본 발명은 변속기의 오일 쿨링장치에 관한 것으로, 보다 상세하게는 내장형 오일 쿨러를 설치함으로써, 변속기 오일의 쿨링 효과를 높일 수 있는 변속기의 오일 쿨링장치에 관한 것이다.The present invention relates to an oil cooling device for a transmission, and more particularly, to an oil cooling device for a transmission that can increase the cooling effect of transmission oil by installing a built-in oil cooler.

일반적으로 차량의 변속 장치는 엔진의 구동력을 구동륜에 전달하는 기능을 갖고 있으며, 이러한 변속 장치에는 운전자의 의지대로 변속단을 직접 선택하는 수동변속기(Manual Transmission)와, 차량의 주행조건에 따라 자동적으로 변속이 이루어지는 자동변속기(Automatic Transmission)와, 각 변속단 사이에 특정한 변속영역 없이 무단으로 변속이 이루어지는 무단변속기(Continuously Variable Transmission, CVT)로 분류된다.In general, the transmission of the vehicle has a function of transmitting the driving force of the engine to the driving wheel, and such a transmission includes a manual transmission for manually selecting a transmission stage at the driver's will, and automatically according to the driving conditions of the vehicle. It is categorized into an automatic transmission in which a shift is made and a continuously variable transmission (CVT) in which a continuously variable shift is performed without a specific shift region between each shift stage.

무단변속기는 유압을 이용하는 자동변속기의 단점을 보완하여 연비 및 동력성능 그리고 중량면에서 큰 장점을 가지고 있으며, 벨트로 연결되는 풀리를 입력축과 출력축에 각각 장착하고, 풀리의 외경을 상대적으로 변환시키는 방식이 주로 사용된다.The continuously variable transmission has a great advantage in terms of fuel efficiency, power performance, and weight by compensating for the shortcomings of an automatic transmission that uses hydraulic pressure, and the pulley connected to the belt is mounted on the input shaft and the output shaft, respectively, and the outer diameter of the pulley is relatively converted. It is mainly used.

종래 기술에서 무단변속기는 자동변속기에 비해 고압을 형성하므로, 작동시 온도 상승이 비교적 빠르며, 자동변속기와 동일한 오일 쿨러를 사용할 경우, 쿨링 효과가 떨어지는 문제가 있다. 따라서 이를 개선할 필요성이 요청된다. In the prior art, the continuously variable transmission forms a high pressure compared to the automatic transmission, so the temperature rise during operation is relatively fast, and when using the same oil cooler as the automatic transmission, there is a problem that the cooling effect is poor. Therefore, there is a need to improve this.
