A pair of accelerometers sense relative acceleration across the mount between the engine and the frame and generate a 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 engine mount includes an orifice track formed in a partition between an elastomer body and a base member of the mount, the partition being formed by two separable orifice plates. An annular fluid filled tuning chamber is disposed adjacent the orifice track and separated therefrom by a flexible membrane. An actuator is in communication with the tuning chamber for forcing pressure fluid into or out of the chamber to selectively deflect or distend the membrane to modify the cross sectional area of the orifice track and the vibration damping characteristics of the mount.

摘要： A hydraulic mount assembly includes a body with a main chamber formed therein. A magnetorheological fluid retaining member is positioned in the main chamber forming a magnetorheological chamber adjacent the main chamber. An electrical coil is positioned adjacent the magnetorheological chamber and a plate member is operably connected to the magnetorheological fluid retaining member. Energization and de-energization of the coil controls the ability of the mount to resist movement by varying the apparent viscosity of the fluid within the magnetorheological chamber.

摘要： 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.

摘要： A hydraulic mount for an automotive vehicle or machine includes opposed mounting members secured to an elastomeric body and a base, respectively. An orifice plate assembly is interposed the body and the base to define a pumping chamber and a reservoir for fluid to flow therebetween through an orifice track of the orifice plate assembly. An electroactive polymer decoupler member is secured in a cavity formed between two orifice plates of the orifice plate assembly. The decoupler member is operably connected to a controller for imposing an electric field on the decoupler member to change its shape and thereby selectively vary the dynamic stiffness of the mount.

摘要： A hydraulic engine mount includes opposed mounting members secured to an elastomeric body and a base, respectively, and an orifice plate assembly interposed the body and the base to define a pumping chamber and a reservoir or opposed pumping chambers for fluid to flow therebetween through an orifice track formed by the orifice plate assembly. One or two elastomeric decoupler discs may be secured in recesses between two orifice plates of the orifice plate assembly and form spaces which are operable to be in communication with a vacuum source to impose vacuum pressure on the decouplers at selected frequencies as controlled by solenoid operated valves and a controller. The mount may be operated at a substantially reduced dynamic stiffness lower than the static stiffness of the mount to provide improved low amplitude vibration isolation, in particular.

摘要： 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.
