摘要： A direct coupling clutch controller interposed between a direct coupling clutch in a torque converter of an automatic transmission and a hydraulic pressure source for temporarily disconnecting the direct coupling clutch whenever the transmission shifts gears. The controller is particularly suitable for transmissions having four or more gear stages, and includes a valve having a first and a second switching position where the pressure source is connected to the clutch. As the valve moves between the positions, the connection is interrupted. The valve is pilot operated by the transmission controller.

摘要： An automatic transmission has lower side and higher side friction engagement devices, with the lower side one being engaged and the higher side one being disengaged when a lower speed stage is engaged, while the lower side one is disengaged and the higher side one is engaged when the speed stage one higher than that lower speed stage is engaged. A control device for the transmission includes a shift valve for switching actuating fluid pressure between the lower side and the higher side friction engagement device and for draining the other one thereof, to provide the lower or the higher speed stage. An upshift smoothing valve is interposed in the drain path for the lower side friction engagement device for providing a higher flow resistance when a value representing engine output is relatively high and for providing a lower flow resistance when the value representing engine output is relatively low. Thus upshifting shock is reduced, particularly under low engine output conditions, in which overlapping of the engagement of the lower side and the higher side friction engagement devices is reduced. Optionally, the upshift smoothing valve may provide its higher or lower flow resistance, according as to whether the value representing engine output prevails over the actuating pressure for the higher stage friction engagement device, in a relationship between them, or not.

摘要： A control device for controlling the operation of a direct-coupling hydraulic clutch of a hydraulic torque converter for use in an automotive vehicle, wherein the hydraulic torque converter is coupled to a transmission of the automotive vehicle selectable at a plurality of transmission gear ratios. A first fluid line is connected to the direct-coupling hydraulic clutch for supplying same with operating fluid pressure generated by an operating fluid pressure source. A selector valve is arranged across the first fluid line and shiftable to a first or a second position thereof in response to a transmission gear ratio established by the transmission, and is adapted to open the first fluid line when it assumes the first or second position, and to close the first fluid line when it assumes a third position between the first and second positions. A second fluid line branches off from the first fluid line at a location between the selector valve and the direct-coupling hydraulic clutch and communicates with a zone under lower pressure, and across which the selector valve is arranged. The selector valve has a valve operable to close the second fluid line when the first or second position is assumed, and to open the second fluid line to thereby escape operating oil pressure to the zone under lower pressure when the third position is assumed. Preferably, at least one restriction is arranged in the first fluid line at a location between the junction of the first and second fluid lines and the operating fluid pressure source.

摘要： In an automatic transmission for a vehicle, a lock-up device is provided for a direct coupling clutch. The automatic transmission includes a fluid type torque converter having a hydraulic direct coupling clutch, and an auxiliary transmission having plural stages of gear trains. The lock-up control device has a valve for controlling the supply of oil pressure from a common oil pressure source to the direct coupling clutch, the valve having a body movable between opposite end positions and adapted to take a first switch position at one of the end positions when applied with a single signal pressure and a second switch position at the other end position, after release of the signal pressure, due to resilient force of a spring. The valve allows flow of the actuating oil pressure to the direct coupling clutch when the valve body is at both the first and second switch positions and interrupts the flow during shifting movement of the valve body from the first to second positions or vice versa. Thus, the direct coupling clutch is instantaneously disconnected during gear shifting operation over adjacent three gear ratios with use of the single signal pressure.

The control system is also provided with a switch valve for allowing the actuating oil to escape to an oil tank synchronously with the speed change operation, and a supplementary mechanism for performing a switching operation so as to raise the internal pressure of the torque converter synchronously with the speed change operation. There is further provided with a supplementary oil passage for supplementing pressurized oil to the torque converter and a switch device for allowing the actuating oil to escape to the oil tank and opening the supplementary oil passage when the throttle opening is at an idle position.

摘要： A direct-coupling control device for a torque converter for an automatic vehicular transmission in which a valve controlling the locking force of a direct-coupling mechanism is provided with two independently-formed pressure chambers pushing a valve body in a direction in which a locking force is increased. The device is also provided with a first fluid pressure output connected to one of the pressure chambers, and a second fluid pressure output connected to the other. When the first fluid pressure is higher than the second fluid pressure, the first fluid pressure acts on the sum of the individual working areas of the first and second fluid pressures on the valve body. A reliable speed change control can be provided by the two fluid pressures, and the capacity characteristics of the direct-coupling mechanism can be selected optimally with respect to these fluid pressures. The locking force of the direct-coupling mechanism can be increased quickly in proportion to increasing vehicle speed, and fuel costs can be reduced very effectively.

摘要： A direct-coupling controller for a torque converter direct-coupling clutch in an automatic transmission. The controller can include a feedback pilot oil pressure operated reduction valve with a throttling orifice in the signal line and a pilot oil pressure switched vehicle speed response valve in parallel with the reduction valve. The vehicle speed response valve bypasses the reduction valve when vehicle speed is above a predetermined value. Alternatively, the controller includes a single valve which is pilot oil pressure switched depending on vehicle speed which in an open position directly feeds oil pressure to the clutch and which in a closed position feeds the oil pressure to the clutch while throttling the oil pressure through an orifice and permitting some of the working oil to pass the drain through another throttling orifice.
