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： 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： 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.

摘要： In a hydraulic servo for a clutch, a cancel plate is disposed on a second clutch drum that undergoes the same rotation as a second clutch drum provided with a cylinder portion, in such a fashion that the cancel plate is restricted from moving to a side opposite from a return spring in an axial direction. The first clutch drum is disposed, as a separate member, on the second clutch drum. A step portion of the second clutch drum prevents the first clutch drum from moving to a side opposite from the cancel plate. Due to the spring force of the return spring, the oil pressure in the cancel oil chamber and the oil pressure in the operating oil chamber, the force that presses the first clutch drum to the step portion is always greater than the force that presses the first clutch drum to the cancel plate side.

摘要： At a first forward speed, the oil passage in a relay valve is switched to control the torque capacity of a lock-up clutch using a linear solenoid valve that controls the engagement pressure of a clutch that is engaged at each of fifth to eighth forward speeds. At each of second to eighth forward speeds, the oil passage in another relay valve is switched to control the torque capacity of the lock-up clutch using a linear solenoid valve that controls the engagement pressure of a brake that is engaged at the first forward speed.

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.
