Description

자동변속기의 냉각오일 막힘경고장치Cooling oil clogging warning device of automatic transmission

본 발명은 자동변속기의 냉각오일 막힘경고장치에 관한 것으로서, 더 자세하게는 변속기에서 유압이 빠져 나오는 압력을 측정하여 냉각오일의 막힘여부로 전기적인 신호에 의해 유압이상을 미연에 방지하여 자동변속기의 내구성을 향상하고자 하는자동변속기의 냉각오일 막힘경고장치에 관한 것이다.The present invention relates to a cooling oil clogging warning device of an automatic transmission, and more particularly, by measuring the pressure exiting the hydraulic pressure from the transmission to prevent the abnormality of the hydraulic oil by electrical signals due to clogging of the cooling oil to prevent durability of the automatic transmission. The present invention relates to a cooling oil clogging warning device for an automatic transmission.

일반적으로 변속기는 자동차의 주행상태 변화에 따른 엔진의 회전력을 증대시키거나 감소시켜 전진 역진하는 것이다.In general, the transmission is to move forward by increasing or decreasing the rotational force of the engine in accordance with the change of the driving state of the vehicle.

이러한 변속기는 주행상태를 자동으로 변속하기 위해 자동변속기를 갖추고 있다.This transmission is equipped with an automatic transmission for automatically shifting driving conditions.

자동변속기는 클러치작용과 트랜스미션의 자동으로 동작시키게 된다.The automatic transmission automatically operates the clutch and the transmission.

통상적인 종래의 자동변속기에 관해 설명하면 다음과 같다.A conventional conventional automatic transmission will be described as follows.

도 1은 종래의 자동변속기의 블록구성도이고, 도 2는 종래의 자동변속기의 부분 확대단면도이다.1 is a block diagram of a conventional automatic transmission, and FIG. 2 is a partially enlarged cross-sectional view of a conventional automatic transmission.

이러한 종래의 자동변속기는 도 1 또는 도 2에서 보는 바와 같이 차량의 진행방향을 변속제어하여 동력을 전달하는 변속기(2)와 상기 변속기(2)의 외측면에 내부의 압력을 일부 배출하기 위해 유도하는 관(4)과, 상기 관(4)의 상단을 덮어 내압 전체가 외부로 빠져나가지 않도록 하는 캡(3)을 갖는 브리더(1)를 연결구성하고 있다.As shown in FIG. 1 or FIG. 2, the conventional automatic transmission induces the transmission 2 to transmit power by shift control of the traveling direction of the vehicle and to discharge some of the internal pressure on the outer surface of the transmission 2. And a breather 1 having a cap 3 that covers the upper end of the tube 4 and prevents the entire internal pressure from escaping to the outside.

이러한 종래의 자동변속기는 차량을 운행하면서 동력발생하고 이동력을 이용하여 차량을 운행하기 위해 전달장치에 보내게 되면 특히 브리더(1)는 변속기(2)내부의 유압제어장치에서 발생하는 과열 및 내압을 외부로 일부 배출하여 내부의 공기가 외부로 빠져나갈 수 있도록 하는 것이다.When the conventional automatic transmission generates power while driving a vehicle and is sent to a transmission device for driving the vehicle by using the moving force, the breather 1 is particularly overheated and internal pressure generated by the hydraulic control device inside the transmission 2. Part of the discharge to the outside to allow the air inside to escape to the outside.

그러나, 종래의 기술은 변속기내에 공급하는 오일이 규정치보다 적을 경우 밸브 몸체가 오일을 충분히 흡수하지 못하여 클러치를 작동시키는 피스톤에 규정압력을 전달하지 못하여 자동변속기의 손상을 가져오게 되며 오일이 규정치보다 클경우 변속기 내부의 회전체들이 오일과 부딪혀 기포를 발생시키고 이 기포가 밸브바디 의 유압회로에 들어가 압력이 규정대로 전달되지 못한다.However, the conventional technology is that when the oil supplied to the transmission is less than the specified value, the valve body does not absorb the oil sufficiently and fails to transmit the prescribed pressure to the piston actuating the clutch, resulting in damage to the automatic transmission. In this case, the rotors inside the transmission collide with the oil to create bubbles, which enter the hydraulic circuit of the valve body and the pressure cannot be delivered as specified.

이렇게 되면 클러치의 슬립이 발생하게 되고 클러치 클립이 발생되면 오일 온도가 상승, 오일볼룸(volume)상승, 회전체와 부딪히게 되어 기포가 발생하게 되어 결국에는 자동변속기 내부의 내압이 커지게 되어 변속기오일이 자동변속기 케이스에 꽃혀있는 브리더(breather)를 통해 밖으로 분출하게 되면서 많은 량의 오일이 분출하게 되므로서 화재 위험에 대한 문제점을 가지게 된다.In this case, the clutch slips, and when the clutch clip is generated, the oil temperature rises, the oil ballroom rises, the rotor collides with the air bubbles, and the internal pressure inside the automatic transmission increases. As the jet is blown out through the breather flowered in the automatic transmission case, a large amount of oil is ejected, which causes a fire hazard.

본 발명은 이와 같은 종래의 제반 문제점을 해결하기 위기 위해 안출한 것으로서 그 목적은 변속기에서 유압이 빠져 나오는 압력을 측정하여 냉각오일의 막힘여부로 전기적인 신호에 의해 유압이상을 미연에 방지하여 자동변속기의 내구성을 향상하고자 하는 데 있다.The present invention has been made in order to solve the above-mentioned conventional problems, the purpose of which is to measure the pressure of the hydraulic pressure from the transmission to prevent clogging of the cooling oil by the electrical signal to prevent the hydraulic abnormality in advance by automatic transmission The purpose is to improve the durability of the.
