摘要： A planetary gear device having a first and a second single-pinion planetary gear unit and a third double-pinion planetary gear unit, which are coaxially disposed so as to provide different speed reduction ratios. The three gear units have respective first, second and third sun gears, respective first, second and third ring gears, and respective first, second and third carriers rotatably supporting planetary pinions. The first and second sun gears are fixed together or selectively connectable to each other, and the first carrier, second ring gear and third carrier are fixed together or selectively connectable to each other. Further, the second carrier and the third sun gear are fixed together or selectively connectable to each other. The present arrangement allows shifting operations of the gear device, without concurrent disengagement and engagement of different clutches.

摘要： A variable-displacement vane-pump has a rotor which is rotatably supported by a pump housing in coaxial relationship therewith, and a cam ring interposed between the rotor and the pump housing in eccentric relationship with the pump housing. The rotor has radially outwardly slidable vanes on its outer peripheral surface in contact with an inner surface of the cam ring. Two side plates are disposed on both sides of the vanes, thereby defining pump chambers between every adjacent vanes. An arc-shaped intake port and an arc-shaped exhaust port are formed in one of two side plates, and respectively open into the pump chambers along one side face of the cam ring. In the other side face of the cam ring, a groove is formed except for the region corresponding to the exhaust port, and a partially cut off annular friction ring is disposed within the groove while urged by a seal ring into close contact with the other side plate. A pressure compensating recess having a configuration which conforms to that of the exhaust port and communicating with the pump chambers is formed in the other side face of the cam ring except for the region wherein the groove for the friction ring is formed.

The first transmission unit has first and second intermediate transmitting paths through which a rotary motion of the input rotary member is transmittable to the second transmission unit such that a speed of the rotary motion transmitted through the second intermediate transmitting path is lower than a speed of the rotary motion transmitted through the first intermediate transmitting path. The second transmission unit constitutes first, second, third and fourth rotary modules, each of which is provided by at least one of sun gears, carriers and ring gears of two planetary gear sets. The first rotary module is selectively connected to the second intermediate transmitting path, while being selectively connected to the stationary member. The second rotary module is selectively connected to the first intermediate transmitting path, while being selectively connected to the stationary member. The third rotary module is connected to the output rotary member. The fourth rotary module is selectively connected to the first intermediate transmitting path, while being selectively connected to the second intermediate transmitting path.

摘要： In a hydraulic control apparatus for a vehicular automatic transmission, if it is determined that there is a failure that may cause tie-up in an automatic transmission, communication is provided between a first output port and a first drain port in a switching valve. As a result, a hydraulic frictional engagement device, which should be disengaged when there is a failure, is disengaged. Also, a specific shift speed is achieved by controlling the switching valve. Therefore, it is not necessary to select a shift speed that is achieved on the condition that the hydraulic frictional engagement device, which should be disengaged when there is a failure, is engaged. Thus, it is possible to prevent a shift that may impair driveability when there is a failure that may cause tie-up in the automatic transmission.

摘要： With the automatic transmission 10-1 for vehicle according to the present embodiment, since multistage transmission of eight forward gear stages can be obtained by means of four sets of planetary gear sets 12, 16, 18 and 20, four clutches C1 through C4 and three brakes Bi through B3, the transmission can be fabricated to be light in weight and made compact, wherein the mountability thereof in a vehicle can be improved. Further, as has been made clear in FIG. 1 (b), since speed change in the respective gear stages can be carried out only by a shifting action of any two of the clutches C1 through C4 and brakes Bi through B3, the speed change control can be facilitated and it is possible to prevent a shock to the transmission from occurring.
