摘要： A conduit seal is provided for sealing a passageway in an automotive transmission. The transmission has an oil passageway and a member covering the passageway. The passageway is in fluid communication with a clutch. A bore communicates oil from the passageway to a passageway provided in the clutch. An annular seal is sealingly engaged with the bore of the case and the clutch to provide a fluid conduit therebetween. A compliant member is provided between the annular seal and the cover member to axially urge the seal into sealing engagement with the outer surface of the clutch.

摘要： A hydraulic load power train control for reversible shifting with a pressure control device for the controlled build-up of a shift clutch pressure, a foot clutch valve for arbitrary control of the shift clutches, and a manually operable shift valve for shifting of the reversible power train. The foot clutch valve is connected parallel to the pressure control device. The pressure control device is formed by a changeover valve indirectly reversible by the shift valve by which the pressure controlled in the supply pressure line can be fed to two shift pressure lines which are connected to a valve device. At the same time, the valve device is so controlled by the foot clutch valve that the effective shift clutch pressure can be controlled without influencing the position of the changeover valve as a function of the actuation of the foot clutch. The hydraulic load power train control, on the one hand, makes possible, in the case of engaging or reversing of the shift clutches, a smooth transition from one gear to the other and, at the same time, a delay-free start in the shifting by actuation of the foot clutch.

摘要： A shut off control system for the fluid activated clutches of a transmission is provided. The inventive control valve automatically shuts off hydraulic flow to the clutches whenever the engine of the vehicle is turned off. When the vehicle is restarted the clutch pedal must be depressed and released before fluid can again activate the clutches. With the inventive control system, the vehicle can be started in any gear but the vehicle will not move until the clutch pedal is depressed and released by the vehicle operator.

摘要： A combination range and master clutch assembly includes a separator plate, at least one clutch, a fluid actuated main piston for engaging each clutch, and at least one fluid actuated accelerator piston. The separator plate and main piston define first and second main chambers in communication with each other. The main piston and each accelerator piston define an accelerator chamber. Sliding of each accelerator piston blocks communication between the main chambers. The assembly is controlled by providing fluid at an operating pressure which may be modulated between low and high pressures. Fluid is selectively delivered to an accelerator chamber at the operating pressure when it is below a threshold pressure level, and to both the accelerator chamber and its associated main chamber at the operating pressure when it is above the threshold pressure level.

摘要： A control device for a hyudraulic friction clutch for a motor vehicle, wherein a piston is moved by a pressurized fluid supplied to a pressure chamber, to effect frictional engagement between driving and driven rotary members, and a proximity shut-off valve is disposed in the piston, for permitting the fluid to be discharged from the pressure chamber through a discharge passage when the piston has reached a ready-to-operate position from which the piston is moved to start the frictional engagement. The control device includes a hydraulic pressure source generating a predetermined line pressure, a pressure adjusting device for adjusting the line pressure to a controlled clutch pressure, a clutch control valve for applying the controlled clutch pressure to the pressure chamber to advance the piston for effecting the frictional engagement of the rotary members, and a controller for commanding the pressure adjusting device to adjust the line pressure to a predetermined lower level, when the controller commands the clutch control valve to supply the pressurized fluid to the pressure chamber for moving the piston to the ready-to-operate position. Thus, drag due to partial engagement of the clutch with the piston at the ready-to-operate position is minimized or eliminated.

摘要： The transmission control for a vehicle hydraulic transmission includes a sequence control valve that includes a shuttle valve and an interconnected sequence valve which are connected with speed and direction clutches of the transmission. The shuttle valve senses the drop in pressure in the direction clutches when they are shifted to actuate the sequence control valve to initially dump the speed clutch and then to keep that clutch disengaged until the direction clutch has fully re-engaged.

摘要： Hydraulic controls in a transmission for engaging a clutch for the F-R, or forward or reverse, direction before a clutch for first, second, or third speed. Flow of hydraulic fluid to each direction clutch and to each speed clutch is by way of a reducing valve which modulates fluid pressure in controlled way by throttling the flow. After the power unit for the clutch for the F-R clutches and the power unit for the clutch for first, second or third speed are filled with fluid by the reducing valve, pressure in the power units is then slowly raised by the valve linearly toward its maximum; for this purpose the hydraulic controls are supplied by a single source of hydraulic fluid and operate therefrom to provide a pair of modulated pressure outputs which are maintained with varying differences throughout their range of operation, and which operate the selected one of the F-R clutches and the selected one of the first second or third clutches. The F-R clutches are the ones which receive the higher modulated pressure output and which are constructed, proportioned in size, and arranged to have a higher speed capability and smaller energy absorbing capacity in their design, and they operate so as to be fully hydraulically engaged at the higher pressure output, and hence slightly before, the speed clutches.

摘要： A control apparatus for selectively operating any one of at least three fluid pressure operated devices at any given time. The control system includes first and second valves arranged in combination with each other and which are hydraulically interposed between a fluid pressure source and each of the fluid operated devices. Each valve is shiftable between first and second positions. Hydraulic logic circuitry selectively connects the first valve to the fluid operated devices and selectively connects the second valve to the first valve whereby, for any one position of the two valves, only one of the fluid operated devices is connected to the fluid pressure source while the remainder of the fluid operated devices are open to exhaust. First and second ON/OFF solenoid operated valves facilitate positioning of the first and second valves in response to electrical signals received by the ON/OFF valves.

摘要： A method and apparatus for increased clutch capacity in an automatic vehicle transmission having a nested clutch pair. An electronic control unit controls a pulse width modulator which applies control signals to the actuating solenoid valves of the nested pair of clutches. The electronic control unit operates to reduce the pressure on an engaged clutch of the pair during the period of time that the other clutch is being actuated during the shift. Once the shift is completed, the operating pressure on the previously engaged clutch is restored to a normal operating pressure. Provisions are also made for assuring that the period of time required for the shift is maintained between threshold limits or within a window of time. This adaptive feature precludes excessively short or long shifts.
