Abstract

본 발명은 자동 변속기용 오일 펌프의 구동 방법에 관한 것이다.The present invention relates to a method of driving an oil pump for an automatic transmission.

일단(10a)이 오일 펌프의 이너 로터(13)에 습동가능하게 맞물려 있고 타단(10b)이 토크 컨버터의 프론트 커버(11)측에 측선 방향으로 습동가능하게 선택적으로 맞물리는 오일 펌프 샤프트(10)를, 드라이브 레인지시에는 상기 일단(10a)에 축선방향으로 가해지는 유압에 의해 상기 프론트 커버(11)측에 맞물리게 하여 오일 펌프를 구동시키고, 중립 레이지시에는 상기 타단(10b)에 축선방향으로 가해지는 유압에 의해 상기 프론트 커버(11)측으로부터 이탈되게 하여 오일 펌프로의 엔진 구동력을 차단한다.An oil pump shaft 10 in which one end 10a is slidably engaged with the inner rotor 13 of the oil pump and the other end 10b is slidably engaged selectively in the lateral direction on the side of the front cover 11 of the torque converter, The oil pump is driven by engaging with the front cover 11 side by the oil pressure applied in the axial direction to the one end 10a in the drive range and in the axial direction to the other end 10b in the neutral rage The oil pressure is released from the front cover 11 side to shut off the engine driving force to the oil pump.

이에 따라, 중립 레인지에서 오일 펌프가 구동하지 않으므로 연비가 향상된다.Accordingly, since the oil pump is not driven in the neutral range, the fuel consumption is improved.

Claims

An oil pump shaft 10 in which one end 10a is slidably engaged with the inner rotor 13 of the oil pump and the other end 10b is slidably engaged selectively in the axial direction on the side of the prototype cover 11 of the torque converter, Is engaged with the side of the prot cover (11) by the oil pressure applied in the axial direction to the one end (10a) to drive the oil pump when in the drive range, and in the axial direction to the other end (10b) Wherein the front cover (11) is detached from the side of the front cover (11) by an oil pressure to shut off the engine driving force to the oil pump.
