본 발명은 조향장치의 리저버탱크에 관한 것으로서, 특히 탱크본체 내로 오일이 과도한 압력으로 유입될 경우 오일의 와류 현상을 자연스럽게 저하시킬 수 있도록 하는 조향장치의 리저버탱크에 관한 것이다.The present invention relates to a reservoir tank of a steering device, and more particularly, to a reservoir tank of a steering device to naturally reduce the vortex of oil when oil is introduced into the tank body at an excessive pressure.

일반적으로 자동차의 조향장치는 자동차의 진행 방향을 운전자의 의지대로 변경할 수 있도록 하기 위한 장치로서 자동차의 앞바퀴가 선회하는 회전 중심을 임의로 변경하여 운전자가 원하는 방향으로 자동차를 진행시킬 수 있도록 보조하는 장치이다.In general, the steering device of a vehicle is a device for changing the driving direction of the vehicle at the driver's will, and is a device that assists the driver in advancing the vehicle in a desired direction by arbitrarily changing the rotation center of the front wheel of the vehicle. .

조향장치로는 유압식 동력 보조 조향장치(HPS: Hydraulic Power Steering Apparatus)가 대표적인데, 이는 운전자가 자동차의 조향휠(Steering Wheel)을 조작할 경우 배력 장치를 이용하여 운전자의 조향 휠 조작력을 보조하여 줌으로써 보다 작은 힘으로 용이하게 차량의 진행 방향을 변경할 수 있도록 하는 장치이다.Hydraulic power steering steering (HPS) is a representative steering device. When a driver operates a steering wheel of a car, the steering device assists the driver's steering wheel operation by using a power booster. It is a device that can easily change the direction of travel of the vehicle with a smaller force.

이와 같은 조향장치는 오일이 랙 바(Rack Bar)와 연결되어 있는 실린더에 오일을 안정적으로 공급함과 동시에 저장하도록 하는 리저버탱크를 포함한다.Such a steering device includes a reservoir tank that allows oil to stably supply and store oil in a cylinder connected to a rack bar.

도 1에 도시된 바와 같이, 종래 기술에 따른 조향장치의 리저버탱크(10)는 탱크본체(1), 캡(2), 상기 탱크본체(1) 내에 설치되는 격판(3)으로 구성된다.As shown in Figure 1, the reservoir tank 10 of the steering apparatus according to the prior art is composed of a tank body (1), a cap (2), a diaphragm (3) installed in the tank body (1).
