摘要： A hydraulic servo for a brake in an automatic transmission has a piston secured against rotation without provision of a protrusion on the piston engaging the transmission casing. The piston of the hydraulic servo has an inner cylindrical surface configured to grasp, along their lengths, return springs compressed between the piston and a return plate to which the return springs are fixed. The return plate is bolted to a bulkhead portion of the transmission case and, thus, the piston member is fixed to the bulkhead portion and thereby prevented from rotating.

摘要： At the time of a failure in the second group of engagement devices, the manner of input of oil pressures to a fail-safe valve group is changed via a priority degree switching valve on the basis of the state of engagement of engagement devices of the first group in such a manner that the predetermined degrees of priority for the supply of one of oil pressures PC4, PB1 output from linear solenoid valves SL4, SL5 to a corresponding one of a clutch C4 and a brake B1 via the fail-safe valve group are changed so as to avoid an event that the fail-safe gear stage established in order to prevent the occurrence of interlock of the automatic transmission involves a downshift of two or more stages from the speed change stage maintained immediately prior to the occurrence of the failure. Therefore, it is possible to prevent the occurrence of an uncomfortable behavior of the vehicle caused by the shift to the fail-safe gear stage.

摘要： The present invention provides an automatic transmission having a main bearing disposed between the inner surface of a boss portion of a first drum and the outer surface of a cylindrical support, for rotatably supporting the first drum. An auxiliary bearing is press-fit into one end of the interior of the boss portion of the first drum and surrounds the cylindrical support with an annular gap therebetween. The auxiliary bearing contacts the cylindrical support only when the first drum tilts relative to the central axis of the transmission, and has a shorter axial length than that of the main bearing.

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.

摘要： A hydraulic control system that includes a solenoid valve for supplying a prescribed fluid pressure; and a relay valve for selectively switching a destination of the prescribed fluid pressure between a first destination part and a second destination part. The relay valve has an input port supplied with a normally produced fluid pressure and an output port that selectively communicates with the input port. The hydraulic control system further includes a fluid pressure switch, provided in the output port of the relay valve, that is activated when the input port communicates with the output port to allow the normally produced fluid pressure to be supplied to the output port.
