본 발명은 자동차 파워 스티어링의 고압호스와 튜브 연결용 니플 조립체에 관한 것으로서 더욱 상세히는 니플과 결합된 고압호스에 높은 압력으로 오일이 통과 되더라도 고압호스가 니플에서 분리될 우려가 없어 오일의 누유를 효과적으로 방지할 수 있는 자동차 파워 스티어링의 고압호스와 튜브 연결용 니플 조립체를 제공하기 위한 것이다.The present invention relates to a nipple assembly for connecting a high-pressure hose and a tube of an automobile power steering, and more particularly, even if oil passes through the high-pressure hose coupled with the nipple at high pressure, there is no fear that the high-pressure hose is separated from the nipple, effectively preventing oil leakage An object of the present invention is to provide a nipple assembly for connecting a high-pressure hose and tube of an automobile power steering that can be prevented.

일반적으로 차량에는 차량을 조향하는 조향장치가 설치되는데 상기 조향장치는 차량 내부에 설치되어 운전자가 조작하는 스티어링 휠(steering wheel), 스티어링 휠과 연결되어 회전하는 스티어링 칼럼(steering column), 스티어링 칼럼과 연결되어 충돌 시 수축되는 인텀 샤프트(interm shaft), 그리고 스터어링 칼럼의 회전력을 차량의 조향력으로 변환시키는 스티어링 기어(steering gear) 장치를 포함한다.In general, a steering device for steering the vehicle is installed in a vehicle, and the steering device is installed inside the vehicle and operated by a driver, a steering column connected to the steering wheel to rotate, a steering column and It includes an interm shaft that is connected to contract in the event of a collision, and a steering gear device that converts the rotational force of the steering column into steering force of the vehicle.

그런데 근래에는 저압 타이어의 사용과 차량의 대형화로 인하여 휠의 접지저항이 커지면서 스티어링 휠을 조작 시 특히 정지 시 또는 저속 운행 시 스티어링을 조작하기 힘들기 때문에 적은 힘으로도 큰 조향력을 발생할 수 있는 파워 스티어링 장치가 사용된다. However, in recent years, due to the use of low-pressure tires and the size of the vehicle, the ground resistance of the wheel increases and it is difficult to operate the steering wheel when operating the steering wheel, especially when stopping or driving at low speed. device is used.

파워 스티어링 장치는 조향장치에 유압으로 작동되는 파워실린더를 설치하여 조향을 용이하게 하는 것으로 즉, 파워실린더와 오일을 공급하는 스티어링 펌프, 오일의 양을 조절하는 유량조절밸브를 포함하여 파워실린더의 힘으로 스티어링 기어장치를 작동시켜 조향력을 더 크게 함으로써 조향을 용이하게 할 수 있다.The power steering device facilitates steering by installing a hydraulically operated power cylinder in the steering device. It is possible to facilitate steering by operating the steering gear device to increase the steering force.

즉, 스티어링 펌프에서 발생된 오일이 고압호스를 통하여 기어박스의 제어밸브로 공급되어 조향 시 조작력을 보조하여 주고, 제어밸브에서 동작을 완료한 오일은 고압호스를 통해 리저버탱크로 리턴하고 다시 고압호스를 통하여 스티어링 펌프로 공급되는 것으로서 오일을 공급하는 고압호스는 기밀성이 유지되어야 한다.That is, the oil generated from the steering pump is supplied to the control valve of the gearbox through the high-pressure hose to support the operation force during steering. The high-pressure hose that supplies oil as it is supplied to the steering pump through the

상기 고압호스 조립체의 선행기술이 대한민국특허청 등록특허 제620035호에 개시되어 있다.The prior art of the high-pressure hose assembly is disclosed in Korean Patent Office Registration No. 620035.

이와 같은 본 발명은 파워 스티어링 펌프로 펌핑된 오일을 스티어링 기어박스에 공급하기 위해 자동차 파워 스티어링의 고압호스와 튜브 연결용 니플 조립체를 구성함에 있어서, 튜브(100)의 선단이 플레어 너트(200)에 의해 밀폐되도록 내부에 끼워지는 니플머리부(310); 고압호스(400)가 외주면에 끼워지도록 니플머리부(310) 일측에 일정 길이로 돌출된 원통형의 니플몸체(320); 외주면에 끼워진 고압호스(400)의 미끄러짐 방지로 체결력을 높이기 위해 니플몸체(320) 외주면에 형성되는 다수 개의 그루부(321); 니플몸체(320)에 끼워진 부위의 고압호스(400) 외면을 감싸주어서 고압호스(400)의 선단이 니플몸체(320)에 밀착되게 하는 슬리브(500);로 구성된다.In the present invention, in configuring the nipple assembly for connecting the high-pressure hose and the tube of the automobile power steering to supply the oil pumped by the power steering pump to the steering gearbox, the tip of the tube 100 is attached to the flare nut 200. a nipple head 310 fitted therein to be sealed by; a cylindrical nipple body 320 protruding at a predetermined length from one side of the nipple head 310 so that the high-pressure hose 400 is fitted on the outer circumferential surface; A plurality of grooves 321 formed on the outer circumferential surface of the nipple body 320 to increase the fastening force by preventing the high-pressure hose 400 fitted into the outer circumferential surface from slipping; It is composed of a;

이러한 본 발명은 파워 스티어링 장치에서 일단은 파워 스티어링 펌프에 결합되고 타단은 스티어링 기어박스에 결합된 튜브(100)로 오일이 통과 시 발생되는 노이즈 감쇄를 위해 튜브(100)에 노이즈 감쇄용 고압호스(400)를 결합하되 튜브(100)에 고압호스(400)를 바로 연결하면 체결력이 떨어져 오일이 누유될 우려가 있기 때문에 니플을 구비하여 일단은 튜브(100)와 연결하고 타단은 고압호스(400)에 연결되게 하여 유압 노이즈를 감쇄시키도록 한 것은 종래와 마찬가지이다.In this invention, in the power steering device, a high-pressure hose for noise attenuation ( 400), but if the high-pressure hose 400 is directly connected to the tube 100, since the tightening force is lowered and there is a risk of oil leakage, one end is connected to the tube 100 and the other end is the high-pressure hose 400 It is the same as in the prior art to reduce hydraulic noise by connecting to the

그러나 본 발명에서의 특징은 니플과 고압호스(400)의 체결력을 향상시켜 오일이 높은 압력으로 고압호스(400)를 통과하더라도 니플몸체(320)에 끼워진 고압호스(400)가 니플몸체(320)에서 분리되는 일이 발생될 우려가 극히 적어 오일의 누유를 효과적으로 방지할 수 있는 것이다. However, the feature in the present invention is to improve the fastening force between the nipple and the high-pressure hose 400 so that even if the oil passes through the high-pressure hose 400 at a high pressure, the high-pressure hose 400 fitted into the nipple body 320 is the nipple body 320 . It is possible to effectively prevent oil leakage as there is very little risk of separation from the oil.

즉, 본 발명에서는 니플의 니플머리부(310)로는 튜브(100)의 선단을 끼우되 플레어 너트(200)에 의해 튜브(100)가 니플머리부(310)와 밀폐된 상태로 끼워지게 하고 니플몸체(320)에는 고압호스(400)가 끼워지게 한다.That is, in the present invention, the tip of the tube 100 is inserted into the nipple head 310 of the nipple, and the tube 100 is fitted in a sealed state with the nipple head 310 by the flare nut 200, and the nipple A high-pressure hose 400 is fitted to the body 320 .

여기서 니플몸체(320)의 외주면에는 다수개의 그루부(321)가 구비되어 니플몸체(320)에 고압호스(400)를 끼우면 그루부(321)가 고무재질의 고압호스(400)의 내주면에 밀착되면서 파고들어 니플몸체(320)와 고압호스(400)의 체결력을 향상시키고, 상기 니플몸체(320)에 끼워진 고압호스(400)에는 슬리브(500)로 고압호스(400)의 외면을 감싸주어서 니플몸체(320)에 결합된 고압호스(400)의 선단이 니플몸체(320)에 밀착되게 한다.Here, a plurality of grooves 321 are provided on the outer circumferential surface of the nipple body 320, and when the high-pressure hose 400 is inserted into the nipple body 320, the groove 321 is in close contact with the inner circumferential surface of the high-pressure hose 400 made of rubber. The nipple body 320 and the high-pressure hose 400 are tightened by digging in to improve the fastening force, and the high-pressure hose 400 fitted into the nipple body 320 has a sleeve 500 to wrap the outer surface of the high-pressure hose 400, so that the nipple The tip of the high-pressure hose 400 coupled to the body 320 is brought into close contact with the nipple body 320 .

그리고 상기 고압호스(400)의 선단 일부위에는 다른부위보다 두툼한 후육부(410)를 구비하고 고압호스(400)가 끼워지는 니플몸체(320)에는 상기 후육부(410)와 일치되는 부위에 상기 후육부(410)를 받쳐주는 볼록한 만곡부(322)를 형성하였다.And on a portion of the tip of the high-pressure hose 400, a thicker portion 410 than other portions is provided, and the nipple body 320 into which the high-pressure hose 400 is fitted has the thick portion 410 and the matching portion after the above. A convex curved portion 322 supporting the flesh portion 410 was formed.

즉, 도 2에서와 같이 니플몸체(320)에 고압호스(400)를 끼우게 되면 만곡부(322)가 고압호스(400)의 일부위를 밀어 고압호스(400)의 일부위가 밀려나가게 되는 것이고, 이에 슬리브(500)를 고압호스(400)에 끼우게 되면 고압호스(400)의 밀려난 부위에 구비된 후육부(410)가 슬리브(500)의 일부위를 밀면서 밀착되어 고압호스(400)와 니플몸체(320)의 체결력이 더욱 향상된다.That is, when the high-pressure hose 400 is inserted into the nipple body 320 as shown in FIG. 2 , the curved part 322 pushes a part of the high-pressure hose 400 and a part of the high-pressure hose 400 is pushed out. , when the sleeve 500 is inserted into the high-pressure hose 400, the thick part 410 provided in the pushed out portion of the high-pressure hose 400 is in close contact while pushing a part of the sleeve 500 to the high-pressure hose 400 And the fastening force of the nipple body 320 is further improved.

따라서 스티어링 펌프에 의해 펌핑된 오일이 압력이 높은 상태에서 고압호스(400)를 통과하더라도 니플몸체(320)에 끼워진 고압호스(400)가 니플몸체(320)에서 분리되는 일이 발생되지 않는 것이다.Therefore, even if the oil pumped by the steering pump passes through the high-pressure hose 400 in a high pressure state, the high-pressure hose 400 fitted into the nipple body 320 does not separate from the nipple body 320 It does not occur.

또한, 본 발명에서는 니플몸체(320)에 끼워지는 부위의 고압호스(400)의 외주면에 체결돌기(420)를 다수 형성하였기 때문에 슬리브(500)를 고압호스(400)에 끼워주게 되면 체결돌기(420)가 슬리브(500)의 내주연에 밀착되면서 파고들어가 고압호스(400)와 슬리브(500)의 체결력이 향상되면서 고압호스(400)와 니플몸체(320)의 체결력 또한 향상되게 된다.In addition, in the present invention, since a large number of fastening protrusions 420 are formed on the outer circumferential surface of the high-pressure hose 400 at the portion to be fitted into the nipple body 320, when the sleeve 500 is inserted into the high-pressure hose 400, the fastening protrusion ( As the 420 is in close contact with the inner periphery of the sleeve 500, the fastening force between the high-pressure hose 400 and the sleeve 500 is improved, and the fastening force between the high-pressure hose 400 and the nipple body 320 is also improved.

그리고 상기 니플몸체(320)에는 그루부(321)와 니플머리부(310) 사이 일정거리의 이격부위에 스톱퍼(323)를 형성한 것으로 이는 고압호스(400)의 선단을 니플몸체(320)에 끼운후 고압호스(400)를 니플머리부(310) 방향으로 계속해서 밀어주면 고압호스(400)의 선단이 스톱퍼(323)에 접면되면서 더이상 전진되지 못하게 되는 것으로 고압호스(400)의 조립상태를 항상 일정하도록 한 것이다.And in the nipple body 320, a stopper 323 is formed in a portion spaced at a predetermined distance between the groove 321 and the nipple head 310, which connects the tip of the high-pressure hose 400 to the nipple body 320. When the high-pressure hose 400 is continuously pushed in the direction of the nipple head 310 after insertion, the tip of the high-pressure hose 400 contacts the stopper 323 and cannot advance any more. It was always set to be constant.
