Description
본 발명은 브레이크 오일 부족시 자동 변속차량의 파킹 레인지 홀딩장치에 관한 것으로서, 상세하게 자동 변속차량에서 브레이크 오일 부족이 센서에 의해 감지되면 액추에이터가 자동 변속기의 P 레인지를 홀딩하여 출발이 불가능하게 함으로써 예상될 수 있는 추돌 위험으로부터 사고를 미연에 예방할 수 있게 한 브레이크 오일 부족시 자동 변속차량의 파킹 레인지 홀딩 장치에 관한 것이다.The present invention relates to a parking range holding device for an automatic transmission vehicle when brake oil is low, and more particularly, to a parking range holding device for an automatic transmission in which, when a brake oil shortage is detected by a sensor in an automatic transmission, an actuator holds a P range of an automatic transmission, The present invention relates to a parking range holding device for an automatic transmission vehicle that is capable of preventing an accident from occurring due to a collision danger that may occur when a brake oil is low.
일반적으로 브레이크 오일은 차량의 브레이크 계통의 라인 및 장치에 작용되는 오일 형태의 액체로서 브레이크 폐달의 물리적인 힘을 전달받아 브레이크 마스터 실린더와 부스터를 통해 유압으로 변경/증폭되어 브레이크 라인을 따라 브레이크 라이닝에 제동력을 제공하는 제동에 필수적인 액체이며 대개 파스칼 원리에 의해 폐달의 물리적인 힘이 유압으로 배가되는 특징을 가지고 있으며, 비점이 높고 빙점이 낮은 액체를 사용하고 온도에 대한 점도의 변화가 적고 화학적으로 안정되어 있는 것이 필요하며, 예전에는 파마자유를 사용하였으나 현재에는 합성유로 바뀌어 에틸렌 글리콜이나 에텔 등을 주로 사용하고 있으며, 흡수성이 있어 특히 수분에 의해 비점이 내려가므로 취급에 주의가 필요한 오일이며, 일명 브레이크 플루이드라 하기도 한다.In general, brake oil is an oil-like liquid that acts on the brake system line and device of a vehicle. It receives the physical force of the brake pendulum and is changed / amplified to the hydraulic pressure through the brake master cylinder and the booster. It is an essential liquid for braking which provides braking force. It is characterized by the fact that the physical force of puddle is multiplied by hydraulic pressure by Pascal principle. It uses liquid with low boiling point and low freezing point, In the past, it was used as a free oil, but now it is converted to synthetic oil, and ethylene glycol or ether is mainly used. Since it has an absorbent property, its boiling point is lowered by moisture, It is also called a fluid.
상기한 브레이크 오일은 브레이크 오일의 리저버 탱크에 항시 일정량 이상 충만되어 있어야 브레이크 장치에 정상적인 유압을 발생하여 제동력을 제공할 수 있게 되나, 브레이크 계통 장치에 이상이 발생하여 누유현상에 의한 오일 부족사태가 발생되면 주행중 제동력을 상실케 하는 근본적인 원인을 제공하여 차량을 추돌 사태로부터 회피할 수 없게 하는 주 요인이 된다.If the brake oil is filled in the reservoir tank of the brake oil more than a predetermined amount at all times, a normal hydraulic pressure is generated in the brake unit to provide the braking force. However, an abnormality occurs in the brake system unit, It is a major factor that prevents the vehicle from avoiding the collision by providing the fundamental cause of losing the braking force during driving.
그러나, 종래에는 상기한 브레이크 오일의 부족현상이 발생되어도 별도의 경고없이 차량이 주행할 수 있게 되어 있으며, 특히 자동 변속차량에서는 브레이크 오일 부족시 주행하게 되면 수동 변속차량보다도 위험이 훨씬 증대되는 문제점이 있었다.However, in the related art, even if a shortage of the brake oil occurs, the vehicle can be driven without warning. Particularly, in an automatic transmission, when the vehicle runs short of brake oil, there was.
이에, 본 발명은 상기와 같은 문제점을 해소하기 위하여, 발명한 것으로서, 브레이크 리저버 탱크의 오일량을 감지하는 브레이크 오일센서에 의해 자동 변속차량의 파킹레인지를 액추에이터로 홀딩하여 차량의 주행을 경고 및 제한하게 하는 장치를 제공하는 데 그 목적이 있다.The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a brake oil sensor for detecting an oil amount of a brake reservoir tank, The present invention has been made in view of the above problems.
따라서, 본 발명은 자동 변속차량의 브레이크 오일 리저버 탱크(40)에 설치되어 오일의 량을 감지하는 브레이크 오일센서(30)가 오일 스위치(50)에 의해 액셀폐달 스위치(20)의 작동을 전달하는 파킹레인지의 액추에이터(10)를 차단하여 파킹레인지가 홀딩되게 하는 것을 그 특징으로 한다.Therefore, the present invention is characterized in that the brake oil sensor 30 installed in the brake oil reservoir tank 40 of the automatic transmission vehicle for sensing the amount of oil transfers the operation of the accelerator pedal depression switch 20 by the oil switch 50 And the actuator 10 of the parking range is blocked to hold the parking range.
