    摘要: The present invention provides a driving force distributing apparatus which can instantaneously reduce clutch pressure to thereby carry out proper operation of an ABS even if the ABS is actuated in traveling in a 4WD mode. In order to reduce pressure in a piston chamber, a control circuit drives a motor for reverse rotation. As a result, a pressure difference between a piston chamber side pressure and a pump side pressure in a supply path becomes large, pressure oil on a piston chamber side in the supply path is instantaneously discharged to an outside from a releasing hole of a quick open valve, and the pressure in the piston chamber reduces instantaneously.

    摘要: A clutch shift modulation system is disclosed in operative relationship with a transmission having a torque input shaft and a torque receiving shaft. The transmission includes fluid pressure engaged forward and reverse clutches that may be engaged to drivingly rotate the receiving shaft in the respective forward or reverse direction when acted upon by fluid at a selected pressure, and a pump driven by the input shaft is adapted to supply fluid at this pressure to a shift valve which may be moved to a forward or reverse position to selectively connect the pump with the respective clutch through suitable conduits. A reversible pump driven by the receiving shaft pumps fluid in a direction and at a pressure which is a function of the rotative direction and speed of the receiving shaft and this reversible pump is connected between the two conduits leading from the valve to the two clutches so that during shifting it detracts from the efforts of the input driven pump to engage a particular clutch until the rotation of the receiving shaft in the respective opposite direction has slowed to below a selected speed and thereafter aids in the efforts of the input driven pump to engage this clutch.

    摘要: A power transmitting component can include a friction clutch, a ram, a pump, a fluid storage device and a valve. The ram can have a piston chamber and a piston movable therein between a first and second position to engage the friction clutch. A first inlet/outlet of the pump can be fluidly coupled to a reservoir. The fluid storage device can hold pressurized hydraulic fluid. The valve can be fluidly coupled with the piston chamber, a second inlet/outlet of the pump, and the fluid storage device. When in a first mode, the valve can permit fluid communication between the pump and the fluid storage device, inhibit fluid communication between the piston chamber and the pump, and inhibit fluid communication between the piston chamber and the fluid storage device. When in a second mode, the valve can permit fluid communication between the pump, the fluid storage device, and the piston chamber.
