    摘要： A hydraulic power booster for a brake apply system includes a mechanically actuated hydraulic booster of compact design that can be integrated in line with a conventional type master cylinder. Additionally, a combination of twin mechanically actuated check valves is arranged to provide a structure with essentially no leakage when the hydraulic booster is at rest and when the hydraulic booster is at poise. A mechanically actuated check valve is normally held open and is positioned in a passageway between the power piston and a fluid reservoir. This check valve is substantially, immediately closed upon the application of force to the brake pedal. Another mechanically actuated check valve is provided in a passageway between the hydraulic power supply and the power piston. This check valve is mechanically opened to supply a selected amount of pressurized fluid to the power piston which generates a selected amount of vehicle braking in response to actuation of the brake pedal.

    摘要： A split rotor cooling fan clutch includes an input member that is constantly driven at engine speed, or at some selected proportion thereof. An output member is journaled on the input member so as to be supported thereon in a substantially nonrotating state when decoupled and alternately, to be concentrically rotatable in concert therewith at a variety of speeds. A space presented between the input and output members contains a quantity of magnetorheological fluid. An engagement mechanism includes the split rotor and coil, with a ferromagnetic element positioned to define an operative gap between the rotor and the ferromagnetic element. The coil is selectively energized with a given current to result in a torque transfer between the input and output elements that provides a rotational speed of the fan tailored to the cooling requirements of the associated engine. Internal heat generation is managed electronically to prevent overheating.

    摘要： A monotube suspension damper including a cylinder tube having a fluid chamber and a gas chamber, a piston dividing the fluid chamber into a compression chamber and a rebound chamber, a primary fluid flow path across the piston including flow control valves which throttle fluid flow, a secondary fluid flow path across the piston parallel to the primary flow path including flow control valves which throttle fluid flow, and a tubular connecting rod on the cylinder tube connected to the piston. A valve spool is supported on the piston for linear translation between closed and open positions blocking and unblocking the secondary flow path. A control rod inside of the connecting rod is disposed between the valve spool and a flexible diaphragm exposed to pneumatic pressure in an expansible load leveling chamber between sprung and unsprung masses of the motor vehicle. As the pneumatic pressure in the expansible chamber varies, the control rod transfers flexure of the diaphragm to the valve spool to close the secondary flow path and increase the stiffness of the suspension damper as pneumatic pressure increases and to open the secondary flow path and decrease the stiffness of the suspension damper as pneumatic pressure decreases.

    摘要： A braking system generally provides pressure equalization between the sides of a split braking circuit. The amount of equalization provided is limited to enable the introduction of purposely induced pressure variances. A result is that unintentional pressure variations are moderated and intentional target pressure variations are easily obtainable. The braking system provides power braking operation in response to a manually actuated master cylinder. Fluid pressure is transmitted through isolation valves directly to the wheel brakes. The braking system also provides power operation in response to a powered pump. The pump delivers pressurized fluid through a controllable supply valve. When the supply valve is open, the isolation valve(s) are shifted to provide open fluid communication path between proportional pressure control valves and the wheel brakes. The pressure equalization effecting device is isolated from the master cylinder pressurized circuit during base brake operation.

    摘要： A hydraulic mount is operable in soft and firm modes and includes a valve positioned at the partition between the working chamber and the reservoir. A normally open fluid path extends through the partition and opens between the working chamber and the reservoir for soft operational characteristics useful in attenuating low amplitude vibrations. The valve body and the partition together define a control chamber in the fluid path. The control chamber is open to the reservoir through lateral openings in the valve body so that fluid pressure in the control chamber is approximately at atmospheric pressure so that a small actuator can move the valve. When the valve is closed the fluid path is closed for firm operational characteristics in controlling large amplitude inputs such as those from torque transients.

    摘要： A magnetorheological fluid fan clutch effects modulated rotational motion transmission between a rotatable input shaft carrying an input clutch plate and a housing having a front cover and a rear cover forming a cavity about the input clutch plate wherein the front and rear covers operate as output clutch plates. A nonmagnetic spacer is positioned between the front and rear covers and radially outside the input clutch plate. A bearing supports the housing on the input shaft through the rear cover so that the input clutch plate is rotatable on the input shaft relative to the housing. Magnetorheological fluid is carried in the cavity, through which torque is variably transferred between the input clutch plate and the housing. A coil is positioned radially outside the nonmagnetic spacer and carries a variable electrical current to effect a variable magnetic field across the input clutch plate and through the magnetorheological fluid providing modulated torque transmission between the input clutch plate and the housing.
