摘要： A hydraulic mount includes a mounting plate and a wall, with a working chamber defined between the mounting plate and the wall. The mounting plate and the wall are separated by a relatively thick elastomeric element so that the size of the working chamber varies as the elastomeric element is compressed and expanded by operation of the mounting plate and the wall moving closer together and farther apart. A reservoir is defined substantially by the elastomeric element in combination with a relatively flexible diaphragm that extends between the mounting plate and the wall so that the reservoir is generally annular in shape and is positioned around the working chamber. The elastomeric element serves as a separation wall between the working chamber and the reservoir. The mount includes a fluid track extending through the wall and opening between the working chamber and the reservoir, with a fluid contained in the working chamber, the reservoir and the fluid track, so that the mount is tunable by varying the size of the fluid track.

摘要： In a duo-pumping hydraulic mount, two acting pistons are employed, one associated with each working chamber. The pistons are rigidly connected. During operation, internal pressures generated in each chamber are opposite in sign with one being negative and the other being positive. Therefore, to achieve a given pressure differential across the fluid track, the magnitude of the pressure in each working chamber is half what would be experienced in a conventional single pumping mount. Durability is improved by reducing internal pressures and by distributing kinetic loads to two rubber elements so that individual stresses are minimized. An individual load bearing element supports static loads on the mount.

摘要： A damper for damping movement of a shaft, the damper including a housing having an inner surface defining a chamber and a rotor rotatably mounted in the chamber. The chamber is filled with magnetorheological fluid such that when the rotor is moved in the chamber the magnetorheological fluid damps the movement of the rotor. The rotor has an outer surface adjacent to and spaced apart from the inner surface. The damper further comprises shaft coupled to the rotor and an outer magnet adjacent the space between the outer surface and the inner surface for restricting the flow of the magnetorheological fluid in the space between the outer surface and the inner surface.

摘要： A passive magnetorheological clutch includes an input member that is constantly driven at engine speed, or some selected proportion thereof. An output member is journaled on the input member so as to be supported thereon in a nonrotating state and to be concentrically rotatable in concert therewith. A space presented between the input and output members contains a quantity of magnetorheological fluid. The space also contains an engagement mechanism including a permanent magnet and a ferromagnetic ring concentrically positioned with an operative gap therebetween, wherein the operative gap's dimension is variable to effect changes in the magnetic field passing between the magnet and the ring. When an actuator effects a reduction in the distance between the magnet and ring, the amount of magnetic field increases in density adjacent the ring. The resultant torque transfer from the input member to the output member is effected across the operative gap and through the magnetorheological fluid. As the operative gap is reduced, the torque transfer increases in a gradual and progressive manner.

摘要： A proportional fluid pressure regulation system is provided using a combination of a proportional valve and a shuttle valve for fluid flow control. A system of fluid pressure regulation is achieved where the desired pressure output is provided by one of two pressure input sources. The two pressure input sources are alternately selected by operation of a pilot operated shuttle valve and a solenoid operated proportional valve. The two pressure sources may comprise a manually actuated vehicle braking system's master cylinder and a power operated fluid pump.

摘要： A damper includes a piston that carries a relatively compact control valve for controlling fluid flow through the piston. The control valve provides a variable amount of damping by regulating damper fluid flow between the extension chamber and the compression chamber of the damper during extension and compression strokes. Pressure regulation across the piston is controlled through two alternate flow paths as determined by the control valve. Damping through the first flow path is relatively soft and is determined according to the deflective characteristics of a single bi-directional annular disc valve. Damping through the second flow path is relatively firm and is determined by the first bi-directional single annular disc and a second bi-directional single annular disc in series.

摘要： An improved magnetorheological fluid pumping system and method are provided which effectively dispense a predetermined amount of magnetorheological fluid for delivery to a MR device such as a damper assembly, for example, during manufacture. The fluid pumping system includes a pump having inlet and outlet valves, a reciprocally mounted piston, a stroke operator device for controlling the movement of the piston and an electronic controller for operating the stroke operator device and the inlet and outlet valves. Importantly, the inlet and outlet valves include an annular flow gap and a magnetic field generating assembly operable in an energized state to generate a magnetic field across the flow gap to cause magnetorheological fluid flowing through the gap to experience a magnetorheological effect sufficient to prevent flow through the gap and in a de-energized state to permit flow through the gap. In one embodiment, the system includes inlet and outlet valves mounted at one end of a pump housing on opposite sides of a common feed chamber to control fluid flow into and out of a pump chamber. In a second embodiment, the system includes an inlet valve integrated into the piston for controlling flow between a receiving chamber on one side of the piston and the pump chamber on the opposite side of the piston. The valves are alternately energized and de-energized before retraction and dispensing strokes of the piston resulting in simple effective control of fluid dispensing.

摘要： A novel and improved magnetorheological fluid damper is provided which effectively secures a flux ring to a piston core in a manner which prevents relative axial and radial movement between the flux ring and the core throughout operation while minimizing the size of the piston assembly yet providing effective damping. Several connector devices are disclosed for both axially and radially securing the flux ring relative to the piston core at one end of the piston assembly in a simple manner without increasing the length of the piston assembly. The connector device may include an outer portion brazed to the flux ring, an inner portion connected to the piston core, bridge portions extending between the outer and inner portions, flow passages formed between the bridge portions and an inlet cavity formed adjacent an annular flow gap to permit unimpeded, enhanced laminar flow through the flow gap by improving the damping effect. Other connector devices may include elongated rivets extending through the flow gap axially along the piston assembly, and elongated pin and spacer tube connectors extending radially between the piston core and the flux ring. Various embodiments of radial support devices are disclosed for possible use in combination with the connector devices to enhance radial support by, for example, the use of balls, a washer with tabs, a coil bobbin with tabs, rivets and axially extending elongated pins.

摘要： A monotube damper and suspension spring assembly for a motor vehicle includes a tubular housing defining a chamber filled with damping fluid. A piston and piston rod reciprocate within the chamber. In order to compensate for volumetric changes of the chamber due to extension and retraction of the piston rod within the chamber, either the upper seal cover or lower bottom ring assembly is slidable within the housing. A preload is applied either to the housing or to the seal cover to thereby bias these elements to compensate for volumetric changes in the chamber.
