摘要： PROBLEM TO BE SOLVED: To suppress rise of oil temperature likely to occur in high speed driving in a hydraulic control device of an automatic transmission in which a part of delivery oil from a hydraulic pump 11 is supplied to a main hydraulic circuit part 10 for controlling various hydraulic actuators of the automatic transmission, and in which another part of delivery oil from the hydraulic pump is supplied to a lubrication system 22 and an oil cooler 23 in the automatic transmission. SOLUTION: Leak oil from a regulator 24 to regulate supply oil pressure (lubricating pressure) to the lubrication system 22 is supplied to the oil cooler 23. A solenoid valve 25 is connected to an oil chamber 24a for controlling pressure regulation of the regulator 24 to control lubricating pressure so as to be increased or decreased by the solenoid valve 25. In high speed driving, the lubricating pressure is reduced under the condition of low load operation of an engine, and supply oil quantity to the oil cooler23 is increased.

摘要： PROBLEM TO BE SOLVED: To reduce the rotational loss of a pulley, in a vehicular transmission having a transmission consisting of a drive pulley, driven pulley and drive belt. SOLUTION: The inlet opening 41 of a discharge oil passage 76 is provided on the tangential line direction part combining the outer peripheries of circles made by the maximum diameter of the drive belt and the minimum diameter of the driven pulley in the transmission storing chamber R1 for storing the transmission consisting of a drive pulley 8, a driven pulley 9 and a drive belt 10. The inlet opening 41 of the discharge oil passage 76 is provided on the tangential direction part for combining the outer periphery upper sides of the drive pulley 8 and driven pulley 9 of the transmission storing chamber R1. By providing the inlet opening of the discharge oil passage as such, the lubrication oil scattered from the drive belt 10 is discharged from the discharge opening 41 to the outside of the storing chamber of the transmission directly and effectively. The discharged lubricant is sent to an oil pan 26 through the discharge oil passage 76 provided on the housing. Therefore, the lubricant amount flowing the inner wall of the transmission storing chamber is reduced and the oil amount of a lower oil pan can be ensured and the rotational loss by the stiring of the lubricant can be reduced.

摘要： PROBLEM TO BE SOLVED: To redress the imbalance in the return rate of lubricating oil into an oil pan between the devices of a vehicular transmission having a case that contains a continuously variable transmission and a driving force transmission device having a driveaway device. SOLUTION: A vehicular transmission housing 2 includes a first chamber containing a continuously variable transmission, and a second chamber containing a driving force transmission device including a driveaway device, a reduction gear, a differential gear and a power transmission device for an oil pump. The first and second chambers each have inlets 72 to 74 to an oil discharge passage for returning lubricating oil to the upper portion of an oil pan on the associated horizontal side perpendicular to the input or output shaft of the continuously variable transmission. The chambers also each have wall surfaces 61 to 65 for leading lubricating oil to the discharge port, so that lubricating oil from all those devices are distributed to the sides of the oil pan. This constitution stabilizes the lubricating-oil discharge rate returned from both chambers to the oil pan to thus equalize the lubricating oils in the oil pan.

摘要：【課題】無段自動変速機において、仮想的な固定変速段を設定することなく、手動変速モードで充分な加減速度が得られるようにする。【解決手段】手動変速時に目標レシオ算出手段M7により算出される手動変速時目標レシオImの現レシオIに対する偏差は、自動変速時に目標レシオ算出手段M4により算出される自動変速時目標レシオIaの現レシオIに対する偏差よりも大きく、かつ1段の手動変速操作による手動変速時目標レシオImの変化量は手動変速操作毎に減少するので、複数回の手動変速操作を連続して行う場合に、最初の操作で最も強い加減速度が発生し、その後の操作で発生する加減速度が順次減少することで、運転者の意図する加減速度を容易に発生させてスポーツ走行時のドライバビリティを高めることができる。しかも、手動変速時目標レシオImを算出するのに仮想的な固定変速段のマップを必要としないので、そのマップを開発するための時間やコストを削減することができる。【選択図】図2

摘要： PROBLEM TO BE SOLVED: To reduce rotational loss of a pulley in a transmission for a vehicle comprising a driving pulley, a driven pulley and a driving belt. SOLUTION: A cover member 51 is provided to cover the outer periphery of a lower part including pulley rotating speed detecting protrusion parts 52 of a driving pulley 8 positioned below in a transmission device storage chamber R1 for storing a transmission device comprising the driving pulley 8, a driven pulley 9 and a driving belt 10. The tip face 51bs of a face, opposed to the pulley chamber internal wall surface 54, of the cover member 51 is disposed with a clearance V to the pulley chamber internal wall surface 54. With a transmission for a vehicle thus constituted, the infiltration quantity of lubricating oil into the vicinity of the outer periphery of the pulley positioned below is reduced to restrain lubricating oil from being agitated by the protrusion parts of the rotating pulley, thereby reducing rotational loss of the pulley and preventing oxidation and degradation of lubricating oil.
