Summary: | To provide a hydraulic control device for vehicular transmission device which enables supply of a lubrication pressure and supply of a working pressure of a parking device by one electric oil pump, and which can achieve cost reduction.SOLUTION: A hydraulic control device 1includes: oil passages L1, L8, L9 and oil passages L1, L2, L3 communicating with a strainer 10; and an electric oil pump 11 having an input/output port 11b communicating with the oil passages L1, L8, L9, and an input/output port 11a communicating with the oil passages L1, L2, L3. Then, the electric oil pump 11 supplies a lubrication pressure to the oil passages L3, L4, L5, L6, L7 by being driven in a normal rotation direction and by absorbing an oil from the input/output port 11b and discharging it from the input/output port 11a, and supplies a working pressure with respect to a parking device 20 to the oil passages L9, L10, L12 by being driven in a reverse rotation direction and by absorbing an oil from the input/output port 11a and discharging it from the input/output port 11b.SELECTED DRAWING: Figure 3
【課題】1つの電動オイルポンプによって潤滑圧の供給とパーキング装置の作動圧の供給とを可能にし、コストダウンを図ることが可能な車両用伝動装置の油圧制御装置を提供する。【解決手段】油圧制御装置11は、ストレーナ10に連通する油路L1,L8,L9及び油路L1,L2,L3と、その油路L1,L8,L9に連通する入出力ポート11bと、その油路L1,L2,L3に連通する入出力ポート11aとを有する電動オイルポンプ11とを備えている。そして、電動オイルポンプ11は、正転回転方向に駆動されて入出力ポート11bから油を吸入して入出力ポート11aから排出することで油路L3,L4,L5,L6,L7に潤滑圧を供給し、逆転回転方向に駆動されて入出力ポート11aから油を吸入して入出力ポート11bから排出することで油路L9,L10,L12にパーキング装置20に対する作動圧を供給する。【選択図】図3 |
