摘要： PROBLEM TO BE SOLVED: To implement lubrication in which heat generation due to slip control of a frictional engagement element can be accommodated. SOLUTION: A lubricating device for a frictional engagement element B1 for locking a rotating member R to a case 9 comprises a hub 2 connected to the rotating member, a friction member 3 interposed between the hub and the case, a hydraulic servo 4 which engages the friction member, and an oil passage L for supplying a lubricating oil from the case to the friction member. A supply port Le of the oil passage is disposed on the inside in the diametrical direction and on one side in the axial direction with respect to the friction member and toward the friction member, and a weir member 5 which controls the escape of the lubricating oil in an axial direction from the clearance between the hub and the friction member is provided on the other side in the axial direction of the friction member. Thereby, the escape in the axial direction of the oil supplied to the internal circumferential side of the friction member is prevented by non-contact leakage control not causing a dragging resistance, the oil flow passing through the friction member outwardly in the diametrical direction is secured, and the friction member is cooled positively.

摘要： PROBLEM TO BE SOLVED: To provide a down-shift controlling device for automatic transmission for vehicle with which the generation of a shock caused by the finish of a throttle opening restraining control is preferably suppressed. SOLUTION: When a clutch-to-clutch down-shift judgment has been performed by a down-shift judgment deciding means 106, the drop of an engaging pressure of a relief side hydraulic friction engaging device is suppressed by a relief side hydraulic pressure drop suppressing and controlling means 110 until the finish of the throttle opening limiting control is decided by a throttle opening limiting control finish judgment means 104. Consequently, an engaging torque is not insufficient even when a turbine torque T T has returned at the finishing time of the throttle opening limiting control, and the engaging torque in clutch-to-clutch down-shifting is smoothly continued in the state that the turbine torque T T (=T IN ) is stable. As a result, the generation of a shock caused by the finish of the throttle opening restraining control is preferably suppressed. COPYRIGHT: (C)2004,JPO

摘要： PURPOSE:To enhance the rigidity of a first clutch member without increasing the axial length by fastening a first and a second outer members, forming the first clutch member, at two or more point different in radial dimension to form a box shape. CONSTITUTION:Oil pressure difference is generated to a space formed by a first clutch member 100 and a second clutch member 200 and around this space, and the first clutch member 100 and the second clutch member 200 are engaged and put in the locked-up state. A first and a second turbine drive plates 7, 8 which are a first and a second outer shell members forming the first clutch member 100 in the locked-up state are fastened by rivets 9 at parts different in radial dimension and welded. Box-shape cross section is thereby formed at the outer peripheral side part from the rivets 9, and box-shape cross section is formed at the inner peripheral side part, thus forming box shape. The first clutch member can be thereby thinned, and the axial length of the whole device can be shortened.

摘要： PROBLEM TO BE SOLVED: To surely execute learning compensation of control parameters for clutch engagement by comparing them with proper engaging timing set in advance and compensating engaging and control parameters per change gear pattern. SOLUTION: In case of continuous down shift of a change gear pattern, a change amount d/dt (NT) per unit time of the number of input rotation NT is computed (S803), the number of rotation NT is compared with the number of middle speed step synchronization NM (S804), and the change amount d/dt (NT) is compared with predetermined values AW1 and AW2 (S805, S806). At the time of NT AW1, compensation value update flag XCORW is set as 2 to delay the engagement (S810). Moreover, at the time of NT>NM and d/dt (NT) Ti>TOPTW1, the compensation value update flag XCORW is set as 1 to quicken the engagement (S811) to execute the updating of a compensation value and complete learning compensation.

摘要： PROBLEM TO BE SOLVED: To necessarily and sufficiently support lubricating oil for a friction- engaging device selectively slip-controlled and to prevent power loss due to unnecessary circulation of the lubricating oil. SOLUTION: This hydraulic control device of an automatic transmission can have a transmission state set by transferring a predetermined friction- engaging device B1 into a sliding state and the other transmission state set by transferring the predetermined friction-engaging device into an engaging state without sliding. The hydraulic control device comprises an exhausted pressure changeover mechanism 60 for supplying exhausted pressure following the other control that occurs when the predetermined transmission state is set by transferring the predetermined friction-engaging device B1 into the sliding state to a frictional surface of the predetermined friction-engaging device.

摘要： PROBLEM TO BE SOLVED: To provide a control device in which a set range and a driving state an not contradictory to each other, even if a fail is generated in control mechanism for engagement pressure in a hybrid drive unit connected with a plurality of power sources. SOLUTION: In the hybrid drive unit, of which gear mechanism is connected with a plurality of power sources, and which can set ranges of forward traveling, backward traveling and stop depending on an engagement/release state of engagement elements B1, C1, C2, a range selector valve 30 is provided. The range selector valve 30 changes over among a plurality of routes and outputs to the passages the original pressure that operates correspondingly to each of the set ranges to engage the engagement elements B1, C1, C2. In a state where the stop range is set, the range selector valve 30 outputs fluid pressure to the engagement element that establishes a transmission route for torque from one of the power sources to the other power source, and shut off the supply of the original pressure to the engagement element engaged in which torque is generated in an output member.

摘要： PROBLEM TO BE SOLVED: To realize a smooth jumping speed change by releasing an engaged clutch before speed change, while engaging a released clutch before speed change and establishing a speed step of one step lower speed side, when a jumping speed change from the speed step being used at present to two steps different speed step is required at a twin clutch type transmission. SOLUTION: During accelerating, when for example, a jumping speed change from a fourth speed step to the speed step of two steps lower speed side is required, in a control unit 100, an engaged clutch C2 before speed change is released, while a released clutch C1 before speed change is engaged. Thereby, a drive force transmitted from the speed step before speed change by the speed step of the one step lower speed side is increased. After judging that a drive force exceeds the rotation load in a transmission increased by the speed change from the speed step before speed change to the speed step of two steps lower speed side by the speed step of one step lower speed side, the gear engagement for speed step of two steps lower speed side is completed and thereafter, the engaged clutch C2 before speed change is engaged again and the released clutch C1 before speed change is released again.
