Zusammenfassung:The present invention relates to a hydraulic transmission oil cooling device including: a cooling body coupled to a mission case; a receiving groove formed in the cooling body for accommodating oil; a cover part coupled to the cooling body to cover the receiving groove; a supply port for supplying oil to the receiving groove; a discharge port for discharging oil from the receiving groove; a separation unit coupled to the cooling body to separate a flow path formed in the accommodation groove into a supply flow passage connected to the supply port and a discharge flow passage connected to the discharge port, respectively; and a hurdle part coupled to each of the outer wall and the separating part of the cooling body. The hurdle part protrudes from the bottom surface of the cooling body to reduce the area of a flow region through which oil passes. 본 발명은 미션케이스에 결합된 냉각본체; 오일을 수용하기 위해 상기 냉각본체에 형성된 수용홈; 상기 수용홈을 덮도록 상기 냉각본체에 결합된 커버부; 상기 수용홈으로 오일을 공급하는 공급포트; 상기 수용홈으로부터 오일을 배출하는 배출포트; 상기 냉각본체에 결합되어 상기 수용홈에 형성된 유로를 상기 공급포트에 연결된 공급유로 및 상기 배출포트에 연결된 배출유로 각각으로 분리시키는 분리부; 및 상기 냉각본체의 외벽 및 상기 분리부 각각에 결합된 허들부를 포함하고, 상기 허들부는 오일이 통과하는 유동영역의 면적을 감소시키도록 상기 냉각본체의 바닥면으로부터 돌출되어 형성된 유압 트랜스미션 오일 냉각장치에 관한 것이다.
