Abstract: A control system for an active powertrain mount includes a control signal which is based on the input velocity of the chassis at the active powertrain mount. The control signal may be proportional to the input velocity or to the mount velocity, which is the difference between the input velocity of the chassis at the active powertrain mount and the output velocity of the powertrain component at the active powertrain mount. The input velocity of the chassis at the active powertrain mount may be determined by a controller based on the CG heave and the roll and pitch velocities of the chassis. The output velocity of the powertrain component at the active powertrain mount is determined by the controller by integrating an acceleration signal from a component accelerometer disposed on the powertrain component proximate to the active powertrain mount. Corresponding methods for controlling an active powertrain mount are also provided.

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 top mount assembly including a housing for being connected to the frame of the vehicle. A rod connection assembly is disposed in the housing for being attached to a piston rod of the damper assembly. A chamber is defined between the rod connection assembly and the housing for receiving a fluid. A resilient member is disposed between the rod connection assembly and the housing. A partition assembly is positioned between the resilient member and the housing and axially divides the chamber into an upper chamber region and a lower chamber region. The partition assembly defines at least one passage that extends between the upper chamber region and the lower chamber region. At least one electromagnetic coil is disposed adjacent to the passage for selectively modifying the characteristics of the fluid passing through the passage to modify the damping characteristics of the top mount assembly.

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 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 tie bar assembly includes front and rear units each including inner inserts interconnected with outer inserts with webs of elastomeric material. A pole sub-assembly is disposed between the units. The pole sub-assembly and the units define front and rear fluid chambers containing a magneto-rheological fluid. Fluid orifices are disposed through the pole sub-assembly for flow of the magneto-rheological fluid between fluid chambers. An electromagnet coil generates an electromagnetic field to affect viscosity of the magneto-rheological fluid. A connecting rod connects inner inserts and is slidably disposed through the pole sub-assembly for causing movement of the magneto-rheological fluid between fluid chambers. A displacement sensor detects movement to generate a signal to the electromagnet coil. Front and rear travel cushions are each disposed on the inner inserts for limiting the movement of the inner inserts toward the pole sub-assembly.
