Abstract: A hydraulic mount provides active control through the use of a rotary track assembly connecting a primary pumping chamber of the mount to a secondary fluid chamber. With low amplitude vibrations the fluid path remains open, providing low dynamic stiffness. For high amplitude vibrations, the fluid flow path is closed, providing a high level of dynamic stiffness. The rotary track assembly control is continuously variable offering a wide range of active control of hydraulic mount stiffness.

Abstract: A powertrain mount comprises an orifice plate including two tracks, a control track and an isolation track. The control track is spirally formed within the orifice plate, which has an exit and entrance on either side of the plate. The control track provides damping to control damping from engine bounce; whereas, the isolation track controllably provides dynamic rate dip. The isolation track is formed between an alignment plate and rotatable track member, each having an exit and entrance, respectively. The rotatable track member and the alignment plate are sealingly engaged and affixed to a decoupler and an annular area disposed about the orifice plate of the powertrain mount. The exit of the alignment plate is adjacent the decoupler. The rotatable track member forms a cavity with the molded body of the powertrain mount, with the entrance exposed to fluid within the cavity for controlling and minimizing vibrations within the powertrain. The isolation track has a track length that may be varied by rotation of the track member and its entrance. Various magnitudes of disturbance frequencies may be managed and controlled by either the fixed control track and/or the variable isolation track within the powertrain mount.

Abstract: A powertrain mount comprises an orifice plate and a rotatable track member. The orifice plate has an opening, a first surface sloping toward the opening, and an inner surface. The rotatable track member has an outer surface proximate the first surface of the orifice plate, and the outer surface of the rotatable track member has an opening. A compliant member is positioned adjacent the orifice track for isolating and damping amplitudes of vibration frequencies, as an amplitude dependent device. For small amplitudes, the compliant member takes up displaced fluid within the mount; whereas, large amplitudes the compliant member is bottomed out, forcing displaced fluid through the orifice track or into the molded assembly of the mount.

Abstract: 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.

Abstract: A hydraulic mount provides active control of dip rate performance through use of an orifice track connecting a primary pumping chamber of the mount to a secondary fluid chamber having a movable wall, and an actuator for regulating pressure applied to the movable wall for controlling movement of the movable wall. With little or no pressure applied to the movable wall, the mount provides significant isolation and very little damping in a predetermined and designed frequency range. As pressure is applied to the movable wall, the stiffness of the mount is increased significantly, to thereby provide substantial damping.

Abstract: A hydraulic mount for automotive engine and powertrain applications includes an elastomer body, a base and a partition interposed the body and the base to form a fluid-pumping chamber and a reservoir. Circumferentially spaced axial extending holes or slots or an annular orifice track are formed in the partition together with a magnetic coil operable to impose a magnetic field on the holes, slots or orifice track to control the shear properties of a magnetorheological (MR) fluid in the pumping chamber and reservoir. An elastomeric decoupler member is in communication with at least one of the pumping chamber and the reservoir to reduce the mount dynamic stiffness for isolating low-displacement relatively high-frequency vibrations. Vibrations of multiple frequencies may be isolated by tuning the mount with a controller.
