摘要： A method of controlling an automatic transmission is provided. The automatic transmission includes a piston having first and second surfaces opposite from each other, friction plates, engaging and disengaging hydraulic pressure chambers for supplying/discharging hydraulic pressure and directing the piston to push the friction plates to be engaged and disengaged, a hydraulic pressure control valve for supplying/discharging hydraulic pressure to/from the chambers, and first and second oil paths communicating the valve with the chambers. The second surface has a larger area for receiving hydraulic pressure than the first surface. The method includes controlling the disengaged friction plates to be engaged by adjusting the hydraulic pressure to a first pressure in a first period in response to a gear shift command and adjusting the hydraulic pressure to a second pressure in a second period. The first pressure is changed depending on a state of the automatic transmission.

摘要： A clutch device for a clutch system has an input member that rotates at a first speed. A friction drive system is disposed between the input member and an output member. The clutch device is selectively movable by a fluid actuator assembly, between an engaged position in which the friction drive system drives the output member to rotate at the first speed, and a disengaged position in which a viscous drive system rotates the output member at a second speed slower than the first speed. A variable viscous fluid supply assembly includes a viscous fluid storage chamber, a valve, and a valve actuator that selectively drives the valve to move between an open position and a closed position to control an amount of viscous fluid available to the viscous drive system, thereby varying the second speed.

摘要： A vehicle driving apparatus includes a rotating electrical machine and an engagement device, which are disposed on a power transmission path linking an input member drive-coupled to an internal combustion engine and an output member drive-coupled to a wheel. The engagement device includes an engagement input coupled to the input member, an engagement output that forms a pair with the engagement input and is coupled to the rotating electrical machine, a friction member disposed between the engagement input and the engagement output, and a pressing member that presses the friction member in a pressing direction. An oil pressure chamber is formed between the pressing member and either the engagement input or the engagement output. A biasing spring biases the pressing member in the pressing direction when no oil pressure is supplied to the oil pressure chamber and is disposed on an exterior of the oil pressure chamber.

摘要： A selectively operable one-way torque-transmitting mechanism has a friction actuator, which is operable to adjust the position of torque-transmitting members between the inner and outer race of the selectable one-way torque-transmitting mechanism. In an unactuated position of the friction actuator, the torque-transmitting members will permit rotation in one direction and prevent rotation in the opposite direction. In the actuated position, the torque-transmitting directional functions are reversed.

摘要： A frictional resistance coupling comprises an outer part and an inner part, which are connected to each other in a pressure-tight manner and between them form an inner chamber with a conical surface and a likewise conical, axially displaceable annular piston. The annular piston is moved axially due to the supply of pressure medium, for producing a radial tension and frictional resistance between two parts, e.g., a coupling and a shaft. Serving for determining the axial position of the enclosed annular piston is an axially disposed transmitter cylinder, which is connected to a receiver cylinder in the region of the outer surface of the coupling, by way of an incompressible medium. The piston of the receiver cylinder supports an indicator, whereof the position is monitored by an external sensor. The transmitter cylinder and receiver cylinder form a hydraulic linkage, preferably with displacement translation for monitoring even small piston movements with reliable control of whether the annular piston has reached its end position. For this purpose, the sensor monitors the position of the indicator attached to the receiver piston, on the outer periphery of the coupling.

摘要： A pneumatically engageable clutch for coupling a rotating shaft with a rotatable member comprises a compressed air passage in the rotating shaft. The compressed air passage opens in a port in the peripheral surface of the shaft. A stationary casing surrounds the shaft and has an annular chamber adjacent the port, compressed air being supplied to the annular chamber. The annular chamber is sealed by packing rings, such as Simmer rings, made of elastomeric material an engaging the shaft. To reduce the pressure difference across the packing rings, hydraulic pressure is applied to the outsides of the packing rings. Control means keep the hydraulic pressure substantially equal to the compressed air pressure. In one embodiment, the control means comprise a slide valve. In another embodiment, the control means comprise a partially oil-filled closed system which includes chambers axially outside of the packing rings, the compressed air pressure acting statically on the oil level.
