摘要： PROBLEM TO BE SOLVED: To compact and reduce the weight and a cost of an automatic transmission through reduction of the number of parts and the number of processes and to improve reliability of operation and durability of a one-way clutch. SOLUTION: A step part 25 is formed between first and second grooves 23 and 24 on the inner peripheral side of a case 15. The outer lace 22 of a second one-way clutch F2 is fitted in a first spline groove 23. The front end thereof is regulated axially frontward by a snap spring 26 and the baffle plate 27 of a third brake B3 is regulated axially rearward. Further, the baffle plate 29 of the second brake 2B is regulated axially frontward by the step part 25, and the rear end of an outer lace 22 is regulated axially rearward by the baffle plate 29. Further, the two baffle plates 27 and 29 are also additionally functioned as the retainers of return springs 28 and 30. This constitution reduces a cost through reduction of the number of parts and the number of processes, and further performs reliable operation of the one-way clutch F2 and improves durability.

摘要： PROBLEM TO BE SOLVED: To improve the yield of a material without deteriorating the function of a frictional engaging element. SOLUTION: A first clutch C1 and a third brake B3 with good frictional characteristics and large torque capacities and heat capacities are combined together, a second clutch C2 and a second brake B2 with a similar speed change patterns to each other and large heat capacities are combined together and a third clutch C3 and a first brake B1 requiring frictional characteristics and controllability to some degree are combined together. Each disk or each separator plate of the combinations is formed with one common material on the basis of a set membership. Thus, the yield of the material can be improved without deteriorating the original functions of each clutch and each brake.

摘要： PROBLEM TO BE SOLVED: To improve the strength of pressed components of an automatic transmission only at their necessary portions without deteriorating press-working productivity. SOLUTION: An annular plate member 5, which is adapted to be engaged with a locking part 7 placed around a shaft-shaped member periphery 10 against axial movement so as to hold an axial load on its plate face, has a reinforcement part 55 connecting to the end to be engaged with the locking part 7. This reinforcement part 55 is made up of a part 55b extending axially from an engagement part 55a to be coupled to the locking part 7, and a turned-back part 55c turned back to extend the counter direction.

摘要： PROBLEM TO BE SOLVED: To reduce the generation of a thrust force exerted on a specified through bearing, decrease the number of seal rings, and compact an automatic transmission and improve machine efficiency. SOLUTION: When a transmission is in a forward speed, a thrust force to a rear generated by a gear set is supported by a thrust bearing 25 through an input shaft 2. Further, high pressure hydraulic oil is introduced to the hydraulic servo 32 of a clutch C1, engaged at a low speed except a forward maximum speed, through the axial hole 31 of the rear end part 2a of the input shaft 2 and a radial hole 34. At a forward low speed, since a high oil pressure of hydraulic oil is exerted on the rear end face 2d of the input shaft 2, a force generated by the oil pressure is exerted on the input shaft 2 always in opposition to a thrust force to a rear and a thrust force supported by the bearing 25 is reduced by an amount equivalent to a force generated by the oil pressure. Further, since hydraulic oil is introduced through the axial hole 31 and the radial hole 34 of the input shaft 2, a single seal ring 36 suffices for sealing. This constitution compacts an automatic transmission A and improves machine efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control device capable of avoiding occurrence of a rapid deceleration state in a belt type continuously-variable transmission without adding a new solenoid valve. SOLUTION: The hydraulic control device is equipped with a fail-safe valve 305 capable of switching hydraulic pressure to be supplied to a primary pulley 41 between output hydraulic pressure of a gearshift hydraulic pressure control valve 301 and hydraulic pressure different from the output hydraulic pressure. The fail-safe valve 305 is switched to a fail position for supplying the different hydraulic pressure to the primary pulley 41 when there is possibility that a rapid deceleration state will occur, and is otherwise switched to a normal position for supplying the output hydraulic pressure of the gearshift hydraulic pressure control valve 301 to the primary pulley 41. The switchover of the fail-safe valve 305 is controlled by control hydraulic pressure of an ON-OFF solenoid (SL) 204 and control hydraulic pressure of a duty solenoid (DSU) 203.

摘要： PROBLEM TO BE SOLVED: To make the whole of an automatic transmission more compact and improve the ability of the transmission to be mounted on a vehicle by shortening the shaft length of the second shaft, and bringing the second shaft close to the first shaft as much as possible. SOLUTION: The small capacity second clutch C2 which is not engaged when it is retracted, is arranged in front of a counter drive gear 16, the remaining large capacity first and third clutches C1, C3, and the first and third brakes B1 to B3 are arranged in the rear of the counter drive gear 16, and a space δ' is formed in the axial direction between the counter drive gear 16 and the second clutch C2. A parking gear 22 is arranged in this space δ. Thus, the parking gear 22 can approach a countershaft 3 by an input shaft without interfering with the second clutch C2, and an automatic transmission A can be made more compact. Further, since the need for moving the counter drive gear 16 in the rear, is eliminated, the shaft length of the countershaft 3 can be shortened, and the automatic transmission A can be made further compact.

摘要： PROBLEM TO BE SOLVED: To form a planetary gear unit compactly in both the axial and radial directions and reduce its weight while the machining accuracy of pinion shaft holes is ensured in good condition. SOLUTION: A carrier CR is made to be a one-piece structure having the first and second flange parts 24, 25 supporting a long pinion P and a short pinion P1, and the machining accuracy of pinion shaft holes is ensured in good condition. An inner race 37a is connected to a connection part 26 provided at the carrier CR so that it is positioned within the width in the axial direction of the long pinion P, in parallel with a ring gear R1 by a fastening member 39. The outer peripheral surface 26a of the connection part 26 is structured to be a spigot-fitting part onto which a rotary engaging member 37 is fitted. A short pinion shaft 32 is arranged inside a long pinion shaft 30, and the fastening member 39 is arranged in the vicinity of the short pinion shaft 32. Thus, the planetary gear unit 12 becomes compact in both the axial and radial directions.

摘要： PROBLEM TO BE SOLVED: To provide a liquid flow path structure with a pressure regulating valve in a liquid flow path for well suppressing the generation of unpleasant abnormal sounds when regulating pressure in the liquid flow path structure. SOLUTION: The liquid flow path structure 13 with the pressure regulating valve 15 comprises a gas storage chamber 24 provided in a corner part 27 formed in a connection joint 19 located on the downstream side of the pressure regulating valve 15 for functioning as a vibration suppressing part. The gas storage chamber 24 is arranged at a position where ATF flowing from the upstream side into the corner part 27 collides. Pressure pulsation propagated together with the flow of the ATF is damped by the damper effect of the gas storage chamber 24. COPYRIGHT: (C)2008,JPO&INPIT
