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. A controller (108) applies a current through the electromagnet coils (98, 298) at the predetermined frequencies and frequencies relatively close to and above the predetermined frequencies for substantially preventing the magnetorheological fluid (68, 268) from flowing through the main fluid passage (104, 304) to force the magnetorheological fluid (68, 268) to flow substantially only through the rate dip track passage (120, 320) for preventing a sharp increase in the dynamic stiffness of the hydraulic mount apparatus (20, 220) from occurring at these frequencies.

Abstract: A hydraulic mount apparatus (20) for supporting a vibration source is disclosed. The mount apparatus (20) includes a housing (22) that defines a housing chamber (24) separated by a partition assembly (62) into a pumping chamber (64) and a receiving chamber (66), each containing a magnetorheological fluid (68). A flexible body (48) is partially disposed in the pumping chamber (64) for deforming elastically in response to vibrations caused by an external excitation. A fluid passage (106) extends between the pumping chamber (64) and the receiving chamber (66) for passing the fluid therebetween during low frequency vibrations. A piezostack actuator (118) partially extends into the pumping chamber (64) for moving within the pumping chamber (64) for varying the volume of the pumping chamber (64) to prevent a pressure increase in the pressure chamber to substantially cancel relatively high frequency vibrations.

Abstract: A fluid damper assembly for use in a vehicle includes a piston subassembly which includes a plurality of inflow passages and at least one rebound disk for restricting flow of hydraulic fluid through the inflow passages. A rod extends through the piston subassembly to actuate the piston subassembly between a rebound stroke and a compression stroke. An actuator supported by and within the rod includes a piezoelectric device and an amplifier for adjusting the damping force during the rebound stroke, thereby adjusting the suspension of the vehicle. A shaft within the rod is connected to a retainer to transmit motion from the amplifier to compress a spring and disengage the retainer from the rebound disk to allow the rebound disk to flex solely in response to hydraulic fluid pressure from the rebound stroke to open the inflow passages and reduce the damping force during the rebound stroke.

Abstract: A mount apparatus (20) for supporting a vibration source on a base is provided. The mount apparatus (20) includes a moving member (134) that is partially disposed in a pumping chamber (64) for moving within the pumping chamber (64) along a first axis (A) to create a volume change in the pumping chamber (64) to maintain the volume of the pumping chamber (64) to prevent a pressure increase in the pumping chamber (64) during the deformation of a flexible body (46) in response to an external excitation to effectively cancel the external excitation. The moving member (134) includes a moveable wall (144) of a flexible material, having a generally hour glass-shape in steady state, and extending between moving member upper and lower ends (140, 142). The moveable wall (144) flexes radially outwardly and inwardly relative to the first axis (A) in response to relative axial movement between the moving member upper and lower ends (140, 142), to amplify the volume change in the pumping chamber (64).

Abstract: A tie bar assembly (20) comprises a front unit (40) and a rear unit (28), each including an inner insert (32) interconnected with an outer insert (30) with webs (34, 42) of elastomeric material. A pole sub-assembly (52) is disposed between the units. The pole sub-assembly (52) and the units (28, 40) define front and rear fluid chambers (54, 56) containing magneto-rheological fluid (58). Fluid orifices (76) are disposed through the pole sub-assembly (52) for flow of the magneto-rheological fluid (58) between fluid chambers (54, 56). An electromagnet coil (84) generates an electromagnetic field to affect viscosity of the magneto-rheological fluid (58). A connecting rod (92) connects the inner insert (32) and the outer insert (30), and is slidably disposed through the pole sub-assembly (52) for causing movement of the magneto-rheological fluid (58) between fluid chambers (54, 56). A displacement sensor detects movement to generate a signal to the electromagnet coil (84). A front travel cushion (98) and a rear travel cushion (100) are respectively disposed on the inner insert (32) for limiting the movement of the inner insert (32) toward the pole sub-assembly (52).
