파워스티어링 펌프용 리테이너 링{Retainer ring used for power steering pump}Retainer ring used for power steering pump

본 발명은 파워스티어링 펌프용 리테이너 링에 관한 것으로서, 특히 밀착성과 내진성이 높으며 전용공구를 사용하지 않고 조립 및 분해를 간단 용이하게 할 수 있도록 한 것이다.The present invention relates to a retainer ring for a power steering pump, and in particular, has high adhesion and shock resistance, and enables easy assembly and disassembly without using a dedicated tool.

일반적으로 파워스티어링 기어는 차량의 대형화 및 저압 타이어의 사용에 의한 앞바퀴의 접지저항이 커져 스티어링 휠의 조작이 어려워짐에 따라 조향 조작력이 증대되기 때문에 신속한 조향 조작이 곤란하게 되어 가볍고 원활한 조향조작을 하기 위한 것이다.In general, the power steering gear has a large ground resistance of the front wheel due to the size of the vehicle and the use of low-pressure tires, which makes steering steering difficult as the steering wheel becomes difficult to operate. It is for.

엔진의 동력으로 유압펌프를 구동함으로써 발생되는 유압을 이용하여 조향 휠의 조작력을 가볍게 하기 위한 장치로서, 파워스티어링 기어의 특징은 조향 조작력에 관계없이 조향 기어비를 선정할 수 있으며, 노면의 충격을 흡수하여 스티어링 휠에 전달되는 것을 방지 할 뿐 아니라, 앞바퀴의 모션을 감쇠하며 차량의 안전운전을 도모한다.A device for lightening the steering wheel's operating force by using the hydraulic pressure generated by driving the hydraulic pump by the power of the engine. The characteristic of the power steering gear is to select the steering gear ratio regardless of the steering operation force and to absorb the impact of the road surface. In addition to preventing transmission to the steering wheel, it also attenuates the motion of the front wheels and promotes safe driving of the vehicle.

이러한 기능을 갖는 파워스티어링 기어는 운전자가 조향조작이 직접 전달되는 스티어링 휠과 조향축 및 스티어링 컬럼으로 구성되는 조작기구와, 조향축의 회전을 감속함으로써 조작력을 증대시켜줌과 동시에 조작기구의 운동방향을 바꾸어 링크기구에 전달하는 밸브 하우징부 및 랙 하우징부로 구성되는 기어부와, 조향력을 앞바퀴에 직접 전달함과 동시에 좌우 바퀴의 관계위치를 올바르게 유지하는 너클 암 및 타이로드 등으로 구성되는 링크기구부가 있다.The power steering gear with this function allows the driver to control the steering wheel, which is directly transmitted by the steering operation, the steering shaft and the steering column, and increase the operating force by reducing the rotation of the steering shaft, and at the same time change the direction of the operation mechanism. There is a gear part composed of a valve housing part and a rack housing part for transmitting to the link mechanism, and a link mechanism part composed of a knuckle arm and a tie rod which directly transmits steering force to the front wheel and at the same time correctly maintains the relationship between the left and right wheels.

상기의 기어부에는 조향조작력의 증대를 위해 유압펌프에 의한 유압의 작용을 통해 랙하우징내의 랙바에 체결된 실린더를 중심으로 양측 공간에 유압의 차이를 가지게 함과 동시에, 밸브하우징내의 랙과 피니언이 같이 작동함으로써 보다 용이한 핸들 조작을 이루도록 하는 것이다.The gear unit has a hydraulic pressure difference in both spaces around the cylinder fastened to the rack bar in the rack housing through the action of hydraulic pressure by the hydraulic pump to increase steering operation force, and at the same time the rack and pinion in the valve housing By working together, it is easier to handle.

여기에서, 상기 유압펌프는 외부로부터의 회전력을 이용하여 하우징 내부에구비된 베인을 고속으로 회전시켜 필요한 오일의 압력을 얻도록 구비되어 있다.Here, the hydraulic pump is provided to rotate the vane provided inside the housing at a high speed by using the rotational force from the outside to obtain the required oil pressure.

이러한 회전력을 얻기 위해 펌프 하우징의 내부에는 드라이버 샤프트를 중심으로 모든 부품유닛이 회전 가능하게 구비되어 있으며, 내부로 유입된 오일이 외부로 누출되는 것을 방지하도록 기밀유지가 되어 있다.In order to obtain such rotational force, all the component units are rotatably provided around the driver shaft in the pump housing, and are kept airtight to prevent oil introduced into the outside from leaking to the outside.

또한, 드라이버 샤프트는 양측에 베어링을 개재하여 하우징 내부에서 회전할 수 있도록 구비되어 있으며, 드라이버 샤프트와 베어링의 축방향의 이동을 제한하기 위한 수단을 통상의 리테이너 링이 개재되어 있다.In addition, the driver shaft is provided so as to rotate inside the housing via the bearing on both sides, and the usual retainer ring is provided to limit the axial movement of the driver shaft and the bearing.

이러한 리테이너 링은 도 1 내지 도 3에 도시된 바와 같이, 스냅링(10)이나 리테이너 링(20)을 사용하며, 이러한 스냅링(10)이나 리테이너 링(20)의 장점을 살린 복합 구조용 리테이너 링(30)을 사용하고 있으나, 리테이너 링을 고정하기 위해서는 전용공구를 사용해야 하는 불편한 문제점이 있었다.As shown in FIGS. 1 to 3, the retainer ring uses a snap ring 10 or a retainer ring 20, and a composite structural retainer ring 30 utilizing the advantages of the snap ring 10 or the retainer ring 20. However, in order to fix the retainer ring, there was an uncomfortable problem of using a dedicated tool.

또한, 리테이너 링을 정밀하게 가공토록 함으로써, 그 효율이 낮아지는 또 다른 문제점이 있었다.In addition, by precisely processing the retainer ring, there is another problem that the efficiency is lowered.

본 발명은 이와 같은 문제점을 해소하기 위해 안출한 것으로서, 밀착성과 내진성이 높으며 전용공구를 사용하지 않고 조립 및 분해를 간단용이 하게 할 수 있는 파워스티어링 펌프용 리테이너 링을 제공하는데 그 목적이 있다.The present invention has been made in order to solve such a problem, the object of the present invention is to provide a retainer ring for power steering pump that has high adhesion and shock resistance, and can easily assemble and disassemble without using a dedicated tool.

이와 같은 목적을 달성하기 위해 본 발명은 드라이버 샤프트에 베어링을 고정하는 파워스티어링 펌프용 리테이너 링에 있어서, 상기 리테이너 링은 드라이버샤프트와 펌프 하우징 사이에 개재되어 양측방향으로 소정의 반발력이 작용하도록 중앙부를 전면으로 절곡시킨 상태로 구비하고, 상하 양단은 만곡형의 형태로 구비하되, 상부가 개방된 형태로 구비하고, 좌우 양측이 수직으로 형성되도록 구성됨을 특징으로 하는 파워스티어링 펌프용 리테이너 링을 제공한다.In order to achieve the above object, the present invention provides a retainer ring for a power steering pump for fixing a bearing to a driver shaft, wherein the retainer ring is interposed between the driver shaft and the pump housing so that a predetermined reaction force acts in both directions. It is provided in a state bent to the front, and the upper and lower ends are provided in a curved form, the upper portion is provided in an open form, and provides a retainer ring for the power steering pump, characterized in that the left and right sides are configured to be formed vertically. .

이하, 본 발명의 실시예를 첨부 도면을 참조하여 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

본 발명에 따른 파워스티어링 펌프용 리테이너 링은 도 4에 도면번호 40으로 도시된 바와 같이, 드라이버 샤프트와 펌프 하우징 사이에 개재되어 양측방향으로 소정의 반발력이 작용하도록 중앙부가 전면으로 절곡된 상태로 구비되어 있다.Retainer ring for the power steering pump according to the present invention is shown in Figure 4, the reference numeral 40, it is provided between the driver shaft and the pump housing in a state in which the center portion is bent to the front to act a predetermined reaction force in both directions It is.

또한, 그 상하 양단은 만곡형의 형태로 구비하되, 상부가 개방된 형태로 구비하고, 좌우 양측이 수직으로 형성되도록 구성되어 있다.In addition, the upper and lower ends are provided in the form of a curved shape, the upper portion is provided in an open form, and is configured so that both left and right sides are formed vertically.

이와 같은 구성을 갖는 파워스티어링 펌프용 리테이너 링은 조립 및 해체 작업 시 별도의 공구를 이용하지 않고 간단히 드라이브 샤프트에 끼워 넣는 것으로서 그 조립작업이 마무리 된다.The retainer ring for the power steering pump having such a configuration is simply inserted into the drive shaft without the use of a separate tool during assembly and dismantling, thereby completing the assembly work.

그리고, 이렇게 리테이너 링이 삽입된 상태로 펌프하우징 내에 설치할 경우, 그 탄성력에 의해 밀착되어 있음으로써, 유격이 감소되거나 이로 인한 오일의 압력에 변화가 발생되는 것을 사전에 막을 수 있게 된다.When the retainer ring is installed in the pump housing in such a state that the retainer ring is inserted in this manner, the retaining ring is in close contact with the elastic force, thereby preventing the play from being reduced or a change in the pressure of the oil.

이상에서 살펴 본 바와 같이, 본 발명은 리테이너 링의 가장자리가 중심을 기준으로 전방으로 소정의 각도를 갖도록 절곡되어져 구성됨으로써, 별도의 전용공구를 이용하지 않고 조립 및 분해가 가능하게 한 것이다.As described above, the present invention is configured so that the edge of the retainer ring is bent to have a predetermined angle forward with respect to the center, thereby assembling and disassembling without using a separate dedicated tool.
