摘要： During transmission shifts, a band brake is used in either a self-loosening direction in which an engaging force thereof is not sensitive to variations in hydraulic pressure or a self-tightening direction in which the engaging force is sensitive to variations in hydraulic pressure. In the self-loosening direction, a second regulated hydraulic pressure generated by a second pressure regulating valve (B-4 control valve) in accordance with a control hydraulic pressure generated by a second (throttle-pressure-control) linear solenoid valve in a margin control region thereof is supplied to a hydraulic servo of the fourth brake (band brake). In this clutch-to-clutch shift, a first regulated hydraulic pressure generated by a first pressure regulating valve (a shift-pressure control valve) in accordance with a control hydraulic pressure generated by a first (pressure-regulation) linear solenoid valve is supplied to a hydraulic servo of a third (UD direct) clutch. In the self tightening direction, the first regulated hydraulic pressure generated by the first pressure regulating valve (the shift-pressure control valve) is supplied to the hydraulic servo of the fourth brake (band brake).

摘要： A control system for an automatic transmission operates a clutch for disengaging a transmission mechanism when a vehicle is stopped and idling with the brake pedal depressed while the gear shift is in a forward gear. The clutch is maintained at a drag state (friction elements disengaged but oil causing some torque transmission) bordering a slip state (friction elements engaged) When a neutral control is started, the clutch is released until the retraction of the piston of the hydraulic servo is started. When the rate of change in a rotational difference does not exceeds a reference rate of change even after a set time has elapsed, booster means of specific release state holding means decides that the clutch is in a drag region, and raises an oil pressure to be fed to the hydraulic servo, by a set pressure. On the other hand, when the rate of change exceeds the reference rate and the rotational difference increases, irrespective of the lapse of a set time, the first pressure reducing means of the specific release state holding means decides that the clutch is in a slip region, and lowers the oil pressure to be fed to the hydraulic servo, by a set pressure. As a result, the clutch is always held in a state which is immediately before the transfer from the drag region to the slip region.

When the rotational speed change .DELTA.N of the input rotation becomes a rotation change start-determining rotational speed dN.sub.S, the control apparatus feedback-controls the hydraulic pressure with a predetermined gradient while referring to the input rotation change. Further, the control apparatus detects the target shift start time and the rotational speed change rate at the target shift start time to correct the target hydraulic pressure P.sub.TA, the gradient .delta.P.sub.TA of the second sweep section, and the target shift start time t.sub.aim.

摘要： A control system for control of a clutch interposed between a fluid transmission unit and a speed change unit in a vehicular automatic transmission. The control system includes a first R.P.M. detector for detecting clutch input side R.P.M. and a second R.P.M. detector for detecting clutch output side R.P.M. A stop state detector determines if the vehicle is at a standstill and a starting operation detector detects a starting operation by the driver. The hydraulic control unit includes a hydraulic servo for applying/releasing the input clutch, a control signal oil pressure generating solenoid valve for generating a control signal oil pressure, a control valve for regulating a forward running range pressure according to the control signal oil pressure to generate a control oil pressure; a change signal oil pressure generating solenoid valve for generating a change signal oil pressure and a change-over valve switchable by the change signal oil pressure, between a first position in which it feeds the forward running range pressure to the hydraulic servo, and a second position in which it feeds the control oil pressure to the hydraulic servo. A failure is decided if the clutch input/output R.P.M. difference is over a set value which is set on the basis of the clutch input/output R.P.M. difference when the starting operation is detected by the starting operation detector. A fail-safe feature causes a shift output to a higher speed gear stage, over-riding a control signal from the pressure booster, when a failure is decided, to output the change signal to the solenoid of the control signal oil pressure solenoid valve to thereby bring the change-over valve into the first position.

The control system includes a clutch which is applied responsive to selection of forward running range; a one-way clutch which is locked, when the clutch is applied, to establish a forward first speed; a brake for locking the one-way clutch, to block reverse rotation of the output shaft of the speed change unit. First and second hydraulic servos apply, respectively, the clutch and the brake responsive to receipt of oil pressures. A control unit controls the oil pressures fed to the first and second hydraulic servos. The control unit starts the feed of oil pressure to the second hydraulic servo responsive to selection of a forward running range, provided the vehicle is substantially stopped, the engine is idling and the foot brake is engaged. The control unit starts the reduction of the pressure of the first hydraulic servo upon expiration of a set time period and starts transition of the clutch from the applied state to the slipping state of the clutch upon completion of the piston stroke of the second hydraulic servo which applies the brake.

摘要： In a hydraulic torque converter having a torus of flatness ratio (L/H) within the range 0.82-0.9, the outer and inner contours of the turbine in a meridional plane through the axis of the turbine each comprises a combination of a plurality of circular arcs, wherein the ratios between the radii of the circular arcs constituting said outer contour is substantially less than 2, and the ratios between the radii of the circular arcs constituting said inner contour is substantially less than 2.As a result, fluid flows through the turbine stably without being biased, increasing the velocity of relative flow along the turbine blade, and raising the normal speed ratio at which the absolute flow is in the direction of no impact, enabling a higher stall torque ratio without reduction in efficiency.

The vehicular automatic transmission is equipped with a planetary gear set that receives a decelerated rotation and a non-decelerated rotation as inputs and outputs a plurality of speed-change rotations, a reduction planetary gear, an input shaft that passes through an inner side of the planetary gear set, first and third clutches that couple the input shaft to two different speed-change elements of the planetary gear set respectively through the reduction planetary gear in an engageable and disengageable manner, and a second clutch that couples the input shaft to the other speed-change element of the planetary gear set in an engageable and disengageable manner. The reduction planetary gear and the third clutch for transmitting a high torque are arranged on one side of the planetary gear set, whereas the first clutch for transmitting a high torque is arranged on the other side of the planetary gear set.

摘要： An automatic transmission comprises a reduction planetary gear, two clutches transmitting a decelerated rotation transmitted from the reduction planetary gear, and a planetary gear set comprising two elements to which the decelerated rotation is inputted through the two clutches. The reduction planetary gear and the two clutches are arranged in one side of the planetary gear set. The second clutch is closer to the planetary gear set than the clutch. The input side member of the first clutch is connected to an output element of the reduction planetary gear and the input side member of the second clutch. The output side member of the first clutch is extended through the radial inner space of the second clutch and connected to one of the two elements of the planetary gear set. Thus, no member is arranged in the radial outer side of the both clutches, and the both clutches are radially enlarged.
摘要翻译：自动变速器包括减速行星齿轮，传递从减速行星齿轮传递的减速旋转的两个离合器和包括通过两个离合器输入减速旋转的两个元件的行星齿轮组。减速行星齿轮和两个离合器布置在行星齿轮组的一侧。第二离合器比离合器更靠近行星齿轮组。第一离合器的输入侧构件连接到还原行星齿轮的输出元件和第二离合器的输入侧构件。第一离合器的输出侧构件延伸穿过第二离合器的径向内部空间并且连接到行星齿轮组的两个元件中的一个。因此，在两个离合器的径向外侧没有配置构件，并且两个离合器都径向扩大。
