Description

자동변속기오일의 자동보충장치Automatic refill of automatic transmission oil

본 발명은 자동변속기오일의 자동보충장치에 관한 것으로, 특히 자동변속기내 오일의 양이 부족할 때 이를 감지하여 자동으로 부족한 만큼의 오일을 보충될 수 있게 함으로써, 자동변속기내에는 오일이 항상 적절한 양으로 유지되어 자동변속기의 성능저하를 예방할 수 있도록 된 자동변속기오일의 자동보충장치에 관한 것이 다.The present invention relates to an automatic refilling device for automatic transmission oil, and in particular, by detecting when the amount of oil in the automatic transmission is insufficient to automatically replenish as much oil as necessary, the oil is always in an appropriate amount in the automatic transmission. The present invention relates to an automatic refilling device for automatic transmission oil, which is maintained to prevent performance degradation of the automatic transmission.

일반적으로 자동차에 탑재된 자동변속기는 주행중 기어의 변속조작이 불필요하기 때문에 운전하기가 편리하고 운전피로가 경감될 뿐만 아니라 엔진의 회전력이 유체를 매개로 전달되므로 자동차의 발진이나 가속 및 감속이 원활하여 승차감이 좋고, 또 과부하가 걸려도 엔진에 직접적으로 가해지지 않으므로 엔진을 보호하고 각 부품의 수명을 연장시키는 장점을 갖고 있다.In general, the automatic transmission mounted on the vehicle is convenient to operate because the gear shifting operation is not necessary while driving, it is convenient to reduce the driving fatigue, and the rotational force of the engine is transmitted through the fluid, so the starting, acceleration and deceleration of the vehicle is smooth. It has a good ride comfort and is not directly applied to the engine even when overloaded, which protects the engine and extends the life of each part.

이와 같은 자동변속기는 엔진의 회전력을 액체의 운동에너지로 바꾸고 이 에너지를 다시 동력을 바꾸어 변속기에 전달하는 유체클러치와, 유체의 운동 에너지를 자동적으로 전달토오크로 변환하는 토오크 변환기, 이 토오크 변환기의 토오크 변환능력을 보조하고 또한 후진 조작을 위해 토오크 변환기의 뒷부분에 결합되면서 유성기어를 비롯하여 다판클러치와 브레이크 밴드 및 1방향 클러치 등으로 구성된 유성 기어변속 장치, 자동차의 주행속도와 엔진의 부하 및 변속레바의 위치에 따라 자동적으로 유성 기어 유닛의 브레이크밴드와 클러치를 작용시키거나 해방시켜 자동차가 원활한 주행이 되도록 변속조작하는 유압 제어장치 등을 갖춘 구조로 되어 있다.Such automatic transmission converts the rotational force of the engine into the kinetic energy of the liquid and converts the energy back to the transmission to transmit the energy to the transmission, and a torque converter that automatically converts the kinetic energy of the fluid into a transmission torque, which is the torque of the torque converter. The planetary gear transmission consists of a planetary gear, a multi-plate clutch, a brake band, and a one-way clutch, which is coupled to the rear of the torque converter for assisting the converting ability and for reverse operation. According to the position, the brake band and the clutch of the planetary gear unit are automatically actuated or released to have a hydraulic control device for shifting the vehicle for smooth driving.

한편, 종래 자동변속기내 오일의 잔존량을 확인하기 위해서는 차량을 몇분정도 기동시켜 엔진과 자동변속기 오일이 규정온도까지 상승시킨 다음, 엔진의 공회전상태에서 기어를 중립위치에 놓고서 엔진룸내의 오일레벨게이지를 빼내 육안으로 확인해야만 하였다.On the other hand, in order to check the amount of oil remaining in the conventional automatic transmission, start the vehicle for several minutes, raise the engine and automatic transmission oil to the specified temperature, and put the gear in a neutral position in the engine idle state, and place the oil level gauge in the engine room. Had to be removed and visually checked.

따라서 운전자가 자동변속기의 오일의 양을 확인하기가 용이하지 않음으로 인해 오일의 양을 확인하는 정비는 통상 실시되지 않는 것이 일반적이다.Therefore, it is not common for the operator to check the amount of oil because it is not easy for the driver to check the amount of oil in the automatic transmission.

그런데, 자동변속기의 오일이 부족해지면 자동변속기의 성능이 저하됨은 물론, 변속기의 수명도 단축되면서 자동차의 정상주행에도 곤란한 단점이 있었다.However, when the oil of the automatic transmission is insufficient, the performance of the automatic transmission is reduced, as well as the life of the transmission is shortened, and there is a disadvantage in that the normal driving of the vehicle is difficult.

이에 본 발명은 상기와 같은 단점을 해소하기 위해 안출된 것으로, 자동변속기내 저장된 오일의 양이 부족해지면 이를 자동으로 감지하여 부족분 만큼의 오일이 자동으로 공급될 수 있도록 하여 자동변속기의 성능저하를 예방할 수 있도록 된 자동변속기오일의 자동보충장치를 제공함에 그 목적이 있다.Therefore, the present invention is devised to solve the above disadvantages, and when the amount of oil stored in the automatic transmission is insufficient, it automatically detects it so that the oil can be supplied as much as the shortage to prevent performance degradation of the automatic transmission. It is an object of the present invention to provide an automatic refilling device for automatic transmission oil.

제1도는 본 발명에 따른 자동변속기오일의 자동보충장치를 도시한 구성도이다.1 is a block diagram showing an automatic refilling device for automatic transmission oil according to the present invention.
