摘要： PROBLEM TO BE SOLVED: To provide a clutch unit of an automatic transmission which is compact in axial direction. SOLUTION: The automatic transmission is adapted to overlap a third clutch C3 and a four clutch C4 including hydraulic servos 20, 40 and cancel oil chambers 28, 48, respectively, in axial direction and then to dispose in position distinct from radial direction. A cancel plate 25 composing the cancel oil chamber 28 of the third clutch C3 is fitted on a stepped part 53 of a clutch drum of the four clutch C4 while simultaneously a cancel plate 45 composing the cancel oil chamber 48 of the four clutch C4 is disposed to prevent removal by a snap ring 30. Since a return spring 26 arranged in the cancel oil chamber 28 of the third clutch C3 is large in urged force as compared with a return spring 46 arranged in the cancel oil chamber 48 of the four clutch C4, a clutch drum 42 of the four clutch C4 is positioned by always abutting to a snap ring 50.

摘要： PROBLEM TO BE SOLVED: To eliminate a feeling of two-stage speed change by continuously forming progress of speed change in achieving speed change by controlling engagement and release of four engagement elements in two stages. SOLUTION: In an automatic transmission, desired speed change is achieved by pre-stage speed change of releasing a first engagement element B-1, and engaging a third engagement element C-1, and post-stage speed change to release a second engagement element C-2, and engaging a fourth engagement element C-3. A control device sets estimated rotation acceleration ω 0 of an input shaft of a transmission in accordance with input torque and input rotation acceleration, and controls release of the second engagement element C-2 for transition to the post-stage speed change in accordance with that. Change of input rotation (engine rotation) in transition from a pre-stage to a post-stage is thus continuously formed to prevent slower speed change generated between the stages.

摘要： PROBLEM TO BE SOLVED: To prevent a shift range different from a shift range set for a fail-safe from being achieved when a signal fail is generated. SOLUTION: A first oil pressure rise delay member to delay start-up of oil pressure acting on a first signal oil pressure chamber is disposed on an oil passage L-81 to supply first signal oil pressure to the first signal oil pressure chamber. A second oil pressure rise delay member having smaller start-up delay effect for oil pressure than the first oil pressure rise delay member is disposed on an oil passage to directly supply the other signal oil pressure to the other signal oil pressure chamber, or supply the other signal oil pressure to the other signal oil pressure chamber. Since flow of oil in the oil passage L-81 is restricted, an oil pressure disconnection is held when a signal fail is generated. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control device of an automatic transmission structured so as to easily remove air mixed in working oil in an oil passage from a modulator valve to a linear solenoid valve.
SOLUTION: This hydraulic control device 1 of an automatic transmission has: the modulator valve 2 for outputting line pressure PL as reduced modulator pressure; and the linear solenoid valve 3 for outputting the modulator pressure fed from the modulator valve 2 as control oil pressure corresponding to an electric signal. An orifice 12 opened to the outside of the hydraulic control device communicates with the oil passage 8 between the valves 2 and 3. Thereby, even if the air is mixed in the working oil for making the line pressure act, the air is easily exhausted from the working oil through the orifice 12, and the modulator pressure is properly made to act on the solenoid valve 3 by the working oil with the air removed.

摘要： PROBLEM TO BE SOLVED: To provide an automatic transmission having axially compacter construction while preventing its radial size increase due to arrangement interference between a rotation supporting member of a counter shaft and a seal ring.
SOLUTION: The annular seal ring c3, which is arranged between a seal face 71a of an oil pump device 70 and a hollow hole 5b of a partition wall 5a, is formed to pass between a roller bearing 82 of the counter shaft 81 and an oil pump unit 70A and to be located eccentric from a center axis X of an automatic transmission mechanism to the opposite side to the counter shaft 81. Thus, as compared with the case that the seal face and the hollow hole are arranged concentric with the center axis of the automatic transmission mechanism, a portion expanded into a falcated shape A can be formed and an oil path a11 can be arranged to pass the expanded portion.
