Abstract

A transmission for a vehicle is provided to prevent functional deterioration of oil caused by inflow of steam and contaminants into an inside of an air breather. An air breather(300) is formed to absorb and discharge air according to a change of internal temperature. The air breather is connected from a top end of an inside of a transmission case(100) to an inside of a combination part(210) of a converter housing(200). The air breather is installed at a transmission and is protruded to the outside of the transmission case. The air breather is formed with a tube-shaped structure. The inside of the converter housing is coupled with an engine so that the combination part is sealed to shield contaminants from the outside.

210 : 체결부 300 : 에어브리더210: fastening portion 300: air breather

본 발명은 자동차용 변속기에 관한 것으로서, 특히 내부의 온도 변화에 따라 에어를 흡입 및 배출하는 에어브리더가 변속기 케이스 내부의 상단으로부터 컨버터 하우징의 체결부 내측까지 연결된 자동차용 변속기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission for automobiles, and more particularly, to an automobile transmission in which an air breather for inhaling and discharging air in accordance with a temperature change therein is connected from an upper end of a transmission case to an inside of a fastening portion of a converter housing.

일반적으로 자동차에서 사용하는 변속기는 변속방식에 따라 수동변속기와 자동변속기 및 무단자동변속기 등으로 구분할 수 있으며, 엔진의 토크를 변환시켜 바퀴로 전달하는 기능 이외에도, 정차시 엔진의 공회전을 가능하게 하며, 구동륜의 회전 방향을 변환시켜 후진을 가능하게 한다.In general, transmissions used in automobiles can be classified into manual transmissions, automatic transmissions, and continuously variable transmissions according to the transmission method.In addition to converting the torque of the engine and transmitting it to the wheels, the engine can be idle when stopped. Reverse direction is made possible by changing the direction of rotation of the drive wheels.

또한 자동변속기는 오일펌프에서 공급되는 압축유체에 의해 작동되는 클러치나 브레이크와 같은 각종 마찰요소에 의해서, 유성기어장치를 구성하고 있는 기어들이 선택적으로 치합됨으로써, 차량의 주행속도 및 스로틀밸브의 개도량에 따라 운전조건에 맞게 최적으로 변속이 수행되는 구조를 지닌다.In addition, the automatic transmission is selectively engaged with the gears constituting the planetary gear system by various friction elements such as a clutch or a brake operated by a pressurized fluid supplied from an oil pump, thereby driving the vehicle speed and opening amount of the throttle valve. According to the operating conditions, the shifting is optimally performed.

이러한 변속기는 차속이나 운전조건에 맞게 자동 또는 수동으로 유압을 변환하여 유성기어장치를 조작하는 유압제어기구에 의해서 수행된다.Such a transmission is performed by a hydraulic control mechanism for operating a planetary gear device by converting hydraulic pressure automatically or manually according to vehicle speed or driving conditions.

이때 상기 유압제어기구에는 오일탱크에 저장되어 있는 오일을 압송하는 오일펌프와, 상기 오일펌프에서 압송된 작동유체를 유성기어장치로 분배하는 유로를 형성하고 있는 밸브바디가 포함되어 있다.At this time, the hydraulic control mechanism includes an oil pump for pumping oil stored in the oil tank, and a valve body for forming a flow path for distributing the working fluid pumped from the oil pump to the planetary gear device.

또한 변속기 케이스에는 선기어, 유성기어, 링기어와 같은 유성기어장치를 비롯하여, 클러치나 브레이크와 같은 마찰요소를 윤활하게 작동시키기 위한 변속기 오일이 들어있다.The transmission case also contains planetary gears such as sun gears, planetary gears and ring gears, as well as transmission oils for lubricating friction elements such as clutches and brakes.

이때 마찰과정에서 발생된 마찰열 등에 의해 변속기 오일의 온도가 상승되면서 기체의 체적이 증대되므로 공기를 외부로 배출시켜야 하는데 이를 위해 에어브리더를 사용한다.At this time, as the temperature of the transmission oil is increased by frictional heat generated during the friction process, the volume of the gas is increased, so the air must be discharged to the outside.

도 1은 종래의 자동차용 변속기에 대한 일실시예를 도시하는 정면도이다.1 is a front view showing an embodiment of a conventional automobile transmission.

종래의 변속기는 도 1에 도시된 바와 같이, 내부의 압력을 대기압으로 유지시키고, 온도 변화에 따라 에어의 흡입 및 배출을 위해 변속기 케이스(100)의 내부 상단에서부터 컨버터 하우징(200) 외측 상단까지 연결된 에어브리더(300)를 포함한다.As shown in FIG. 1, the conventional transmission maintains the internal pressure at atmospheric pressure and is connected from the upper end of the transmission case 100 to the upper end of the converter housing 200 for intake and discharge of air according to a temperature change. It includes an air breather (300).

그러나, 종래에는 에어브리더가 변속기 오일이 누유되지 않게 하기 위해 변속기 케이스의 최상단에 위치하게 됨으로써, 수증기 및 오염물질이 내부로 들어와 변속기 오일의 기능을 저하시키는 문제점이 있었다.However, in the related art, since the air breather is positioned at the top of the transmission case in order to prevent leakage of the transmission oil, there is a problem in that water vapor and contaminants enter the interior and reduce the function of the transmission oil.

본 발명은 상기의 문제점을 해소하기 위한 것으로, 수증기 및 오염물질이 에어브리더 내부로 유입되어 변속기 내부의 오일 기능을 저하시키지 않도록 외부 오염물질을 차단하는 자동차용 변속기를 제공하고자 한다.The present invention is to solve the above problems, to provide an automobile transmission that blocks external contaminants so that water vapor and contaminants are introduced into the air breather to reduce the oil function inside the transmission.

이러한 본 발명은 내부의 온도 변화에 따라 에어를 흡입 및 배출하는 에어브리더를 포함하여, 그 내부의 압력을 대기압으로 유지시키는 자동차용 변속기에 있어서, 상기 에어브리더는 변속기 케이스 내부의 상단으로부터 컨버터 하우징의 체결부 내측까지 연결됨으로써 달성된다.The present invention includes an air breather for inhaling and discharging air according to a temperature change therein, and in an automobile transmission for maintaining the pressure therein at atmospheric pressure, the air breather is connected to the converter housing from an upper end of the transmission case. This is achieved by connecting up to the inside of the fastening part.
