Description

동력조향장치의 유압펌프의 고압호스 회전방지장치High pressure hose anti-rotation device of hydraulic pump of power steering system

본 고안은 동력조향장치의 유압펌프에 관한 것으로서, 특히 고압호스를 유압펌프에 연결하기 위해 고압호스를 펌프바디에 보울트로 체결할 때에 고압호스가 회전되지 않도록 하여 고압호스의 장착작업이 용이하게 이루어질 수 있도록 된 동력조향장치의 유압펌프의 고압호스 회전방지장치에 관한 것이다.The present invention relates to a hydraulic pump of a power steering device, in particular, in order to connect the high pressure hose to the hydraulic pump to prevent the high pressure hose from rotating when the high pressure hose is bolted to the pump body to facilitate the installation of the high pressure hose. It relates to a high pressure hose anti-rotation device of the hydraulic pump of the power steering device.

일반적으로 자동차의 조향장치는 자동차의 진행방향을 임의로 바꾸기 위해 조향을 하는 장치로서, 운전자가 직접 조향조작을 하여 그 조작력을 조향기어 및 링크 등에 전달하기 위해 조향핸들과 조향축 및 칼럼 등으로 구성된 조작기구와, 상기 조향축의 회전을 감속하여 조작력을 크게 함과 동시에 조작기구의 운동방향을 바꾸어 링크기구에 전달하는 기어장치 및, 기어기구의 작동을 앞바퀴에 전달하고 또 좌우 바퀴의 관계위치를 바르게 지지하기 위해 피트먼 아암과 드래드 아암, 너클 아암 및 타이로드 등으로 구성된 링크기구로 이루어져 있다.In general, a steering device of a vehicle is a device for steering in order to arbitrarily change the driving direction of a vehicle, and the driver consists of steering handles, steering shafts, columns, and the like for direct steering to transfer steering power to steering gears and links. The gear and the gear unit to reduce the rotation of the steering shaft to increase the operating force and to change the direction of movement of the operating mechanism to the link mechanism, and to transmit the operation of the gear mechanism to the front wheels and to correctly support the relation positions of the left and right wheels. It consists of a link mechanism consisting of a pitman arm, a draft arm, a knuckle arm and a tie rod.

그리고 대형 자동차나 저압 타이어를 사용한 차량에서는 앞바퀴의 접지저항이 크기 때문에 핸들의 조작력이 크게 되고 신속한 조향 조작이 안될 염려가 있기 때문에 가볍고 신속한 조향조작을 하기 위해 동력조향장치를 사용하고 있는 바, 이와 같은 동력조향장치는 동력원이 되는 유압을 발생시키는 유압펌프와 압력조절밸브 및 유량제어밸브를 포함하는 밸브 유닛 등으로 구성된 동력장치와, 상기 오일펌프에서 발생한 유압을 기계적인 힘으로 바꾸어 조향력을 발생시키기 위해 실린더를 사용하는 작동장치 및, 이 작동장치에 이르는 유로를 개폐하고 핸들의 조작에 상응해서 유로를 바꾸어 동력실린더의 작동방향과 작동상태를 제어하는 제어장치 등으로 구성되어 있다.In the case of a large vehicle or a vehicle using low pressure tires, since the grounding resistance of the front wheel is large, the steering force of the steering wheel becomes large and the quick steering operation is not possible. Therefore, the power steering device is used for light and quick steering operation. The power steering device includes a power device including a hydraulic pump for generating hydraulic pressure as a power source, a valve unit including a pressure control valve and a flow control valve, and a hydraulic force generated by the oil pump to generate a steering force. An operating device using a cylinder and a control device for opening and closing the flow path leading to the operation device and controlling the operation direction and operating state of the power cylinder by changing the flow path in accordance with the operation of the handle.

여기서 상기 유압펌프는 펌프바디와 펌프축, 로터, 베인, 캠링 및 베어링 등으로 구성되어 있고, 안쪽 벽이 타원형으로 된 캠 링 안에서 로터가 회전하면 베인과 캠 링의 안쪽 벽 및 로터의 바깥쪽 벽으로 둘러싼 공간의 용적이 증감하여 펌프작용을 하게 되어 있다.Here, the hydraulic pump is composed of a pump body, a pump shaft, a rotor, vanes, cam rings and bearings, and the inner wall of the vane and cam ring and the outer wall of the rotor when the rotor rotates in the cam ring of the inner wall is oval The volume of the surrounding space increases and decreases to act as a pump.

그리고 상기 유압펌프를 구동하는 엔진은 운전 중의 회전수가 광범위하게 변동하기 때문에 동력조향장치의 작동유량을 항상 일정하게 유지하기 위해 오일의 양을 제어하는 유량조절밸브와, 동력조향장치의 유압회로내에 압력이 급격히 높아졌을 때에 회로의 안전을 위해 최고 유압을 제한하는 압력조절밸브가 설치되어 있다.In addition, since the engine speed driving the hydraulic pump varies widely during operation, a flow regulating valve for controlling the amount of oil to maintain a constant working flow rate of the power steering system, and a pressure in the hydraulic circuit of the power steering system. When the temperature rises sharply, a pressure regulating valve is installed to limit the maximum hydraulic pressure for safety of the circuit.

한편 상기와 같은 종래의 유압펌프에서 토출된 압유를 콘트롤밸브로 공급하는 고압호스는 펌프바디에 직접적으로 연결되게 되어 있는 데, 이 고압호스가 펌프바디에 연결된 구조는 도 1 에 도시된 바와 같다.On the other hand, the high pressure hose for supplying the pressure oil discharged from the conventional hydraulic pump as described above to the control valve is to be directly connected to the pump body, the structure is connected to the pump body as shown in FIG.

즉 펌프바디(101)의 토출구측에 고압호스(102)가 체결보울트(103)를 매개로 연결되고, 상기 체결보울트로 고압호스를 규정 토오크 이상으로 체결작업을 할 때에 고압호스가 회전되지 않도록 잡아주기 위해 클립(104)이 설치되어 있다.In other words, the high pressure hose 102 is connected to the discharge port side of the pump body 101 via the fastening bolt 103, and the high pressure hose is fastened so that the high pressure hose is not rotated when the high pressure hose is fastened to a specified torque or more with the fastening bolt. The clip 104 is provided for giving.

그런데 상기와 같은 종래의 동력조향장치의 유압펌프의 고압호스 연결구조에서는 고압호스의 연결시에 고압호스가 회전되지 않도록 하기 위해 별도의 클립을 사용해야 하므로, 부품수와 중량 및 비용을 증가시킨다고 하는 결점이 있었다.However, in the high pressure hose connection structure of the hydraulic pump of the conventional power steering device as described above, a separate clip must be used to prevent the high pressure hose from rotating during the connection of the high pressure hose, thereby increasing the number of parts, weight and cost. There was this.

이에 본 고안은 상기한 결점을 해소하기 위해 안출된 것으로, 고압호스의 연결작업시에 고압호스의 회전을 방지하기 위한 별도의 클립을 사용하지 않고 고압호스의 머리부와 흡입포트를 이용해서 고압호스의 회전을 방지해 줌으로써, 부품수와 중량 및 코스트의 저감을 도모할 수 있도록 된 동력조향장치의 유압펌프의 고압호스 회전방지장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above-mentioned shortcomings, and does not use a separate clip for preventing the rotation of the high pressure hose during the connection of the high pressure hose. It is an object of the present invention to provide a high pressure hose anti-rotation device for a hydraulic pump of a power steering device that can reduce the number of parts, weight and cost by preventing rotation of the engine.

도 1 은 종래 기술에 따른 동력조향장치의 유압펌프의 고압호스가 클립을 매개로 고정되게 장착된 상태의 개략적인 사시도이고,1 is a schematic perspective view of a state in which a high pressure hose of a hydraulic pump of a power steering apparatus according to the prior art is fixedly mounted through a clip;

The high pressure hose 2 is fastened to the pump body 1 of the hydraulic pump via the bolt 3.

여기서 상기 고압호스를 펌프바디에 체결작업을 할 때에 고압호스가 회전되지 않도록 잡아주기 위해 회전방지장치가 설치되어 있는 데, 즉 고압호스의 머리부(4)에는 흡입호스(5)의 머리부(6)에 걸려지는 걸림홈이 절개되어 형성된 구조로 되어 있다.The anti-rotation device is installed to hold the high pressure hose so as not to rotate when the high pressure hose is fastened to the pump body. That is, the head 4 of the high pressure hose is provided with the head of the suction hose 5. 6) It has a structure formed by cutting the catching groove to be caught.

이에 따라 고압호스를 펌프바디에 체결보울트로 체결할 때에 체결보울트를 규정 토오크 이상으로 조여주기 위해 회전력을 가해줄 경우에, 이 회전력으로 고압호스가 회전되지 않도록 상기 고압호스의 걸림홈에 흡입호스의 머리부가 걸려지게 하면, 이들의 상호작용으로 고압호스의 회전이 방지되므로, 고압호스의 연결작업이 용이하게 이루어질 수 있게 된다.Accordingly, when the high pressure hose is tightened to the pump body with the tightening bolt, when the tightening bolt is applied to tighten the torque above the specified torque, the suction hose of the suction hose is inserted into the engaging groove of the high pressure hose so that the high pressure hose is not rotated by the torque. If the head is caught, the rotation of the high pressure hose is prevented by their interaction, it is possible to easily connect the high pressure hose.

상기와 같은 구조는 종래와 같이 별도의 클립을 사용하지 않으므로, 부품수와 중량 및 코스트의 저감을 도모할 수 있게 되는 것이다.Since the structure as described above does not use a separate clip as in the prior art, the number of parts, weight, and cost can be reduced.
