  • Patent number: 10767722
    Abstract: Flows of magnetorheological fluid inside a mount are controlled to be stopped in the direction of the axis of the mount and in directions perpendicular to the axis by applying coil excitation current to an exciting coil, and thus the elastic properties of the mount are adjusted such that the mount is hardened in the axial direction and in the directions perpendicular to the axis. As a result, a variable damping force can be exerted on the external forces applied to the mount in the axial direction and in the directions perpendicular to the axis.

  • Patent number: 10422405
    Abstract: A system and a method that isolate a payload from the effects of vibrations by providing an active feedback path that enhances the isolation performance of a passive vibration isolation system at all relevant frequencies. The system comprises a kinematic arrangement of three bipod pairs of hybrid isolation struts to produce a fully kinematic suspension system. The active enhancement mechanism incorporates accelerometer feedback on each of the six hybrid isolation struts, blended with relative displacement measurements, to produce a transfer function that provides a specified alignment of a suspended component (with another component) at low frequency, but inertial stabilization at high frequency. Passive roll-off is produced by a series of disc flexures in each hybrid isolation strut.

  • Patent number: 9057417
    Abstract: To provide a vibration isolation unit capable of reducing the number of parts, man-hour and material cost, and suppressing the product cost. One side of a stopper rubber member continues to the outer edge of a diaphragm. Accordingly, because they can be vulcanizingly molded simultaneously, the number of parts can be reduced. Also, because the diaphragm is attached to an outer tube member, the stopper rubber member also can be fixed simultaneously, and therefore the man-hour can be reduced. Further, because one side of the stopper rubber member continues to the outer edge of the diaphragm, overlapping of them in an axial view can be avoided, and a rubber material can be used efficiently. Thus, the number of parts, man-hour and material cost can be reduced and the product cost of the overall vibration isolation unit can be suppressed.

  • Patent number: 9051989
    Abstract: A magnetorheological fluid-based hydraulic mount apparatus (20, 220) for supporting a vibration source on a base is disclosed. A main fluid passage (104, 304) extends between pumping chamber (64, 264) and receiving chamber (66, 266) for passing the fluid therebetween. Electromagnet coil (98, 298) variably generates a magnetic flux across the main fluid passage to variably change the damping stiffness of the mount. A rate dip track passage (120, 320) extends between the pumping chamber (64, 264) and receiving chamber (66, 266) for oscillating the magnetorheological fluid (68, 268) therethrough to decrease the dynamic stiffness of the mount apparatus (20, 220) at predetermined frequencies.

  • Patent number: 9022368
    Abstract: A switchable, hydraulic damping mount includes a work chamber filled with hydraulic fluid and a compensation chamber connected to the work chamber via a channel. A partition wall mutually separates the chambers. A ferromagnetic diaphragm is arranged in the partition wall and is deflectable. An electromagnetic switching actuator has a deenergized state and an energized state and controls the diaphragm. The switching actuator applies a magnetic holding force to the diaphragm and fixes the diaphragm in a rest position when the switching actuator is in the deenergized state and reduces the magnetic holding force to such an extent that the diaphragm is enabled for movement in the longitudinal direction of the mount when the switching actuator is in the energized state.

  • Patent number: 8998187
    Abstract: A two vacuum actuated switch mechanism is provided within an engine or hydromount. First and second ports are provided along a peripheral portion of an inertia track assembly. A decoupler or vacuum diaphragm is selectively exposed to vacuum through a first port. Under the influence of the vacuum, the decoupler can no longer oscillate. If vacuum is applied only to the decoupler, and not and idle diaphragm, the fluid is forced through a low frequency inertia track which creates high levels of damping and low frequencies. If vacuum is also applied to the decoupler and the idle diaphragm, the high frequency inertia track is opened and causes the fluid to flow therethrough. This creates a high frequency dynamic rate dip. Alternatively, if no vacuum is applied to either the decoupler or the idle diaphragm, the decoupler is allowed to freely oscillate creating a decoupled state for low input displacements. Higher input displacements results in fluids being forced through the low frequency inertia track.

  • Publication number: 20150091228
    Abstract: A spring-damper system for use in bearings or as a damper, in particular as a spring-damper system in active engine bearings includes a coupling device which can be coupled to a load and to a supporting device at a bearing or damping point, in order to mount the load in such a way that it can vibrate on the supporting device. The coupling device is designed to transmit a load input generated by the load substantially without loss to a spring-damper device and to absorb a reaction thereto by the spring-damper device and to feed said reaction back to the load, in order to counteract the load input in a vibration-damping fashion. In this context, the spring-damper device can be arranged and/or is arranged spatially separate from the bearing or damping point.

  • Patent number: 8936235
    Abstract: A fluid-filled type vibration damping device including a base component and a tubular mating component. The tubular mating component is externally fitted onto the base component by means of a diameter-constricting caulking with a sealing rubber clasped therebetween so as to constitute a mate-fastened portion. The tubular mating component extends axially outward beyond a sealed section of the mate-fastened portion so as to provide a caulking tube portion. A diametrical position of the tubular mating component at the sealed section is determined by contact of the caulking tube portion against an outside peripheral face of a positioning projection provided on the base component so as to define a diametrical positioning portion. The caulking tube portion is constricted in diameter and held in engagement with an axial edge portion of the positioning projection so as to form an axial positioning portion.
