본 고안은 자동차의 조향을 부드럽게 작동시킬 수 있는 자동차용 파워스티어링(Power Steering) 유압제어밸브에 관한 것으로서 특히 유압제어밸브의 인풋샤프트에서 밸브바디가 경방향으로 회전됨을 방지하여 노이즈(NOISE) 발생을 줄일 수 있도록한 밸브바디 회전방지구조에 관한 것이다.The present invention relates to a power steering hydraulic control valve for a vehicle that can smoothly operate the steering of the vehicle. Especially, the noise is generated by preventing the rotation of the valve body in the radial direction in the input shaft of the hydraulic control valve. It relates to a valve body anti-rotation structure that can be reduced.
일반적으로 자동차용 파워스티어링 유압제어밸브는 피니온이 조립된 인풋샤프트의 외주연에 밸브바디를 설치하고 밸브바디의 외주연에는 각 포오트를 막아 주는 실링을 환설한다. 이때 상기 인풋샤프트와 밸브바디는 장부핀(Powelpin)에 의해 고정한다.In general, power steering hydraulic control valves for automobiles install a valve body on the outer circumference of the input shaft on which the pinion is assembled, and replace a sealing that blocks each port on the outer circumference of the valve body. At this time, the input shaft and the valve body is fixed by a dowel pin (Powelpin).
이와 같이 조립되는 유압제어밸브는 운전자가 스티어링휠의 회전시 유니버셜조인트로 연결된 유압제어밸브의 피니온이 회전되어 인풋샤프트와 밸브바디가 회전된다.The hydraulic control valve assembled as described above rotates the pinion of the hydraulic control valve connected to the universal joint when the driver rotates the steering wheel to rotate the input shaft and the valve body.
그리고, 상기 회전에 의해 인풋샤프트의 이지(Edge) 연마부분의 매칭에 의해 랙하우징의 실린더로 작동유가 공급되어 랙하우징 내측의 피니온기어에 치합되어 있는 랙바와 인너볼죠인트(Inner Ball Joint)에 의해 고,저속시 바퀴를 조향토록한 것이다.The rotation oil is supplied to the cylinder of the rack housing by matching the edge grinding portion of the input shaft to the rack bar and the inner ball joint engaged with the pinion gear inside the rack housing. By steering the wheel at high and low speeds.
이때 상기 스티어링휠 회전시 유로조절 인풋샤프트의 작동핀에 의해 고정된 밸브바디가 측방향으로는 O.1∼0.25mm 정도 유격을 가져야 되지만 경방향으로 밸브바디가 회전되는 유격은 "0 화시켜야 하는 것은 주지된 사실이다.At this time, when the steering wheel is rotated, the valve body fixed by the operation pin of the flow control input shaft should have a clearance of about 0.1 to 0.25 mm in the lateral direction, but the clearance in which the valve body is rotated in the radial direction should be zeroed. It is a well known fact.
그러나 종래의 유압제어밸브(51)는 제 3 도에서와 같이 피니온이 연결된 인풋샤프트(52)에 작동핀(54)을 압입고정한 상태에서 실링이 환설된 밸브바디(53)의 설치홈(55)에 끼워 고정하였다.However, in the conventional hydraulic control valve 51, as shown in FIG. ) And fixed.
이와 같이 조립고정되는 유압제어밸브(51)는 인풋샤프트(52)에 환봉으로된 작동핀(54)을 압입고정한 후 밸브바디(53)의 설치요홈(55)을 연마한 후 끼워야 하므로 설치요홈(5)의 연마과정에서 정밀도가 요구되는 실정이다.Since the hydraulic control valve 51 assembled and fixed as described above should be press-fitted and fixed to the input shaft 52 by the operation pin 54 of the round bar, the installation recess 55 of the valve body 53 should be fitted and then fitted into the installation recess ( Precision is required in the polishing process of 5).
이때 상기 설치요홈(55)이 작동핀(54) 보다 적을 때에는 끼움고정이 불가능하고 클때에는 일정거리 즉 l거리만큼의 유격이 발생되어 실차에서 경방향 유격으로 인한 노이즈가 발생되는 문제점이 야기되었다.At this time, when the installation groove 55 is smaller than the operation pin 54, the fitting is impossible, and when large, the clearance is generated by a certain distance, that is, the l distance, causing noise to be generated due to radial clearance in the vehicle.
본 고안은 상기한 종래의 제문제점을 해결하기 위하여 안출한 것으로서 본 고안의 그 주된 목적은 유압제어밸브의 인풋샤프트에 압입고정된 고정핀의 상부에 텐션홈을 형성하여 상광하협된 상태로 텐션력을 부여하여, 밸브바디의 설치 요홈에 긴밀히 접촉된 상태로 끼움고정하므로서 유격발생됨의 방지로 경방향 회동됨이 전혀 없고, 설치요홈의 정밀가공이 아니더라도 텐션력이 있는 고정핀에 호환성있게 결합하여 사용할 수 있는 것이 그 특징이다.The present invention has been made to solve the above-mentioned problems, the main purpose of the present invention is to form a tension groove on the top of the fixed pin fixed to the input shaft of the hydraulic control valve tension tension By fitting the valve body into the mounting groove of the valve body in close contact, it prevents the occurrence of play and there is no turning in the radial direction, and it can be used by being compatible with the fixing pin with tension force even if the installation groove is not precisely processed. It is a feature that can be.
상기의 목적을 달성할 수 있는 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When the present invention to achieve the above object will be described in detail by the accompanying drawings as follows.
제 1 도 및 제 2 도에서와 같이 자동차용 파워스티어링 유압제어밸브(1)는 피니온이 조립된 인풋샤프트(2)에 작동핀(4)을 압입고정한 상태에서 밸브바디(3)의 설치요홈(5)을 끼워 조립한다.As shown in FIGS. 1 and 2, the power steering hydraulic control valve 1 for automobiles is provided with an installation recess of the valve body 3 with the actuating pin 4 pressed against the input shaft 2 to which the pinion is assembled. Assemble (5).
이때 상기 작동핀(4)은 상측을 중앙하단까지 절개한 후 텐션홈(6)이 형성하여 양측으로 벌려 텐션력을 갖도록 상광하협되게 형성한 것이다.At this time, the operation pin (4) is formed to be inclined up and down so that the tension groove 6 is formed by cutting the upper side to the lower end of the center and spread to both sides.
이와 같이 구성된 본 고안의 유압제어밸브(1)는 피니온이 조립된 인풋샤프트(2)에 텐션홈(6)을 각진 작동핀(4)을 압입고정한다.The hydraulic control valve (1) of the present invention configured as described above press-fits and tightens the tension groove (6) to the input shaft (2) to which the pinion is assembled.
그리고 인풋샤프트(2)의 외주연으론 밸브바디(3)를 끼워 고정하되 밸브바디(3)의 설치요홈(5)이 인풋샤프트(2)의 작동핀(4)과 결합되는 상태로 끼운다.And the outer periphery of the input shaft (2) is fixed by inserting the valve body 3, but the mounting groove (5) of the valve body (3) is fitted in the state coupled with the operating pin (4) of the input shaft (2).
이때 상기 설치요흡(4)의 텐션홈(6) 삽입고정시 양측으로 상광하협되게 벌어진 작동핀(4) 상측이 오므라지는 상태로 텐션력을 부여받으면서 간편용이하게 억지끼움 고정되는 것이다.At this time, when the tension groove (6) of the installation urine (4) is fixed to the upper side of the operation pin (4) that is opened up and down to both sides when the fixing force is easily tightened while being given a tension force.
상기와 같이 고정된 본 고안은 운전자가 스티어휠을 회전할시 유압제어밸브(1)의 인풋샤프트(2)와, 밸브바디(3)는 밸브바디(3)의 설치요홈(5)에 작동핀(4)이 텐션홈(6)에 의해 부여받는 텐션력에 의해 유격을 흡수하므로서 노이즈 발생이 전혀 없게될 뿐만 아니라 조립작업이 매우 양호하게 되는 매우 유용한 고안이다.The present invention fixed as described above has an input shaft (2) of the hydraulic control valve (1) and the valve body (3) when the driver rotates the steering wheel, the operating pin in the installation groove (5) of the valve body (3) (4) By absorbing the play by the tension force imparted by the tension groove (6), not only no noise is generated but also the assembly work is very useful.
