摘要： A method of controlling the hydraulic pressure for an automatic transmission gear system, in which the actual rotation speed of a rotatable element during a speed shift from, for example, the 1st speed ratio to the 2nd speed ratio is detected, and the hydraulic pressure supplied to a frictional engaging element acting to change the rotation speed of the rotatable element is controlled so that the rate of change of the rotation speed of the rotatable element can converge to a predetermined change rate when the speed change rate due to the speed shift is ideal. On the other basis of the hydraulic pressure supplied to the frictional engaging element in the final state of the speed shift, the initial hydraulic pressure to be supplied to the frictional engaging element immediately after starting of the next speed shift is computed. Such a trial is repeated a plurality of times so that an automatic transmission whose operating hydraulic pressure is not primarily designed to meet the operation of an engine from the aspect of the capacity can be adapted to operate with the engine.

摘要： A power transmission includes two piston-type actuators for selectively engaging and releasing their associated clutches. Each of the actuators is designed in such a way that in order to compensate a centrifugal hydraulic pressure to be developed in a working fluid chamber by a remaining hydraulic fluid upon release of the clutch, a centrifugal hydraulic pressure chamber is formed on the side opposite to the working fluid chamber relative to a piston and a centrifugal hydraulic pressure equal to the centrifugal hydraulic pressure in the working fluid chamber is produced in the centrifugal hydraulic pressure chamber. A partition forming the centrifugal hydraulic pressure chamber also serves as a cylinder forming the working fluid chamber of the other actuator.

摘要： In an automatic transmission gear of 4-speed advance type comprising at least 3 pairs of clutches including a friction clutch which hydraulically connects an input shaft and the carrier of Ravigneaux type planet wheel gears for the 4th speed, 2 pairs of brakes and one pair of oneway clutches, it is required to engage two pairs of clutches in order to shift the speed to the 3rd speed while it is necessary to engage another pair of clutches with one pair of brakes for the 4th speed, thereby presenting difficulties in setting transmission timings and an initial engagement torque. The hydraulic control system for an automatic transmission gear according to the present invention is capable of smooth transmission without causing transmission shocks and of improving the durability of clutches and brakes because in the system one pair of clutches is made to engage for the 4th speed in advance after completion of the 3rd speed shifting.

摘要： Improvement in a hydraulic type automatic transmission including a fluid torque converter and a plurality of friction-engagement devices associated with hydraulic servo devices in which different speed change ratios including a plurality of forward movement steps can be realized by selectively actuating the friction-engagement devices with a hydraulic pressure either automatically or manually. Upon deceleration from a higher speed gear ratio to a predetermined gear ratio, a friction-engagement device for realizing the predetermined gear ratio is quickly engaged without delay, whereas upon acceleration from a lower speed gear ratio or a neutral condition to the predetermined gear ratio, engagement of the friction engagement device is effected slowly by actuating an accumulator and a flow rate limiter and thereby generation of an excessive shock is prevented.
