    摘要： A switch-over valve 6 is provided in a pressure circuit 31 between a hydraulic pump 2a and a clutch 7, and a pressure limiting valve 5 is provided between a reflux circuit 9 for the valve 6 and the pressure circuit 31. The clutch actuating hydraulic circuit includes another hydraulic pump 2b, and a switch-over valve 8 for switching over a discharged fluid of the hydraulic pump 2b. A downstream side of the switch-over valve 8 is connected to the pressure circuit 31 and to the reflux circuit 9. Consequently, when the clutch is engaged or disengaged, the discharged fluid of the hydraulic pump 2b is combined with the discharged fluid of the hydraulic pump 2a so as to increase the flow rate to the clutch 7.

    摘要： A pump coupling or hydraulic actuator controlling one or more limited slip couplings of a distribution system for distribution torque between front and rear axles in all wheel drive vehicles and/or distribution of torque between left and right wheels in two or four wheel drive vehicles. The hydraulic actuator includes an electric motor, a hydraulic pump, driven by a drive shaft of the electric motor, and the one or more limited slip couplings. Each limited slip coupling includes a disc package and a piston acting on the disc package, which piston is actuated by a hydraulic pump. A centrifugal regulator is connected to a rotating part of the electric motor or the hydraulic pump, which centrifugal regulator controls a pressure overflow valve, connected to the oil outlet of the hydraulic pump. The pressure is controlled by current to the electric motor or by control of the motor speed.

    摘要： A method of controlling a clutch pressure of a transmission which can be applied to a clutch of a large capacity piston volume, which has a short time lag for engaging the clutch, a uniform clutch engaging time and is inexpensive, and a control apparatus therefor. Accordingly, in a clutch pressure control apparatus of a transmission including a pressure control valve which supplies a discharge oil in a hydraulic pump to a clutch chamber at a time of engaging a clutch, whereby the clutch chamber is full of the discharge oil, gradually increases a hydraulic pressure in the clutch chamber after being filled so as to engage the clutch, and drains the oil in the clutch chamber to a tank at a time of disengaging the clutch, the apparatus is provided with a supply bypass valve which directly supplies the discharge oil of the hydraulic pump to the clutch chamber with bypassing the pressure control valve at a time of engaging the clutch, and a discharge bypass valve which directly drains the oil in the clutch chamber to the tank by bypassing the pressure control valve at a time of disengaging the clutch.

    摘要： A system for a four-wheel drive vehicle for automatically changing a power transmission system of the engine of the vehicle from four-wheel driving system to two-wheel driving system in accordance with the steering angle during the turning of a corner. The transmission system is provided for transmitting a power from the engine to main driving two-wheel, and a fluid pressure controlled friction clutch is provided for transmitting the power of the engine to two wheels other than the main driving two-wheel. A steering angle sensor is provided for producing a steering angle signal dependent on the steering angle. A control system is provided to respond to the steering angle signal for decreasing the pressure of the pressure oil applied to the clutch thereby to cause the slip of the clutch during the turning of the corner.
