摘要： A powertrain mount is connectable between a vehicle's powertrain component and body structure. The powertrain mount includes a moveable core and a housing for the moveable core. The housing supports the moveable core for movement relative to the housing, in one or more open degrees of freedom, to one or more floating poses where the moveable core is rigidly mechanically decoupled from the housing in the open degrees of freedom. A magnetic field generation system includes one or more housing-side magnetic devices at the housing and one or more moveable-core-side magnetic devices at the moveable core. The housing-side magnetic devices and the moveable-core-side magnetic devices are configured to collectively generate mutually balanced magnetic fields between the housing and the moveable core in the open degrees of freedom that retentively locate the moveable core in one or more floating poses.

The second orifice has a first end positioned at the first side and has a second end positioned at the second side. The hydraulic-mount decoupler is operatively connected to the first orifice. The electric coil is disposed to magnetically influence the second orifice. The flexible membrane assembly has a first membrane portion fluidly-isolating, on the first side of the partition plate assembly, the first end from the first terminus and has a second membrane portion fluidly-isolating, on the second side of the partition plate assembly, the second end from the second terminus.

摘要： A system and method of controlling engine vibration mounted within a vehicle including at least one hydraulic mount, each mount including a fluid chamber. A pair of accelerometers sense relative acceleration across the mount between the engine and the frame and generate a relative acceleration signal. A control unit is electrically connected to the accelerometers. The control unit is adapted to generate an electronic control signal in response to the relative acceleration signal. The control device is responsive to the electric control signal for controlling the damping force of the hydraulic mount. A control algorithm calibrates the control unit such that maximum vibration damping occurs at and around the engine resonance bounce frequency.

摘要： A controllable valve assembly (18) applicable in Magnetorheological (MR) fluid devices (20), such as MR mounts and MR dampers. The valve assembly (18) includes a valve body (32) having a magnetic circuit (40) contained therein which carries magnetic flux .PHI., a controllable passageway (42) within the magnetic circuit (40), a MR (magnetically controlled) fluid (44) including soft-magnetic particles in a liquid carrier contained in the controllable passageway (42), a magnetic flux generator, such as a wound wire coil (46), generating magnetic flux .PHI. which is directed through the MR fluid (44) in the controllable passageway (42) thereby generating "rheology" changes causing restriction in flow of MR fluid (44) therethrough. In one aspect, a one-way check valve (34) is operative with a passive passageway (36) which is arranged in parallel relationship to the controllable passageway (42) provides "asymmetric" damping across the controllable valve (18) creating higher pressure differentials in a first direction and a lower in a second direction without "rapidly switching" the current to the coil (46). In another aspect, "asymmetric" damping is provided by a "changeable gap" formed by a moveable wall portion of the controllable passageway (42). In a third aspect, a first controllable passageway provides controllable flow in a first direction and a second controllable passageway provides controllable flow in a second direction, thereby provide "asymmetry." In a fourth aspect, "asymmetry" is provides by a "variable magnetic short" which changes magnetic circuit reluctance dependent on flow direction.
