, 서포트 요크의 후방에 탄설된 압축코일스프링과, 압축코일스프링의 탄성을 조절할 수 있도록 나삽한 요크 플러그로 이루어진 자동차용 조향장치에 있어서, 상기한 요크 플러그는 중공부를 갖는 용기타입으로 형성하되, 그 바닥의 중앙에 통공을 형성하고, 그 내부에 스프링과, 돌기부를 갖는 측정판과, 수밀성 고무판을 차례로 내장시키되, 돌기부는 스프링을 지나 상기한 통공속으로 끼워지도록 하고, 수밀성 고무판은 탄성지지력을 갖는 환테부가 중공부의 내경에 끼워지도록 조립하므로써 상기한 측정판이 눌렸을 때 그 돌기가 간격을 측정할 수 있도록 하는데 있다.A characteristic means for this is to support the pinion at the bottom of the steering shaft, which is steered by the steering wheel at the top, and the rack of the rack bar configured to connect to the wheels as ball joints on both the left and right sides, inside the housing, while supporting the rear of the rack bar.

이때, 본 발명에서는 상기한 요크 플러그(4)를 중공부(41)를 갖는 용기타입으로 형성하되, 그 바닥의 중앙에 통공(42)을 형성하고, 그 내부에 스프링(7)과, 돌기부(61)를 갖는 측정판(6)과, 수밀성 고무판(8)을 차례로 내장시키되, 돌기부(61)는 스프링을 지나 상기한 통공(42)속으로 끼워지도록 하고, 수밀성 고무판(8)은 탄성지지력을 갖는 환테부(81)가 중공부(41)의 내경에 끼워 조립하는데 특징이 있는 것이다.At this time, in the present invention, the yoke plug 4 is formed in a container type having a hollow portion 41, but a through hole 42 is formed in the center of the bottom thereof, and a spring 7 and a protrusion ( A measuring plate 6 having a 61 and a watertight rubber plate 8 are sequentially installed, and the protrusions 61 are inserted through the spring into the above-described through holes 42, and the watertight rubber plate 8 has elastic support force. It is characterized in that the annular portion 81 having a fitting fitted to the inner diameter of the hollow portion 41.
그리고 상기한 요크 플러그(4)에 측정판(6)을 조립하기 위해서는 그 중공부(41)의 내주면에 복수의 돌기(43)를 형성하고, 측정판(6)에는 복수의 요홈(62)을 형성하여, 돌기(43)의 위치가 요홈(62)의 위치와 일치하도록 맞추어 끼운 후, 돌렸을 때 뒤로 후퇴되지 않도록 한다.In order to assemble the measuring plate 6 to the yoke plug 4, a plurality of protrusions 43 are formed on the inner circumferential surface of the hollow part 41, and the plurality of grooves 62 are provided on the measuring plate 6. It is formed so as to fit the position of the projection 43 to match the position of the groove 62, so as not to retreat backward when turned.
이와 같이 구성된 본 발명은 하우징(9)의 내부에 랙바(2)의 뒷면을 받치는 서포트 요크(3)를 끼우고, 그 다음으로 압축코일스프링(5)을 끼우며, 상기 압축코일스프링(5)을 압축할 수 있는 본 발명의 요크 플러그(4)를 나삽한다.According to the present invention configured as described above, the support yoke 3 supporting the rear of the rack bar 2 is inserted into the housing 9, and then the compression coil spring 5 is inserted into the compression coil spring 5. The yoke plug 4 of the present invention capable of compressing is inserted.
이때, 본 발명의 요크 플러그(4)는 내부에 스프링(7)에 탄설된 측정판(6)이 설치되어 있는 것으로서,At this time, the yoke plug 4 of the present invention is provided with a measuring plate 6 installed on the spring 7 therein,
요크 플러그(4)를 나삽할 때, 깊이 측정기(M)로써 측정판(6)을 밀어 넣으면 측정판(6)은 스프링(7)을 누르고 들어가게 되고, 이 측정판(6)의 돌기부(61)가 통공(42) 안쪽의 서포트 요크(3)면에 닿으면 정지한다.When the yoke plug 4 is screwed in, the measuring plate 6 is pushed into the measuring plate 6 by pressing the depth measuring member M, and the projection 61 of the measuring plate 6 is pushed in.
