摘要： An oil seal member is compressed between a connecting pipe for supplying oil to an oil chamber of a hydraulic servo and the cylinder drum of the hydraulic servo. The cylinder drum has an interior oil chamber and turns through a predetermined angle upon operation of a frictional engagement element by the hydraulic servo. The end of the seal member pressed against the cylindrical drum surrounds an oil hole 73 formed in the cylindrical drum, and oil pressure is supplied to the oil chamber through an oil passage in which the seal member is mounted and through the oil hole. A recess is formed in the outer surface of the cylindrical drum around the oil hole and the end of the seal member is received in the recess. When the cylindrical member turns within the predetermined angular range, the end of the seal member is protected by the recess. As a result, the end of the seal member is not damaged and the integrity of the seal is protected.

摘要： It is intended to prevent generation of noise and shock when a parking range is released after a vehicle has been parked so that a driver does not feel uncomfortable. A parking apparatus of an automatic transmission has a parking gear (16); a parking pole (17) swingably disposed and provided with a claw (18) arranged to selectively be engaged with a tooth space (22) of the parking gear (16); engagement inhibition means movably disposed and arranged to be moved to an inhibition position for inhibiting engagement between the claw (18) and the tooth space (22) and to an inhibition release position for releasing the inhibition of the engagement; and engagement inhibition release means for moving the engagement inhibition means to the inhibition release position in synchronization with the rotation of the parking gear (16). After a residual torque existing between the parking gear (16) and drive wheels has been released, the claw (18) and the tooth space (22) are engaged with each other.

摘要： An oil pressure controller of an automatic transmission which is capable of supplying engaging pressures to hydraulic servos of two frictional engaging elements which require different engaging pressures by a single pressure governing valve with a good pressure governing accuracy. The oil pressure controller comprises a hydraulic power source 10, hydraulic servos 70 and 80, signal pressure generating means 20, a pressure governing valve 30 for governing an oil pressure (Ps) from the hydraulic power source 10 by a signal pressure (PACC) and a control valve 40. The pressure governing valve 30 has a pressure receiving face A1 to which the signal pressure is applied, a pressure receiving face A2 to which the engaging pressure (Ps) is fed back in the opposite direction and a pressure receiving face A3 for selecting whether the feedback of the engaging pressure is present or not in order to change the control gain of the pressure governing valve 30 in response to the change of the control valve 40 for selecting the hydraulic servo 70 or 80 to which the oil pressure is supplied.

摘要： A hydraulic control system for an automatic transmission comprising: a frictional engagement element (B-3); a hydraulic servo (28) for controlling the application/release of the frictional engagement element (B-3); an oil passage (201) connected to the hydraulic servo (28) for feeding/releasing an oil pressure to the hydraulic servo (28); a pressure regulator valve (25) disposed in the oil passage; and signal pressure generating means (SLU;...) for applying a signal pressure to the pressure regulator valve (25). The oil passage (201) includes: a first oil passage (201d) for feeding the oil pressure to the pressure regulator valve (25); and a second oil passage (201e) for feeding the oil pressure from the pressure regulator valve (25) to the hydraulic servo (28). The pressure regulator valve (25) includes: a valve member (250); an input port (254) connected to the first oil passage (201d); an output port (255) connected to the second oil passage (201e); and a drain port (257) connected to a drain oil passage (EX). The valve member (250) has: a first pressure receiving area (A₁) to be fed with the feedback pressure of the second oil passage (201e) in a direction to provide the communication between the output port (255) and the drain port (257); a second pressure receiving area (A₂) to be fed with the signal pressure (P SLU ) in a direction to provide the communication the output port (255) and the drain port (257); and a third pressure receiving area (A₃) having an area different from that of the second pressure receiving area (A₂). The signal pressure generating means (SLU;...) feeds the signal pressure to the third pressure receiving area (A₃) at all times and the signal pressure (P SLU ) selectively to the second pressure receiving area (A₂).

摘要： PROBLEM TO BE SOLVED: To eliminate a sense of incompatibility when shift-down is caused by failure in an engine brake attaining condition. SOLUTION: An oil pressure control device has a directional control valve 2 to supply-discharge oil pressure of frictionally engaging elements B-1 and B-3 for an engine brake, a first solenoid valve S3 to output switching signal pressure to it, a second solenoid valve S4 to output switching signal pressure different between a prescribed shift stage and the other shift stage time and a control valve 8 to impress output signal pressure of the second solenoid valve S4 on the directional control valve 2 at shift-down time to the prescribed shift stage under oil pressure supply to the frictionally engaging element B-1 by the directional control valve 2. At shift-down time to the prescribed shift stage from the other shift stage by fail, oil pressure is discharged from the frictionally engaging element B-3 by switching the directional control valve 2, and attainment of an engine brake condition is avoided by releasing it.

摘要： PROBLEM TO BE SOLVED: To surely carry out sufficient lubrication to an engagement element and to reduce machining man-hours. SOLUTION: A ring type side plate part 4a in a brake hub 4 is connected to the left end of an outer race 3. In the position, with which the left end of the outer race 3 is brought in to contact, in the ring type side plate 4a, a recess part 4c connecting the inner circumference side to the outer circumference side of the outer race 3 is formed. Therefore, in a rotary shaft 1 during its rotation, lubrication oil fed to the axial directional lubrication oil passage hole 1a in the rotary shaft 1 is let flow via a diameter directional lubrication oil passage hole 1b and a lubrication oil passage hole 2a by means of centrifugal oil pressure toward the inner circumference side of the outer race 3, and then, passes the recess part 4c and flows along the ring type side plate part 4a so as to be let flow toward friction plates 5, 7 via a lubrication oil passage hole 4e in a cylindrical part 4b in the brake hub 4. As the recess part 4c is formed in the ring type side plate part 4a, a lubrication passage area can be increased while welding is facilitated, and as a result, machining man-hours can be reduced.
