Publication number: 20110246037Abstract: A hydraulic pressure control apparatus for a lockup clutch of a fluid transmission device. In a spool of the lockup relay valve, switching to a position on an engaging side (right half position) for engaging a lockup clutch is achieved by a signal pressure being input from a linear solenoid valve to a hydraulic oil chamber, and switching to a position on a releasing side (left half position) for releasing the lockup clutch is achieved by an urging member such as a spring force of a spring. Since the response is low with the switching by the spring force, the state of a vehicle is sensed by a sensor and, if quick release of the lockup clutch is necessary, a signal pressure from a solenoid valve is input to a hydraulic oil chamber to apply the spring force, and assists with a hydraulic pressure, thereby switching the spool to the releasing side. Accordingly, the response when the lockup relay valve is switched from the engaging side to the releasing side is enhanced.Type: ApplicationFiled: February 24, 2011Publication date: October 6, 2011Applicant: AISIN AW CO., LTD.Inventors: Tetsuya SHIMIZU, Kenichi Tsuchida, Kazunori Ishikawa

Publication number: 20110219904Abstract: A hydraulic control apparatus of an automatic transmission including a switching portion which, at the same time as a reverse range pressure oil passage and a discharge delay oil passage which delays an oil pressure output are connected, causes the reverse range pressure oil passage and discharge delay oil passage, by switching between the two, in order to communicate with a hydraulic servo. The switching portion causes the hydraulic servo and discharge delay oil passage to communicate when a manual valve is switched to an N range, and causes the hydraulic servo and reverse range pressure oil passage to communicate when the manual valve (MV) is switched to a D range or an R range. Because of this arrangement, it is difficult for oil, when discharged from the hydraulic servo, to drain at an R-N switching time, and it is easy for oil to drain in the D range or the like.Type: ApplicationFiled: February 9, 2011Publication date: September 15, 2011Applicant: AISIN AW CO., LTD.Inventors: Tetsuya Shimizu, Yoshimitsu Hyodo, Satoshi Nishio, Kazuki Kojima, Kazunori Ishikawa
