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 hydraulic mount is provided having a body with first and second fluid chambers and a decoupler subassembly interposed between to partially define the first and second fluid chambers. The decoupler subassembly comprises first and second flexible decoupler members operatively sealed together to form a third fluid chamber. The first and second chambers may be substantially filled with a magneto-rheological fluid. The third chamber may be filled with a standard hydraulic fluid, like glycol.

摘要： To be able to exhibit precise and sufficient vibration damping performance with regard to vibration not only in the low frequency region but also a wide range of high frequencies with less power consumption, an MR fluid pathway 9 for hermetically sealing and holding the MR fluid 8 is formed to be of crankshaft shape in cross section with vertical pathway portions 9A, 9B and horizontal pathway portions 9C, the pathway being between a piston-shaped member 6 and a cylindrical member 7 capable of displacing relative to each other in the direction of elastic deformation of the elastomer 5 due to applied vibration, an electromagnet 10 capable of forming a magnetic field across the horizontal pathway portions 9C of the pathway 9, controlling the amplitude of the magnetic field to thereby change the viscosity of the MR fluid 8, fixed and supported on the piston-shaped member 6.

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.
